Project "Green Footprint" is a local community environment project created by fifth-grade students to remind the citizens of their school (and Earth) to tread lightly on Mother Nature's creations. The students chose to focus on the air quality outside the school, specifically the carbon emissions produced by idling cars. Students complete Internet research, create pamphlets, give presentations, and take on other activities to alert the school community to local environmental issues. In this article, the author discusses the multidisciplinary activities involved in the project and describes how the students inspired their community and raised their self-worth through the "Green Footprint" project.
