Preflight

lecture preflight 03
1: Granite on the fireplace and the metal chair legs.
2: The fabric chair seat and wood trim felt much warmer then the items listed above.
3: The metal and granite did not absorb the coolness of the room as much as the wood or cloth. Cloth and wood are good insulators while the metal would be a good conductor.
4: Your hands give off heat and the mittens act as an isolator to trap the heat given off.
5: I learned what a wind chill is.
6: How does the light bulb work exactly? I know the bulb is a vacuum and there is a filament inside but I still don't get it.

lecture preflight 03
1: Metal shelves, door handle, coffee tumbler
2: Pillow, dresser, pencil
3: The heat capacity of the various items in my room are different. The metal shelves, door handle and coffee tumbler all have a much lower heat capactity than my pillow, dresser and pencil. The lower the heat capacity, the harder it is for the object to store heat.
4: Well, first of all, mittens are much warmer than wearing gloves. However, the reason that they both keep your hands reasonably warmer in the wintertime is because they are made to keep the heat radiating from your body inside the vicinity of the glove/mitten. The heat cannot escape into the cold, winter air, so it just floats around inside your glove/mitten, keeping your hands nice and toasty.
5: I really was intrigued by the explanation of wind-chill. It made so much sense to me!
6: Static electricity: why does it happen so often in the winter time? My hair is always a static mess during this season!

lecture preflight 03
1: The metal items, like the doorknob, cans of pop in the case, and my hair straightener were colder than items that weren't metal.
2: Some of the warmer items were the wooden desk and chairs, my cotton sheets, and plastic things.
3: This has to do with heat capacity. Metal items have a lower heat capacity than the plastic ones. The plastic and wood are also poor conductors.
4: The material of the gloves or mittens trap in the body heat that your body is releasing. That way it feels warm still. It you were to just measure the temperature without anything inside it, it would be room temperature.
5: I learned that water has a high heat capacity. I am from Chicago and always wondered why people say that its always "cooler by the lake." Now I know it has to do with the lake absorbing the heat from the air. I also learned what wind chill was!
6: I've heard that your body responds better to short "cat naps" verses long two of three hour naps. Is this true? Are you really more refreshed after sleeping for like 25 minutes?

lecture preflight 03
1: Glass drink bottle, plastic lotion container
2: wooden desk, cotton clothes
3: because the colder things are better conductors of heat, so they require less amount of cold to feel cold
4: they prevent your body heat from escaping
5: i thought learning about swap heating was interesting and talking about why you cant cool down a room with a refrigerator
6: what is a snow flake, and how does it get its pattern???

lecture preflight 03
1: bed sheets, brick walls, floor, mirror, desk
2: carpet, clothes in a drawer
3: different materials absorbs heat differently
4: the gloves or mittens traps heat from your body temperature
5: lab was cancelled this week
6: no question

lecture preflight 03
1: Metal feels colder than wood. Wood feels colder than cloth.
2: Plastic feels warmer than wood.
3: The molecules are more tightly packed together so that there's less movement.
4: Gloves trap in your body heat.
5: I didn't have lab this week.
6: How does salt melt ice?

lecture preflight 03
1: my metal lamp, my cell phone, my mirror
2: my wooden desk, my bed
3: Certain materials absorb the temperature more than others giving the illusion that they are warmer or colder.
4: The material that gloves are made of do not absorb the cold protecting your hands and keeping them warm.
5: That university of Illinois does have snow days.
6: I hear this storm started in Texas as rain. As storms move across the US how can the escalate to different levels of precipitation.

lecture preflight 03
1: Ceramic bowl, metal trunk, glass
2: Couch, magazines, blankets
3: Metal and glass are a better conductor of heat but also lose it faster.
4: They lose the heat energy first, saving your hands for later.
5: I learned that it's nice not to have to walk all the way over to Loomis in the snow...
6: Why does my cell phone battery die so much faster if I don't have good service?

lecture preflight 03
1: metal, tin foil, pictures,
2: Nothing really felt warmer.
3: They might feel cooler because although they are the same temperature as the room, they are cooler than our body temperature, so they feel cool to our touch.
4: Wearing gloves in winter keeps your hands warm by acting as really bad conductors of heat. They hold in the heat that comes from your body and keeps it from escaping.
5: I thought it was really interesting how wind does not affect temperature. It simply makes us feel colder by blowing our body heat away from us.
6: How do airplanes fly?

lecture preflight 03
1: the wall, desk, things made of metal
2: cloth, paper
3: metallic objects generally have non-porous surfaces and may actually be colder than other objects. Objects like cloth and paper absorb the heat of your fingers better than metal objects. They have porous surfaces that retain heat, like when you have a blanket around you, it will hold your heat.
4: The gloves trap your body heat in your fingers and also provide a protective layer from the outside air. Since outside air can't come in, the air and heat comes from your body.
5: Heat always flows from the hotter object to the colder object
6: Can you cut an onion without crying? why does it make you tear?

lecture preflight 03
1: Scissors, necklace chain, silver picture frame, glass candle holder
2: Sweatshirt, pillow, pencil, fan, alarm clock
3: The items that felt colder are made of materials that have better heat capacities, like metal.
4: They trap the warmth radiating from your body and keep it close to you.
5: Wind-chill is caused by the wind blowing the little gas insulator that surrounds our skin
6: None of my windows have condensation on them, but when I went to a store yesterday, the front door was completely frosted over. Whats so different between my glass door and their glass door?

