A monthly exchange of tips, projects, ideas and resources. (Editor)

This report introduces oceanographers to the International System of Units (SI) in physical oceanography. The SI constitutes a universal language, designed to be understood by all scientists. It facilitates their mutual comprehension and exchange of views and results of their work. The first part of the report is devoted to physical quantities,…

Ideas are presented for demonstrating the kilometer to school children. (BB)

Looks at what the problems are in the use of quantities and units in chemistry and what has been achieved until this time. Considers quantity and amount of substance, quotients of physical quantities, composition of mixed phases, and equations with quantities. Makes recommendations for future considerations. (CW)

Five rules for teaching the metric system are presented, and five measurement activities which can be adapted for elementary or secondary students are described. (DT)

Describes how to teach metrication in the classroom and home without spending a lot of money. The study should be on-going and not a unit of instruction on metrics. (Author/EB)

Teachers and administrators are encouraged to re-evaluate the instructional program as it relates to the teaching of measurement. Strongly suggests that the primary grades are where an intuitive feeling for units of measurement will take root. (Author/EB)

Describes some simple activities that teach the use of the metric system. (MLH)

Describes an out of the classroom activity encompassing science and mathematics concepts used in mapping and measuring tree heights. (BR)

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. (DH)

Describes a classroom activity which involved sixth grade students in a learning situation including making ice cream, safety procedures in a science laboratory, calibrating a thermometer, using metric units of volume and mass. (EB)

Presents an introductory activity in the use of arbitrary measuring units, using simple materials found in school or at home. Materials are listed and activities provided. (EB)

Describes construction of an inexpensive mini-balance and activities involving small weights and the metric system. (BR)

Reviews "Earthquakes and Volcanoes" (grades 3-6), "Metric Football" (a game), and "Happy Metrics I and II" (grades 4-6). Includes format, nature of activities, source, price, and reviewer's comments. (JN)

Information is provided on current metric practices accepted by the Standards Council of Canada. Rules and examples are given for using units, symbols, and numerals. A table of metric prefixes; a list of units, prefixes and symbols; and a summary of commonly used units are provided. Interrelationships among units are noted. Information on…
