This manual is intended to serve as a sourcebook for Volunteers and others to draw upon when implementing educational programs. The activities here are primarily organized according to subject matter, such as soil, water, trees, nature awareness, and ecology, with additional activities included under Service Learning Activities and Games. For ideas about how to develop programs, consult these Peace Corps manuals: Environmental Education in Schools (No. M0044) and Nonformal Education (No. M0042).
