FactCheckEd.org - Annenberg Classroom Fact Check

I ran across this great site in the Librarians' Internet Index blog feed for FactCheckEd.org - Annenberg Classroom Fact Check. In the site intro, they convey the following mission for their site:

"Our aim is to help students learn to be smart consumers of these messages, to see through the deceptions that they encounter daily, to dig for facts using the Internet and other resources, and to set aside prejudice and weigh evidence logically."

While intended for a high school audience, I think that most of the content could be modified for use with middle school students as well. This site offers a wonderful collection of lesson plans that would be appropriate for all core subject areas, including math (Suspicious Statistics) and science (Listerine). This site will work well with writing argumentative essays, debates and studying media awareness.
There is a topical search for Internet resources and "A Process for Avoiding Deception" for students to consider when conducting research.
The creators have included a helpful little dictionary (really a glossary), encourage you to ask them questions and an open discussion forum in the Faculty Lounge.
