Google Earth is a handy tool.
I don't think that I have even scratched the surface on the potential of Google Earth in my classroom. I look forward to finding more creative ways to utilize it.
How I Use It
As a Band Director, I have used Google Earth to plot load in locations at different venues. We have used it for directions. It is a great way to get my music appreciation students the lay of the land when discussing geographic locations such as: Beale Street, Carnegie Hall, and the Grand Ole Opry.
