Presents an online trivia game on laboratory safety. (YDS)

Described is an activity in which students calculate constant velocity using a tape cassette player. The objectives, procedures, graphing directions, and formulas and values needed for the calculations are included. (KR)

Described are the theory and operation of Van De Graaff generators. The experience of one group of people in the reconditioning and repair of their apparatus is discussed. (CW)

Described is an inorganic chemistry course based on the premise that a balanced understanding of inorganic chemistry requires knowledge of the experimental, theoretical, and technological aspects of the subject. A detailed description of lectures and laboratories is included. (KR)

Described is a laboratory experiment that can be used to investigate bacterial survival in soil or water as well as the study of genetic transfer via conjugation. Discussed are materials, laboratory procedures, typical results, and a list of six references. (CW)

Discussed are the needs and objectives that should be evolving in biology education to meet the needs of modern students. Stressed are the principles of curriculum integration, relevance, cultural fitness, and adaptation. Directions for educational reform are described. (CW)

Discusses the hypothesis that similarities may exist between laboratory research paradigms evoking elevated blood pressure during task performance by normal subjects and video display terminal (VDT) work done by data clerks and college students. Type A behavior and the development of coronary heart disease are discussed, and further research needs…

Described are the uses of a spreadsheet program to compute the free energy change associated with a reaction; to model acid/base equilibria; and to solve equilibrium constant expressions. Stressed are the advantages derived from having the spreadsheet perform the multiple, trivial calculations. (CW)

Describes an undergraduate research program for minority students. The program and eight objectives of the first course of the program, "Introduction to Research," are presented. Some strengths and weaknesses of the course are considered. (YP)

Developments in microscale chemistry which have occurred in the late 1980s are reviewed. Possible directions for the future concerning the uses of microscale chemistry in organic, general, and high school chemistry are suggested. Twenty-three references are listed. (CW)

Presented is a method of constructing a wide variety of molecular models from inexpensive, durable materials. Equipment, supplies, atomic sizes, bond lengths and bond angles, assembly, and painting are discussed. (CW)

Develops an exercise in which students use magnetic-profile data gathered in the South Pacific to test the Vine-Matthews-Morley hypothesis. Uses the Eltanin 19N and 20N profiles. Relates the exercise to 20 current geology texts. (MVL)

Proposes an approach to school laboratory experiences which leads to gradual acquisition of inquiry skills based on the idea of advance organizers. Presents a design which is context familiar and can serve as an introduction to scientific inquiry. Discusses student achievement, and teacher and student attitudes. (CW)

Describes two oscillating reactions: the Briggs-Raucher reaction using H202, KIO3, malonic acid, and MnSO4 which changes from yellow to blue, and the Belousov-Zhabotinskii reaction uses NaBrO3, NaBr, malonic acid, and ferroin solution and changes from red to blue. Includes a third color demonstration on the six oxidation states of manganese. (MVL)

Argues that the writing program administrator's role of developing and maintaining a program that embodies and tests theoretical principles is a scholarly activity and should be recognized as such. Claims that the traditional disciplinary view restricting scholarship to written publication must be broadened. (RS)
