Mix fun in the sun with learning about solar energy. With this kit, students enjoy creating fun toys that run on a solar panel with a 75 mA output. The 21 snap-together parts can be combined to build one of six possible models: car, walking dog, air boat, windmill, and two different planes. This kit is a great way to start teaching your students about renewable energy. Requires a light source such as the sun or a floodlight.
