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