Speak Truth To Power: a free Human Rights Education Curriculum
http://blogs.nysut.org/sttp/curriculum/ has several free, well-written lesson plans on human rights subjects including children's rights, slave trafficking, freedom of expression and domestic violence. Some (all?) have special interviews for the project, including one with Vaclav Havel at http://blogs.nysut.org/sttp/defenders/vaclav-havel/
Most are for grades 9-12, some for 6-8.
