We've been on a quest to prove that air exists. It's tricky because you can't really see it or touch it which is how we prove other things exist. So we have completed several experiments to try and prove that air: takes up space, has mass, has pressure, has volume, and that it can be compressed.
Our experiments have been wet and messy but that's totally cool because often messy learning is the best learning.
Here we were submerging a paper ball attached to the bottom of a beaker. When we pulled it out, the ball of paper was dry!!! What does that prove?
Here a bottle covered by a balloon is placed in very hot water. Slowly the balloon inflates! What does that prove?
Here we pull plungers out of syringes while covering the hole. One girl has her ears covered. Hmmmm? What's about to happen?
