This is the entire manual for the Our Galaxy, Our Universe outreach toolkit. Two of the most misunderstood concepts in astronomy are distance and scale. Related to those are the difference between the solar system, the galaxy, and the universe.

The toolkit consists of activities and resources that are designed to help your audiences visualize the basic structure and organization of our galaxy and the rest of the universe, and the place of our solar system within it.

Links to videos below show the activities in action.
