Geopedia is a nice combination of a map and Wikipedia entries. Search for a location on the Geopedia map and you will be shown a bunch of map placemarks around that location. Click on any of the displayed placmarks and you will see a corresponding image and Wikipedia entry. To change locations you can either right-click on a new area of the map or enter a new search term.

Google Earth has a Wikipedia layer that does essentially the same thing as Geopedia. Unfortunately, Google Earth will only work on a Windows or Mac computer. Geopedia provides a nice browser-based alternative to the Google Earth Wikipedia layer.
The Geopedia map offers students a good way to see the correlation between places and events.
