(CAHHP) is a science education outreach program that involves students in research of their own design related to indoor and outdoor air pollution and links with respiratory health. The program, which provides equipment, lesson plans, and support to middle and high school classrooms and professional development for teachers, is an excellent model of how to engage students in relevant and authentic science research and learning. This article describes the current program, how it promotes authentic science learning in secondary science education, and the positive impact it has had on student learning and attitudes.'
