Literature suitable for teaching internal plant structure in Nigerian schools is scarce. Author provides list of plants which could be used by teachers in Nigeria for teaching plant anatomy. All plants described are available in abundance in the Nigerian climate. (PS)

Suggests methods of teaching plant identification and taxonomic theory using keys, statistical analyses, and biometrics. Population variation, genotype- environment interaction and experimental taxonomy are used in laboratory and field. (AL)

Describes simple apparatus and procedures for demonstrating photosynthic rates when Elodea plants are illuminated simultaneous with long and short wavelength light. (AL)

Discusses U.S. National Parks as natural laboratories for the study of ecology, geology, earth science, and botany. Suggests activities which will enable children to more fully appreciate the great age of the earth, its history, the complexity of its structure and composition, and the myriad plants and animals which inhabit it. (BR)

The use of toluidine blue as a stain for plant tissues is advocated. Directions for hand-cut tissue staining are provided. (PEB)

Reviews six books that deal with dinosaurs, sea creatures, physiology, cacti, and cotton. (FL)

Procedures are outlined for a laboratory exercise in which students use a gravimetric method to determine the rate of transpiration in sunflower seedlings. Discusses the data in terms of the effectiveness of stomatal openings, mechanisms for water movement in plants, and the role of transpiration in the environment. (DC)

Results of a study investigating the nature of secondary school pupils' difficulties in understanding the concept of water potential are presented. Provides examples of common misconceptions. (CS)

Describes a procedure for the separation of coleus pigments using simple supplies and equipment from home and the supermarket. (MA)

Seven easy-to-do experiments with plants are outlined to aid in teaching children about plants: their search for water, food, and light; a variety of rooting systems; and the effects of soil temperatures. (JMF)

Describes how to grow duckweed in the classroom. Includes a classification key, illustrations of the plants, and activities for the care and study of duckweed. (MA)

Presents a science activity to help students to explore the concept of primary productivity by growing lawn grass in the classroom. (HM)

Discusses advantages of radial diffusion assay in determining presence of enzyme and/or rough approximation of amount of enzyme activities. Procedures are included for the preparation of starch-agar plates, and the application and determination of enzyme. Techniques using plant materials (homogenates, tissues, ungerminated embryos, and seedlings)…

Describes two investigative labs that use live plants to illustrate important biological principles, include quantitative analysis, and require very little equipment. Each lab is adaptable to a variety of class sizes, course contents, and student backgrounds. Topics include the evolution of flower size in Mimulus and pollination of Brassicas. (DDR)
