Geo-Electric Field Science: Using Topographic Maps and Clay Models to Teach Electric Field and Potential
written by
Rebecca E. Vieyra
In this activity for high school physics, students build a physical model to apply and extend their knowledge of electric fields and potential. It engages learners in analogical reasoning, a type of thinking that can generate deeper understanding of abstract concepts. Students will use topographic maps to create clay models with contour lines, which will serve to represent electric potential. Through the analogy of topographic map/equipotential, learners can be expected to gain insight into electric field patterns and variables that influence strength of field. An extension activity includes a video of electric field lines using potassium permanganate.
