Clicker is a good spot for Finding Videos

You may find that you like this site already and didn't even think about using it for school, but it can be. In my former life as a science teacher, I was always looking for videos. Well, Clicker houses thousands of videos from major movies to major TV show series to science videos. If you want to show a NOVA video, look for it here...it may be free! Same with other Discovery shows. Or maybe you want to use a piece of a movie or a show that the kids know...well it may be free or at least available to download for a price and now you can show it. I think this site is similar to Hulu.com, so you might try both. I just happened to notice the large amounts of free science shows from TV on this site first. Enjoy!
