This educator's guide contains background material and stimulating activities pertaining to wetlands that classroom teachers, refuge managers, nature center interpreters, park service educators, and others will find useful. The first part, background material for teachers preparing wetland study units, is divided into six chapters: "Wetlands and People: Through Time and Across Borders", "Defining Wetlands", "Wetland Functions", "Wetlands as Home", "How People Manage Wetlands", and "Action for Wetlands". Each chapter starts with a short list of themes and recommended activities. Information throughout the background chapters is cross-referenced to specific activities. Materials on organizing field trips, making inexpensive sampling equipment, and getting involved in wetland enhancement and stewardship are also included. The activities are separated into the following groups: general wetland concepts and definitions, plants and animals, water, soil, and culture and issues. Suggestions for wetland study units for various age groups and logical activity sequences are also included. Contains appendices on planning and developing a schoolyard wetland habitat and a list of educational supplements, books, films and videos, posters, and organizations to contact for assistance. (JRH)
