Really cool idea using Google Earth to take students on tours of literature. The site focuses on individual books (such as The Odyssey) and where those books take us. You can download pre-made maps (some examples are Night, Kite Runner, and of course, The Odyssey).
Of course, you can also create your own lit trip using Google Earth. Just add a few points, connect them with lines and/or arrows, and go on a virtual tour of Earth.
Another idea I had is that we could also outline a whole curriculum in Google Earth. Instead of one book, we look at all of the books we study over the course of a year (i.e. The Whale Rider, Greek Mythology, The Odyssey, Romeo & Juliet, etc.) and all the places those books take us.
