This website has links to many resources for teachers as well as this competition:
Exploration of the Moon and Asteroids by Secondary Students (ExMASS)
The Center for Lunar Science and Exploration (CLSE) at the Lunar and Planetary Institute and NASA’s Johnson Space Center is looking for 10 teams of motivated high school students and their teachers to participate in a two-semester, national standards-based lunar/asteroid research program for the 2014-2015 academic year. Working alongside their teachers and a scientist mentor, students undertake an authentic, open-inquiry research project that engages them in the process of science and supports the science goals of the NASA Solar System Exploration Research Virtual Institute (SSERVI). At the end of the year, student research is reviewed by a panel of scientists. The top four teams then present their research to this panel of scientists, competing for a chance to present their work at the Exploration Science Forum held at the NASA Ames Research Center in July 2015.
This might be a great competition to get into! It is for sure a cool thing to offer the more advanced students looking for something more to do in space science!
