Describes an optical cell, suitable for high-pressure studies between at least -130 and +150 degrees Celsius, which may be assembled for about $50. Discusses experimental demonstration of principles involved when using the apparatus, including effects of pressure on coordination of ions in solution and on reaction rates in solution. (JN)

Discusses various ways science can be taught using microcomputers, including simulations/games which allow large-scale or historic experiments to be replicated on a manageable scale in a brief time. Examples of several computer programs are also presented, including "Experiments in Human Physiology,""Health Awareness…

Describes an Applesoft Basic routine that converts numbers from scientific to standard notation. The program, which works with numbers of any size or sign, uses several string-related functions that are explained in the program description. The complete program listing is included. (JN)

Describes a test item bank developed by the Association for Medical School Departments of Biochemistry (Texas). Programs (written in Pascal) allow self-evaluation by interactive student access to questions randomly selected from a chosen category. Potential users of the system (having student, manager, and instructor modes) are invited to contact…

Discusses the Rugby clock as a source of project material, use of ZX81 for experimental science, computer dice analog, oil recovery from reservoirs, and computer simulation of Thompson's experiment for determining e/m for an electron. Activities/procedures are provided when applicable. Also presents questions (and answers) related to time-coded…

Describes four components of a packet of materials designed for small-group discussions on alphafetoprotein (AFP) screening for neural tube defects. Components consist of instructional guidelines for group leader, informational packet on AFP, list of specific discussion questions, and student evaluation form. Copies of these materials are…

A three-part questionnaire was used to assess degree of emphasis given to values education in college biology. In addition to demographic data, the questionnaire, mailed to 377 biologists (185 forms returned), included items focusing on the significance of ethical issues and when life-science related values are best introduced to students. (JN)

Discusses the current crisis in science education, focusing on declining physics enrollments and physics teacher shortages. Indicates that the present situation is the culmination of a long trend, interrupted only weakly in the sputnik era, and that the state of the economy may provide a new context for examining the issues. (JN)

Describes a procedure used to optimize instrument performance as taught in a fourth-year undergraduate instrumental analysis course. Gives rules for fixed and variable size simplex and discusses calculations. Also explains use of computer simulation of instruments as a tool in teaching the simplex technique. (JM)

Seven complete secondary/college level acid rain activities are provided. Activities include overview; background information and societal implications; major concepts; student objectives; vocabulary/material lists; procedures; instructional strategies; and questions/discussion and extension suggestions. Activities consider effects of acid rain on…

Aviation and space (aerospace education) is the study of aviation and space and its impact on society. Discusses the nature and scope of aviation and space education in general and basic education. Also considers typical programs and scope at the elementary, secondary, and higher educational levels. (JN)

Describes how to input and output through the game ports of the Atari microcomputer to control experiments and collect data in the science laboratory. Indicates that the simple techniques described are easily transferred to other microcomputers. (JN)

Discusses the role of history, philosophy, and social implications of scientific ideas and advances related to the physics curriculum, considering who should teach what, to whom, and when. Suggests that physics teachers should have a deep and abiding interest in the history, philosophy, and social implications of science and technology. (Author/JN)

Discusses ATP synthesis in mitochondria/chloroplasts and cause of an antipodal high tide. Also discusses a simple field experiment on regulation of osmotic potential by Salicornia (pioneer plant of estuarine sale marshes) and use of a key to identify British mosquito larvae. The latter includes procedures for collecting, recognizing, and finding…

Students develop and use actual instrumentation in this course which focuses on analog computers, digital electronics, computer interfacing, and online computer techniques. Includes a student handout on the design of a bridge amplifier unit. Mimeographed experiment directions are available from the authors. (SK)
