This manual is one of a series designed to assist junior high school teachers in developing general level or non-academic science programs which focus on the relationship between science and society. Although designed primarily for grades 7 and 8, the content is also suitable for students in grade 6. The major portion of the manual consists of six teaching episodes. Each episode begins with a curriculum summary which outlines the content, teaching essentials, objectives, and evaluation examples (keyed to objectives). This is followed by a detailed description of how to teach the lesson, indicating how the flow of instruction should go to make maximum use of the manual. All episodes are tied together by a story line to help students understand that knowledge of the classification of living things is useful in enhancing such outdoor and leisure activities as hiking and bird watching. The manual also takes account of the relationship between classification in biology and the "everyday language" or informal classification schemes with which young students are already familiar. Teacher and student resource sheets to accompany the episodes are provided in the appendices. (JN)
