Pushes, Pulls and Ramps

Children sort everyday actions into pushes (away from you) and pulls (toward you). With a ramp simulation and a real ramp, they find that a higher ramp sends a toy car farther, then run their first fair test: same ramp, same car, only the floor changes, and the bumpy carpet stops the car sooner than smooth wood.
