Want to build fun solar-powered vehicles and devices that move using electricity generated directly from sunlight? With this kit, you can construct five motorized models. Build three types of solar cars, a solar fan, and a solar robot model. Conduct science experiments with each model to learn about gear ratios, solar cells, and more. The ultralight materials, including strong bamboo rods, make your models speedy and durable. A modular gearing system lets you test out three different gear ratios.Experiment with a solar cell, electric motor, gears, and ultralight materialsBuild five different solar-powered modelsLearn about how solar cells work and about the energy from the sunsolar.  Recommended for ages 8 and up.
