The 6-In-1 Educational Solar -- Robotic Kit is an excellent beginner building kit designed to teach how solar power is used to drive a small motor. Children use the 21 snap together parts (no tools required) to build six different working models including an airboat, car, windmill, puppy, and two different airplanes. Solar building kits teach children the benefits of solar energy, while they create a toy that is both fun to play with and requires no batteries. Educators, science museums, and hobbyists will surely appreciate the durability, educational value, and endless hours of amusement for children and adults too! This is a beginner kit recommended for ages 10 and up
