Recently, there have been many proposals and countermeasures for the purpose of the global environmental protection. Solar cell, windmill and fuel cell using clean energies are actively applied to home generation of electricity instead of using fossil fuel. However, teaching materials that are easy to understand regarding the use of clean energies are not generally used in elementary schools. Handicrafts and experiments using clean energies are especially required at early time of schoolchildren. This paper proposes handicrafts using solar cell, windmill and fuel cell suitable to address schoolchildren's needs. This paper deals with solar cells operated chain tower and merry-go-round, and wind power operated propeller type and signboard type windmills and Ferris wheel powered by a fuel cell.
