Exercises are presented for classification of marine algae on the basis of biochemical characteristics such as pigmentation, cell wall components, and food storage products. (BB)

Described is an experiment designed to illustrate photosynthesis. The experiment is based on a classic experiment performed by vanHelmont in the sixteenth century. A list of materials, procedures, and concepts are discussed. Variations are suggested. (CW)

Describes the usefulness of glyphosate for a demonstration of its herbicidal properties. Includes a list of the materials, preparation of solutions, procedures, data collection and analysis for three activities involving this chemical. (CW)

Describes an experiment designed to use the ability of duckweed to convert the secondary hydroxyl moieties into ketone groups. Discusses the preparation of plant material, materials, procedures, and results for this biotransformation experiment for undergraduate students. (CW)

Discusses ATP synthesis in mitochondria/chloroplasts and cause of an antipodal high tide. Also discusses a simple field experiment on regulation of osmotic potential by Salicornia (pioneer plant of estuarine sale marshes) and use of a key to identify British mosquito larvae. The latter includes procedures for collecting, recognizing, and finding…

Describes laboratory procedures, demonstrations, and classroom activities/materials, including rapid peat-depth surveying; leaf-flotation method for measuring photosynthesis, an educational game demonstrating basis of protein synthesis, daffodil phototropism; chromatography apparatus; egg white digestion, and chromatography apparatus. Also…

Describes laboratory procedures, demonstrations, and classroom activities/materials, including water relation exercise on auxin-treated artichoke tuber tissue; aerobic respiration in yeast; an improved potometer; use of mobiles in biological classification, and experiments on powdery mildews and banana polyphenol oxidase. Includes reading lists…
