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)

Presents International Standard (SI) units for the field of electrochemistry and magnetochemistry. (SL)

Provides criteria for elementary teachers for selecting materials for metric education. Some teaching aids and equipment lists are suggested that can be helpful to the classroom teacher. (SA)

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…

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)

Authors have found that students have experience with metric units for volume and length; however, students have difficulty conceptualizing mass measurements in terms of grams and kilograms. Presents an activity, "Mass Appeal," where students use an equal arm balance to become familiar with the gram. (PR)

Presents an activity on metrics for elementary children which utilizes newspaper comic strips. Children are asked to write humorous metric captions to match the pictures. (SA)

Compares the effectiveness of three instructional modes for teaching metric knowledge and raising the level of positive metric attitudes of preservice elementary teachers who include both high and low mathematics achievers. Similar gain scores and attitudes resulted from the three randomly assigned treatment groups of preservice teachers (N=141).…

These materials were designed to be used by life science students for instruction in the application of physical theory to ecosystem operation. Most modules contain computer programs which are built around a particular application of a physical process. The module is concerned with conventional techniques such as concepts of measurement,…

Presents an activity integrating mathematics and science intended to introduce students to the use of metric measurement of mass as a way to increase the meaningfulness of observations about variables in life sciences. Involves measuring the nutrient tolerance of algae. Contains a reproducible algae nutrient graph. (Author/MKR)

Presents the following activities for teaching elementary students about the metric system: Metric Soda Fountain, Metric Meals, Metric Moola, and Metric Golf. (PR)

Seventh-grade students (n=397) were studied to determine the effect on immediate achievement and retention of a unit designed to promote the development of estimating skills involved in metric measuring. Identical metric instruction was used with the exception of activities in estimation for the treatment group. The treatment group retained…

Describes how students in grades 2-8 can make beakers from quart-sized oil containers and calibrate them in milliliters. In an second activity, students estimate the volume of water in four jars and use their beakers to measure the water in each. The estimates are compared to the true measurements. (PR)

Presents two multiple-lesson activities that integrate science and mathematics. Lessons involve hands-on activities for grades 4-5 to develop the notion of average around building a racer; and accurately estimating and measuring crystal growth in grades 8-12. (MDH)

This profusely illustrated activity book helps students understand systems and cycles, how years change the look of the Earth, and how students can protect resources. The sections (and activities) in this book are: (1) The Earth (Introduction--View, Soil & Dirt); (2) Forces (Plate Tectonics, Earthquakes, Mountain Building, Erosion, Volcanoes,…
