There's lots more on this site, including a library of outreach activities and resources used by people in the department! You just need to register for an account (or log in) in order to see it.
Request from Math Department. Dave Bock, Outreach Coordinator, seeks astronomy grad students (or others) to speak at teacher workshops in the future. He is interested in sharing with math teachers ways that math is used in astronomy. He says he is "thinking along the lines of algebra, geometry, trig, trajectory curves, etc (and pretty pictures, of course)". You can contact him at deb37@cornell.edu.
