I did my post of our Atmosphere study while on vacation and I forgot some things so I thought I would share them in a separate post.

I really liked these experiments because they helped show how air behaves.

This one was simple but really good.

You just take an empty bottle and push it under the water.

This helps kids see that their really is something in the bottle even though it looks empty, air!

This one shows how hot air rises.

You put a quarter on top of a bottle and put it in a sink filled with hot water.

The coin “magically” jumps when the hot air rises.

It was a little hard to keep the quarter on top so we switched to a half dollar but it was too heavy.

Quarters seemed to work better.

My boy crushing some ice for our next experiment.

You put the ice in a plastic bottle, put on the cap, and shake it up.

Then watch the sides of the bottle be pulled in by the cold air!

All of these worked great!

I got them all out of the book “The Usborne Book Of Science Activities Volume Two”.

Great book!
