Evacuation routes and timing for volcanic eruptions vary depending on the crater's location and the volcanic phenomena. Therefore, making decisions based on scientific knowledge is essential to evacuate accurately. Education in elementary and junior high school is effective in acquiring scientific knowledge. Hence volcanic eruptions do not occur frequently and are difficult to experience, classes using simulated experiments are considered effective in helping students understand volcanic phenomena. On the other hand, although many teaching materials for experiments on volcanoes have been introduced, only some cases have been utilized. To adopt these experimental materials in their classes, teachers must usually prepare teaching plans, evaluation plans, and workprints. In addition, they need the materials, the skills to conduct the experiments, and the knowledge to explain the meaning of the experiments. Therefore, adopting them into a class requires more than simply providing experimental materials.
In this study, we developed experimental materials and a practical manual to facilitate the understanding of evacuation from lava flows, which has frequently occurred in past eruptions of Mt. Fuji. This teaching material aims to help students understand that the direction of lava flow changes depending on the crater's location and that it is necessary to move in a direction perpendicular to the direction of a lava flow. A 3D model and liquid soap are used in the experiment. At first, students assume that any point on the 3D model is a crater and predict the flow path of lava flow from there. Then, they pour liquid soap from the assumed crater on the 3D model and verify the flow path. In addition, they will use a geologic map to verify the flow paths of past lava flows and to understand the adequacy of these experiments.
In this report, we introduce the developed teaching materials, the demonstration lessons, and their effectiveness.
