This annotated bibliography of environmental education materials for preschool through grade 6 is intended for teachers and librarians. Most materials cited were published from 1970-1972, although a few date from the 1960's. The bibliography has two main sections: (1) preschool-grade 3 and (2) grades 4-6. A third and last section, an update of materials published from 1970-1973, cites additional materials not included in the main section. Within each section materials are listed by author under the following categories: (1) bibliographies; (2) books for students; (3) books for teachers -- activity guides; (4) curriculum materials; (5) filmstrips; (6) graphics; and (7) magazines.
