Described is a curriculum for a pathology class offered to eleventh and twelfth graders. Included are suggestions for laboratory activities and student projects. These activities can be incorporated into other science classes. (KR)

Discussed are facts about tort liability in science education and strategies that can be used to avoid liability. Variables such as maturity, size, age, mental capacity of students, and the nature of the activities are addressed. Included are four cases in which teachers were held liable for accidents. (KR)

Described is a simple circuit with which students can observe the effect of common dielectric materials in a capacitor and measure the dielectric constant of a piece of paper. Discussed are the theory, apparatus construction, and experimental procedures for this activity. (CW)

Defines and discusses jerk, the time rate of change of the acceleration. Presents some cases of jerk with mathematical expressions. Provides questions and problems for classroom use. Lists seven references. (YP)

Reports experiences during a two-year period in introducing the computer to the laboratory and students to the computer as a laboratory instrument. Describes a working philosophy, data acquisition system, and experiments. Summarizes the laboratory procedures of nine experiments, covering mechanics, heat, electromagnetism, and optics. (YP)

Reviews a software planetarium package called "Sky Travel." Includes two audiovisuals: "Conquest of Space" and "Windows on Science: Earth Science"; and four books: "Small Energy Sources: Choices that Work,""Stonehenge Complete,""Uneasy Careers and Intimate Lives: Women in Science…

Reports on acquiring and analyzing enzyme kinetics data using Apple microcomputers. Describes the experimental background and procedures, instrumentation, cautions, and construction aids. Cites applications which illustrate the use of a computer in a laboratory exercise. (RT)

Discusses one approach to addressing lack of exposure to science for African American students, the Saturday Academy of Clark Atlanta University. Areas of interest are laboratory activities, hands-on science, and social engagement. Presents a review of related literature and a study of the program. Contains 16 references. (LZ)

Develops the idea of fractals through a laboratory activity that calculates the fractal dimension of ordinary white bread. Extends use of the fractal dimension to compare other complex structures as other breads and sponges. (MDH)

A phenomenological explanation of this effect is provided. Suggestions for the inclusion of pyroelectric effects into a unit on electrostatics are given. (CW)

Examines whether teachers' views about the nature of science and scientific inquiry are reflected in their choice and design of learning experiences (particularly laboratory activities) and, therefore, are significant influences on students' understanding of science. (SM)

Presents a laboratory experiment designed to help students understand the concept of diastolic blood pressure, the pressure during which the left ventricle of the heart is not contracting. Examines the effect of strenuous exercise on blood pressure. Includes materials needed, procedures, results, and discussion of the results. (MDH)

Presents examples of chemical education research that illustrate changes in focus, method, and direction over the past 50 years. Contains more than 50 references. (WRM)

Describes an interdisciplinary science laboratory course for non-majors that uses the history of science as a curricular guide. Profiles two sample projects that consider the importance of teachers to classroom dynamics and the institutional political context. (Author/WRM)

Contemporary theories of learning postulate one or at most a small number of different learning mechanisms. However, people are capable of mastering a given task through qualitatively different learning paths such as learning by instruction and learning by doing. We hypothesize that the knowledge acquired through such alternative paths differs…
