1: The copper coil lays in the paperclip cradle that is connected
to a battery which forms a complete circuit. Half of the wire insulation
is shaved off of the ends of the wire that are laying in the paperclip
cradle. The insulated half of the wires cut off the circuit but the
magnet attracks the side that is opposite and pulls the copper coil over
and a momentum is formed continuing the coil to turn.
2: I finally understand why a compass works. I never knew that
the north pole is really the south pole. The idea that a compass pointed
north and to the north pole made sense but after thinking about it in
terms of magnets, I am glad for the magnet explaination.
3: I cannot think of a new one!
4: Yes they are and it is nice to have one set so you can model
what to buy for the project again so there is enough for a class to do
the experiement.
5: I like doing the experiement and then talking about why they
work.
6: We usually don't talk about our preflights so I am not sure
how helpful they are...
7: Sometimes I think lecture should go over more of the actual
homeowrk questions. The lab on gravity, I thought I understood, and then
I missed several questions.
8: It is a lot of what I expected because I had friends who took
this specific course and told me about it. Also, the things we covered
are similar to high school physics. It is nice to have a refresher
course geared towards teaching the material!
lecture preflight 11
1: The motor we made in class works because of the electric
current that runs through the copper wire. When we scraped off the top
half of the insulation, that half was able to conduct electricty and
cause the copper wire to become a magnet. By placing a magnet below the
copper coil, the two magnets, attracted by one another, caused the coil
to move. However, once the wire is turned around and the insulated side
is touching the paperclips, the momentum continues to turn the coil
around even though the magnet is off. This makes the coil spin.
2: Neodymium magnets are CRAZY hard to get apart!
3: How does the radio work?
4: I think so. They will be helpful for me when I am trying to
come up with ideas for lessons in the future and will probably help me
to remember key aspects of the concepts as well.
5: Re-learning the simple stuff I may have to teach someday.
6: Lectures are fun, but I feel like it jumps to quickly from one
topic to another and I often get confused.
7: More focus on how things actually work rather than showing so
many demonstrations.
8: So many of my friends who have taken the class in past
semester really enjoyed it and so did I. I really liked how the class
was set up and I had a lot of fun with such a fun professor!

3:
4: I think the materials we recieved throughout the semester were
great. It's a great resource for when we are actually in the classroom
in a few years. We can look back at the simple things we were given to
learn different physics concepts and apply those and use them in our
lesson plans, etc. I think the hands on approach that we used in this
class is also really helpful, because nowadays teachers are really
encouraged to make hands on lessons for their students.
5: I think the review of general physics concepts was really
helpful. I took physics in my sophomore year of highschool and had
forgotten alot of things. This class was a good refresher. It also
helped with learning how to encorporate physics into a classroom, even
if I personally am not a physics genius.
6:
7: I think the Wednesday lecture is fun and provides more insight
into concepts that we probably would not even learn or talk about again
(since alot teachers aren't teaching physics).
8: I think I expected alot more studying and frustration while
learning concpets. Physics in highschool was sort of difficult, but this
class made it more simple to understand.
lecture preflight 11
1: it worked because the top half exerted a magnetic charge, but
the bottom half did not, so as the charge kept changing the coil spun to
adapt to each change
2: the difference between the geographical north pole and the
magnetic north pole
3: how do credit cards use magnets?
4: the only thing i have used at home are the magnets and the
stop watch. i don't think they need to be improved, i really like the
box!
5: the most useful aspect was the in class discussions and the
answering of questions we had during discussion, it was useful to get to
experience and play with all the materials for ourselves
6: the least useful aspect was the amount of time that was wasted
between each experiment or activity
7: i thought the Wednesday lectures were more intresting than
useful..I rarely learned things i didn't know already, but it was fun to
watch the demonstrations.
8: yes, it was. it was alot more based on learning and teaching
than evaluating
lecture preflight 11
1: Current flows from the positive end of the battery and hits
the paperclip. Then, the paper clip sends current to the stripped side
of the wire. This current flows through the wire and causes it to
rotate. If both sides of the wire were stripped, then the rotation would
not occur. Finally, current flows through the wire and back to the
paperclip, which in turn sends current through the negative end of the
battery.
2: The North Pole geographically is the South Pole magnetically.
3: How do DVD players work?
4: Yes they're very useful. It may be helpful if we got baggies
to bring home anything that had many pieces...like the motot.
5: The materials that we get in lab.
6: I don't think there is a least useful aspect...everything is
useful.
7: I wish it was related a bit more to actually teaching physics.
8: The lab is what I expected, but the lecture is not. I wish
we'd discuss more physics-related science classes.
lecture preflight 11
1: We could not get it to work.
2: That a magnet when suspensed will always point the right
direction.
3: How do volcanos work?
4: I think that the material in the class are useful. It is
interesting what we cover.
5: I think that the lab is the most useful. It is important to
see these things hands on.
6: The least useful aspect of Physic 123 was the weekly homework.
It was actually just my least favorite of the class.
7: I like to see the professor do a variety of experiments. I do
not think it really needs to be improved.
8: I did not really have any expectations. It is acually more
interesting that I first thought.
lecture preflight 11
1: The charge makes the wire a magnet but it goes on and off
(because we only shaved 1/2 of the protection stuff off) and so it
sometimes is repulsed and attracted to the magnet, and sometimes not.
Then it moves.
2: Wire motors!
3: How do DVDs work?
4: Not really-- I'm not going to go on to teach this, so it
doesn't really help to have this stuff. However, I love the stop watch.
Otherwise, I'm probably going to get rid of it, honestly.
5: Reminding me of the stuff I had forgotten from high school.
6: Wasting my time during the labs, waiting for people who are
scared to answer questions to answer them. I learned a lot, but it took
a while to get there. Joel talked a lot and sometimes got confused.
7: It was so late in the day, and only once a week, so I forgot
to go sometimes. I enjoyed it when I went but in the middle of the week,
it's hard to remember something at 4 pm. Maybe if there were some bonus
points for attending or something? But that wouldn't help me remember;
it would just make me feel worse for forgetting.
8: It's what I expected, but my roommate took it last year, so I
heard first hand her experiences.
lecture preflight 11
1: The motor worked like a switch would have worked if you stood
there and turned it on and off. As it rotated, when the side of the wire
that was stripped came in contact with the metal of the paperclip, it
sent the electric energy from the battery through the wire and came in
contact with the magnet, repelling it.
2: I thought it was really interesting how the magnets were
strong enough to go through your hand and you could do a magic trick :)
3: How is paper recycled?
4: Yes, I thought the materials we kept from class were very
useful. One day, in my own classroom, I will be able to look back and
use these materials to teach my own lessons.
5: I thought the review of simple concepts that I had forgotten
since elementary school was very useful. It is these simple ideas that
are most easily forgotten and hardest to explain when students come and
ask.
6: I don't think there was a least useful part.
7: I found the Wednesday lecture very intersting. We were able to
view science in different demos that we can't do ourselves because we
dont have the necessary supplies. It helped a lot to be able to visual
the concepts.
8: Physics 123 was not quiet what I expected. When you see
"Physics" on your schedule, the word itself is pretty intimidating. I
took physics in high school and it was pretty painful, so I was
expecting this to be the same. However, this class turned out to be very
enjoyable and I learned a lot from it that I will actually be able to
use in the future.
lecture preflight 11
1: Since the wire was half exposed it was only magnetized on one
side and it was able to spin
2: that the geographic poles are opposite of what we call north
and south poles
3: why do you have to ground the cable when you jump start a car
4: Yes, i think they will be beneficial for my classroom
5: Clearing up my own misconceptions about science
6: Nothing really.
7: Yes, i enjoy it because it's similar to Mythbusters. I think
that I'm challenged as well as entertained.
8: Yes, it was what I expected because my friends have taken it
before and told me how great it was!
lecture preflight 11
1: The electric current pushed the wire one way and then the
magnet kicked in and made it rotate again, and it just constantly does
that.
2: The north pole actually is the south pole.
3: How to tidal forces work?
4: Yes, they are useful. They don't need any impovement.
5: I have a better grasp on science and I have some fun ideas I
can use when I'm teaching.
6: It was all useful.
7: The lectures are very useful and interesing. The only way to
improve them would be to get credit for coming.
8: It was different. Someone told me that the labs only took an
hour maximum to complete, but most of the labs seemed to drag on and
take a really long time.
lecture preflight 11
1: First a powered battery was hookep up to 2 paper clips, using
the clips coming out of the battery (This current of the battery clips
attatched to the metal paper clips generated power). A loop of wire was
then hung from the 2 paper clips, wih a magnet placed below the loop.
The lip began to spin. This moor occured becasue the power generated
from the battery heated up the wire loop and then conncted with the
power of the magnet, causing the loop to spin.
2: I enjoyed learning about the concept of the earth being one
giant magnet, and how th enorth and south pole act as magnets to make
the earth rotate.
3: Will the earth ever stop spinning?
4: I would call the materials that we kept from class fun, but
not very useful. I would suggest that the things we are able to bring
home have some sort of practical use in our daily lives. This way, they
can be fun and useful.
5: The most useful aspect of Physics 123 is learning basic
concepts of physics that most people don't know, but should know. I
enjoy how these concepts are really put into action by allowing us to
use hands-on demonstrations while learning such concepts.
