Sun, Moon, and Earth Materials

This lab is a fun outside demo where you create scale models of the sun, moon, and earth, as well as have a good laugh as you introduce the concepts of rotation, revolution, barycenter (the funniest) and orbit. The students come out of this with a very good understanding of scale and terms.

Demo Kit includes: 1 ping pong ball, 1 tennis ball, 1 beach ball, 100 poker chips, 1 roll of string
