1. If the surrounding air is pressing down on the kids with ~15 lbs on every inch of their bodies, why aren’t they being crushed?

2. How is air pressure different at sea level than higher up in the atmosphere? Draw a picture.

3. What is going on with the changes in volume with that balloon?

4. An egg is used as a model for the thickness of the atmosphere, what makes this a good model?

***From 2:00 til the end, there are instructions on how to make a barometer. Make one of these at home, measure the changes in air pressure, record your results. TWO WEEK HOMEWORK PASS AWARDED***
