The Scale of the Universe

I’ve seen this link before, with an older version on scale. This is a newer version, and includes some entertaining information about each of the items that are included in this interactive website. Everything from the width of a human hair to the size of an ultraviolet ray is included: it’s a great way to show students how small (or large) things are–plus it’s just fun to play with! 🙂
