GreenWorks!

From site:  Project Learning Tree® (PLT) is an award-winning national environmental education program for educators and their students in grades PreK-12.  GreenWorks! is the service-learning, community action program of PLT that partners PLT educators, students, and communities in environmental neighborhood improvement projects. GreenWorks! blends service activities with the academic curriculum and addresses real community needs as students learn through active engagement. 

GreenWorks! action projects make a difference in young people's sense of responsibility toward their communities, and in their understanding of their relationship to the environment.  Some examples of past grant projects include habitat restoration, watershed improvement, outdoor classrooms, and energy conservation.

PLT provides a helpful guidebook with practical ideas and pointers for getting a GreenWorks! project off and running.
