Described is a simulation game designed to reinforce the biological concepts of poisoning, encourage critical thinking and deductive reasoning, and be enjoyed by the students. Discussed is the plot design, the setting, the characters, the analysis, and results of the simulation. Examples of the data and case histories generated by this game are…

Described is a simple technique to monitor air pollutants and to simulate some of the features of roadside canopies. Included are the procedures, directions for the assembly of the apparatus, and a discussion of typical results. Graphs of sample data are presented. (CW)

Described is a laboratory experiment that can be used to investigate bacterial survival in soil or water as well as the study of genetic transfer via conjugation. Discussed are materials, laboratory procedures, typical results, and a list of six references. (CW)

Discussed are the needs and objectives that should be evolving in biology education to meet the needs of modern students. Stressed are the principles of curriculum integration, relevance, cultural fitness, and adaptation. Directions for educational reform are described. (CW)

Two Hypercard stacks are reviewed including "Amino Acids," created to help students associate amino acid names with their structures, and "DNA Teacher," a tutorial on the structure and function of DNA. Availability, functions, hardware requirements, and general comments on these stacks are provided. (CW)

A review of some of the different forms that biological ethics have taken in the past and of issues which are arising suggests that ethics should be taught as a part of biological education within a framework of history, futures study, training in clear thinking, and the development of empathy. (Author/CW)

Instructions are given for constructing two models, one to illustrate the general principles of symmetry in T=1, T=3, and T=4 viruses, and the other to illustrate the disposition of protein subunits in the T=3 plant viruses and the picornaviruses. (Author/CW)

Described are the use of two different tests designed to test for selected inquiry skills. Procedures, tests used, and results in several different countries are presented. Implications for classroom instruction are discussed. (CW)

Lichenometry is described for use in the study of biology and physical weathering. Discussed are lichens in general and an outline for studying growth and ecology. A problem solving format is used. (CW)

Describes the use of a microwave oven in the biology laboratory as a safe, time-saving device. Discusses media preparation, dehydration of media and specimens, and reagent testing. (CW)

Reported are the differences in the understanding of concepts involved in photosynthesis and its role in ecology between students who had studied advanced biology and those who had not. Reports that the less experienced students had a poorer understanding of autotrophic respiration and energy aspects of photosynthesis. (CW)

Presents an experiment to demonstrate the degree to which environmental cations are taken up by susceptible lichen organisms in the field. Discusses the preparation of materials, procedures and typical results for this short laboratory exercise. (CW)

Describes a procedure for the growth of tobacco plants in flasks. Demonstrates plant tissue culture manipulation, totipotency, and plant regeneration in approximately 12 weeks. Discusses methods, materials, and expected results. (CW)
