The CassioPeia Project is a project that provides high quality science education videos available to anyone.
It was started in 2008 and has over 100 videos available on their site for download, on iTunes, and on YouTube. Topics range from quantum mechanics to chemistry to general physics. Their slogan is "No science teacher left behind" and they are funded by an anonymous retired scientist.
All of the content is open-source and educators are encouraged to customize the videos for their needs.
This is a great resource for anyone teaching, or learning, science.
