Power House

This kit helps teach children how to harness the power of the sun and wind in 70 fun experiments and 20 building projects about alternative sources of energy. From evaporative cooling to solar cooking to setting up electromagnetic fields, the activities in this kit help children learn ecologically friendly lessons about the future of energy production. The model house comes complete with solar panels, a windmill, greenhouse, and desalination system, plus all the components necessary to build and operate an electric train, solar cooker, solar hot water tank, hygrometer, electric motor, power hoist, sail car, and more. It includes 96-page instruction and experiment manual. (And maybe the kids will turn off the lights more.)
