- How does keyless entry on a car work and how do they only work for one specific car? It has to do with infrared, I think, but how do they program something like this?
- Body temperature: How come I can be FREEZING in the same room as my best friend who is HOT?
- I remember making ice cream one time in Chemistry. I can't remember the point of that experiment though. We used cream and ice and flavoring and shook it all up. What might have been the lesson/concept we were learning?

- How did the liquid nitrogen form a liquid inside the balloon?
- Why is it that snow trucks fill the streets with salt to make snow melt? What is it about the salt that makes the snow melt?
- Does light have weight? Does light make sound?
- How does microwave oatmeal work? Or any oatmeal, for that matter... I thought about this after the cornstarch experiment in lab this week. Oatmeal gets that same gooey quality but it depends on heat as well.

- Sometimes when people get cancer and end up losing their hair, it will grow back a different color or type (exp. curly when it was straight). Why is this?
- How does a microwave heat up food?
- I heard that if you give a strawberry to a baby before it is three months old, the baby with become alergic to strawberries...is this true?
- I wanted to know how liquid nitrogen is formed and how it is able to convert things into solid just by touching them. I would like to know how exactly the liquid is formed, produced into a container that is malleable to use in experiments.
- If you dipped a towel into liquid nitrogen and dropped it would it shatter?
- How is dry ice formed?
- Why, in lab, when the hollow rubber ball was thrown against the wall it shattered, but the solid rubber ball when bounced acted more like a pool ball and did not break but was just very hard? I would think that it would've at least broken in half since the hollow ball completely shattered.
- what causes static?
- I would really like to see what happens when different things are put into the microwave :).
- What is the approximate weight of an atom??

- Does liquid nitrogen burn skin or does it freeze it?
- How exactly does salt melt snow?
- Last Summer, I went to Sanibel Island for a couple of weeks. One night, I was out walking on the beach, and the water was playing weird tricks. It looked and felt like I was walking on top of water. Why was that?

- How did they come up with the term "moles" in chemistry?
- How many gallons of water are in the ocean?
- What makes some snow like powder and other snow "snowman making snow"?
- If you are swimming in an indoor pool (where the temperature is relatively cool) and the weather outside is also VERY cold why does steam seem to rise out of the water?
- Why does glass feel so much like a solid if its particles are moving like a liquid?
- What is a good way to explain to students gravity on earth compared to gravity on the moon?
- How does the salt used during a snowstorm melt ice?
- Is dry air or wet air colder?
- How many gallons of water does the ocean have?
- how much does a proton weight?
- i know that light is the fastest thing in the world, what comes up second or third?
- With the recent snow fall. I was wondering why some snow fall is fluffy where you can't make any snowballs, but then why at other times some snowfall is the kind where you can make tighter snowballs?
- How does medicine make you feel better?
- Why is the sky blue?
- What would happen if I were driving at the speed of light and then turned my headlights on?
- How many gallons of salt water are in the ocean?
- Why does firewood make a popping noise when it burns?
- What causes static?
- why can you not break a diatomic molecule like H2 into atoms?
- How do airplanes stay in the sky?
- Why does liquid nitrogen bubble like it's boiling when it's so cold?
- Why is water bigger when you freeze it?
- why can you feel the bass from a speaker
- The power in my room died a few days ago, so I was wondering-what is the maximum amount of volts a circuit can handle before the fuse will blow?
- Why does an atom when reflected on a flat surface shoot out at the same angle?
- From the lab, I did not understand the corn starch experiment. Why was the solid corn-starch turning into liquid if you put it on your finger?
- How are fruits such as watermelon bred to be seedless?
- How does nitrogen turn rubber balls so hard that they shatter when thrown against the wall and then take the properties of rubber again?
- Why does it have to be so cold here?
- Why do high pitched sounds break glass?
- What goes on in shampoos that cause them to make hair shiny?
- Well, since we were talking about atoms in lab today I was wondering how different the composition of a chewy cookie and a regular crunchy cookie would be. Is there a difference in the atom composition because one is softer than the other?

- why does sweat sometimes smell and other times it doesn't?
- What is a mole?
