Description

When pupils learn about earthquakes, they seem to have some difficulty in understanding the concepts because of the insufficiency of adequate teaching tools in most schools. Therefore, we tried to make three physical models which might be useful in visually understanding the following subjects: (1) the three-dimensional plate structure around Japan and its connection with earthquakes. (2) the mechanism of interplate earthquakes between subducting oceanic and continental plates, and (3) the three-dimensional distribution of earthquakes in and around Japan. We named them (1) "Why Do Earthquakes Occur?". (2) "The True Character of Earthquakes" and (3) "Where Do Earthquakes Occur?". Subsequently, using these handmade physical models, we conducted a practical science classin a junior high school. During the class, we found that each of the models succeeded in attracting the interest of the pupils. However, the effectiveness of the models as leaching tools has not yet been sufficiently investigated. More investigation is necessary to draw a definite conclusion on the effectiveness of the models.
