Abstract



Using a modeling approach, this article discusses how to build a GeoGebra model to help students make sense of a total solar eclipse. A few powerful tools in GeoGebra such as sliders, tangents, animation allow students to explore the mathematical dynamics of a solar eclipse and identify the causes behind a total or partial solar eclipse.
