This document consists of a student resource book entitled "CAAP in Action: The Environment" and an instructor guide entitled "CAAP in Action". CAAP is a program developed by the Close Up Foundation, a nonprofit, nonpartisan civic education organizations, in cooperation with the National Association of Elementary School Principals (NAESP). The program is funded by Burger King Corporation. CAAP is designed to help students learn about environmental problems and understand them as civic issues that can be addressed by their own personal actions. The resource book has three parts. First, in a Learning Project, students learn about the environment by reading an essay, studying a timeline, and completing work sheets. Next, students are asked to choose a topic about the environment and study it in depth by doing a Research Project. Finally, students conduct a Civic Project about the environment. This resource book is part of CAAP in Action, a special shortened, topical version of the Civic Achievement Award Program (CAAP), that was established by Congress in 1987 as an interdisciplinary supplement to the social studies curriculum for grades five through eight. The instructor's guide is designed to help teachers to implement an interdisciplinary program in which students learn about environmental problems and come to understand them as civic issues that can be addressed by their own personal actions.
