Here is a sample letter to a mentor requesting help with an environmental science project.
Dear Dr. Janecky,
We found your name in the Challenge data base of mentors. We are a team from a middle school near a mine. We would like to figure out if it really is bad for our health to hang out near the tailings. Our parents tell us not to go there but we would like to figure out if it really is dangerous. You can reply to us at this email address which we check every day.
Thank you for your help.
