With some carts lying around in one of the science storage rooms, students agreed that using these carts could be wayyyyy better at controlling variables than dropping objects to collide from various heights and at various speeds. After colliding these carts with different materials on a track, we saw a lot of patterns:
1. There always seemed to be an energy transfer--the cart that was going faster became slower when it hit the other cart and the cart that was moving slower became faster the moment it collided with something else.
2. There was always some kind of bounce-back.
Students still felt that the collisions were moving too fast for them to really see if there was any deforming/misshaping happening. So Mr. Carmalt and Mrs. Brinza made some slow-mo videos of each of the controlled investigations we saw.
It was so cool to see that in some of the slow-mo videos, some of the solids deformed. This got us thinking...does every material deform somewhat?
