This fun hands-on astronomy activity lets learners explore models of the Milky Way and other galaxies to get a sense of relative distances to other galaxies. Part of the activity involves learners moving certain distances from each other to represent distances in the universe. Telescopes and night viewing are recommended but not required. This activity can be used with the general public at a star party, as well as with school-aged learners in a classroom. The PDF contains step-by-step instructions, photos, helpful hints, background information, and ready-to-print handouts. This is the English unit version; see related URLs for a link to the Metric unit version.
