Discusses the use of a balance assembled from standard laboratory components to conduct an experiment on the repulsion between two bar magnets. Includes an analysis of data on the two-pole and four-pole models. (CC)

Limitations of classical mechanics in understanding molecular properties are discussed. Modifications introduced by quantum mechanics enable the instructor to include and integrate important concepts from thermodynamics, quantum mechanics, spectroscopy, and statistics. (DF)

Study compared patterns of teachers' verbal explanations of physics problems with patterns of scientific explanations evident in philosophical literature. Fourteen high school physics teachers were observed in micro-teaching situations and all verbal utterances analyzed. Results showed that constructs and lecturing are the most frequently used…

A description of the film loop laboratory system as an attempt to increase the desirability, flexibility, and efficiency of physics experiments for non-science students. (Author)

Discusses the historical rod contraction-block retardation (RC-CR) ether theory to illustrate its relationship to the special theory of relativity and the possibility of experimental differences between them. Indicates that the RC-CR theory is worthy of the attention of both physicists and science philosophers. (CC)

Suggests that the story of Professor Blondlot could be used to underline the nature of the scientific method. Blondlot claimed to have discovered N-rays in 1903, and was subsequently supported by many French scientists. Scientists from other countries were unable to verify his experiments and thus discredited his claim. (JR)

Describes the measurement of electric potentials by means of a flame probe. This method is used extensively in the new Nuffield Advanced Level Physics course, and provides a means of taking reliable quantitative results in an area of most school courses where the majority of the work is qualitative. (JR)

Describes the science program in a high school characterized by the combined study of mathematics and physics. Topics in two subjects are planned to apply knowledge in the other subject simultaneously. Curriculum planning, scheduling and other planning aspects are discussed. Students enjoyed the program and considered it useful. (PS)

Explains vast applications of simple harmonic motion in many fields of physics. With examples of 16 phenomena governed by the law, the author points out in conclusion that phenomena which may look like simple harmonic motion may not be in reality. (PS)

Describes a course based on three levels of student performance (achievement, rationalization, creative). Students work on the achievement level at their own rates with lectures available, but not mandatory. Laboratory exercises are required. Grading is dependent on the amount of fulfillment of all three levels. Year-end assessment was determined…