lecture preflight 03
1: My desk felt colder than my cell phone. My printer felt colder than my backpack,
2: My bed sheets felt warmer than my television set. My table felt warmer than my water bottle.
3: The heat capacity of an object usually depends on the mass or weight of the given objects.
4: Yes in the winter the air outside is cold, but it is obviously warm inside of the gloves. So when the cold air comes in contact with the warmth of the gloves, it goes towards the warmth.
5: Temperature depends on how fast the atoms are moving.
6: How much of a burning issue is global warming really? What are the risks? Will I see them in my lifetime?

lecture preflight 03
1: My metal nightstand, my keys, my metal picture frame, T.V. screen, and my metal trash can felt colder. (note: my apartment is rather cold)
2: My wooden desk, my plastic folders, my remote control, and my printer, and my wooden chair felt warmer.
3: Some items absorb heat better than others. Even the slightest change can significantly affect the temperature of certain items.
4: The heat that your body gives off is insulated and trapped inside the gloves or mittens to keep your hands warm.
5: I learned what exactly wind chill means and how it works. I found it extremely interesting that we have a layer of heat that is very near our skin that keeps us warm when we enter cold weather; I had no idea that when the wind blows, it blows this heat away making us colder than it actually is outside.
6: Are houses in Alaska and other cold places around the world built with different materials than normal houses to cater to the cold weather and to insulate heat better?

lecture preflight 03
1: metal objects such as keys or my desk lamp. Things made out of plastic also felt colder. The tile on the floor feels cold.
2: Things made out of cloth like my tote bag and blankets. Paper. The rug always feel warmer then the tile.
3: Some things might feel colder than other things because of the material that they are made out of.
4: Wearing gloves in the winters keeps your hands warm because they are insulation and provide and extra layer of protection against the cold.
5: SNOW DAY!!!
6: How are we able to see a rainbow?

lecture preflight 03
1: The plastic wheels of my chair, the wooden table in the middle of the room.
2: The couch, my computer.
3: Because of what they are made of and how those things feel towards your skin.
4: Wearing gloves or mittens in the winter keeps the air that is coming off of your body inside the glove so around your hand, keeping it warm. Also, the cold air on the outside is not hitting your hands.
5: I did not have lab this week.
6: Is global warming causing this blizzard?

lecture preflight 03
1: filing cabinet and metal chair leg
2: wodden door
3: some are better insulator and others are conductors
4: it traps the heat inside
5: wind chills
6: how do fans work relative to thermodynamics?

lecture preflight 03
1: the top of my spiral notebooks and textbooks felt colder than my desk/chair.
2: My clothes felt warmer than my desk/chair
3: Probably due to the material it is made out of. Since the clothes is on my body and I'm a little cold, the shirt/pants feels very warm to me. With my textbooks/notebooks, the plastic covers and metal spirals feel colder due to it being out of plastic.
4: Since they are made out of cotton/wool, once they are put on, they keep the warm air trapped inside which then keep my hands nice and toasty!
5: I learned that it takes a lot of snow to finally get a snow day at the University of Illinois!
6: Even though my windows are shut and the heat is on, my fingers/toes are freezing! Why is that?

lecture preflight 03
1: A glass and A plastic drawer
2: the wooden desk and the comforter
3: I think it is because of the materials the objects are made out of. Some are easier to feel the temperature of. Also, some might hold temperature better than others.
4: Gloves help to keep the heat from your hands from escaping into the air.
5: Heat or energy cannot be created or destroyed, so when something is cold it just removes the heat to some other place.
6: If heat cannot be created or destroyed, how does an oven get hot?

lecture preflight 03
1: Glass
2: Table, door, binder
3: The temperature of your hand may be different.
4: It insulates your hand, and keeps the heat from escaping.
5: When ice melts it doesnt really change the temperature of the water.
6: How is wind chill calculated?

lecture preflight 03
1: The chair feels colder than the desk.
2: The tv screen is warmer than the bed rail.
3: The reason why items differ in temperature is due to the materials that they are made of.
4: Gloves keeps your hands warm because they keep material close to your skin and they also keep your fingers close together.
5: I didn t have lab this week
6: What is the proper way to read a thermometer?

lecture preflight 03
1: metal lampstand, top of desk, computer monitor
2: notebook, empty coffee cup, speaker
3: Some things have higher heat capacities than others.
4: The mittens help the heat energy already in your body to remain there instead of going out into the cold world.
5: Heat energy flows from the hot thing to the cold thing.
6: What's up with global warming? We are having a really cold winter--is global warming real?

lecture preflight 03
1: My metal picture frame, my lamp (not on), my chair, and my metal glasses case, my jacket.
2: my door, my printer and my folder.
3: I think that the reason some things feel colder is that they are good conductors of heat. If my hand is warmer than something metal, then the metal would absorb the energy released from my hand. Other things that are not good conductors of energy might take longer to equalize the temperature, so at first touch nothing happens.
4: Wearing gloves or mittens prevents the heat/energy from escaping. It serves as an insulator to keep the energy near your hands.
5: I thought it was very interesting to learn about how windchill works. I had no idea that there was a warm layer of air near your skin that keeps you warm when there isn't wind. It makes a lot of sense!
6: What is the stuff inside of the lightbulb that lights up?

