I assist with the IT department at my childrens school and have put together a kmz of some ways that Google Earth could be used in a classroom situation.

It is by no means comprehensive but was put together to demonstrate the functunality to teachers. (Something I have been asked to do for a number of schools in a rural cluster including Primary and Secondary schools).

Some of the tours have been posted before (ie. The london attacks) and I by no means am claiming credit for the efforts of others that have been put in to them.

Hope this gives educators an Idea of what you can do (Just scratching the surface here) with G.E.

Pretty good ideas. I wish my teachers would have used this stuff while I was in school.

Great work on that collection. Love the pollution map.
