Day 154: Colliding Bouncy Balls & Isostacy

AP Physics: Colliding Bouncy Balls

Students continued to work on their final projects. One student worked on colliding pairs of bouncy balls together at different speeds to see how bouncing changes against an elastic surface instead of a hard one.

Earth Science: Isostacy

We didn’t actually use the word isostacy today, but students floated blocks of different kinds of wood in a bucket of water and measured the ratio of the block above the water to below the water. I’d love to plan ahead better and get a better mix of blocks with several with the same density, but different volumes. I was able to get around that by having them stack two identical blocks to see the ratio stays the same.
