Develops a simplified electrostatic model of the heart with conduction within the torso neglected to relate electrocardiogram patterns to the charge distribution within the myocardium. Suggests its application to explanation of Coulomb's law in general physics. (CC)

Presents results of a science clubs' investigation of the micro-meteorology of a shopping center, particularly temperature and precipitation effects related to automobile air pollution. (AL)

Describes a method for conducting a sophomore organic chemistry laboratory which included integrating projects with a writing task involving peer group interaction. Also includes background/theory, chemistry tasks, writing tasks, and evaluation. Included in appendices are an analytic worksheet and grading scale. (JN)

Describes a Malaysian school project which deals with tin, and extracting tin from its ore in the laboratory, as well as the economics involved and the locating and mining the ore. (HM)

Describes the Science in Social Context (SISCON) project. The use of the SISCON in the British colleges, polytechnics and secondary schools and a list of the units, of the course are included. (HM)

Using the example of a ten-year-old boy working on a science project, the author discusses the question of when and how much the teacher should intervene and direct a child's independent learning activity. (SJL)

Describes a high school project which integrates art and science by providing biology students with opportunities to exhibit student art work on biological subjects. (CS)

An experiment is described in which undergraduate students can optimize the relative yield of sec-butylbenzene by varying molar ratio and temperature. (Author/SA)

Discusses whether electronics should be included as a subject at school, and describes the process of developing an O-level electronics course which is based on electronic systems for British schools. The course content and structure are also included. (HM)

Describes the collection, care, and maintenance of protozoa by elementary school students. Techniques for collecting and observing them are given. (SA)

Presents a mini-environment project as a valuable teaching tool for presenting ecology. The procedures for setting up a mini-desert in the classroom are presented as a model. Basic components of the mini-environment project are also included. (HM)

Describes a school project on energy conservation, in which fifth and sixth grade students involved the town community in becoming aware of the extent of the energy shortage and considering modes of cutting down on energy usage. Included are ideas for projects and science fairs. (CS)
