Very nice 5x5 cell matrix measuring technology integration from Florida Center for Instructional Technology. There are quicktime videos of lessons available as well.
TerraFly, a site provided by Florida International University and sponsored by the National Science Foundation, NASA, the United States Geological Survey, and IBM, contains a huge database of aerial and satellite images of the entire United States. The site includes a satellite link that serves up images of Earth close enough to identify city streets, parks, and other geographical landmarks. Visitors type in any U.S. address, ZIP code, or city and state for a virtual flyover of the area selected.
