What causes an eclipse? How are solar and lunar eclipses different? Use this model to demonstrate how both solar and lunar eclipses occur. As students make observations, their partial understanding of these astronomical phenomena will move toward totality with this simple yet effective demonstration. Includes teacher instructions, detailed background section and student worksheet.
Concepts: Solar vs. lunar eclipses. Time Required: 15 minutes Note: Requires flashlight or other light source.
