COLLISIONS
Investigation 1
You are going to roll the toy car down each of the five slopes (5 being the steepest). Before each run predict how far you think it will push the sponge. After each run measure how far the sponge has been pushed. Say how close your prediction was.

Slope	Prediction (cm)	Distance sponge moved (cm)	Difference (cm)
