Hulu is probably best known for the numerous sitcoms, dramas, and other entertainment television shows that it makes available for free. But did you know that Hulu also offers some good educational material too? One example of the educational material you can find on Hulu is their collection of 23 full-length episodes of NOVA. While you can also view these videos on PBS Video, the advantage that Hulu offers is the option to embed the videos into your blog, wiki, or website. Of course the disadvantage is that Hulu doesn't offer teaching guides. You will have to find those on the NOVA teachers' page.