lecture preflight 03
1: can of pop, camera, perfume bottle, rings
2: lap top, blanket, chair
3: Some things may feel colder than other things because the atoms of those objects are not moving as quickly as the atoms moving in the warmer objects.
4: These are ways to prevent heat from flowing out.
5: The heat capacity of an object depends on the mass of the object.
6: How does febreze remove the smell of a room?

lecture preflight 03
1: tile, glass, metal
2: carpet, blankets, sheets, and pillows, plastic
3: Some materials are better conductors of heat than others. Heat could possibly be like sound. Sheets abd rugs absorb sound, while it bounces off tile and metal. Perhaps heat is similar, and the softer materials absorb the heat while the harder ones do not do so as easily.
4: the material is insolation. It's like my mom telling me to keep the front door closed in the winter, because we don't need to pay to heat the outside. The gloves are like a door to our body. They keep out heat in, and it does not easily escape to the outside.
5: if it's a small heat capacity the temp changes a lot. If it's a large heat capacity it hardly changes
6: Can it ever be too cold to snow?

lecture preflight 03
1: The metal part of my desk, the floor, the binding of my notebook
2: the wooden part of my desk, the carpet, blankets
3: If they are good conductors of heat or not
4: Wearing gloves keeps your hands warm by being a good conductor of heat. This means that it warms your hands, but keeps the heat in and preventing the wind from coming into your gloves.
5: I thought that the temperature inside the hat would be warmer at the end of the class period but it was the same temperature.
6:

lecture preflight 03
1: My desk top, the pretend-wood shelves on my bookcase, the metal end of my scissors
2: my plastic lotion bottle, the plastic end of the scissors, a post-it note
3: Some things may feel colder than others due to how they conduct heat. For instance, in regard to the rods submerged in liquid nitrogen, the metal ones were all freezing yet the wooden rod and plastic rod felt pretty normal.
4: Even though the gloves and mittens don't physically create heat, the help to trap in the heat that your hands create (thus, your body heat is contained close to your skin and not allowed to escape)
5: Even though the glove/mitten thing seems like common sense now that I know it, i was suprised that the temperature did not increase at all inside the hats. I thought for sure that they were able to create heat, though I guess it makes sense now because its like when you climb under all the covers to go to bed and they are cold at first, but gradually become warm.
6: Is there a temperature that snow will not fall if it is below? It seems like once it gets REALLY cold, it never snows.

lecture preflight 03
1: My candle, my hair spray can, my mirror.
2: My speakers, my printer, my pillows
3: One reason is because the speakers and printer are running. They are working and gain heat while doing that.
4: They are an extra layer of protection so they protect against wind and coldness.
5: That we didn't have it! =)
6: Why doesn't beer freeze!?

lecture preflight 03
1: Electrical Outlets and windows
2: any electronics that were turned on
3: if something is wet, it can feel colder
4: the heat from your hands doesnt to directly into the wind, but heats the gloves. some of the heat from the gloves go back into your hand and some goes into the air.
5: didnt have lab this week
6: why did isolated spots get so much more snow than others, such as new york

lecture preflight 03
1: Ceramic mug, metal rod, metal scissors
2: wood desk, cloth, light that is on, computer that is running
3: Some materials will always feel colder because they conduct heat differently. Glass and metal tend to feel colder than wood or plasic because of what they are made up of.
4: When you wear mittens or gloves, the heat stays more 'trapped' within your gloves and your hands stay warmer. You are not losing as much body heat in this way.
5: We didn't have lab...
6: How does one huge snowstorm come at once? why are some years so much drier (like last year, we hardly got any snow!)than others?

lecture preflight 03
1: The top of my desk lamp is made of metal, and it feels colder than other items in my room.
2: My plastic water bottle that had been sitting out all day, a newspaper, my mousepad.
3: They are made of different materials- some of which conduct heat better than others.
4: They trap the heat and block it from escaping your body.
5: How to find the temperature of objects that one would normally think is not possible. For example, our group had no idea how to find the temperature of the metal washer until you guys told us to place them in cold water and determine the temperature that way.
6: Say it snows during the night...why is it colder during the day before the snow comes, and warmer the day after the snow falls?

lecture preflight 03
1: Metal, glass, glasses
2: Wood, lip balm
3: They can release their heat faster than the other objects
4: the air next to your hands heats up and stays near to your hands so it keeps them warm
5:
6: Why did people think the moon was made of cheese?

lecture preflight 03
1: metal chair leg, hair brush, cell phone, lamp legs, perfume bottle
2: desk itself, chair cushion, textbook
3: Some of the object felt colder because they are good conductors of heat, this means that things flow easily through these objects which makes the temperature change more readily and sometimes it will feel different than the actual temperature of the room.
4: Wearing gloves or mittens will help keep your hands warm because they prevent heat from flowing. Since it can't flow, it stays inside of the glove, keeping your hands warmer than the outside air.
5: I thought the most interesting thing from lab this week was when the liquid nitrogen was poured on the ground and it turned into ball-like pieces.
6: In newer cars sometimes there is an option of having a type of automatic start where you never have to enter a key into the ignition, it simply has to be in the car. How does that work?

lecture preflight 03
1: Digital camera, unlit candle, bed frame (metal), 3 hole punch
2: Computer, wood desk, paper, alarm clock
3: Some materials may be able to absorb heat differently than others because they are different conductors of heat. The metal objects I felt seemed to be much cooler than the paper or plastic objects, perhaps because paper, wood, and plastic can absorb heat easier than metal.
4: When you are wearing gloves or mittens, it is the air that you are trapping around your fingers that keeps your hands warm, since they are not being exposed to the cold air and you have trapped the warm air that is circulating within the glove or mitten.
5: Playing in the snow is really fun!
6: Why do icicles form as they do?

