Sun-Moon-Earth Solar Eclipse Demonstration: 1.Direct beam of flashlight on the larger ball. 2.Move smaller ball through the beam until its shadow falls on the larger ball. 3.Adjust the distance between the 2 balls until the shadow of the smaller ball completely darkens the larger. 4.Demonstrate differences in orbital planes
Sun-Moon-Earth Moon Phases and Eclipses 1.Identify which phase(s) of the Moon make(s) it possible for an eclipse to occur. 2.Infer why a lunar and solar eclipse do not occur every month 3.Explain why only a few people have experienced a total solar eclipse. 4.Diagram the positions of the Sun, Earth, and the Moon during a first quarter moon. 5.Infer why it might be better to call a full moon a half moon.