6: The only thing I would say is that there was too much down
time during class. When we learned a concept and were given directions
to complete an activity, too much time was taken until we began to out
discussions.
7: There definetly needs to be more of an incentive to come to
the Wed. lecture. While it was fun and useful, It seemed to be pretty
empty at times.
8: After hearing descriptions of this class from friends who were
previously enrolled, Physics 123 is pretty much what I expected: just a
fun class where you learn about the interworkings of every day
phenomenons. Good stuff!
lecture preflight 11
1: The current was going from the battery, to the paper clip,
through the copper wire, through the other paper clip and back to the
battery completing the circuit. The copper wire had the insulation
shaved off only half the wire. So, when the copper circle was facing up
or down, the opposite part of the magnet was attracted to it causing it
to flip. Once the copper circle flipped the unshaven part of the wire
was now touching the paper clip cutting off the circuit. The copper
circle continued to move just because of momentum and then, when it
flipped, it was back on the part of the wire that had the insulation
that was shaved off. It continued in this cycle.
2: I learned how to make a simple motor. It was exciting!! Mine
actually spun. :-)
3: How serious is the issue of global warming?
4: Yes, they are. I can use them in my classroom someday. I
should have, however, kept a list of all the materials and their uses
just to make sure I will remember what everything was for.
5: Learning physics at a more practical/hands-on/connected to
real life situations level and in a way in which I can use in my
classroom one day.
6: There was no least useful aspect...I found this class to be
very entertaining and practical. I wish all my classes were like this.
7: Yes I do find it useful. I love the demos and I like that the
questions from the homework are gone over. If lecture was at a different
time it would be better. Having lecture so late in the day is rough.
8: Yes, it was everything I expected and heard about. This is a
very popular class and now I understand why.
lecture preflight 11
1: When the battery is connected to the coiled wire it causes a
current to start running through it. This current causes the wire to
become polarized. This causes the wire to be attracted to the magnet
below it. This attaction causes it to flip in circles.
2: I learned that I am not very found of magnets! because I had
such a difficult time getting everything in this week's lab to work
correctly!
3: What came first the chicken or the egg?
4: I think the materials we keep from class are useful and they
will be great tools to use when someday we go into the classroom!
5: I think for the most part the labs are the most useful because
they are hands on and we learn by exploring the material. Its useful
because all the activities build on one another and become more
challening.
6: Sometimes the explanations in lab are not really that clear.
Or we go into way more detail then we need and it is confusing!
7: I think lecture was helpful and very fun. I really liked all
the demonstrations. Maybe one thing that could be done to change it is
not talk just on the homework questions. It seems like sometime we spend
the whole lecture just going over the homework questions.
8: Physics 123 is pretty much what I was expecting.
lecture preflight 11
1: The electricity is sent through the paper clips to the wire
and the insulated part of the wire makes it act like an electric motor
and turns the wire. Then the not insulted part stops it but then it
turns back to the insulted part and goes on/off/on/off... etc and that
is why it should keep turning.
2: I learned about the North Pole and South Poles of the Earth
and how they act like a huge magnet with the South end at the North and
North end in the South.
3: What happened if the poles of the Earth stopped being magnetic
like they are.
4: They are ok. The stop watch was great, I use that a lot, the
others are cool at first but I don't really use them.
5: I enjoy the labs being hands out so we are acually doing the
activities and seeing what happens which makes what happens more
worthwhile and will last with me longer.
6: Nothing really, the class is great!
7: Yes, it was fun and there was some very cool activities and
experiments. I think relating it more to the real world is always very
helpful.
8: Yes, it is what I expected because I knew other education
majors who took it. I tried to take it last year but it did not work out
so I waited to take it this year and very happy I did.
lecture preflight 11
1: through the magnetic field
2: magnets thru copper wire
3: can you explain the earth's tilt?
4: yes.
5: labs
6: nothing.
7: yes
8: yes its a great and a fun class
lecture preflight 11
1: Since there is a north end on the magnet, it spins because
there is an electric current going through the wires and batteries.
2: That those little circle magnets are hard to pull a part!
3: Why are gas prices so high? I know part of the reason is due
to the war, but isn't there anything the government can do to lower
them? They are outrageous!
4: Yes they are useful. If I were to teach science at an
elementary/middle school level, I would bring in the different objects
and use them for experiments. I wouldn't improve anything on them
although having pieces of paper that tell us different things to use the
object for could be useful.
5: Lab because it was hands on experiments. I never took a
physics course so simplifying everything and working in lab really
helped me grasp certain ideas.
6: Nothing. I enjoy the lecture as well because I love all the
experiments Professor Selen performs. They are really neat!
7: Yes it is useful. I wouldn't change anything. The professor
goes over some questions from the lab, does cool experiments, and does a
great job with student participation.
8: Yeah. I heard it was a lot of fun - and it was!
lecture preflight 11
1: At first, the wire is an electromagnet, and the wire is
touching the paperclips. Then when the wire no longer touches the paper
clips it loses its magentic ability and is turned to point horizontal.
As it spins, it loses magentic force and is propelled around until it is
back at the starting point where it is a magnet again. The process is
repeated and it continues to spin.
2: That the geographic north pole is actually the magnetic south
pole.
3: How does an MRI work?
4: Yes they are.
5: How to explain things in a way that makes sense of something
more complicated.
6: I feel as though time could be used better.
7: It was more cool than anything else.
8: Yes, only because i had heard from a friend what it was like.
lecture preflight 11
1: The electromagnetic force only works on half the wire so it
turns it half way and then the motor continues to trun without any power
when the unshaved part of the wire is touching the paperclip.
2: That I can make my own wire with a battery.
3: Are magnetic forces the thing that professionals use when they
are manufacturing motors.
4: They are useful. Maybe the wire could be a litle more stiff so
it is easier to balance.
5: Seeing how physics works.
6: Wednesday classes I guess
7: Basing homework questions off of concepts mentioned in
lecture.
8: It is, people who have taken it have told me what it is like.
lecture preflight 11
1: The magnetic fields pushed the north and south sides of the
wire continuously making it spi.
2: I learned that the way magnets are made are by taking iron and
rubbing it against a bigger magnet which will make it have the same
magnetic field.
3: What exactly do magnets do to the back of credit cards that
makes them no longer work?
4: They are very useful, I'm glad we get to keep them. I guess
the only way they could be improved is to get better quality items (the
compass for example), but I understand that there's a budget so that may
not be possible.
5: The teaching aspect of it, I feel that the professor
approaches it differently knowing that the class is made up of mostly
el. ed majors.
6: Sometimes the random question because it was hard for me to
come up with one every week! But I liked hearing other people's
questions... so I guess it could be an option only to ask one if you
have one.
7: I do find it very useful because the professor shows us more
in depth experiments than the ones that we do in class which helps us
understand the concepts better.
8: The only thing that is different about it is that I thought we
would have tests on the content that we're learning, but I like just
having the homework assignments because they really help and its not us
cramming information that doesnt make sense the night before a test.
lecture preflight 11
1: The leads turned and spinned until the leads touched once
again. They tried to line up in the magnetic field, pushes and pulls is
the after effect of this.
2: That north and south flip when the current direction is
changed.
3: Are all magnetic fields the same for all magnets?
4: Yes, I beleive that the materials are great I don t beleive
that they can be improved.
5: The most useful aspect are the materials that we get to keep
because we will be able to use them in our own classrooms.
6: Labs can run more smoothly there was too much down time.
7: The experiments were great but I think the time was too late
in the day and maybe for future classes you should take attendence
sparatically or offer extra credit at lecture so that attendance will be
greater,
8: I really had no expectations about the class but I found the
class to be both interesting and intriguing as a result I will refer
people to this class, I already have.!
lecture preflight 11
1: The motor works because the coil switches from being a magnet
and not being a magnet. This allows the coil to spin because the current
through the coil is not constant. It is important to strip the wire so
that the current does not flow constantly, otherwise it would not move.
2: I learned that you can use a battery to create a magnet.
3: How does an electric blanket work?
4: I think that the materials from this class will prove very
useful. It is better than simply having a materials list, because we can
use each item as a reference.
5: I think that most useful aspect was in the lab. We were able
to discuss as a class why certain things worked the way they did. I
remember my physics class in high school as being very confusing,
because we were expected to work as small groups to gather the same
kinds of finding we had in class. My teacher was not very helpful and I
think discussing things as a class makes sure that everyone understands
it, not just certain groups.
6: I think the least useful aspect was not understanding what
will be on the final quiz. I go to lecture and take notes every week,
but I don't know what of the information will be on the final quiz. I
think that going over the class requirements from the website and
describing things in more detail in class would be very beneficial.
7: I think that the lecture was useful, but it was sad that no
one went up and had the static electricity lift up their hair. I think
that you scared people off a little bit when you said it only hurts a
little.
8: I signed up for the class because of a recommendation from my
counselor. I was very intimidated by physics in high school, and I
didn't see how this class could be any fun. I think that the moment I
stepped foot in the first lecture, I realized that this class would be
fun. You have a great attitude about everything and explain things in
such a simple way that EVEN I understand!
lecture preflight 11
1: The motor worked in lab because the coil, copper wire, was
attracted to the magnet. Mainly, the motor works because the magnet
switches from being a magnet to not being a magnet so the electric
attraction is happening continuously.
2: I learned that the north pole of the earth is close to the
magnetic south pole and vica versa.
3: Can coils work to heat electric blankets?
