Abstract
The teaching tool for learned the mechanism of wind power generation in junior high school industrial arts and homemaking course was developed. Developed teaching tool is a windmill of the savonius-type. The magnetic levitation bearing has been installed so that the impeller may lightly rotate. The rotation of the blades are accelerated by the gear, and the magnet rotates it. The transformer has been installed at the lower, and the electricity is being generated by the change of the magnetic field. The main body is made in the transparent acrylic pipe, as to observe the transmission of the power is possible. The class practice was carried out by the utilization of this teaching tool for junior high school students. As the result, it was possible to learn the mechanism of the wind power generation experimentally, and the fixing of the learning heightened.