lecture preflight 03
1: metal lacrosse stick, metal chair leg, keys, camera
2: wooden cabinet, wooden door, shot glass, perfume bottle, plastic part of stapler
3: Some things are poor conductors of heat which means it doesn't allow heat to flow through it as easily as other things do.
4: It is because your body is producing heat and the gloves don't allow the cold air to come in. They act as a barrier and prevent the heat from flowing outward or by not allowing the cold air to enter through the gloves.
5: The fact that the objects temperature is the measurement on how fast the atoms are moving which is why our hand submerged in warm water felt cold when we put it in luke warm water.
6: What makes the difference between packing snow and powder snow?

lecture preflight 03
1: Metal door knob, metal lamp, plastic desk chair arms
2: Wood door, wood desk, desk chair fabric
3: Most of the things that I listed that felt colder would seem to be better conductors of heat, and the others seem to be insulators. Maybe the insulators retain more heat on their surface, making them feel warmer, whereas the heat from the conductors is transfered into the air, making the conductor a little cooler. Also, these things might not have a very high capacity for heat.
4: When you put on gloves or mittens in the winter, it serves as a barrier to keep the warmth from your body from escaping. When the heat does escape, it remains enclosed inside the golve close to your hands. If you weren't wearing any gloves, the warm air escaping your body could just be blown away by the wind.
5: Heat transfers from warm to cold (air conditioners are warm on the outside)
6: What causes hiccups?

lecture preflight 03
1: My highlighter My eye glasses brush
2: My hair tie banana shirt
3: Perhaps because the items that felt warmer were softer.
4: Wearing gloves or mittens keeps your hands warm because these items act as insulators. They do not allow the heat/energy escape from your hands into the air. Instead, that heat/energy is trapped inside the mittens and gloves.
5: I learned that if you stick a thermometer inside a glove or hat for two hours, the temperature does not go up.
6: How do batteries work?

lecture preflight 03
1: My plastic radio next to the window, my refrigerator door handle made of metal.
2: My television remote, my plastic chair.
3: My radio is cold because it is by the window and the warm air is escaping outside. The refrigerator door handle is made of metal and is near the cold inside of the refrigerator so I assume that the energy from the inside of the refrigerator escapes when the door opens and is absorbed by the metal handle.
4: It provides a barrier so the body heat that the hands produce does not escape into the air.
5: That ice cools your water more when it melts than when it's a solid ice cube.
6: What is the most efficient or effective way to reverse the global warming problem?

lecture preflight 03
1: My metal keys feel colder than my desk. My lotion feels colder than the air.
2: My phone feels warmer than my desk.
3: Different materials conduct heat differently, so the temperatures feel warmer or colder when compared to another object.
4: It traps in the heat from your body and blocks out the cold air. As a result,
5: We did not have lab. I learned that show can be a wonderful thing :)
6: How does the weather go from being warm to being a blizzard within a few hours?

lecture preflight 03
1: glass mirror, metal
2: carpet, plastic
3: I had a hard time differentiating temperatures, but I think it was because my apartment is sooo cold! The carpet and plastic seem to be warmer because of insulation, whereas the mirror and metal felt colder due to the coldness of the room. However, it was slightly confusing if you base the results off of conductors?!
4: The gloves and mittens in the winter keep your hands warm by insulating and keeping the heat from your body inside that area. The heat is trapped inside the gloves from your body, but the gloves/mittens do not add warmth on their own.
5: I really liked the explanation of the driving and toll booth analogy for changing states of matter; solid, liquid, gas.
6: Why do we see exhaust in the winter?!

lecture preflight 03
1: clock, bed frame, television, chair, fan, garbage can
2: carpet, speakers, pillow, blanket, hangers, keyboard
3: Since temperature is measured by how fast atoms are moving in an object, the objects that are a little colder have atoms that are moving slower than warmer objects. Heat always flows from hot to cold, so the heat from the colder things flowed somewhere else.
4: Wearing gloves don't make your hands warmer. Gloves just keep the heat from escaping your already warm hands.
5: When you turn on the air conditioner, the air outside actually gets a little hotter.
6: When a first grader asks you where babies come from, how do you answer them?

lecture preflight 03
1: metal frame of my bed
2: fleece jacket
3: if an object is more reactive to heat energy, it will lose and gain more rapidly.
4: it traps the heat that wants to escape from your hand.
5: not available. SNOW DAY
6: Does snow and ice have different temperature?

lecture preflight 03
1: My ice cube is colder than my alarm clock. My window is colder than my dresser. My metal glasses are colder than my plastic medicine bottle.
2: My plastic glass is warmer than my ceramic crab. My stuffed butterfly is warmer than the surface of my refrigerator. My computer is warmer than my metal lamp.
3: Our mind tricks us and makes us think that some things are cooler than others. We generally associate cloth as warm and metal as cool in the winter, so maybe these ideas affect the way we feel things.
4: Gloves or mittens help retain the heat that escapes from our hands as well as providing an extra layer that blocks the exposure to the cold air.
5: I learned that this is the first snow day this university has had in 28 years :)
6: How does condensation appear in your room when it is cold outside and warm inside.

