Illustrated and described is a convection box for classroom use to stimulate concept development in elementary school children. Other equipment and apparatus that may be used in open-ended science activites are listed. (CS)

Organized by topic is a reading list for A- and S-level biology. Described are experiments for measuring rate of water uptake in a shoot; questions to aid students in designing experiments; rise of overhead projection to demonstrate osmosis and blood cell counting; and microbial manufacture of vinegar. (CS)

Discusses how holography can be used as part of undergraduate physics laboratories. The authors propose a single beam technique of holography, which will reduce the recording scheme as well as relax the isolation requirements. (HM)

The Laboratory of Comparative Human Cognition has found that, if cross-cultural psychology has mounted a challenge to developmental psychology, it is because it has forced recognition of the fact that no context of observation, including the laboratory, is culturally neutral. Settings for behavior are embedded in larger systems of social…

Presents the results of the evaluation of a self-paced freshman physics laboratory and its assessment procedures used in the first-year physics course at the University of Adelaide, South Australia. (HM)

Presents details of anodic stripping analysis (ASV) in college chemistry laboratory experiments. Provides block diagrams of the analyzer system, circuitry and power supplies of the automated stripping analyzer, and instructions for implementing microcomputer control of the ASV. (CS)

Describes the process of collecting and maintaining a culture of protozoa. Instructions are also given for constructing a micropipette for transfering small organisms. (SA)

Discusses general strategies and specific devices to motivate intermediate and advanced students to use the language laboratory frequently and efficiently. Suggests types of materials most effective for language laboratory use. (PMJ)

This experiment, in which students experiment on themselves, involves carrying out analytical methods for vitamin C using instrumental and "wet" techniques. (SA)

An 18-month study of an elementary school computer laboratory is discussed. (MK)

Focuses on rewards in scientific research. Discusses the social structure of science and its ability to inhibit creativity as ilustrated in the work, "The Act of Creation: Creative Processes in Science." This is related to accounts of the discovery of the chemical structure of DNA. (SA)

Describes and evaluates a learning center approach to economic education which involved secondary social studies students at the University of Texas, Austin. The subject of the learning center project was how to purchase and maintain an automobile. Findings indicated that the approach was successful and interesting to students. (Author/DB)

Describes an experiment in which an air table is used to measure the moment of inertia of air pucks with various radii and mass loadings. (BT)

Divides the stated aims of practical work, listed in some of the A-level syllabuses of the GCE examining boards, into four groups and discusses each: didactic aims, the development of skills, the scientific method, and affective aims. (GA)

Gives a brief description of open-circuit wind tunnels of rectangular cross-section and of how expanded polystyrene can be used to build a small one. (Author/GA)
