UC Irvine students are heading back to elementary and middle school classrooms to teach students about climate change. CLEAN Education designs grade-appropriate lessons using everything from hand-held puppets to ecosystem models made of plywood and papier-mâché. The nonprofit’s acronym comes from its mission to address climate change through learning, empowerment, action and networking. “Our goal is to discuss climate change in an engaging and fun way to get children interested in science,” says Francesca Hopkins, group co-founder and Earth system science doctoral candidate.Humanities
