Great breadth and depth of knowledge. Accessible, honest.
I would use this instead of other sources such as Kids Health. Sex, Etc. allows students to have an unbiased source of sex ed information. I love the "state by state" breakdown of Sex Rights and resources for students. Lots of information that students could be afraid to ask adults or each other. Powerful tool for the birth control brochure project in my 9th grade class.
How I Use It
This makes a good resource for student-centered research. They can research biological, social, and policy related to sex, sexuality, and relationships. However, the large variety can be distracting for students.
