MIT highlights High School content

As you check out content repositories, you'll want to note MIT Open Courseware now has a section for High School students and teachers.

MIT Open Courseware High School Highlights page (http://ocw.mit.edu/OcwWeb/hs/home/home/index.htm)

I would imagine much of this would need to be adapted for your use, but any new content resource for online teachers is a great resource for a Moodlebot.
