Outlines an experimental course for non-science majors that concentrates on science-related community problems. Some of the topics explored by the students are explained. Five schools and 400 students are involved. (DS)

Using the biochemical record to class archaebacteria, eukaryotes, and eubacteria involves abstractions difficult for the concrete learner. Therefore, a method is provided in which students discover some basic tenets of biochemical classification and apply them in a "hands-on" classification problem. The method involves use of RNA…

Reported is a technique for chromosome staining that is simple, rapid, inexpensive, and requires little skill for success. (PB)

Presents a method which organizes concepts and relates different phenomena to a single model of ecology. Describes how this model is used to explain the overall significance of biological and ecological cycles and its usefulness in helping students to understand the various dangers to and remedies available for an ecosystem. (CS)

Red Bank Catholic High School (New Jersey) has initiated an innovative science club called BRIM (Biological Revolution and Its Implications on Man) to inform and involve student members in recent biomedical advances and to promote critical thinking about their social and ethical implications. Club operations and financing are discussed. (Author)

Antianxiety agents are discussed in terms of their effects on the brain and central nervous system. Formulas for some substances, commonly prescribed as sedatives, are given. Includes a discussion on the toxicity and side effects of the drugs. (SA)

Achievement scores of Israeli high school students using Biological Sciences Curriculum Study (BSCS) materials were shown to be significantly higher than those for students using another curriculum. (MLH)

Investigates effects of method of presentation and structure on secondary student's acquisition of knowledge and psychomotor skills in teaching use of the compound microscope. Psychomotor skills and knowledge acquisitions were both found to be directly related to high structure and separated presentations. (SL)

Described is an exercise which uses inexpensive and easy-to-make materials to demonstrate the basic fundamentals of heredity. Discusses two approaches using a hypothetical insert to demonstrate inheritance, mitosis, meiosis, and genotypic and phenotypic frequencies. (CW)

This paper includes a general account of the biology of the brine shrimp, instructions on how the organism may be cultured, the results of some experiments on the ecology and population biology of the species, and some suggestions for further studies. (Author/CW)

Presented is an exercise for high school students which illustrates the principle and practice of measuring energy flow through a community. Included are worksheets, instructions, a flow diagram, and a list of ecosystem parameters. (Author/CW)

Described is the construction and use of an osmometer that is low in cost, easy to make, and durable. Materials needed and procedures are outlined. Diagrams show an assembled instrument and individual parts. (RT)

Describes the contribution made to the quality of human life by the study of genetics. Presents a description of the current status of genetics education. Suggests changes in genetics education necessary to keep up with new developments. (39 references) (CW)
