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***