4: The materials are useful because it will allow me to remember
the experiments that we did. I could go back to our labs and re-try the
activities that we completed.
5: Completing the hands-on experiments in lab.
6: The timing could be worked out better. I think some labs could
have used more time and guidance; where as others could have been cut a
lot shorter.
7: I think the lecture is useful, I like witnessing all of the
experiments and being able to apply them to what we learned in the lab
previously that week.
8: It is what I expected it to be. I have learned a lot and have
had several positive experiences while being a student in this class.
lecture preflight 11
1: because we only stripped the insulating stuff from one side of
the coil, we were able to attach the + & - parts from the battery to the
paperclips creating a DC. With the magnet below, the current traveling
through the coil forced it to rotate.
2: I didn't learn this because i knew it from before, but i still
think that it is interesting that what we call the north pole is really
the magnetic south.
3: how do the engines in cars run?
4: yes. although i have not used any of them right now, i can
imagine that in the future they will be.
5: learning how to teach kids complex subjects with simple
experiments
6: it was all good, although sometimes we spend a little too long
going over the questions that were due for the week
7: i thought it was more entertaining than anything. it's fun
watching you get up there and do all of these complex experiments. its
nice to know what the real scientists in the world are doing, and that
we learned how very simple things can be applied to very complex
experiments that they do.
8: yes. i didn't really hear too much except that we get a goodie
box full of things that would help us teach and that we work on lesson
plans.
lecture preflight 11
1: The ends of the wire loop that are scrapped off completes a
current and thus will move. However, when the loop is flipping it
contacts the wire that is not scrapped off. Stripping the insulation
from just the top half of the wire creates the loop to continue to keep
spinning.
2: Running a current through a wire creates a magnet.
3: none.
4: Yes. I really like the idea of keeping the materials that we
did experiments on.
5: Everything we did, can be affectively used in the future.
6: none.
7: It was useful when if I was confused on the homework
questions.
8: I didnt know what to expect.
lecture preflight 11
1: When you attach the ends of the coiled wires to the wires
attached to the battery, the wire becomes polarized like a magnet. The
wire moves because you have only scraped the insulation off one half of
the wire.
2: How a motor works!
3: After flowers bloom and are then destroyed by random snow, are
they dead for the whole year?
4: Yes, I think they are useful.
5: Recovering topics that I haven't seen since junior year of
high school, and in as non-confusing a way as possible.
6: I'm not really sure... I thought the class was fun, and I
definitely learned a lot.
7: For the most part... I think it was good that we went over
some of the confusing homework questions and the fun demo's were good
motivation to come.
8: I'm not really sure what I expected from it... I guess maybe I
thought we would be more focused on how to teach things, and not
necessarily learning them for ourselves... but I think this approach was
way better and more fun.
lecture preflight 11
1: Our motor did not actually run but from what i leanred from
other people's whose did work is that the process of stipping the
insulation from justt he top half acts as a conductor for the current.
This was the key to making it spin.Also, the actual spinning is due to
the repelling of the magnet and the copper wire.
2: I think it is crazy that those strong magnets can offset a
digital watch, camera, or cell phone!
3: How do people make bullet proof glass?
4: yeah they are very useful and so is allowing us to the take
the lab worksheets home...we have a collection of the experiments we did
and the materials we used!
5: The labs. It is hands on and we get to take the materials home
with us.
6: I think the 3 hours spent in lab....it can get alittle long if
they last the whole time.
7: Yes! you are a great teacher!
8: Yes...i had friends who took this class that had told me about
it and my advisor said it made physics very fun and thats what you did
with it.
lecture preflight 11
1: a current is only induced half the time since only half the
wire covering was shaved off. when the current is induced, it creates a
magnetic field that repels from the magnets underneath. this causes the
coil to spin to the attractive side, but then the current is cut and
instead of stopping, it flips back over to the repellent side. then the
process repeats itself.
2: the north pole of earth is actually a magnetic south pole
3: what happens when the earth's magnetic poles switch and there
is, for a time, no magnetic field.
4: I think they are great. My mom teaches a 4th grade class and i
showed her many of the experiments in order to teach her students.
5: getting to keep stuff from lab
6: the online assignments need to be made a bit tougher. they are
so easy that it seems like we just get the very basic summary of things
and never learn the more interesting part.
7: honestly, i didnt go
8: yes, i loved this class and had lots of fun. if you are
looking for people, i would love to TA this class sometime
lecture preflight 11
1: The current magnetizes the coil, so when it is placed near a
strong magnet it spins.
2: That the north pole is actually magnetic south.
3: What are tears made up of?
4: Yes, but it would be good if I was able to separate them into
compartments and remember the purpose for each of them with the labs
that accompany them.
5: Learning how to use physics in a teaching situation for
experiments for elementary age children.
6: I think the labs could have been done more efficiently. They
allowed too much time for distraction at my table and we didn't learn
the material as well as we could have without so much time to work on
our individual aspects of the experiments.
7: Yes, but the time was pretty hard to schedule for.
8: Yes, it was a great class!
lecture preflight 11
1: Since we attached a battery to the paper clips we made a
circuit. To create the motor we added a magnet and the coil of copper.
There was both a positive charge and negative charge running through the
battery (this was part of what made the copper coil flip move because
there was a magnet underneath it with one side that opposed the charge
and another side that attracted the charge). Because we scraped off only
one side of the coil, that allowed the coil to continue flipping. If all
of the coil or none of the coil was scrapped off, the coil would not
flip around like it did.
2: That the North pole is actually the south pole magnetically.
3: Why do magnets mess up tv's, watches,i-pods, etc.? Today in
class you said to put anything mechanical away...why does the magnet
hurt/ruin these objects?
4: Yes, definitely! I like how we get to keep the lab sheets too.
So if we ever want to try out these experiments again (and even try them
out on our future students) we have not only the instructions, but the
materials as well.
5: Learning the basics of physics was the most useful. I really
like how every week we had a new topic (a topic of which is usually
covered somewhat in elementary school). I had forgotten a lot of the
physics I have learned over the years. It was good to not only learn
about the fundamentals again, but actually apply them in experiments.
That way, I really don;t forget them because I actually worked hands-on
with the physics principles.
6: I really didn't enjoy the group I had in lab. They went way
too fast b/c they just wanted to leave. I had to rush through the labs,
and didn't get to fully understand all of the concepts we covered.
7: Yes, I think the Wednesday lecture is very helpful because we
go over some of the answers to the quiz questions. I know we have a time
restrictions, but I think it would be more helpful if we reviewed all of
the quiz questions or at least all of the major concepts/principles we
learned. I like watching the fun demonstrations you do every week, but I
don't fully understand them all. Maybe if there were less demonstrations
and more explanations that would help?
8: It is how I expected it to be. I heard very good reviews about
the class, and I completely agree. I am really glad I took this class. I
think it really helped prepare me for teaching science in
elementary/middle schools. I now have a really good grasp on a lot of
the physics topics we covered, and if a student ever has a question
relating to physics, hopefully I can help explain it well.
lecture preflight 11
1: The charge for the rotation came from the battery. The spin
itself was due to the magnet sitting right below the coil. The
matnetically charged coil then forced itself into a rotation away from
the magnet.
2: That the poles are not located directly at the northern most
point on the globe, but rather a bit off center.
3: Why specifically is the coil such a good conductor for
electricity?
4: Yes. I enjoy them, and they remind me of the information that
I learned from that weeks lessons.
5: The lab is the most useful and interesting part of Physics
123. I enjoy doing hands on experiments that correlate to and are a
concreate example of the ideas we discuss.
6: I enjoy all the aspects of Physics 123.
7: I find the lab section more useful. However, the lecture does
help.
8: I did not expect as much hands on experimentation in the lab.
However, I like it.
lecture preflight 11
1: When the wire is exposed to the electric current the current
flows and creates a magnetic field that tries to align with the field
created by the magnet, as the coil spins the current is cut off and it
simply continues to spin because of inertia.
2: Geographic north is magnetic south.
3: Do cucumbers have nutritional value?
4: They are fun, but not very useful for me.
5: I learned how to explain things to people who do not easily
understand them.
6: I am not going into elementary education so I will not need to
use the materials we got to keep
7: It is interested and fun, but not particularly useful for me.
8: Yes, one of my friends had already taken the class.
lecture preflight 11
1: The motor worked because we only scraped off one side of the
wire with the razor and the battery provided an alternating current
which forced the wire to keep moving in a continuous motion.
2: The north pole is actually the magnetic south pole
3: How do stars form?
4: I think the materials are very useful. They are very realistic
(cheap) and we will be able to use them in the future when we are
teachers.
5: Doing the labs and then keeping the materials so that we will
be able to recreate the activities in the future.
6: I thought the class was very useful.
7: I thought it was interesting, but the time it was offered was
not very appealing. It conflicted with several other classes that I was
trying to get into.
8: It is a lot more hands on then I had expected it to be, but
that was definitely a good surprise!
lecture preflight 11
1: Since we only took half the insulation off the wire, when the
non-insulated part is touching the electrified paper clip, it is "on",
but when the insulated part is touching it it is "off". So when we start
to spin the loop, even when it is off, the loop keeps spinning and gets
the charge everytime it is on, so it keeps spinning faster.
2: I thought it was interesting that the compass changed
according to the poles of the magnets.
3: How come even though I put my same bag of popcorn in the same
microwave for the same amount of time every time I make it, sometimes it
burns and sometimes not all of it is popped?
4: I think they are useful but not necessarily worth the
expensive lab fee we had to pay for the class.
5: I hated physics before because I didnt understand any of it,
and now I actually do! That in itself is very useful.
6: Everything seemed to be pretty useful, especially to use in a
future classroom with kids.
7: I do not think it is very useful because unless you dont
understand what happened in lab or the homework, then it is just a
repeat of the lab. And since lab is so long, it makes you not want to go
to lecture the next day to learn the same things. Lectures are
interesting though because of the experiments and such.
8: Yes it has been what I expected. I had heard that it was a fun
class and it has been!
lecture preflight 11
1: The motor works because we only stripped half of the wire
which caused it to move to the part it was attracted to. The energy from
the battery went intot he paper clips which activated the wire to send
the electricity into the circular path. It would be attracted and then
wouldnt be causing it to spin.
2: That the Earth is magnetized and the fact that magnes are
attracted to the north pole.
3: what causes static?
4: Yes, some of them are very useful but many are already used or
by the time we need them they will be dried out and unable to work with.
we were given very few and just basic stuff like bolts which are easily
accessible so there isnt a point in saving them.
5: I loved that I learned something new in every class and it was
very interesting. The fact that I was able to learn but still be able to
teach these labs to children that will be easy to understand is great.
6: maybe stop more often to explain the concept and the fact that
I wasnt able to answer the quiz questions from lab so I would guess and
get it wrong.
7: I found them interesting and I liked the experiments but I do
not think it will be useful in the future. Maybe do something that we
can apply in life.
8: It was what I expected but I ddint think it would be as
interesting.
lecture preflight 11
1: Scraping the insulator half off is creating an electrical
contact and a current is flowing. It is acting like a magnet. The
attraction of the magnet from below is causing the coil to flip, but
once it flips back over, there is no current flowing because the
insulator is touching so it is no longer a magnet. There is enough
momentum, however to keep the wire moving and the whole process repeats,
keeping the wire constantly flipping.
2: The most interesting thing was to learn that the North pole is
actually the magnetic south pole and vice versa.
3: Are there magnets in any everday objects or machines that we
wouldn't expect them to be in?
4: I think they are useful. I am not in elementary education, but
I think that for someone who was, it would be a great set of tools to
refer back to when teaching science to elementary students.
5: I've never been a hands-on learner. I learn better when
thinking about numbers and formulas. For me, this was a way to branch
out and learn in a new way. It taught me a lot.
6: I wouldn't call any part of the class the "least useful." I
think at some point in my life, all of the information I have learned in
this class will be useful.
7: I find it useful. It helps to clarify some of the confusing
concepts that we cover in lab. I'm not sure how it could be improved in
any way.
8: I think it is a lot like I expected, however some of the
concepts we've discussed are a bit more difficult for me to grasp than I
thought they would be.
lecture preflight 11
1: The motor in the lab worked because we scraped off only half
of the insulation on the wire. Therefore, when we put the magnet on the
bottom of the motor, the motor worked as a motor half the time. The
magnet kind of switched on and off, and that's why the loop was able to
spin around because it was being "pushed" half of the time.
2: I learned how to make a compass using a magnet.
3: Can you explain the Earth and the "real" north and south ends?
I didn't really get it.
4: Yes, I really liked them. Also, the container really is nice
to have. However, I don't know when I will ever use these pieces of
equipment until I start teaching-which won't be for awhile.
5: The most useful aspect is that for the most part, all of the
projects we do in lab can be transfered over to an elementary/middle
school classroom.
6: I thought that some of the labs were really long, and I got
the point of the expierements after a couple of them.
7: Yes, I liked the expieriments you did. Perhaps add more
scientific definitions so I could relate the expieriments with
definitions.
8: I thought this class would be harder, and be more at
highschool level.
lecture preflight 11
1: since we only scraped off one of the ends of the wire one side
was electrically charged. This charge/magnetic force moved the coil so
the other side (non-scraped side) was touching the paperclip, thus no
electric/magnetic flow. However due to inertia the coil kept moving in
somewhat of a circle. Then the unscraped side wanted to attract to the
magnet so it kept spinning and then inertia kicked in once again when
the unscraped side touched the paperclip. It was kind of like an on and
off switch. scraped side=on, unscraped side=off
2: how motors work
3: due all motors work the way ours did in class
4: yes. none
5: using fun/doable experiments to draw conclusions on my own. I
can then implement these same techniques in the classroom
6: ....?
7: very interesting....i think it is fine just how it is
8: i expected i would learn most of the things i learned in my
highschool physucs class while doing more elementary experiments to use
in a classroom, and i got just what i expected
lecture preflight 11
1: The motor works because half of the wire is shaved on each of
the long ends. The current flowing from the battery propels the wire
when there is an attraction between the shaved ends and the battery, and
the enertia continues its movement when there is no current flowing
(when the unshaved ends are in contact with the paper clips.)
2: The geographic North is the magnetic south.
3: Why do muscles develop lactic acid build-ups after being
worked?
4: Yes they are helpful because they can be used to remind me of
an experiment done in class that I may want to repeat for my students in
the future. I don't see any way of improving the materials.
5: I like that the lessons and experiments done in class are
logical and possible to be recreated in my classroom when I'm a science
teacher.
6: Sometimes we spend a little bit too much time on elements of a
lesson that do not deserve as much time in my opinion.
7: I do think they are useful. They teach me ways of proving
certain aspects of science, and help me come up with lesson plan ideas
for the future.
8: It is and it isn't. I was expecting the class to be very hands
on and be very interactive, but I did not think that it would be as good
of a resource for my future as it is.
lecture preflight 11
1: The current flows from the battery into the paper clips and
then through the wire and out each end. Since half of the covering is
shaved off, the current flows out of the side and attracts to the
magnet. As a result the loop rotates creating a motor.
2: The magnetic poles of the earth are the opposite of actual
north and south poles. This is what causes compasses and magnets to
point the direction they do.
3: Are cellular waves effected by magnetic fields?
4: Yes the materials are useful for my future as a teacher. There
is nothing that needs to be imporoved.
5: The most useful aspect of Physics 123 is the fun experiments
we saw in lecture. Teaching science to kids needs to be fun,
interesting, and engaging. This class gave me some exciting experiments
and demonstrations to use as a teacher.
6: The least useful aspect was some of the experiments we did in
discussion. Some of them were repetitive and just went over the same
information again.
7: I enjoy attending because the information is useful for common
knowledge. It is fun because I never know what to expect. To improve it,
you could make it pertain more to what goes on in lab.
8: Physics 123 is what I expected. I heard it was a great class
and I have enjoyed it. The labs were not difficult and the class was
laid back. It was not stressful and it was useful for my major of
elementary education.
lecture preflight 11
1: The battery allows a current to flow through the copper wire.
The paper clips complete the circuit. The shaved and unshaved wire allow
the coil to continuously move in a circular direction. The magnet
attracts the opposite side to produce an electromagnet charge in order
for the machine to work properly.
2: That the people before us, labeled North and South
incorrectly.
3: How do stoplights work?
4: Yes, but it would be nice to have some materials useful for
k-3 classrooms.
5: Ideas and teaching options for science experiments.
6: Some of the labs are a little bit extensive for younger
grades.
7: Yes, because we discuss the questions on the homework and
preflights/
8: Yes, the class met and exceeded my expectations! Thanks for
your hard work :)
lecture preflight 11
1: The coil of wire creates a magnetic field. As electricity
passes through the coil, it makes the coil move, just like on a compass.
2: The north pole is really the magnetic south pole.
3: How do camera obscuras work?
4: Yes, they are very helpful in giving us a head start for
starting science kits in our own classrooms. Perhaps we can receive some
first aide things too.
5: To actually learn how everything works, and everything is
presented in simpler terms where elementary school kids can understand.
6: Some labs are really long and some times, we get into deeper
science topics. Also, the lecture was at an odd time.
7: The lecture can be earlier on in the day.
8: It was what I expected. My adviser told me I needed no science
knowledge to enjoy this class and she was right.
lecture preflight 11
1: the current flows through the coil and creates a magnetic
field.
2: You can discharge and re-charge to fix a broken compass
3: none. you're doing great professor!
4: they are useful. maybe we can leave the box in the classroom
somewhere so it won't be such a hassle to take some materials home.
5: detailed lab instructions
6: none
7: yea. they are fine.
8: yes expected
lecture preflight 11
1: The electricity from the battery is transferred through the
wires, through the paper clip and is transferred to the copper ring. The
copper ring spins because of the differences between the shaved end and
the insulated end.
2: I did not know that the north pole is actually the Earth's
magnetic south pole?
3: Do magnets hurt computers?
4: Yes, the materials are very useful because they help us to go
over the lab and remember what we did. Also, if you ever want to turn
the lab into a demonstration, you have the supplies with you.
5: We can actually take these labs and use them in the classroom.
Also, all of the demonstrations during lecture have given me some good
ideas to take into the classroom.
6: Most of the labs moved very slowly. I don't think that 3 hours
was necessary most of the time.
7: I enjoyed the demonstrations. I really find those useful. I
like the lecture as it is.
