My friend is a 7th grade teacher and has asked for help finding resources she can share with her students. Web sites, videos, books, etc. appropriate for a Jr High/middle school level. Specific topics she'd like to cover would be: time travel economics (socialism vs capitalism - real economics, not 1950s propaganda videos) evolution I'll post more topics if she gives me more. Her initial request was for resources on time travel. I think these are for her students to study on their own, for those who are interested. So what resources would you all recommend?