lecture preflight 03
1: Metal, glass
2: wool, plastic, carpet
3: some materials take more of the heat from one's hand, making them feel colder. Like metal.
4: It keeps the air warmed by your hands close to your hands. No wind.
5: Hats and gloves don't radiate warmth, they protect it.
6: How do space pens write?

lecture preflight 03
1: mirror speakers empty coffee mug
2: desk book
3: certain materials are apt to feeling colder even if at the same temperature.
4: they trap the heat that is constantly being released from your body.
5: HOW TO BUILD A GOOD SNOWMAN!!!
6: Why does a car window fog up when it's cold outside?

lecture preflight 03
1: My desktopm, dvd case and febreze air spray
2: My mouse pad, my paper cup, and my shirt
3: I think that it depends on the type of material the object is made out of.
4: I think that fabric absorbs the heat from your hands and retains it. So it is like a heat trap.
5: My lab was cancelled today.
6: Why is snow white?

lecture preflight 03
1: metal door knob, metal light, brick walls, window
2: wooden desk, wooden door, carpet
3: Different compositions like wood and metal feel different at the same temperature. The molecules act differently and therefore, metal feels colder than wood. The metal absorbs more heat than the door, so it is colder.
4: Our bodies create heat and this heat escapes. Gloves act as insulators and keep this heat inside our bodies.
5: I learned that putting a thermometer in a glove or hat doesn't necessarily warm it up. Energy is needed to create heat so the temperature will rise.
6: If the universe is expanding, but the universe is everything, where is it going?

lecture preflight 03
1: My television, My door handle, picture frames, my desktop
2: my bed, my clothes, my towels
3: Some things are better heat conductors so they take away more heat from your body making you feel cold.
4: The fabric keeps the heat emitted from your hands from leaving.
5: no lab...
6: Why is grass green?

lecture preflight 03
1: The wooden door in my room felt a little colder then expected. I also have some plastic office materials that felt a cold.
2: The metal chair in my room felt a little warmer than expected. This leads me to believe that metal conducts heat better than other objects. This is why it is good to use metal pots and pans when cooking.
3: Some objects conduct heat better than others. Metal conducts heat better than other materials such as plastic and wood.
4: I believe that the material that the gloves or mittens are made of is better at holding out the cold. The hands are extremities and are very difficult to keep warm.
5: I learned that does not conduct heat, but rather acts as an insulator.
6: How do you throw a curveball?

lecture preflight 03
1: The microwave,television and my metal picture frame.
2: My bottle of handsanitizer, my desk, cereal box, box of chips, plastic cup and my pen.
3: I think that the depending on the material that they are made of makes them feel like they are colder. For example metal will seem colder than plastic because in reality when putting them in cold the metal will probably get colder faster.
4: Wearing gloves in the winter allows you to stay warm because its is a an extra layer of warmth. With this layer you do not have direct contact with the cold.
5: Unfortunately we did not have labe this week do to the horrible weather conditions.
6: How do leaves change colors?

lecture preflight 03
1: My metal key and ceramic mug than other things in my room.
2: The wooden desk, printer, and backpack in my room felt warmer than others.
3: Some things feel colder than other things because of the different type of materials they are made of makes then seem colder than other things.
4: Wearing gloves or mittens in the winter keeps your hands warm because wool or cotton fabric feels warmer than other materials, so they keep your hands warm from stimulation of touching a warmer object.
5: I learned that more than 5 inches of snow and high winds causes the University to cancel classes and lab.
6: What causes extreme high winds?

lecture preflight 03
1: metal trash can, mirror, wheel of chair
2: laptop, clothes, alarm clock
3: some are better conductors of heat than others. Some are better at keeping heat OUT than others.
4: In the winter, your hands are at body tempature when you are inside. When you put your gloves on and go outside, the gloves are used to keep the temperature of your hands the same, or close to the same, as what they were when they were inside. They do not warm your hands up, but retain the heat of your hands.
5: hats, without a head, do nothing for warmth!
6: is it really the speed at which snow is moving that makes it hurt when it hits your face?

lecture preflight 03
1: the rim of my mirror, my keys, my lamp stand, my drawer handles
2: my pillow, my desk, the clothes in my closet, my carpet, my blanket
3: They are conductors of heat, meaning they let heat through instead of insulating it.
4: Air is a good insulator and keeps the air around your hands from blowing away.
5: I learned that when an object is exposed to wind, it is still the same temperature as before the wind blew on it.
6: How do regular (non-window) air conditioners work?

lecture preflight 03
1: My metal color pencil box, spoon, cell phone
2: Plastic glass, pencils
3: Most of the metal things don't seem to conduct heat as well.
4: Keeps your body heat closer to your body.
5: We didn't have lab this week, but last week, the whole concept of cornstarch with water, transforming from liquid to solid was very intriguing.
6: How do you capture fragrance and make it into perfume?

lecture preflight 03
1: The top of my desk, the keyboard on my laptop,and the surface of the mirror behind my desk.
2: the cushion on my futon, the coffee mug that was sitting on my desk, and the cover of my math textbook
3: Heat may not be completely absorbed as well by some objects as compared to others. For example, the cushion on my futon may have felt warmer than the surface of the mirror behind my desk because its fabric, soft texture absorbed the heat energy from the air more completely than did the flat, solid surface of the mirror.
4: The cold from the air is trapped by the fabric of the gloves, and they absorb the cold energy before your hands do, asking as a barrier.
5: No Lab :(
6: Wishing it was warmer outside... How hot is the sun??

