What are some summer activities for middle to high school girls? (details enclosed)?

I work at an Alternative School for court ruled, neglected, and troubled teens, and throughput July, I have to plan summer activities for them. Due to the fact that it's an Alternative School, it is fairly strict and therefore, physical contact is a violation for the kids here. So, I need activities for these teen girls to participate in that lack much physical contact. Some of the ideas we have proposed thus far include Zumba, scrapbooking, movies, and making tie dye shirts. Keep in mind that my co workers and myself are 17 and 18, so maybe something that would be fun for ages 12 to 18? Thank you in advance (:
