This is a classroom favorite. Students will design and build racecars from milk cartons, push-up pop wheels and power them with balloons. Helps demonstrate all of Newton's Laws of Motion (inertia, a = f/m, action-reaction).
Materials needed: milk cartons, straws, push-up pop stems (or other wheels), balloons, stop watch.
Main topics: force, mass, acceleration, Newton's Laws of Motion, experimental design.
Quick, easy, and effective in demonstrating Newton's Laws of Motion. It will take
