Some of the basic things you can do with Google Earth are to see different landmarks and places you wouldn't normally be able to see. You can visit these places without leaving the house. There are other resources available at the different sites that allow you to learn more about that place. I con use Google Earth in my classroom to help my students learn the curriculum better. If they see it and experience it through Google Earth, it will make the subject matter much more interesting than just hearing about or even seeing pictures about it. The other resources and videos available at the sited will also help them learn better.
