Terrific toys turn into a demonstration of the transfer of energy. Potential energy becomes kinetic energy as the wind-up toy walks, a popper flies into the air, and a balloon whizzes when the air inside is expelled. The concept of energy transformation is also noted (potential energy turning into sound energy), but not really explained. Have your start-up scientists watch this as an anticipatory set, or at home. Then they can come to class ready to discuss the concepts more in depth.
