The development of available teaching materials for a certain region has been one of the most important problems in geological area of science education. We investigated the river bed gravel of the Midori River in Kumamoto to develop some regional teaching materials of elementary science. As a result of investigations especially focusing on the welded tuff, we found its suitable properties for learning on “Function of running water” and “Change of the land by the volcano”. Children may learn the erosion, transportation, sedimentation by running water and the spread of pyroclastic flow sediment from Mt. Aso by using the data about the size and distribution of welded tuff gravel. Using the welded tuffs as a key for linking science contents we developed the unit plan of “Function of running water”
