Project Learning Tree in Pennsylvania


Project Learning Tree (PLT) is an award-winning environmental education program designed for educators working with students from pre-kindergarten to twelfth grade.  Through hands-on, interdisciplinary activities, PLT helps young people learn how to think - not what to think - about complex environmental issues.  PLT can help address state and national standards.  It provides the tools educators need to bring the environment into their classrooms and the students into the environment. 

Project Learning Tree is the environmental education program of the Americal Forest Foundation and is co-sponsored in Pennsylvania by the Department of Conservation and Natural Resources and the Pennsylvania Association of Environmental Educators.
