Description: Project Learning Tree (PLT) is an environmental education program developed for both in-school and out-of-school settings. Curriculum guides for K-8 and for 9-12 are available and address a variety of multidisciplinary, ecologically-based science concepts. To obtain PLT materials, educators must first attend a training workshop. Workshops are free or run for a “nominal cost.”

From the website: “Educator workshops are open to anyone, held at convenient times, and are free or offered at a nominal charge. Through PLT workshops, you can:

-Learn how to incorporate PLT activities into your current and future lesson plans and curriculum.

-Meet other professionals in your area interested in environmental education.

-Become part of a network that offers you follow-up resources and opportunities.

-Learn about environmental education.”

A calendar of upcoming workshop events is available at or interested groups can contact the state coordinator (see contact information below).
