地域素材を活用した地学の学習(4) : 関連性を考えるツールとしての瀬野川の礫の円磨度
Geoscience Teaching using Local Geological Materials (4) : Roundness of river gravels as a thinking tool of correlation
Abstract
Size, roundness, and composition of river gravels of three localities in Senogawa and Kumanogawa Rivers, Hiroshima city, were examined. Gravel roundness was observed quantitatively to change in relation to upstream-downstream change within Senogawa River, and was determined visually and precisely by using a diagram showing classes of roundness. Results of classroom experiments demonstrate that the activities of determination of gravel roundness was suitable for elementary school students, and that gravel roundness was useful for a thinking tool of the correlation between localities in relation to the function of running water.
