Gas pressure, loads of fun

ACT ONE: Weight a balloon then deflate the balloon. How much does air weight? (I probably need to compose a table for this one)

ACT TWO: Bring out tennis balls. Half of them are fully inflated or presurized (hard to squeeze) and half are not really pressurized (easy to squeeze). Go over a mini investigation as to "Why is gas pressure?" When they are done, draw a picture.

ACT THREE: Read pages 370-373, and take notes

ACT FOUR: Can air pressure do work? (See demonstration pg 372-373) How does this work with air bags

ACT FIVE: Have questions from end of the chapter written out for them to do.

ACT SIX: If needed, go over them if we have time.
