American Sociology Association  Resources for teaching Sociology in the high school classroom. Membership in the organization is pretty expensive, but they have a lot to offer for free.

 

The Society Pages ​​ An incredible resource, with a great blog.  This is written by two college professors, with a strong bent on feminism and gender.  While it isn't always appropriate for high school, it has so many great resources, it couldn't be left off of the list.
