Websites for classroom videos

I have recently been working on my short story unit and have come across several good websites that I wanted to share. The first is Watch Know Learn. The site has short useful videos from all over the web, not just YouTube. They can be downloaded and embedded into whiteboard presentations. My school has YouTube blocked and since you can't download the videos, I am often limited on what I can use. This site has a wide variety of subjects and even has a section dedicated to the Common Core. Check it out.
