Pocket Solar System: Make a Scale Model
This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape. Learners are often surprised to find how empty the outer solar system is (there is a reason they call it space!) and how close, relatively speaking, the orbits of the planets of the inner solar system are. The pdf contains step-by-step instructions, photos, presentation tips, common misconceptions about our solar system, and links to background information.
