Physics Solar Workshop explores the topic of solar energy, focusing on photovoltaic 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. There are 320 parts, which are also compatible with the other kits in our Physics line. The 64-page book offers illustrated instructions for the projects. Developed with Greenpeace® in Germany. Ages 8 and up. • build 12 models, including a solar-powered tractor, truck, treaded vehicle, car, elevator, drawbridge, fan, airplane, mobile crane and construction crane • learn about harnessing and using solar power • learn about motors and simple machines.
