nah sorry dont know about interactive sites, but last year i found www.s-cool.co.uk really helpful esp. for info i was lacking to write good essays! also the phillip alan sociology revision guides were a revision life saver!
This site I found has brilliant resources for Sociology. It has power point presentations, quizzes, crosswords, information reviews and all sorts. It is useful for both the OCR and AQA syllabuses I think.
Still looking for more interactive websites for family and households as well as education.. preferably a site you don't have to sign up to use as well!
