For my experiment I'm going to reconstruct my marble maze from 4th grade. The materials ready are cardboard, straws, cotton sticks, craft sticks, cup, clay. I can change the size of the marble, length of track.

I would like to reconstruct the famous experiment that took place on the Leaning Tower of Pisa. I would use different sized objects and drop them from the top of a tower I built. I would make them have parachutes sometimes. I record how long it took them fall.
