Was just talking to a friend about childhood science experiments the other day. She did one to answer the question of what factors influence the ripening of a banana. Where do bananas ripen faster? If left on the counter in the kitchen vs. in a brown paper bag vs. in the 'fridge vs. wrapped in cellophane vs. in a cool and dark pantry, etc.

My son (admittedly in 1st grade) did one on Hotwheels, inspired by the question of what makes one Hotwheels car faster than another? So we kept it simple and measured distance traveled instead of actually timing cars. He taped coins onto cars and noted that the heavier the car, the farther it traveled.
