distance from earth to moon.
Before beginning the technical aspect of this project, you will need to do a hands-on demonstration. During Module 2 you found circumference of the Earth at the Equator is just over 40,000 km. The average Earth-Moon distance is about 385,000 km, which is about 9.5 times the circumference. To make a quick scale model of this system, you will need a globe and a ball about a quarter of it's diameter to represent the Moon. Then, 1  Take a string and wrap it around the globe's equator about 9.5 times.
