Mad Science Lesson---Dry Ice

Here's what the students wrote about this lesson:

Dry is so cold it burns you.  There was gas called carbon dioxide.  Gas is air.  He talked about gas.  My favorite part was shen he went around and got smoke on us!  Carl put a balloon on a science bottle.  It blew up.  In Mad Science we learned about carbon dioxide. (a.k.a. smoke)  It is like the stuff in soda.  A gas is the oxygen we breathe.  Dry ice is so cold.  It is colder than your refrigerator.At first if you pick up dry ice, it will feel hot. I learned we should never touch dry ice with our bare hands.  There was a little bottle called Peter the Penguin because it has like a little beak.  Smoke came out of the beak. When I came to the rug we were like chemicals. First we were squished. The we got a little squished. Finally we weren't squished. We got to learn about solids, gasses and liquids.  We learned when you put dry ice in a big bucket, it makes a lot of fog.  The particles in solids are very close.  Liquids are spread apart.  Air is very spread apart.  Dry ice is carbon dioxide.  Regular ice turns into a liquid, then a  gas.  Dry ice doesn't.  It just turns into a gas.  One kind of gas is air.  When we were close together, it's called a solid.  When we were a little apart, it is called a liquid. Science is very dangerous.  Franny K. Stein is a Mad Scientist, too!  I learned that gas is very easy to walk through.  I loved it. It was fun!
