This paper focuses on educating children on wind power generation using educational models of windmills/turbines. In general, the performance of a wind turbine is measured in terms of power generation. In this study, we focus more on the windmill as an educational model than on its power generation capabilities. First, we queried elementary school students and junior high school students on windmills and their various components. First windmill was a lift/drag compound-type windmill, operating as a lift-type mill in headwinds and a drag-type one in tail winds. The next windmill was a drag-type one, and the students found the design of this windmill interesting. Although its power generation performance is low, it can rotate even at low wind speeds. Our third windmill was the lift-type-vane wind turbine that afforded the highest power generation performance. In general, the fabrication of lift-type vanes is difficult; however, we present an easy approach to fabricate lift-type vanes. A vane in this windmill consists of ribs, beams, and film. We plan to use these three windmills for educating students.
