A science laboratory was developed for use by kindergarten through sixth-grade students. The operation of and the types of science activities used in this laboratory are described. (JN)

Described are embryology experiments demonstrating effects of lithium on the nervous system and the use of hypertonic salt solutions to produce exogastrulation in the eggs of Xenopus laevis. (SL)

This book provides opportunities for engaging students in scientific investigations, offering a hands-on approach that encourages students to understand science concepts, gives them ways to apply the concepts, and introduces and reinforces the skills they need to become independent investigators. The basic outline and objectives of each section of…

This teacher's guide is for the "Mind Over Matter" series, a neuroscience education series designed to encourage students in grades 5-9 to learn about the biological effects of drug abuse on the body and the brain. "Mind Over Matter" includes eight colorful, glossy magazines, each of which is devoted to a specific drug or drug…

Suggestions are provided for teaching a unit on bees to first-grade students. In addition to science content, students learn valuable citizenship and academic skills while engaged in such activities as honey-tasting, visiting an apiary (bee farm), and writing poetry. (Author/JN)

Describes the first Biology Olympics for high school teams which took place at Slippery Rock State College, Pennsylvania. Individual events are described as well as the visitation day program for nonparticipants. (SA)

A set of instructions for growing algae successfully in the classroom and maintaining the culture is provided. Aids for identification of freshwater organisms are suggested. (SA)

Describes a course in which pollutant health impacts are discussed in the context of unifying concepts such as threshold v nonthreshold responses. (CS)

Presents a practical problem to students in a junior-level thermodynamics course in which a human body regulates its own internal temperature. This problem can be utilized as well (with modification) in an introductory physics course for life science majors. (HM)

Described is a method for integrating electrical and mechanical events of the cardiac cycle by measuring systolic time intervals, which involves simultaneous recording of the ECG, a phonocardiogram, and the contour of the carotid pulse. Both resting and stress change data are provided as bases for class discussion. (CS)

Discusses alternative theories to evolutionism. Five theories are mentioned, but most attention is given to the steady state theory of species which the author considers the most suitable partner for Darwinism in O- and A-level biology courses in the United Kingdom. (HM)

A modification of the Ames test for detecting carcinogens and mutagens using a strain of bacteria is described. A suggestion is given for checking the correctness of procedures by using particular hair dyes which have been shown to be mutogenic. (Author/SA)

Describes the collection, care, and maintenance of protozoa by elementary school students. Techniques for collecting and observing them are given. (SA)

Presented is a hand model which can be used to compare and contrast mitosis and meiosis. Features and procedures of the technique are detailed. Limitations of the models are discussed. (CW)

The advantages and justifications for using small animals in human-oriented research are reviewed. Some of the pitfalls of extrapolating animal-derived data to humans are discussed. Several specific problems with animal experimentation are highlighted. (CW)