lecture preflight 03
1: The metal objects felt the coldest, then the tile floor.
2: Wood objects felt warm.
3: Things felt colder when they conduct heat better, because room temperature is colder than body temp, so heat flows from my hand into the metal more efficiently than into wood, this increased difference in temperature potential makes them feel colder.
4: gloves and mittens insulate the air surrounding your hands so your body is able to warm this air to a comfortable temperature. Thus the air inside the gloves is much warmer than the air outside of the gloves, so the heat from your hands doesn't escape nearly as fast, and they feel warmer.

lecture preflight 03
1: Some items that felt colder than others were the door knob, a water bottle, and my cell phone.
2: Some items that felt warmer than the others included blankets, my desk, and my math book.
3: I am not positive of the answer, but this is what I think. Some things like metal feel cooler than other things like wood because metal is a better conductor of heat. Therefore, if I touch a metal object, the heat from my hand will flow away faster than does in a wood object, leaving the surface of the metal and the surface of my hand feeling cooler. The heat flows from my hand to the metal because my body temperature is warmer than the temperature of the metal.
4: Honestly, I am not really sure, but I think that gloves or mittens trap in your body heat.
5: I didn't attend lab this week.
6: How do we know about Earth's layers?

lecture preflight 03
1: my desk, the base of my lamp, my mirror
2: my bed, the carpet, my towels
3: some things extract more heat from your body so they are colder to touch
4: it keeps the heat from your hands from escaping into the air
5: blizzards are fun
6: what makes bread rise in the oven?

lecture preflight 03
1: door knob, floor, wall, metal lamp
2: my chair, desk, plastic drinking cups
3: some objects are better conductors for heat than others. Therefore good conductors allow heat to flow creating a warmer feeling.
4: it becomes an insulator and does not allow the cold air to enter- creating a warming affect through the pocket of air that surrounds the fabric and your body/body temp.
5: That even if you try to heat up a glass of ice cold water with your hands, allowing the ice to melt, the temp of the water will not change.
6: well i just got the hiccups and wondered how they work and whats the best way to get rid of them! thanks...

lecture preflight 03
1: the door knob of the wooden door, the handles on the desk, and metal chair leg of the desk chair feel colder
2: the wooden door, the top of the wooden desk and the top of the wooden dresser feel warmer
3: I think that some items absorb temperature better than others, so that's why I would think the metal items felt colder than the wooden items since we are in the winter right now.
4: gloves and mittens act as a seal to your hands. I feel like it absorbs the cold weather outside taking it longer to reach your hands.
5: Ice absorbing energy when turning into water and vice versa. I didnt know that was true. I actually thought the opposite for a while.
6: Why does snow only fall at certain temperatures. Such as why is that when it is colder outside than today's snow day, snow wouldnt fall?

lecture preflight 03
1: Metal cup, batteries, remote controls
2: Pillow, pencil
3: The material they are made up of would make them feel colder.
4: When heat escapes your hands, the mittens or gloves traps that heat in that area warming the air/area surrounding your hands.
5: Heat to cold!
6:

lecture preflight 03
1: My doorhandle felt cooler than the door and the top of my desk
2: The side of my computer monitor felt warmer than the top of my desk and my door.
3: Different items are made of different materials. Some materials have a much higher heat capacity than others. An item that has a very small heat capacity may feel warmer than another item that has a larger heat capacity.
4: They trap the heat that is leaving your body inside of the mittens, thus keeping your hands warm.
5: the temperature isndide of 2 mittens will be the same as the room's temperature.
6: Sometimes when I am driving on the expressway, and am passing a truck, I feel like my car is being pulled towards the truck. Is this my imagination? If this is happening, what is the cause of it?

lecture preflight 03
1: mirror, dresser, draw erase board
2: printer, corkboard, plastic hook rack, my bed
3: The items that I mentioned are all made from different materials. Some are made from wood, some from plastic, some from cotton, some metal, etc. Things like cotton bed sheets do not get as cold as a mirror.
4: Because they are made of cloth they keep your hands warm because they do not get as cold as other materials.
5: We had a snow day so I did not learn anything interesting in lab!!
6: Why does an ice cube melt faster in tap water than salt water?

lecture preflight 03
1: the table, my ipod, my printer
2: the bed, a book, a pencil, my dresser
3: It may depend on the material that they are made of that makes a certain object feel colder than another object. also, it could have to do with where in the room that object is. For instance, objects that are closer to the window may seem to feel colder than another object.
4: Wearing gloves in the winter keeps your hands warm because they are covered by material, and the wind chill will not be a strong against your hands.
5: Well, we did not have lab this week, but I am sure I would have learned about why things seem colder or hotter when they are in the same temperature.
6: How does gasoline make cars and other things run?

