The eventual conversion to the metric system and implications of this change are discussed. (CP)

Discusses the connection between intuition and man's senses, how the science of measurement has extended man's senses, and the close relationship of physics to the physical environment. (Author/CP)

Discusses continuing problems with universal adoption of an international system of units--particularly the confusion over weight and mass. Suggests a remedy to the situation. (CP)

Describes activities for helping students learn the metric system. Suggests teachers use metric units in ordinary conversation. Describes a homework assignment for students to make 20 metric measurements. Provides instructions on conducting a "TV studio" style game that is played on Metric Day (October 10th). (PR)

Introduces an activity in which students prove that milliliters and cubic centimeters are equal. Assigns students in groups for the activity and starts with a realistic story to increase student interest. (YDS)

The International System of Units (SI) or the metric system contains related units which make science simpler for students and teachers. By emphasizing descriptive units, requiring unit use throughout calculations, and using negative exponents, teachers can help students have a better understanding of energy, pressure, and mass concepts.

Discusses advantages of using the joule as the focus of a teaching strategy to unify the concept of energy. Includes applications to various energy forms and use of the joule in converting constants. A set of worked problems, using relationships discussed in the article, are available from the author. (JM)
