A resource/curriculum guide developed for teachers of grades 4-6 is intended to help Iowa students learn about agriculture in Iowa: its importance as the state's major industry, its role as a source of employment and careers, and its role in meeting basic human needs for nutrition, clothing, and shelter. The guide recommends that, wherever possible, students should be given the opportunity to learn directly from people connected with agriculture, such as classroom speakers, on field trips to farms or vocational agriculture laboratories, and by visits to agriculture fairs and shopping center exhibits. Five basic elements to aid teachers are included in the seven units: a 45-item pre/post test for diagnostic and evaluation purposes; background information for each unit; suggested activities and masters for reproduction; resource lists of materials, people, and possible field trips; and a key system to distinguish between student activities, student information sheets, transparency masters, student "just for fun" sheets, and teacher information pages. The units are "The American Farmer: The First 200 Years,""The Challenge of Farming,""Life on an Iowa Farm,""What Agriculture Does for You,""Iowa--The Land and its Products,""Eating for a Happy, Healthy Body," and "A Glimpse into the Future."