lecture preflight 03
1: door knob, candle holder, mirror, cd holder, mop handle, tape measure, hangers
2: the bed, couch, pillow, laundry basket, mouse pad
3: I think the reason some things feel colder is because the different items absorb the heat in different ways. For example, items like cloth were warmer than metal hangers or even textbooks because even though everything is at the room temperature, the heat capacity of the different objects are different.
4: I think that wearing gloves or mittens will keep your hands warm beacause the heat that your body is giving off is being absorbed into the material of the glove or mittens which doesnt escape very quickly to the outside. I also think that mittens will keep your hands warmer than gloves because your fingers are physically next to each other and the heat will bounce off eachother to keep them warmer. However, once the gloves are removed your hands will become cold because the heat is escaping rapidly and therefore your hands will become closer to the temperature of the outdoors.
5: One interesting thing I learned in the lab this week was how the temperature of hats or gloves aren't physically warmer if you were to test the temperature. It takes your body heat to cause the heat of the objects to become greater and keep your body warmer by having the gloves and hats keeping the heat in.
6: what causes static?

lecture preflight 03
1: computer, mirror, cinder block wall
2: desk, chair, paper
3: different objects are better conductors of heat than others, i.e. metal objects
4: gloves or mittens keep the wind out and create an insulation type area around the skin
5: i learned that gloves do not necessarily keep you warm, they just keep the wind out and keep the air around you warm
6: how do planes stay in flight up in the air?

lecture preflight 03
1: Metal chair back, glass table, counter top
2: Arm of the couch, television, carpet
3: The metal chair back is hard and not pourous. It does not feel as warm as the couch because the couch can absorb the heat from the room.
4: The material of the gloves absorbs the heat and puts a layer between you and the wintery winds.
5: We had a snow day for the first time in 17 years...that's interesting! :)
6: Does lightning really never strike twice in the same place?

lecture preflight 03
1: the floor, the lamp pole, metal hanger
2: clothes, desk, folders
3: Some things may feel colder because they are good conductors of heat or they may feel warm because they are poor conductors of heat.
4: The gloves or mittens keep heat from your hands inside the mittens or gloves to keep your hands and the air around your hands warm.
5: I learned about the heat capacity of objects and how they are affected by other objects. THe water would become the middle temperature of the two but like in the case of the steel and the water, the steel had a larger change in temperature.
6: Does a drop of water roll or slide?

lecture preflight 03
1: metal stand, tv, wall
2: carpet, wooden door
3: everything in the room is at room temperature, except my body temp. is higher, so when I touch something thats a better conductor of heat like metal it will feel colder because..the heat from me is being taken away faster by a metal as opposed to something like carpet?
4: the gloves keep heat that's being released from your hands from escaping
5: actually realizing that a hat does not make one or something warmer by letting off heat.. but by preventing the heat from escaping
6: why do flower petals wilt?

lecture preflight 03
1: Metal door handle, wall, lamp
2: folder, desk chair, printer
3: The things that are warmer are worse heat conductors than the things that are cool, so they always stay around the same temperature.
4: The gloves will keep the heat that is produced by your body from moving around too much, which keeps it closer to your body.
5: I learned that a hat doesn't actually increase the temperature of the air like I thought it would, it just keeps the warmer air from moving around too much.
6: When making popcorn, why do the pieces make the forms they do when they pop instead of just exploding?

lecture preflight 03
1: The leg of a chair is colder than the top of my desk. My metal curling iron was colder than my haor brush.
2: My wooden shelf was warmer than my metal towel rack. My plastic glass was warmer than my glass vase.
3: Some things feel colder because they conduct heat faster or temperature in general. Metal for example, conducts heat the best and turns cold just as fast.
4: They provide insulation. The warm material keeps the heat inside, so no heat escapes and keeps my hands warm.
5: I learned that metals are the best conductors of heat.
6: Why does glass not conduct as much heat at metals?

lecture preflight 03
1: Arms of the desk chair, desk lamp, door knob
2: Blanket, gloves, pillow
3: This is because some things are able to conduct heat better than others and therefore, retain the heat while others lose heat right away.
4: They provide some sort of insulation because wool can keep heat restored. This is why heat is trapped and your hands don't feel as cold.
5: Lab was cancelled due to the weather conditions :)
6: How does snow retain its shape and not turn into some other weird form after it is on the ground?

lecture preflight 03
1: glass container, ceramic envelope, metal bins
2: wooden desk, wooden bed
3: some things are better conductors of heat and therefore are colder, even though all the objects are sitting in the same room at the same temperature
4: Wearing gloves or mittens helps keep your hands warm because when you are outside, the heat wants to leave your body, but the mittens trap the energy of the heat inside and keep you warm.
5: I thought that it was really interesting that the experiment with the steel washers only changed the temperature of the water a little bit. I would have thought that the steel washers would have caused the temp. of the water to significantly drop.
6:

lecture preflight 03
1: metal holder for pencils and pens, scissors, cd
2: computer,desk, shelves,
3: they feel colder because of the material they are made out of. some objects are better conductors than others and hold more heat which accounts for the difference.
4: im guessing they keep the heat inside your hands when your body generated the heat it gets trapped inside the material of the gloves and warms your hands.
5: that snow days are fun!!
6: if you have a cold is it better to work out and sweat out the bug or just lay in bed?

lecture preflight 03
1: Metal chair, metal book ends, leather chair
2: Wood door, wood desk
3: You are warmer than everything, so when you touch metal it is better and conducting the heat than you so it begins to take it from your hand, making the metal feel cold.
4: It not only puts fabric on them to keep the wind from directly touching them, but also the fabric keeps the heat of your hands inside the gloves.
5: My lab was canceled.
6: Why does everyone get sick when it is this cold out?

