This curriculum unit is intended for use in high school social studies, technology education, science classes, and in some career guidance classes. The lesson plans and activities are to help teachers present a comprehensive unit on manufacturing to their students. Activities provide hands-on, problem-solving, and cooperative work experiences. There are four lesson plans and a guide for setting up a factory visit. Lessons include: (1) "Why Study Manufacturing?"; (2) "The History of Manufacturing"; (3) "The Manufacturing Process"; and (4) "New Trends in Manufacturing." The unit also includes: a large colorful poster (not included here) for classroom display; a one-half hour videotape (not included here); a 28-item list of organizations, publications, and science and technology centers teachers may wish to consult; and a 25-item bibliography/filmography.