8: It is better than I expected because we have gone over many
different activities that we can actually take into the classroom. I
have a lot of useful resources that I did not expect to have when I
first started the course.
lecture preflight 11
1: The electric current gives charge to the elevated magnet, and
since the ends of the loop pick up that current on every other
revolution, it is spun by being attracted and repelled by the magnet
mounted below. One force flips it away, the other pulls it back down.
2: Copper wires have to be insulated to be practical.
3: How do metal detectors work, and how can they be made less
expensive?
4: I think it would help to be able to keep the box in the lab,
each day adding something to it, and removing the whole kit at the end
of the year. It seems like anything I bring home never gets organized
with all the other materials.
5: The lab handouts.
6: lecture.
7: It's interesting, but not really helpful. I'd recommend taking
attendance to enforce people going.
8: It's about the level of difficulty for the material, but the
grading seems tougher, because homework counts so heavily. I've gotten
all the attendance points, but my grade might be kinda low because i
forgot to do two of the homework assignments. I think they should be
worth half credit if submitted within a week after the original due
date.
lecture preflight 11
1: the wire has one side of it scratched off so that the positive
and negative poles will go back and forth to propel the motor.
2: the first magnets were discovered by the greeks because the
cooling of the molten rock from the center of the earth was magnetized
due to the earth's magnetic field
3: i've heard that if you rode a roller coaster without a safety
belt on the huge upside down turns, you wouldn't fall out..is this true?
if so, i'm sure it depends on the speed, so what is this speed?
4: yes! they are going to be very helpful!
5: getting a general knowledge base of physics that i can apply
to everyday situations
6: probably the homework
7: Yes! it really reiterates what we learn in class!! there
really isn't much to improve because the actual experiments are the best
part and you do a ton of those.
8: same, i heard it was really fun and a positive learning
environment, and not a strenuous work load...all of these expectations
were fulfilled!!
lecture preflight 11
1: The motor works by having a current flow through the
paperclips and the ring of metal (which has been partially stripped to
create a complete circuit).
2: The fact that birds can sense the magnetic pull of the earth
and that's how they know when to fly south.
3: How do you make sticky-tack and how does it remain sticky
forever?
4: They should be very useful and helpful when I am a teacher.
The packets and supplies that we received from labs will help me with
lesson plans and also give me ideas on how to make things interesting
for elementary school students.
5: It has helped me understand simple Physics/science concepts
that I will definitely use when I am a teacher.
6: I think that the lectures were the least useful because I did
not learn very much from them.
7: Again, like I said above, the lecture was fun, but I learned
the most from our hands-on labs.
8: I had expected the labs to be like they are, but I did not
know how different the lectures would be from regular (boring!)
lectures.
lecture preflight 11
1: The north side of the magnet is attracted to the south side of
the electro-magnet. This causes the wire loop to turn and the insulator
part of the wire then is touching. The loop flips again because the
magnets switch back and forth from north to south. It would not work if
the wire was not stripped because current flows through the wire because
of the battery.
2: I had no idea what an electro-magnet was or how to make one.
This was really fun.
3: Why are weather forecasters wrong all the time? Is the weather
that hard to predict?
4: The materials are really useful and practical. I know I will
use them when I teach some day.
5: I think all the experiments and labs deal with practical
things in everyday life. This is useful information to know. It's also
really fun, too!
6: I feel like everything was useful. Maybe make the labs shorter
or change the time of the lecture to be earlier.
7: It is useful because things we did in lab are discussed in
greater detail with more examples.
8: As someone who isn't great at anything science related, I was
nervous to be in a physics class. However, I feel like I learned a lot
of useful things in this class. It didn't just deal with book science,
it dealt with important things to know about science in our daily lives.
lecture preflight 11
1: the batterey makes a magnet with the wire loop when the
scratched of side is touching and this repels from the circle magnet on
the ground when the side with the polish is touching the magnet shuts
off and flips back to the unpolished side and this repeats.
2:
3: how to the differentials in a car work?
4: yes the stopwatch is usefull and the compass is useful. they
cant be improved.
5: the everyday applications.
6: The lecture doesn't have anyting to do with our grade.
7: no, make the lecture tie into our grades somehow.
8: It was easier than I thought, but fun.
lecture preflight 11
1: Through the use of a battery and some copper wire, we were
able to create a circuit in a previous experiment. We added a magnet at
the bottom of a styrofoam base, and used paper clips to hold the wire.
Eventually, the wire begins to spin (assuming its balanced and that one
side of the insulated wire has been scraped off). As the wire spins, the
object rapidly alternates between acting as a magnet and not acting as a
magnet. This was why it was important that only one side of the wire by
scraped. If both sides were scraped or unbalanced, the circuit would
never have worked.
2: I learned how to "make a motor" using household objects.
3: How does satellite radio work?
4: I think that they will be useful for an elementary school
teacher. If there are any improvements that can be made, I would
recommend having more materials available (although I'm sure time and
money are factors).
5: I like the hands-on encounter with the experiment. Instead of
being told the answer, I feel like I am really discovering it.
6: I think that, sometimes, the labs run a little longer than
they need to be. This
7: I find Wednesday lecture to be interesting. There are some
very interesting demos displayed. I'm not sure there are many ways to
improve lectures, since the majority of the material is made based on
answers to homework and preflight questions.
8: I didn't know much about the class at all, although I'd heard
from some friends who took it that it was fun. They were right!
lecture preflight 11
1: The motor that we made in lab this week works due to the
stripping of the insulation from the top half of the wire. When this was
stripped and the battery with the leads was connected to it, it allowed
a flow for the wire circle. Then the Neodymium magnets strong opposite
tattraction due what had been created allowed the wire circle to flip
around in a circular motion.
2: Something that I learned that i hadnt realized was that the
south pole is on the north side of the earth and that the north pole is
one the south side of the earth.
3: how does flash on a camera work?
4: I think the materials are very useful for future classes we
may teach. I personally enjoyed keeping everything as a model along with
all the lab write ups.
5: The most useful aspect is the lab. This is where we can
personally test alot of the things and have a more personal connection
of seeing how they work.
6: I would say the preflights were the least useful for me
because it covered questions that we learned in class already. Sometimes
i felt like we were answering the same questions twice.
7: Lecture was great! Mats always came up with good ways of
entertaining the class with different presentations/ experiments! I
enjoyed them alot.
8: Yes it was what i expected. I had never taken physics before
so i hoped that this class would be like an introductory course to how
certain things in physics work as well as a class for us to be able to
educate others on. This is exactly what it turned out for me.
lecture preflight 11
1: The current running through the coil from the battery causes
it to be polarized. The polarization of the coil causes it to be
attracted and then repelled by the magnet bellow it so it flips around
continuously.
2: I learned that the geographic north pole is actually the south
pole of the earth, which is why north polarized magnets are attracted to
it, and the same goes for the geographic south pole being the north pole
of the earth.
3: Why is the earth magnitized?
4: They were all pretty useful, especially the stop watch,
graduated cylinder and thermometer. The only thing that could be
improved would be the compasses because they did not work that well.
5: The most useful aspect is the labs that we do are for the most
part activities we could use in a elementary science class.
6: Sometimes in lab we are give complex and detailed explanations
that sometimes just make it more difficult than it needs to be.
7: Yes, because it made the concepts covered more clear and
provided real-life applications. It could be improved only probably be
more student participation in the activities that occur during it.
8: It is pretty much what I expected in both what we did in lab
and what was discussed in lecture.
lecture preflight 11
1: It is like a switch. Since only one half of a side of the wire
was stripped, it would turn on when the wire was one way (say up) and
off when the wire was another way (say down). That kept it going in a
circle.
2: How to make a motor.
3: Why do people get dizzy in long hallways with lots of designs
like in the tunnels under the 6 pack?
4: They would be helpful if I was going to be a science
teacher...this class is great for ideas on projects. However, I am a
music major, and probably will never use this...unless I'm babysitting
and want to show the kids a sweet experiment.
5: It was a science credit I could understand and enjoyed taking.
6: Lots of time was wasted in lab waiting for people to finish
their projects when our group had it done for 5-10 minutes already.
7: It was more entertaining and education than useful. Many
people don't go because attendance isn't taken and there is no knowledge
that we will be tested over later to make us have to come.
8: It is a lot easier than I thought it would be, which I like!
I'm scared of science, but not so much after this course!
lecture preflight 11
1: The wire connected to the battery forms a circuit. The magnet
underneath the wire repels it and sends it spinning. On the other side
with the insulation on the wire, it's just starts to hang.
2: The magnetic North is actually the South Pole, and the
magnetic South is actually the North Pole.
3: How does music go into the ears of a listener?
4: Yes, but I think for another physics experiment, I need a
stronger computer.
5: Mostly the conducting of heat and the review of the states of
matter.
6: I don't find magnetics particularly useful, but they were fun
to learn about anyways.
7: I enjoyed them because they were informal and also
interesting. They made it a very enjoyable class.
8: I thought it would be harder and not apply to my major
(elementary education). In reality, the experiments and the way we
learned the material could be used for my future teaching career.
lecture preflight 11
1: The loop that we made out of wire will turn right above the
magnet. After hooking the two wires from the battery up to the two
supports and giving it a little spin to get it going, it begins to turn.
The battery runs on a D/C current, so as the wire turns the electricity
goes on and off. Stripping the insulation from just the top half of the
lead was the key to getting this motor to spin because only when it hit
the one side did it make a connection that allowed it to spin.
2: Magnetism and electricity are directly related and rely on
each other to work.
