In one way or another, almost every form of energy we use originates from the Sun. Solar energy directly powers photo-voltaic cells and thermal collectors. Indirectly, we get power from plants grown by the sun, oceans heated by the Sun, and Earth's weather systems sustained by the Sun. Even the energy stored in fossil fuels originated as energy from the Sun, captured by plants and animals millions of years ago. Physics Solar Workshop explores the topic of solar energy, focusing on photo-voltaic cells. By building 12 models and conducting 30 experiments, you will learn how solar cells transform light into electrical energy, and how motors and mechanical devices can optimize the work done by this energy. You will build different types of vehicles and machines to demonstrate how gears can convert and transform power for different needs. The 64 page full-color manual provides instructions for the projects and experiments. 320 pieces. Ages 8 and up. |
