Use this model of the Milky Way and other galaxies to indicate relative distances to other galaxies
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.
This presentation includes a PowerPoint (.ppt) and suggested script (.pdf), along with suggested activities for presenting a scale model of the Solar System compared to our Galaxy. This is often referred to as the "Birdseed Galaxy" presentation.
Mentally construct a model of our place in the Milky Way Galaxy and the distribution of stars with just a coin and some birdseed.
The "Passport Through Time" handout shows the difference between each of three different distance categories: within our Solar System, within the Milky Way, and within the rest of the universe.