3: Why do some batteries lose life quicker than others? Does the
size matter (AAA, AA, etc.)?
4: They are very useful if you are going to teach science in your
future classroom. I know that funds are probably not very large for your
class, but some of the materials were somewhat cheap and broke
easily/did not work for a very long time after lab was over.
5: I think the fact that it is so hands-on. I learned so much
from this class just "by doing". I think that is the key to really
learning something anyways. If you do it yourself and don't just think
about what doing it would be like in theory, you gain a much better
understanding of the material.
6: Lecture could possibly have been every other week?? Sometimes
it seemed a bit long and unnecessary. The experiments were always really
cool, but sometimes the attendance was so low I didn't know how
beneficial it really was to come.
7: See my answer for #6 :)
8: It was very different! I think for me, the word "physics"
brought with it a scary connotation, but this class taught me that many
of the concepts were things that I have dealt with before in my everyday
life and they weren't as hard as I thought they were going to be.
lecture preflight 11
1:
2: how to make an electromagnet.
3: do iguanas swim?
4: not really- nobody is going to keep a kit of cheap materials
to run a future science experiment, in order to run it for a class
you're going to have to purchase multiple sets regardless, one more
won't break anyone's budget.
5: hands on experience is the best way to learn.
6: 3 hours for a lab. it could easily be condensed into an hour,
just to make sure everyone knows the concepts- if U of I students take 3
hours to grasp elementary education concepts we have a problem.
7: I'd suggest making it into a lecture on current developments
in physics: bullet trains, etc- or connections from the most basic
elements of physics to modern applications.
8: pretty much what I expected.
lecture preflight 11
1: The battery attached to the paperclips attached to the wire
coil created the circuit of electicity. Then the magnets placed below
the coil created a magnetic field causing the coil to spin.
2: I learned that that the North Pole is actually located in
Canada.
3: Will the stars always remain in the same constellations?
4: Yes, the materials I kept from class are very useful because
they are materials that we actually used during our labs. If I wanted to
teach a particular lab to a class, I could try the lab again using the
same materials, just to review it before teaching it. I can't think of
any way the materials can be improved.
5: I thought the most useful aspect of Physics 123 was actually
performing the labs that I could use in the classroom.
6: I thought the least useful aspect of Physics 123 were the
Preflights. However, I did like being able to ask one science question
that popped into my head during the week.
7: I found the Wednesday lecture/discussion to be somewhat
useful. It was usesful because the homework questions were further
explained in the lecture. If I got a question wrong, I could see and
learn what the correct answer should have been. For the most part,
however, I just found the Wednesday lecture/discussion to be
interesting. It was really cool to be able to see how certain things
work, like a TV or a hot air balloon. I think it could be improved by
having a few more volunteers from the audience participate in the
different experiments, or by having Professor Selen explain to us how we
could have volunteers participate in the experiment if we ever wanted to
use the same experiment in the classroom.
8: Physics 123 was actually pretty much what I expected it would
be before I set foot in class. I had heard very good things about the
course, and was not let down. It was a very hands-on experience that
allowed me to learn and understand the material in a fun way. It was
also a very useful course for me because I now see that different
science aspects can be taught in engaging ways. I liked having the
actual lesson actitivies printed out, and being able to keep materials
from the labs. Of all the courses I have taken so far at the University,
Physics 123 is my favorite!
lecture preflight 11
1: As the electricity flows from the battery, it is interrupted
by the insulation on half of the wire so the wire flips to keep the
electricity flowing. The magnet creates a magnetic field that is
perpendicular to the wire and when it flips it is parallel so it
continues to flip.
2: The north pole is really a magnetic south pole.
3:
4: The materials were great because they helped illustrate the
concepts we learned in class.
5: A review of basic physics concepts.
6: nothing, it was all interesting
7: The lectures were very interesting but I think too much of the
class is based in labs.
8: It is what I expected.
lecture preflight 11
1: The motor works because the battery supplied a current to the
paper clips which then sent it to the coil. this allowed the current to
run through it and to the other side. The magnet on the bottom helped
keep the coil flipping because it attracted one side of the current and
repelled the other.
2: i learned how a compass works
3: is there a specific spot on earth with a greater magnetic
pull?
4: I think that they are really useful- but i think it would be a
good ides to provide some sort of helpful shopping hint guide so we know
where to find science materials cheap and fast when we become teachers.
5: that science can be fun and how to make it fun
6: sometimes i think that some of the labs were a little too
long, because the experiments got boring and were tiredsome.
7: i think that is very fun and entertaining but i dont take away
a lot from it...
8: I think it was much better than what I had thought it was
going to be- lots of fun!!!! I really enjoyed it! Thank You!!
lecture preflight 11
1: The motor works because by shaving away the insulation on the
copper wire, it ends of touching the paper clips which allows the
current to flow through the wire from the battery. What this does then
is that the coil begins to act like a magnet with one end being North
and the other being South. With a flip of the coil, the motor works
because it turns the magnet off and on with the other magnet on the
styrafoam disc. The motor generates enough of a push after a while to
get through the cycle of the magnets.
2: That the earth's magnetic north is not near the North pole but
its actually the opposite.
3: How are there so many different colors on different species of
fishes? Is there some type of pigment that generates the variety of
colors?
4: Yes they are. Even though i'm not an education major, I can
see how these materials would be of great assistance for future lesson
plans that the el-ed students may encounter.
5: To generate a basic understanding of physic concepts again.
Last time I took physics was in sophomore year of High School. So
getting a basic knowledge of it again 6 years later is pretty helpful.
6: Well since i'm not an education major, I guess the least
useful aspect would be teaching a lesson plan to the class. But I think
its not all that bad, because its essentially doing what we have done in
lab all semester long.
7: The wednesday discussion is not too bad. Its good because we
get to see experiments outside the lab room that are a bit more exciting
and fun to watch.
8: It is pretty much what I expected it to be. I had a couple
friends that have taken the class before so I was pretty well prepared
on what the course would include and ask from me.
lecture preflight 11
1: The copper wire has a positive charge which repels it from the
magnet below. Since the insulation is razored off on half of the wire
that touches the paper clip, it flips around but in order to keep
flipping, it needs to have contact with the paper clip.
2: I made a motor!!!!!!!!!! =)
3:
4: Yes! They're fun to play with!
5: It made physics easy. I've hated physics for as long as I can
remember and I actually enjoyed this class.
6: The lectures---I would make them mandatory to increase
attendance and participation. Though they were fun and interesting,
sometimes that wasn't enough motivation to go. (Using a clicker to sign
in would be one way to enforce this.)
7: see above
8: It was better than I thought! I had no idea science could be
this fun!!
lecture preflight 11
1: One side of the wire was scraped so that one side was magnetic
and the other was not so the magnetic side kept getting attracted to the
magnet on the bottom.
2: Making a motor from electro-magnets and a normal magnet.
3: If you want your fridge to be colder over summer without
consuming more energy how is that possible?
4: Yes they are, I don't think there is anything that needs to be
changed.
5: Puts everything in perspective when we use real objects and
examples in class.
6: I can't think of anything that is not useful.
7: Yes. I don't know of anything that could be changed.
8: Yes, I heard it would be a fun class where you will learn a
lot of cool things that you would not expect to learn anywhere else, and
that I did! Thank you!
lecture preflight 11
1: Scraping off part of the insulation on the ends of the wire
allowed for a current to travel through the wire when a batter was
attached to the paperclips that were holding the wire.
2: The North Pole of the Earth is in fact, the magnetic south
pole.
3: You said that the magnets can ruin credit cards. How does this
work, and why don't magnets ruin electronic items such as i-pods or cell
phones?
4: I already finished the el-ed program and have decided not to
go into teaching. However, if I were a sophmore and entering the el-ed
program, I believe that a lot of what we learned in Pyshics 123 and the
materials that we brought home could be beneficial for future science
projects in the CI classes.
5: Physics 123 showed how complicated physics explanations can be
broken down and easily demonstrated with common, everyday materials.
6: Nothing, I thought the class was a great introduction to
physics and also a great introduction to the education program, where
many of the classes are taught in a similar way.
7: I enjoyed the Wednesday classes. Even though attendance was
not taken, I found myself going to class because the demonstrations were
interesting. By using the clickers, the class is already interactive,
and I can not think of a way to improve the class.
8: It is was I expected it to be. I met with Kathy Ryan about
possible classes to fulfill my science needs. She had suggested that
this was a very good course for future teachers to take, and she was
right. I think this course is a good introduction and example of the
inquiry teaching approach that is praised by the college of education.
lecture preflight 11
1: Ours didn't work but my guess is that the motor works because
the magnetic force propels the motor
2: That the geographical north pole actually exists in Canada
rather than up top in the artic.
3: What elements make up the earth's atmosphere besides CO2,
Oxygen, and Nitrogen?
4: Yes they are very helpful.
5: the practice doing the experiments so that one day I can do
these experiements with my students.
6: nothing.
7: I enjoy the lecture because it involves the audience and the
experiements you do are so fun to watch.
8: I wasn't quite sure what to expect. I had a completely neutral
opinion. However, I loved every minute of every class!
lecture preflight 11
1: You make a circle with the wire, connect the ends through a
paper clip. You have a battery inside a charger, and connect those wires
to the two paper clips. then put a magnet underneath and spin the wire.
the wire will continue spinning due to the magnet underneath.
