Curricular Units are multi-week groupings of lessons. TE Curricular Unit: Energy of Motion Grade: 7 (6-8) Summary The Energy of Motion unit begins with mechanical energy and its two simplest forms: kinetic and potential energy. Next, the concept that energy can change forms is introduced, with examples of kinetic and potential energy interrelationships. Using the example of a waterwheel, the concepts of work and power are examined. Conservation of momentum and collisions are explored, with analogies to popular sports, and how elastic and inelastic collisions are considered in the games' design. To show another energy transformation concept, the behavior of energy dissipating into heat by means of friction is presented. Finally, a summary lesson provides a review to tie all these energy of motion concepts together.
