Conventional environmental education is mainly of nature experience type, and many require time and place. A rocket stove is an efficient and hot burning portable stove using wood fuel. Especially since the Great East Japan Earthquake, there are many reports made as part of environmental activities. However, rocket stoves are not well known generally in Japan. In this study, we made a small rocket stove as a teaching material for environmental education. Furthermore, environmental education using small rocket stove was conducted at elementary and junior high schools and its educational effect was investigated. As a result, in environmental education, not only promotion of the interests of the environment and science but also the promotion of interest in disaster prevention was great effect. Small rocket stove had a small entrance and could not supply air, making stable combustion difficult. However, by improving the combustion section and reviewing the fuel, stable combustion became possible.
