Problem:
Make a comparison between the size of two astronomical objects of your choice. Here are some suggestions--you can use any one of these, or pick something else that interests you! You may directly calculate them or you may look it up on the internet. The point is to develop a sense of scale between these objects. How many "Earth to Proxima Centauri" lengths fit inside the Milky Way galaxy? How many Suns could fit across the diameter of our solar system? How many Milky Ways can fit between the Milky Way and Andromeda galaxy?
