An instructor's manual and student activity guide on the seed bed are provided in this set of prevocational education materials which focuses on the vocational area of agriculture. (This set of materials is one of ninety-two prevocational education sets arranged around a cluster of seven vocational offerings: agriculture, home economics, distributive education, health occupations, world of work, trade and industry, and office occupations.) The instructor's guide is organized into the following elements: title of activity, duration of activity, (four to ten periods), activity goals, instructional objectives for eight occupations (farmhand I and II, hotbed worker, farm hand inventory clerk, sales representative, farm hand sales, county farm agent, and truck farmer), related vocational clusters, and activity implementation (description, materials needed, safety considerations, teacher preparation prior to class, during the class, follow-up activities, and two master sheets for duplication). The student activity guide provides step-by-step instructions (narrative and illustrations) for completing each instructional objective. The activity is based on preparation and care of seed beds and care and sale of tomato plants. At the end of each set of instructions is a student check point (evaluation activity). Occupational descriptions for inventory clerk, sales representative, farmworker, and horticultural worker I & II conclude the document. (JH)
