The U.S. Environmental Protection Agency's Indoor Air Quality (IAQ) Tools for Schools Program is a common sense approach to improving your school's indoor environment. Students can take the lead on implementing this program, and many teachers have already begun to involve students of all ages in IAQ activities. The NEA Health Information Network has established this listserv so teachers may exchange ideas and activities that improve the indoor environment and achieve academic goals by involving students. Because we spend 90% of our day in buildings, the indoor environment is truly the human environment. Join now!
