This issue of The Science Teacher (TST) continues our tradition of devoting one issue each year to partnerships that connect students, teachers, and their communities. Science activities that take students outside school walls can combine the best aspects of community service, problem- and project-based learning, and lessons in good citizenship. Over the last five years, TST has published more than 50 articles describing community partnership programs. The model projects found in this issue add to TST’s archive of successful community partnership projects.
