Now-a-days, global warming, caused by the burning of fossil fuel, has been attributed to unusual weather conditions in the world and the melting of ice in the Arctic Ocean. In order to address this global challenge, there have been various activities in almost every society. Solar cells and fuel cells using clean energies are actively applied to the generation of electricity in homes and electric vehicles instead of using fossil fuel. Recently, solar generation systems, with a capacity of 30 kW have been installed in Huis Ten Bosch as an electric source for the theme park. 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 an early time for schoolchildren from the viewpoint of ecology. This paper proposes a model of an amusement park in the near future operated by clean energies as teaching materials of elementary schools. Handicrafts using clean energies are a cable car operating on a fuel cell aided by a solar cell, a balloon tower and an electric train operated by a fuel cell.
