This experiment, mixing solutions of potassium iodide and lead nitrate to give a bright yellow lead iodide precipitate, often leads students into other topics such as making paint from the precipitate. (BB)

Reviews development and first two years' experiences of a laboratory course of inquiry into the nature and processes of American civilization through examination of local history as symptomatic history. Faculty, graduate fellows, and advanced undergraduates collaborated on research and analysis of the relationship of culture, environment, and…

Three studies are described in which choice reaction time (RT) was related to such psychometric ability measures as verbal comprehension, numerical reasoning, hidden figures, and progressive matrices tests. Fairly consistent negative correlations were found between these tests and choice RT when high school samples were used. (Author/CTM)

Reviews the history, development, and current use of wind tunnels in aerospace research. (SL)

Described are a method of cultivating Euglena, a method for presenting and solving mole equations, and a design of a simple solar collector. (SL)

Presenting information intended to aid those who will be responsible for integrating the educable mentally retarded into shop programs, this article discusses population characteristics, physical characteristics, and learning characteristics of the mentally retarded. Interpersonal skills and safety considerations are also discussed in relation to…

Describes benefits and techniques for utilizing Mormoniella vitripennis (jewel wasps) in teaching biology. Feeding, courtship, egg-laying, and insect behavior investigations are presented. (SL)

This paper uses the Interpersonal Perception Method (IPM) to analyze a single episode in a group's experience. The authors feel that such an approach is much more useful than the more usual trait analysis in understanding those experiences which will mediate the group's functioning. (NG)

A precise method of determining absorption maxima where Gaussian functions occur is described. The method is based on a logarithmic transformation of the Gaussian equation and is suited for a mini-computer. (MR)

Provides a variety of science activities structured around the germination and growth of oak trees from acorns. (CP)

Reports on apparatus for generating Lissajous figures, projecting Poisson's spots, photographing diffraction patterns, electric heating, and projecting moving longitudinal waves on an oscilloscope. (SL)

Examines standard and unique student safety considerations and offers suggestions for maintaining a safe laboratory class environment. Topics discussed include general safety considerations, safety factors unique to various handicapping conditions, instructional considerations, assessing instruction, and developing safety conscious attitudes. (TA)

An experimental year of oral testing using the language laboratory at Victoria University is described. A new first-year 12-credit course is primarily a language course based on audiovisual/lingual methods. The content, evaluation, and administration of oral expression tests and performance tapes are covered. (SW)

Reviews six items of science equipment, including power supplies, timers, and a watt meter. (SL)

Describes the dubious successes of the "Learning Assistance Program" at a community college in British Columbia. Discusses present and future considerations for solving problems and attending to the educational needs of students in that geographical area. (RL)
