Teaching with Technology Part 1

I'm interesting in teaching with Google Earth. I was reciently on it for the first time the other day and was amazed about all that you could do. First I just typed in my address to see if it would come out to the correct place and to my amazement it not only took me to the right place on the map but it had a live picture of my house with my car in the driveway (was concerened about why this picutre was up on the internet though). Then after I did my address I started looking around the world and I found that you can not only see pictures of major monuments but you can actually get information off of it too. How can I use that in my classroom?
