In this study, we developed a simulation game called "Human SUGOROKU" that consists of a full-body interaction system to enable elementary school students to enjoy and learn vegetation succession. The students' sense of immersion is improved by enabling them to play this game using their body movements. We conducted an experiment with the students and investigated the affects of the full-body interaction through questionnaires. The results showed that the full-body interaction promotes a sense of immersion in the game and enhance their understanding of vegetation succession. This paper describes the structure of this system and the questionnaires results.
