This description of microcomputer-based laboratories (MBL) for science focuses on experiments with a motion detector by non-science majors at Tufts University. Exercises had been used previously with sixth grade middle school students, indicting the effectiveness of MBL for students with a wide range of abilities. (Author/LRW)

Addresses the history and philosophy of accident prevention in chemistry laboratories. Presents the results of a statewide survey done in Colorado designed to investigate the etiology of academic chemistry laboratory accidents in institutions of higher education. Patterns of accident characteristics identified by the student are discussed. (TW)

Describes an experiment designed to introduce biochemistry students to the specificity of an analytical method which uses an enzyme to quantitate its substrate. Includes the use of toxicity charts together with the concept of the biological half-life of a drug. (TW)

Summarizes some of the contributions to society made by women who have received the Garvan Medal. Addresses accomplishments in nutrition, industry, biochemistry, government, and group research projects. Includes anecdotal descriptions of some of the women made by colleges, authors, and students. (TW)

Describes two classroom chemistry demonstrations which focus on the descriptive chemistry of bromine and iodine. Outlines the chemicals and equipment needed, experimental procedures, and discussion of one demonstration of the oxidation states of bromine and iodine, and another demonstration of the oxidation states of iodine. (TW)

Discusses the history of American science and science education, with particular emphasis on the development of scientific inquiry and experimentation. Focuses primarily on the activities of individuals in the 1800's, and the introduction of science into secondary schools and higher education institutions in the early 1900's. (TW)

Discusses the development of a student's ability to control experiments as an important aim of modern science curriculum materials. Argues that most curriculum developers offer only a simplistic method of controlling variables. Suggests ways to enhance the development of variable control within the framework of student experiments. (TW)

Describes a lesson in which fifth graders made observations of candles. Discusses the progress of the lesson and the necessity of instructing students in what and how to watch and measure. Stresses that this can be easily accomplished inexpensively with imagination. (CW)

Addresses the need for providing science education for all children throughout the years of compulsory school, including students with physical impairments. Describes several modifications of equipment that can enable students with visual and orthopedic handicaps to do science activities. Lists some special modules that have been developed for…

Reviews three computer software packages for chemistry education including "Osmosis and Diffusion" and "E.M.E. Titration Lab" for Apple II and "Simplex-V: An Interactive Computer Program for Experimental Optimization" for IBM PC. Summary ratings include ease of use, content, pedagogic value, student reaction, and…

Reviews a method for determining oxidation numbers in covalent compounds and balancing mixed organic-inorganic or purely organic systems. Points out ambiguities presented when adjacent atoms have small or zero electronegativity differences. Presents other limitations that arise when using electronegativity values. (CW)

Describes a two-session experiment designed to provide a good illustration of, and to improve student knowledge of, the Grignard reaction and nucleophilic substitution. Discusses the procedure, experimental considerations, and conclusion of this experiment. (CW)

Describes a set of activities designed to help students determine whether walking or running in the rain will keep you drier. Includes a range from simple to sophisticated formulas that attempt to consider a number of variables and some basic laws of physics in the calculations. (TW)

Discusses: (1) feature of videodisc technology which make it a versatile educational tool; (2) availability of videodiscs for teaching physics and astronomy; and (3) example of the ways these videodiscs can be used in instructional settings. Tables listing physics and astronomy videodiscs (title, author, source, cost, and abstract) are included.…

Presents information about primates, including definitions and examples. Includes the activities "Thumbless Relay" and "Face It," which relate attributes of primates. Includes a story about chimpanzees along with discussion questions about the story. Reproducible worksheets and a quiz are also provided. (TW)
