8A20.70 - Scale of the Earth/Sun/Moon System

Code Number:
Demo Title:
Scale of the Earth/Sun/Moon System
Relative Sizes
Area of Study:
Solar System
Earth, Sun, (Scale Models), Earth, Moon, (Scale Models), Page of Distances.

Make sure the teacher knows the size and distance relationships.  In scale it should be the 12 inch diameter sun and the 1/8th inch diameter earth at 100 ft. distance apart.  Also in scale the 1 inch diameter earth and the 1/4th inch diameter moon at 30 inches distance apart.
