Ramp Classic

What is an easy force and motion laboratory idea to do in class?

I want my children more interested! They are already building egg of a parachute, dropping toy cars down a ramp at different heights to notice the change in speed, and the ball drops from different heights. The classic already been made. Even if one of the ideas you have is classic, may not have heard of it, so please tell me anyway! Thanks About a level 9th grade, but higher and lower will also be useful. I'm kind of despair.
