The Tennessee Technological University's Program of Special Education sponsors a "Super Saturday" of enrichment activities for gifted and talented students as well as students with learning disabilities. A session on horticulture was planned and arranged by students in a class on horticultural therapy who designed learning activities of two types: general exploratory activities (Type I) and hands-on group activities for development of skill and practical knowledge (Type II). Type I activities, conducted during a two-hour morning session, included a hay ride tour of the farm, introduction to plant anatomy using a rubber tree, introduction to the water cycle, a slide show on transplanting and special plant structures, and a demonstration of the making of an air layer on a rubber tree. Type II activities, conducted during a two-hour afternoon session, included making a terrarium to demonstrate the water cycle, propagating new spider plants, transplanting greenhouse and nursery plants, and plant identification. Positive results included exposure of the special education students to horticulture, interaction among the two groups of students, and an opportunity for the horticultural therapy students to practice their training.
