So how big is space really?

This creative interactive allows you to pilot your rocket ship away from Earth and into the skies.  Along the way, you will pass a variety of natural as well as man made elements. Produced by the BBC, How Big is Space could be projected or as a station.  I was thinking of giving the students a list of some of the items (prior to exploring the site) and having them predict in what order they would see them.   You could debate the list as a class and then use the interactive to see how close they came!