lecture preflight 03
1: Some items that felt colder were the tops of my dressers, my calculator, a metal door knob, and my glass piggy bank.
2: Some items that felt warmer than the otehrs include paper, my cloth purse, and a marker.
3: Some things might feel colder than other things because of what they are made of. It depends on the material that the object is made of. Different materials absorb heat and energy at different rates. For example, the hard tops of my dresser were much cooler than my cloth purse. The cloth purse was able to absorb heat better and more efficiently.
4: Wearing gloves keeps your hands warm because cloth is able to absorb and retain heat. It insolates and absorbs the heat from your body.
5: I did not have lab, but I would hope that I learned about what materials absorb heat and why some materials absorb heat better than other materials.
6: How many inches of snowfall is considered a blizzard?

lecture preflight 03
1: For this assignment I touched the glass window, a metal filing cabinet, a mirror and a wooden chair. The glass window, the metal filing cabinet and the mirror were definelty colder.
2: The wooden chair was the warmest.
3: I think that the reason why some things might feel colder than other things is because some actually absorb energy while others don't absorb as much engery. This is also explained in regards to atoms. The colder an object is the slower the atoms will move, on the other hand, in warm termperatures the atoms will always move faster.
4: Wearing gloves or mittens in the winter keeps your hands warm because it allows your own body heat (coming from your hands) to be trapped within the fabric. Therefore, even though you might still be out in the cold your hands will feel warmer because of body heat.
5: One thing that caught my eye this week in lab was the explanation of why some objects get colder than others when exposed to very cold temperatures.
6: What causes lightening?

lecture preflight 03
1: My phone, a three hole puncher, the filing cabinet, the door knob.
2: My wood dresser, the desk, my bed sheets, my chair.
3: Because different objects absorb heat differently. It makes sense that the objects I felt to be colder were mostly metals, because it is harder for a metal to keep heat in, so it naturally gets colder faster than a cotton fabric for example.
4: Because the fabric of the gloves are able to trap in the heat coming off your hands.
5: Since my lab was canceled, one interesting thing I learned during the time I was supposed to have lab was that I am very glad to have a heater in my room.
6: How does a heater make hot air, and an air-conditioner make cold air?

lecture preflight 03
1: my pillow(material), night stand(plastic), zipper pull(metal),
2: the under side of my pillow and blanket, the inside of my drawer, stuffed animal
3: i am not too sure, but i think it has to do with the way that the object retains heat.
4: it keeps the heat produced from your hands from leaving.
5: when we dipped our hands in the tubs of water, i didn't realized that i knew this, but we do it all the time when we go from pool to hot tub and i thought it was really cool if make that connection! :)
6: What is going on with the weather, i am not convinced with global warming but how is it that we didn't have a white Christmas but we have a white valentine's day?

lecture preflight 03
1: My lamp (turned off) and my mirror and my drink felt cooler than my desk.
2: My computer, my desk and my shirt felt warmer than other objects.
3: The particles inside of them are moving at different speeds. For example, cloth, metal and woods are all different.
4: Gloves and mittens prevent the heat from escaping.
5: We didn't have lab this week.
6: What causes a blizzard?

lecture preflight 03
1: metal chair leg, stereo
2: glass table top, wooden door
3: Some things may feel colder because of the material they are made out of.
4: The heat that is given off by my hands is trapped inside of the gloves.
5: It is interesting that U of I actually canceled two days of class.
6: Why does oil float on water?

lecture preflight 03
1: Desk surface, tin of mints, can of pop, metal part of chair, metal lamp
2: Hairspray (in plastic bottle), plastic part of chair, paper
3: Some things may feel cooler because they are better conductors of heat, items such as the metal on my chair or a can of pop conduct heat much better tahn plastic or paper.
4: Mittens and winter hats keep body heat contained, thus keeping your hands and head warm. Mittens and hands prevent your skin and the air from trying to even the temprature out between the two and keep the body warm.
5: The way in which we learned how heat flows, with the transfer of enegry helped me to understand heat flow. Also, the idea of heat capactiy was something I did not understand before.
6: How do self-warming packets for your hands, back, etc 'create' heat from nothing?

lecture preflight 03
1: refrigerator, metal bed frame, metal lamp, carmex, doorknob, metal coat hanger, perfume bottle, metal chair, tin can, license plate
2: TV, computer, microwave, stereo, hot tub
3: All of the warm objects have electricity running through them, therefore they have a warmer temperature. Because it's cold outside and the cold objects have little to no energy, they feel colder.
4: Your hands give off heat and the mittens/gloves trap that heat in, therefore keeping your hands warm.
5: lab was canceled due to the blizzard
6: how does acupuncture work?

lecture preflight 03
1: drawer knobs, barrett, metal chair leg
2: computer, mouse pad, blanket
3: Depending on what type of material an object is made of, it reacts differently to the air, releasing and absorbing different amounts, which changes its temperature.
4: Gloves keep the wind from directly hitting your hands, and it's really close to your hang, so the body warmth keeps the heat in.
5: Canceled! But I'm sure it would have been very interesting!
6: What makes a bouncy ball bouncy?

lecture preflight 03
1: metal leg of the desk, the wall, dresser inside the closet
2: wooden desk, picture frame
3: Depending on the material an object is made of, some objects are better conductors of heat than others.
4: Gloves act as an insulator, it traps the body heat from your hands within a contained area, keeping your hands warm.
5: I hope to learn what happens when you mix two objects/liquids of different temperatures together. What is the new temperature? How long does it take for both substances to change?
6: What are black holes?
