This interdisciplinary AAPT Digi Kit blends physics, geometry, and astronomy as students build and use a physical model to explore eclipse events as seen from Earth. Learners will configure the model to mimic the perfect Earth/Moon alignment that takes place during a total solar eclipse and compare relative proportions of the size of the shadow produced by their model to a NASA video of the shadow crossing Earth during a real solar eclipse. In addition, the Digi Kit integrates digital models, animations, and simulations to deeply explore eclipse phenomena. Included in the Digi Kit are an open source Astronomy textbook, math challenges, an activity to build a "sun funnel" to view the 2017 eclipse, and professional development video for teaching about orbits and eclipses.
