| Outline of Final Research Achievements |
Teaching materials for learning about regional natural history were developed using spring water which is the inland water environment representative of the Tokai region of Japan. In order to clarify the characteristics of the water quality of spring water with very little information, we carried out two years observation. From the results of field survey, we found that the concentration of silicic acid and, electric conductivity and inorganic nitrogen concentration were indicators about geology and human impacts, respectively. Human activities have a great influence on spring water quality from the results of field survey carried out at Nagoya and Toyota City of the Aichi Prefecture. On the basis of field observations, we practiced classes in the unit of "Flowing water works" of the fifth grade elementary school "science", and it was confirmed that spring water is suitable as a teaching material to understand the relationship between nature and human activities.
