If you have ever wondered where we fit in the universe, then this interactive is for you. The Scale of the Universe takes you on a ride down to the smallest thing theorized by scientists and then out to the vastness of the universe.
The interactive opens with a variety of objects shown on the screen, from a Giant Earthworm to a hummingbird. Below those images is a scroll bar that you can use to explore a diversity of sizes. You can move the scroll bar to the left to view smaller and smaller objects, while moving it to the right allows you to view larger and larger ones.
This resource can be used to help enhance any unit on the universe or the structure of matter. This resource is so simple to use and understand that it could work well in a variety of settings. You can use it as a starting point to talk about the structure of matter and the building blocks of matter—atoms. Or, you could go the other way and use the resource to help give students a feel for the size of the universe.
The interactive provides students with a visual reference for some of the various structures that they would cover in a physical science class. It also could be tied into a conversation about the roles that microscopes and telescopes have played in helping humans see and understand things that cannot be viewed unaided by the human eye.
