Presents plant and plant ecology lessons designed to raise student awareness of the effects of human trampling on the environment. Involves students working in teams to determine which types of plants are more sensitive to trampling, and designing a method for testing the prediction. (JRH)

Introduces the plant Amaryllis, which is the common name for the Hippeastrum species. Describes how to grow and bloom Amaryllis in soil using hydroponics. Introduces experiments investigating the anatomy of the bulb, growing and elongation rates, the flower, and foliage. (Contains 21 references.) (YDS)

The author describes relationships between the fungi called mycorrhizae and plants. Describes the classes of mycorrhizae and the importance of such fungi in plant growth. Presents clear micrographs of the fungi and their interactions with plant root cells. Provides technological applications of mycorrhizae in agriculture and discusses problems…

Describes the life cycle of the Amaryllis plant from bulb to blossom. Suggests 12 activities in which students monitor plant growth, examine plant parts, make drawings of the plant, and eat flowers of other plants. (MDH)

Consumer chemistry projects using houseplant fertilizers are described. Background information on fertilizer elements and different brands are discussed. The procedures for the activities (reading fertilizer labels, calculating the cost of various fertilizers, and calculating the amount of nitrogen in solution) are included. (KR)

Describes symbiosis and its significance in the day-to-day lives of plants and animals. Gives specific examples of mutualism, commensalism, and parasitism in the relationships among fungus and plant roots, animals and bacteria, birds and animals, fish, and predator and prey. (MDH)

Describes the effects of thigmomorphogenesis, the mechanical stimulation of plants, and how to engage biology students in a study of this unusual plant response. Focuses on an exploration of the effect of wind on a particular plant variety. (DDR)

Discusses practical work which can be completed in a few hours that enables students to explore the genetics of the dandelion plant, which reproduces asexually. Dandelions, measuring instruments, and student imagination are needed for this activity. (DDR)

Details the teaching of an undergraduate plant-cell biology class in the manner proposed by Jean Baptiste Carnoy when he established the first institute of cellular biology. Integrates mathematics, astronomy, physics, chemistry, anatomy, physiology, and ecology. Contains 226 references. (DDR)

Suggests activities for studying the variety of life forms found and the interaction of living things during a class trip to the beach. (WRM)

Presents three activities using pearl onion bulbs to illustrate plant growth and plant propagation under various conditions. (WRM)

Details laboratory procedures that enable students to understand the concept of how differences in water potential drive the movement of water within a plant in response to transpiration. Students compare transpiration rates for upper and lower surfaces of leaves. (DDR)

Describes a project in which teachers concentrate on providing hands-on learning and work with students to build a nature center. Students participate in the planning, implementation, and evaluation phases of the project. (DDR)

Describes historical accounts dating back to as early as 604-562 BC of the various uses of hydroponics. Throughout the article, diagrams and simple instructions are provided to aid in classroom use of hydroponics. (ZWH)

Describes an experiment designed to teach students to accurately identify and measure changes in plant morphology and chemical composition due to environmental stresses. Contains 31 references. (DDR)
