Geoscience Teaching Using Local Geological Materials (6) : Utilization of Drilling Data Possessed by Schools as a Teaching Material in Combination with both Topographic Maps and Paper Models

abstract
This article is designed to show an example of utilization of drilling materials for understanding the concept of time. There are many articles on the use of drilling data for learning the distribution of strata. There is little literature on the interpretation of columnar sections of layers from boring materials in chronological order at an elementary school science class. It is important for students to have experiences to interpret the strata chronologically for understanding the law of superposition, a general law upon which all geologic chronology is based. When used in conjunction with topographic maps drilling materials become a learning tool to interpret geological columnar sections chronologically. It is easy to know topographic change in chronological order by comparison of two topographic maps. Each map covers the same area, but was published in different year. Though it is difficult to find topographic change recorded in the drilling materials in general, the change caused by art is not so difficult to find because of characteristic lithology of artificial sediments. By the comparison with topographic change in the topographic maps, elementary school students have a better sense of the lithological change in geological columnar section in chronological order.
