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…

Summarizes the results of a nutrition questionnaire administered to students in grades eight, nine, and 10 (N=490). Results suggest a need for nutrition education, particularly concerning the relationships between diet and health. (DS)

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)

This article presents the perceptions of nine past presidents of the National Association of Biology Teachers regarding the organization and its growth in the period covering 1966 to 1985. These comments were taken from taped statements which are now in the organization's archives. (CW)

Discussed is an activity designed to teach small mammal ecology and the scientific method using fluorescent dyes and pigments. Procedures for analyzing home ranges and social organizations are described. A list of 16 references is included. (CW)

Described is a project designed to determine the kinds and types of science laboratories located in and around Yolo County, California. Summarized are some of the sites visited by the investigator and some of the impressions of those facilities. (CW)

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)

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)

Glaring and basic textbook errors and misconceptions about photosynthesis are discussed. The Calvin Cycle, photosynthetic products, alternative cycles, and plants as producers are considered. Included are observations of both college and secondary textbooks. (CW)

Describes principals of physics that are manifested in simple biological systems of heat conservation structures. Outlines materials needed, data collection, analysis, and discussion questions for construction and operation of two models, one that is a countercurrent heat exchange model and one that is not. (RT)

Describes a high school biology course that utilizes the science-technology-society approach. The course developed from research findings that high school students are interested in learning about themselves--mainly their bodies. Evaluation of the program revealed that it was successful in accomplishing learning objectives. (PR)

Seniors often determine their college major based on academic strengths or interests in either the sciences or humanities. To judge the usefulness of rapid advances in our technological society, students need to gain a better understanding of all subjects. A program is described which is designed to help close the gap between those who study…

The National Science Education Standards (National Research Council [NRC], 1996) call for a greater emphasis on scientific inquiry in K-12 science classes. The Inquiry Standards recommend that students be engaged with scientific questions in which they collect and interpret data, give priority to evidence to construct explanations, test those…

Describes a course in life science for nurses designed to present information through 90 modules which extend over four 12-week terms. Each module is designed to be a self-contained, independent unit and focuses primarily on a single topic. (Author/PEB)
