Realização de experiências em sala de aula de geografia: ensaio sobre deslizamentos

Abstract

The study aims to assess the relevance of constructing a model as a pedagogical strategy for the 9th grade Geography Teaching Unit (TU) on Natural Hazards and Disasters. The model is designed to support students' understanding of risk perception and the territorial planning measures necessary for risk prevention and mitigation. The methodology involved the selection of materials, model construction, and the execution of experiments. It also set out to identify factors that trigger landslides, and incorporated anthropic elements that either promote or are affected by such landslides. Different textured materials and waterproofing agents were used to simulate the processes. During the experiment, the effects of four geomorphological processes were observed: saturated internal flow, formation of 1st order water lines in mountainous areas, surface runoff (associated with soil compaction), and block fall/landslide. The results confirm that the model is an effective tool for understanding geomorphological processes and associated risks.
