Flickr as a visual learning tool

I just played around with some photos and picked where I took them. This would be a great tool to use in school for anything to that had to do with a project on your family, family, family vacation, travel's of certain individuals to use as a visual tool of sorts. Oh I could think of tons of ways to use this. I had this great idea for biology if your studing ecosystems. You could have the students go and take pictures of the place. And describe it and then link it to a map and let them present their findings in class. I think they would have a blast. You could have them use pictures they took on trips and all sorts of things are encourage them to explore their own neighborhood. Cool tool!
