Downie, Roger – Journal of Biological Education, 1987
Suggests ways in which hens' egg vitelline membranes can be used to demonstrate cell traction effects. Reviews procedures for using and culturing the membranes and identifies topic areas for student projects. (ML)
Descriptors: Biology, Culturing Techniques, Cytology, Laboratory Procedures
Peer reviewed
Humphreys, T. J. – Journal of Biological Education, 1987
Addresses problems associated with biology fieldwork and the teaching of ecology. Points out the need for the development of an objective approach in evaluating the effectiveness of fieldwork exercises. Reports on the evaluation of concept education by transect exercises. (ML)
Descriptors: Biology, Concept Teaching, Ecology, Evaluation Needs

Sutherland, William J.; Watkinson, Andrew R. – Journal of Biological Education, 1988
Suggests an approach and methodology for analyzing field and laboratory populations. Describes an experiment using mustard to show how competition and inequality can be assessed. Discusses the variables responsible for determining the abundance of organisms. (CW)
Descriptors: Biological Sciences, Botany, College Science, Ecology
Peer reviewed
Gow, Mary M.; Nicholl, Desmond S. T. – Journal of Biological Education, 1988
Uses simple models to illustrate the principles of this genetic method of mapping gene loci. Stresses that this system enables a practical approach to be used with students who experience difficulty in understanding the concepts involved. (CW)

Peer reviewed
Peters, R. C.; And Others – Journal of Biological Education, 1988
Presents a model system designed for the electrophysiological investigation of single unit activity in intact anaesthetized animals. Illustrates how information is coded into action potential patterns by sense organs. Uses the ampullary electroreceptor of the brown bullhead catfish as an example. (Author/CW)

Peer reviewed
Gill, John; Saunders, Terry – Journal of Biological Education, 1987
Presents investigations to explore the substrate specificity, pH, concentration, and temperature relations of an enzyme with only inexpensive commercial rennet and basic laboratory equipment. Describes how the activities were carried out with a group of 15-year-old students. (CW)
Descriptors: Biochemistry, Biological Sciences, Chemical Reactions, Enzymes
Peer reviewed
Aston, T. J. – Journal of Biological Education, 1987
Outlines an adaptive framework for the study of plants and their pollinators in which both partners in the ecological relationship are seen as maximizing fitness through efficient use of the other as a resource. Suggests experimental projects to examine the validity of these assumptions giving an evolutionary emphasis. (Author/CW)
Descriptors: Biological Sciences, College Science, Ecology, Environmental Education
Peer reviewed
Kinchin, Ian M. – Journal of Biological Education, 1987

Hitchen, Trevor; Metcalfe, Judith – Journal of Biological Education, 1987
Describes a simulation of the results of real experiments which use different strains of Escherichia coli. Provides an inexpensive practical problem-solving exercise to aid the teaching and understanding of the Jacob and Monod model of gene regulation. (Author/CW)
Descriptors: Biochemistry, Biological Sciences, College Science, Genetics
Peer reviewed
Allen, J. A.; And Others – Journal of Biological Education, 1987
Presents experiments using wild birds as predators and pastry as prey and colored stones as background to demonstrate natural selection. Describes the exercise as an exercise in simulating natural selection. (Author/CW)
Descriptors: Biological Sciences, College Science, Ecology, Evolution
Peer reviewed
Nicholl, Linda A. A.; Nicholl, Desmond S. T. – Journal of Biological Education, 1987
Describes how a series of models can be constructed to illustrate the structure of eukaryotic chromosomes, emphasizing the structure of DNA. Suggests that by adapting a different scale for each series of models, a complete picture of the complex nature of the chromosome can be built up. (TW)
