is a fantastic teaching tool. The windmill can be built by kids as young as 10, but I would recommend it to kids older than that with a better understanding of certain science principles. 
The windmill, once assembled, is a fully functioning small windmill. It uses high quality materials to allow it to withstand the elements. It includes everything your kids will need to build a vertical windmill, from recycled blades, s-foils to copper coils and five, ceramic grade magnets. Once assembled and stationed outside, it shows students how windmills can harness wind energy and turn it into electricity. At a wind speed of 12 mph you can produce approximately 3.0V/50mA. Overall, I think that this kit will add to students' knowledge of how wind power works, how to convert it into electricity, alternative energy resources, aerodynamics and other scientific principles. I am sure any student interested in science will appreciate this fun kit as a present.