2: I learned that you can tell if a magnet is "north" or "south"
by pointing it at a compass.
3: Where does dust come from?
4: Yes, I am going to be an elementary school teacher, and I
think many of the experiements in class with be useful.
5: Having the labs that we could show elementary students.
6: Some of the labs were a bit boring b/c I felt like I would
never use it outside of class.
7: I thought the experiments were very interesting and fun to
watch, but some of them I feel would never be used by many of the
students outside of class. Maybe show more things that could be done in
a classroom setting by others.
8: I expected it to be somewhat like it was.
lecture preflight 11
1: The motor works because first of all it was a complete circut
allowing the electrical current to pass through. Because we shaved off
half of the insulator, it allowed for half of the copper to act like a
magnet to force it to turn part way, and because half was uninsulated it
helped make the full circle.
2: That the poles labled north and south on the earth do not
correlate with the magnet poles.
3: How does a printer work?
4: Yes they are. I enjoyed how we got to keep materials that we
used in lab. I dont think any improvement is needed.
5: Learning difficult concepts in simplified form in order to
pass on the information as future teachers.
6: I enjoyed it all and truly learned alot! :)
7: Yes. I really enjoyed the demonstrations that you did, as well
as getting more information on the topics we learned in lab. To improve
attendance maybe have like bonus points every once in a while, and
therefore it would encourage students to come to lecture.
8: Pretty much it is what I expected; however, I felt like I did
not completely understand the labs when I walked out the door.
lecture preflight 11
1: Magnets repel and/or attract each other and can cause movement
2: How to switch the poles of a magnet
3: Why do credit cards need magnetic strips
4: Yes, they are useful
5: How we learn about different stuff each week but in a way that
is really easy to understand
6: I cant think of one
7: Yes, I believe it is useful
8: Its different from what I expected because when I first signed
up for the class, I also signed up for a tutor, but the material is
presented in a way that isn't as confusing as I expected a U of I
physics course to be
lecture preflight 11
1: the electric current flows through the paper clips to the
wire, creating a magnetic field that eventually, when done correctly,
causes the spool of wire to turn due to the magnetic field
2: i can create a motor
3: how do airplanes stay in flight?
4: yes-- very useful and i do not think they need improvement.. i
was pleasantly surprised with their quality to begin with
5: i think the final project will be the most useful; for most of
us, it is our first chance to create a lesson plan and put it into
action
6: nothing-- everything is great and well planned
7: yes- it helps with learning everyday things that i would have
never thought could be explained with such simplicity
8: it was actually a lot easier-- i am HORRIBLE at anything
science related, and it didn't matter.. this was a great class
lecture preflight 11
1: The electric current was able to pass through the paper clips
to the wire because we stripped the insulation off of it to complete the
circuit. The wire spins because the magnet repels it at a constant rate,
which keeps it moving.
2: I learned that birds have an inate sense of the Earth's
magnetic field which tells them when to fly South or North! And that it
was researched here!
3: We were sticking the magnets on our hands so that one magnet
was on top and the other was on our palm. Could these magnets affect
anything on the inside of your body? Like how if you have a pace maker
you cant go through a metal detector...
4: Yes they will be useful. I don't know how it could be improved
because we each get a set of the materials to use for ourselves in demos
in our classrooms and you gave us a container for everything. There
isn't much more you can do!
5: Being able to do the experiments and discuss why things work
is helpful for my future in my own classroom.
6: The least useful aspect is some of the activities that are
repetitive, making me and my group lose interest, which leads to us not
paying attention, which leads to us not learning anything.
7: Yes! I went to every lecture and loved all of them! The
experiments tied in with the concepts is engaging and keeps me coming
every week. I think making the lecture mandatory would get more students
there, because people blow it off as "unimportant" when there isn't a
required attendance...but I think they are completely missing out on a
lot of interesting information.
8: Yes it is what I expected. When I spoke to students from
previous years, they told me what to expect. And I was excited when I
finally got into it after trying for the past 2 years!
lecture preflight 11
1: a current is formed by connecting wires to the battery and
then to the paperclips. the paperclips are touching the coil, which we
scraped parts of the sides off. the magnet that is placed beneath the
coil repels the coil as the scraped off side touches the paperclips..and
the coil continues to repel and therefore spin.
2: the north pole is actually at the south pole!
3: why is it so cold in april
4: yep!
5: actually being able to do so many different experiments
ourselves
6: all i would say is that sometimes in lab it seems to drag on
and we're given too much time for certain experiments so we end up just
sitting around.. but other than that everything was good!
7: yes
8: i thought it would be really boring and dreadful like
basically all of my other science classes... but it was very interesting
and fun!
lecture preflight 11
1: Since the ends of the wire have half of the varnish scraped
off and an electric current runs through the paper clips touching the
ends, the wire has a current through it, which makes it magnetic. The
magnet underneath makes the wire coil spin, and so it does a half spin
from the electric current and then falls back down with its own
momentum.
2: I did not know that you could make a non-magnetic object
magnetic by hooking it up to a battery.
3: How does a battery generate electricity?
4: I think they are useful because they are all things I can use
easily for examples in my own classroom in the future.
5: I think that the way everything in class and labs is explained
is useful because I did not understand many of the topics we've covered
before this class and now they seem easy to understand.
6: Probably some of the questions in lecture because they seem
repetitive.
7: It was sometimes useful because it would further explain
concepts from the lab, but sometimes it just seemed really repetitive.
8: It was basically what I expected because I talked to someone
who had taken the class so they told me what it was like.
lecture preflight 11
1: The motor works by the battery creating a current in the wires
that goes to coil of wire. With the magnets underneath the loop, the
loop kept switching directions and also turned into magnets. It would
stop to get current and continue spinning.
2: I learned that when you scrape insulation off, you have to do
exactly half or the motor will not run.
3: How does the magnetic field vary in other parts of the earth?
4: Yes, they are useful. They can be more audience adaptive
though.
5: I feel learning the basics of physics with this class will
help me remember in the future.
6: I thought some lab experiments were not useful at times.
7: Yes, i do because it prepares me for lab and Mats is a great
professor.
8: Yes, this is what I expected. I expected to grasp the basic
concept and that is what happened.
lecture preflight 11
1: The current through the battery is transformed to the ends of
the coil. The magnet creates a magnetic field between the coil and the
magnet and the current allows the coil to circle opposing the field.
2: I thought it was interesting to move a magnet sitting on the
table by using a magnet under the table. It was amazing how strong the
force must be to go through the wood.
3: How exactly is a magnet created?
4: I believe that the materials we keep are not that useful. If
the labs could be modified so each lab had a mini project which created
some end product, it would be useful to take that home.
5: The most useful aspect would be to better understand the basic
theories in physics. These basics are important when teaching kids since
most of the questions they ask are usually the questions that we have
discussed in class.
6: The labs should be cut down to two hours because it just seems
to be a waste of time to be there for three hours when the labs do not
even take that long.
7: Yes it is definately useful and adresses many new topics that
are not discussed in the lab section. It can be improved by encouraging
participation through mandatory clicker points.
8: It is definately what I expected it to be and more. I really
enjoyed taking this class and have recommended it to all my friends.
lecture preflight 11
1:
2: I learned that the battery and wire contraption could be made
into a magnetic item. I thought this was really interesting and was
something that i had not ever done before.
3:
4: I think it would be really helpful if we had a "teachers
guide" and were given more information so we could directly take the
stuff from physics to our own classrooms in the future.
5: I think that the practicality of the experiments we did were
the most useful. Many of these projects were ones that I have done in
the past in my own science classrooms growing up and it is a good
reminder of how we can teach them when we are the teacher.
6:
7: I think the lecture was good because it allowed us to see more
examples of experiments relating to what we learned in lab during the
week. These were experiments allowed us to be presented with the ideas
in a different manner, sometimes which made more sense than in lab.
8: I expected physics 123 to be more geared towards college
students, but I found it really helpful and practical that we learned
how to deal with specific things that we will need to know as future
teachers. I really enjoyed the class and know that I will actually get
to use something I learned in the future.
lecture preflight 11
1: sends a current through the wires and since electicity and
magnets are related the current causes the wires to flip around from the
pull of the magnet
2: that when the magnet is on the string and you walk around with
it the north side always faces the north side of the room
3: how do i pods work?
4: yes
5: the hands on activities during lab, that each person was able
to participate
6: the lab is toooooo long.
7: yes it is useful but not for what we do in lab. attendance
should be taken or some extra credit to get people to go.
8: it is what i expected. it is very interesting and makes
physics understandable
lecture preflight 11
1: The electric current runs through the wire half the time, when
the side that was carved touches the paper clip as the electric current
runs through it. As the current runs through the loop, the magnet pulls
the wire horizontal, which then makes the current go back through the
wire, which makes the motor.
2: The coil gets hotter and hotter the more batteries you hook up
to it.
3: If the north pole is actually the south magnetic pole, why
didn't we just call south north and north south?
4: Yes they are for elementary education students who plan to
teach similar things to their students in 3rd grade. As long as people
keep the labs and everything, there is not too much room for
improvement.
5: It helped remind of the simple rules of physics. Even though I
am not an education student, it was nice to see all the different ways
we teach our young children about physics.
6: There isn't enough quantitative analysis to go along with the
qualitative analysis. No math to back up all the concepts, so can not
answer any rather specific question.
