This BBC site is awesome. I plan on showing it to my students soon, to have them really appreciate the scale of historical and scientific events. The site says to type in your zip code, but it is even better if you type in your whole address. Then you choose the event. Want to see how big the Egyptian pyramids really are? Center them on your home address and you can see how much area they would occupy. How big was the oil spill? How far did Hannibal actually march?
I love this site and think your students will get a new understanding of events, both current and past. Also, to see how big the moon actually is compared to an area they understand - very interesting.
