On the Google Maps Mania blog there is a list of 100 or more things you can do with Google Maps. I’ve used Google maps to show various demographic and physical features to students. Below you should see a Google Map of the Presidential Primaries with comments from Twitter users occasionally appearing on the map.

Application for Educators
Google maps can be used to show demographic data, physical features, political landmarks, and much more. The overlay feature of Google Maps is a good way to demonstrate to students how physical features impact demographic features. Use some the historical map overlays to show students how physical features played a role in military battles.
