An instructor's manual and student activity guide on building a model greenhouse and growing plants are provided in this set of prevocational education materials which focuses on the vocational area of agriculture (ornamental horticulture). (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 (five days main activity, eighteen days for follow-up activity), activity goals, ten instructional objectives, and activity implementation (description, materials needed, safety considerations, teacher preparation prior to class, during the class, follow-up activities, answer key to student check point activity 1 and masters for duplication [e.g., objective 1 check sheet, plans for model greenhouse]). The student activity guide provides step-by-step instructions (narrative and illustrations) for completing each instructional objective (e.g., identify tools and equipment, build model greenhouse, plant seeds in greenhouse). At the end of each set of instructions is a student check point (evaluation activity). Five occupational descriptions (e.g., plant propagator, horticultural worker) conclude the document. (JH)
