The "Project WILD Aquatic K-12 Curriculum and Activity Guide" emphasizes aquatic wildlife and aquatic ecosystems. It is organized in topic units and is based on the Project WILD conceptual framework. Because these activities are designed for integration into existing courses of study, instructors may use one or many Project WILD Aquatic activities or the entire set of activities may serve quite effectively as the basis for a course of study. Each Project WILD Aquatic activity contains all the information needed to conduct that activity including objectives, method, background information, a list of materials needed, procedures, evaluation suggestions, recommended grade levels, subject areas, duration, group size, setting, and key terms. A glossary is provided, as well as a cross-reference by topics and skills. The guide is divided into three sections: (1) Ecological Knowledge; (2) Social and Political Knowledge; and (3) Sustaining Fish and Wildlife Resources. Appendices include: (1) Conceptual Framework; (2) Aquatic Extensions to Project WILD K-12 Activities; (3) Outdoor Classrooms; (4) Field Ethics; (5) Observations and Inferences; (6) Interviewing People; (7) Animals in the Classroom; (8) Using Local Resources; (9) A Guide to the Ecosystem Concept; (10) Keeping Classroom Aquaria: A Simple Guide for Educators; (11) Service Learning; (12) Evaluating and Assessing Student Learning; (13) Skills Index; (14) Topic Index; (15) Expanded Topic Index; (16) Metric Conversion Chart; (17) Glossary; (18) Agencies and Organizations; (19) Acknowledgements; (20) Project WILD Supplementary Resources; (21) Data Collection Form; and (22) Alphabetical Listing.
