The fine folks at Scientific American seem to be thinking along very similar lines. Under the aegis of the Nature Publishing Group, they're spearheading an effort called "1,000 Scientists in 1,000 Days" that "aims to help with all of those goals by making it easier for scientists and teachers to connect. The idea is simple. We seek scientists who are willing to volunteer to advise on curricula, answer a classroom's questions, or visit a school." They have a sign-up sheet for interested scientists - including a category specifically for anthropologists! - and they'll take care of matching interested parties with interested schools in their area. Sounds like a win-win to me, and you only have to volunteer as much as you are comfortable or able to. Get to it, folks!
