Our Place in Our Galaxy

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed. This is a great introduction to the distances of objects in the universe. This activity was designed for use with sky-viewing telescopes but can be adapted to many venues. The PDF contains step-by-step instructions, photos, presentation tips, background information, and ready-to-print activity handouts.
