Abstract
The aim of this study is to develop the workshop program that raises primary school students' potential to solve a given task by their collaboration. Each team composed by 3 to 4 participants makes the gimmick that a wooden ball put on the upper edge of the board reaches the lower edge of it as slow as possible on the inclined pegboard. Finally, all teams collaborate to make a long slope by connecting them. We tried to clarify how their consciousness would change through this experience.
