What is air

What is air?
What causes air to move it is wind


Experiment: Air Exists


Equipment: Container filled with H2o
                    A Jar
                    Paper Towel


Predict: will the paper stay dry? Yes


Why? Because it it is like a air bubble it will keeps out the water. That would be the same with the jar.


Observe: Someone pushes down a jar with a paper towel in the jar and then pulls it up.


Explain: When the Jar is going into the water a cushion of air forms at the top of the Jar which is facing down to keep the paper towel dry.
