See how a spinning pinwheel, a strumming guitar and a crackling fire all serve as great examples of energy at work. Dynamic graphics and fun examples teach kids how heat energy moves and how it affects atoms. Young viewers find out that the sun is the ultimate source of Earth's chemical energy and that sound is a form of mechanical energy. The program also introduces other forms of energy, including electromagnetic and nuclear.
