Elliptical Orbit Demonstrator

Graphically Illustrate the Paths of the Planets

We know the planets revolve around the sun…but what ellipses do they travel? The answer is based on a simple mathematical equation called the “eccentricity equation”, and you can put it into motion with this demonstrator that fits on your overhead projector. It comes with string, four bolts, eight nuts, and a teacher’s guide that contains background information, student activities, and facts about the solar system. Size: 10"L x 10"W.