7: Yes, I enjoy being shown other examples of labs that help show
physics principles we discussed in labs. It could be improved by doing
something that enforces students to come, because often students don't
show up to lecture.
8: Yes it is what I expected. However, I knew someone that took
it last semester so I knew exactly what to expect, but I did enjoy it
more than I would have expected.
lecture preflight 11
1: We worked with magnets.
2: Magnets have a very strong force on the direction of
compasses.
3: What do chromosomes do??
4: Not really. If we had to do projects at home, then yes they
would be helpful. However, I have never needed to take them out of the
box.
5: Our TA Joel. He explains things very well. Also, seeing the
experiments in lecture helps me understand the overall importance of the
week.
6: The materials we bring home. They are useful in class but not
after that.
7: Yes, however some times I feel like we aren't learning
anything that is related to the theme for the week.
8: Yes. I only heard good things about this class and I would
definetately/already have recommended it to my friends!!
lecture preflight 11
1: The motor works because there is insulation on one half of the
wire and no insulation on the other half. The field lines are on
opposite ends and they do not like that, so the magnet gives a kick
which is the movement caused by the electricity turning on on the side
where there is no insulation. The electricity turns off on the side with
insulation. This causes the motor to work.
2: I learned that the geographic North pole is like the magnetic
South pole and vice versa.
3: How hot is the sun?
4: I think that they are useful because they can be used in my
classroom someday. I may not have enough for every student, but I will
know what various types of science materials look like now.
5: The most useful aspect is actually doing the experiments. I
think thats important so when I teach I know the experiments work and I
will have more insight.
6: The least useful aspect is not turning in our labs. I think we
should have to turn in our labs so students take the class more
seriously.
7: You should give points for coming to lecture. You probably
have one of the most interesting courses for teachers and I think it is
beneficial and fun for students to go to!
8: It is different. I really like the variety of experiments that
we do. I also like that we go over the experiments and why they work.
lecture preflight 11
1: The motor works because since we shaved part of the plastic
covering off the wire, it will conduct a current. If the coil of wire
were perfectly balanced the magnet underneath it would help give it a
push when it comes to the opposite side of the magnet. This and the
current would make it keep spinning for a long period of time.
2: I learned that you magnitize a coil of wire by attaching it to
a current which allows it to have a current.
3: If there is always a North and a South Pole, when they make
magnets what do they do differently so that the South and the North pole
of the magnet are different.
4: Yes, the materials are very useful. There is really nothing
that needs improvement. The materials simply make us understand the
concepts better especially if we forget a fact and go to the materials
and try it again.
5: I think that the most useful thing about Physics 123 is that
apart from showing you how things work, it also showed us that
experiments and science in general does not need to be complicated. In
fact, you can explain and make it fun so that students can enjoy
themselves while learning, which in the long run will help them retain
the information in a much easier manner.
6: I think that everything we learned and performed in class was
very useful.
7: Yes, I find the lecture very useful especially when I don't
really understand a concept.I especially enjoy the lecture demonstations
in which you show us how physics is applied in things we perform in our
everyday lives.
8: It is much different than I expected. I taught this class was
going to be very challenging and I wouldn't understand any of the
concepts. However, it was very fun and the professor made things flow
really easily. I understood all of the concepts and I felt like I knew
"why" many times.
lecture preflight 11
1: We made motors using wire, paper clips, a battery, and
magnets. The motor worked because we only shaved off half the rubber on
the wire, which caused it to rotate consistently.
2: I learned about how the North and South poles on the Earth
correspond to the North and South magnetic poles.
3: Is the ocean blue the same way the sky is blue?
4: Yes I think they are because I will always be able to look
back on them during my teaching career. I wouldn't change any part of
that.
5: The labs, because not only did we get a packet every week to
keep but we got the materials to go with it. I think those will both
prove very useful later in my career.
6: I know I personally attended lecture every week, but it seemed
like some people felt they didn't need to as the numbers decreased every
week. I think that there should be some sort of lecture activity that we
turn in for points so that more students would come to lecture. I know
it's like bribing people with points, but I think the experiments and
activites we do in lecture are both interesting and entertaining, and
all students should see them.
7: I definitely found it useful because it tied everything that
we learned in lab together with fun demonstrations. I think Prof. Selen
has such a love for physics, and it definitely shows during lecture. I
don't think it needs to be improved, except for what I said in number 6.
8: From what I had heard from friends, it was pretty much what I
expected. Except I think I am taking away a lot more from the class than
I thought I would, and it has really made me want to teach physics in a
fun and interesting way just as Prof. Selen does.
lecture preflight 11
1: The motor was able to work because the charges from the
batteries provided enough current to flip the loop. Stripping the
insulation from just the top half of the leads allowed the motor to spin
because when the charges touch they become like a magnet and the
non-insulated side of the leads has no current so it keeps spinning.
2: I learned that magnets can be strong enough to affect your
credit cards and mechanical watches.
3: Why do batteries die??
4: Yes, they are very useful because when we are teachers we can
use these materials. They do not need to be improved.
5: The experiments were the most useful aspect of Physics 123
because I learned a great deal of basic knowledge which I did not have
before.
6: The least useful aspect of Physics 123
7: Yes I really enjoyed lectures because they were fun and
interesting.
8: It is different because I have never taken such a fun and
interesting class before.
lecture preflight 11
1: The bare wire allows for current to flow through while the
insulated half of the wire allows for the wire to act as a magnet and
stay stationary. With the current running through (due to the battery
hook up) it has a tendency to rotate the suspended wire (that is above a
magnet) when the bare wire is touching the paperclips. When the
insulated part is then turned to it is touching hte paper clips, the
wire acts as a magnet and is attracted to the magnet underneath so it
flips again. This process continues.
2: You can attract strong magnets through solid materials (ie-
hands, tables, etc.).
3: How is tempered glass designed to break safely?
4: They are useful because we can use them in future classrooms.
I just wish we were given some sort of resource on where to find them.
5: The activities that we participate in that I can bring into my
future classrooms.
6: I honestly cannot think of anything.
7: It is more interesting than useful I would say. I think maybe
if you posted all the questions that people pose and the answers to the
questions (via experiment write ups).
8: No, our advisors were pretty clear on what to expect in your
classroom.
lecture preflight 11
1: The coil rotates because one part of the wire has no
insulation so as the wire rotates it goes from being a magnet to not
being a magnet and rotates because of the in attraction and repulsion to
the magnet below the coil.
2: The magnetic south pole is actually what is marked as the
north pole.
3: How do electric blankets work??
4: Yes, although I'm not sure I'll be using the materials, if
anything I'd be using the labs themselves.
5: Learning physics on a somewhat elementary level gave me
perspective on how my students will view concepts they do not
understand.
6: I think some of the labs could have been a bit shorter and
more to the point, while some needed more time (i.e. the egg breaking
lab).
7: Yes, I loved seeing the experiments although I would have
liked ironed out concepts being talked about and being able to take
notes (thats how we work in college).
8: Yes, I was told it was a class in which you were able to do
elementary type experiments to explain basic physics principles. I was
also told it was a lot of fun, which it was :)!
lecture preflight 11
1: The round up metal keeps on spinning and the poles flip.
2: Field lines always point towards the south and away from
north.
3: Why do people twitch in their sleep?
4: I feel like they are useful in understanding the lab but I
don't think they are very useful to me now.
5: I feel that the most useful part of Physics 123 is relearning
the basic concepts of physics. It was helpful to relearn some of the
topics because I feel like I have forgotten a lot of that information
since the last time I studied it.
6: Sometimes I felt that the lab was unnecessarily long and also
that the lecture was not very helpful at times.
7: Yes and no. I feel like some weeks when I didn't really
understand the lab, the lecture did help. Other weeks I felt that the
discussion was unnecessary and I feel iike I understood the ideas from
lab well. It could be improved by maybe going more in depth to the
concepts rather than just discussing the homework.
8: I was very nervous about this class because I don't know very
much about physics. Much to my surprise, I have been able to understand
all of the concepts that we have learned about in lab.

1: I shaved off half of the wire, because that is what made it
rotate, because it wants to line up the magnetic fields correctly. If
the whole thing was shaved then it would just sit there. If it wasn't
shaved at all, no current would move through it.
2: I learned that the North Pole has a south charge.
3: How does the internet work?
4: Yes, they are cheap items that can be found in Wal-Mart, so
they are easily accessible.
5: I learned how to explain physics in afun way that kids can
understand.
6: Sometimes I felt like we wasted time in lab, but overall it
was real fun.
7: Yes, it was always exciting to see what would happen next.
8: It is better than I expected, it was funner than I thought it
would be.
lecture preflight 11
1: We shaved off half of the insulating layer around each end of
the wire. If we didn't shave off the coating, there would be no
current-and therefore no magnetic field. If we had shaved the
entirelayer off, it would have a ocnstant current and not move. So, we
shaved half of the coating so that the coil rotates must constantly
rotate to line up its magnetic field. A battery provided the current,
because currents cause magnetic fields.
2: I learned that the Earth's south/north poles are different
than their magnetic south/north poles.
3: What is a black hole?
4: very useful
5: going over why things happen
6: Going through the lab activities so slowly that by the time we
get to the explanation part I've forgotten what I did!
7: Lecture is always fun and interesting, but more people should
come!
8: I heard from many people that it was a fun/interesting class,
and it has definitely been that so far.
