Describes four physics experiments including "Investigation of Box Resonances Using a Micro"; "A Direct Reading Wattmeter, DC or AC"; "Exercises in the Application of Ohm's Law"; and "Hysteresis on Gas Discharges." Discusses procedures, instrumentation, and analysis in each example. (CW)

Describes the use of a microcomputer-based laboratory (MBL) in teaching the concepts of heat and temperature to eighth grade students. Discusses the advantages of being able to instantly display the results of their experimentation with the use of temperature and light probes, and heat pulsors. (TW)

Contains abstracts of presented papers which deal with teaching materials and methods in physiology. Includes papers on preconceptual notions in physiology, somatosensory activity recorded in the dorsal root ganglion of the bull frog, and the use of the Apple Macintosh microcomputer in teaching human anatomy and physiology. (TW)

Discusses the importance of teaching about enzymes in chemistry. Mentions several applications of enzyme technology to other fields. Describes an experiment involving the immobilization of yeast cells as a biocatalyst for the ethanol production from glucose. Argues for more biotechnology to be integrated into basic chemistry courses. (TW)

Three assessments of the status of school science discovered that textbooks frequently determine course content, the preparation science provides for next academic level is its justification, lecture method is widely used, science is a low educational priority, and students feel it is irrelevant to later life experiences. (MBR)

Exploratorium Science Snacks are miniature versions of some of the most popular exhibits at the Exploratorium, San Francisco's (California) museum of science, art, and human perception. Nearly 100 teachers worked with Exploratorium staff members to create scaled-down versions of exhibits that teachers could make using common, inexpensive,…

Presents a critical review of laboratory adaptations for visually impaired students in general science, biology, chemistry, and physics over the past 30 years. Learning modes used by these students (since these are considered when making adaptations) and ways students benefit working independently in a science laboratory are discussed. (JN)

Presents activities, experiments, demonstrations, and equipment for physics instruction, including computer applications of sports biomechanics, vibrating magnetometer, alternative uses for an environmental comparator, CMOS integrated circuit logic tutor, and an activity demonstrating positive and negative leakage. (JN)

Describes the technical and pedagogical characteristics of the ESSOR system simulation on minicomputers, which allow the simulation of science experiments in the laboratory. Reflects on several years of use and development in the field of chemistry. (Author/DS)

K-12 students and teachers can use the Internet for planning science fair activities--for project ideas, resources, and interactive Web sites. Lists 26 science Web sites specializing in question answering, activities, experiments, optics, math, dissection, inventions, physics, space, genetics, cockroaches and worms, and Twinkies (sponge cakes).…

Described are several activities for teaching children to determine mass and volume. Included are the masses of a water drop and a grain of rice; the volume of a water drop and small solids; and measuring the width of a hair. Procedures and materials for the activities are discussed. (CW)

Describes two simple methods of error analysis: (1) combining errors in the measured quantities; and (2) calculating the error or uncertainty in the slope of a straight-line graph. Discusses significance of the error in the comparison of experimental results with some known value. (MDH)

Presents a framework for teachers to use the thermodynamic system of popping corn to generate student interest. Examines the popping mechanism and the role of steam in, the heat required during, and the energy efficiency of the popping process. (MDH)

Describes an activity measuring the amount of dissolved carbon dioxide in carbonated water at different temperatures. The amount of carbon dioxide is measured by the amount of dilute ammonia solution needed to produce a pH indicator color change. (PR)

Describes four instructional techniques used to deliver specific developmental objectives in both an introductory chemistry course and a general course in science and technology. The four techniques described are miniresearch projects, scenario-based research projects, short essay examination questions, and issues-directed research project. (PR)
