Designed for use when the student or the class is expected to grow a crop using the high school greenhouse, these learning activity packages are sequenced in typical greenhouse cropping fashion: (1) poinsettias in the fall, (2) Easter lilies (bulb crop) in the winter, (3) bedding plants (seed crop) in the spring, and (4) a nursery crop (from cuttings) in the summer. Included within each of these four areas are activities such as selecting crops, propagation, preparing soil mixtures, and transplanting. Each of the twenty-five learning activity packages is divided into the following parts: introduction, directions, objective, learning activities, tools and equipment, materials and supplies, safety, instructions, student self-check with correct responses, and a final check-out activity. In addition, an instructor's final checklist is included with each package. (LRA)
