Classifies errors as either systematic or blunder and uncertainties as either systematic or random. Discusses use of error/uncertainty analysis in direct/indirect measurement, describing the process of planning experiments to ensure lowest possible uncertainty. Also considers appropriate level of error analysis for high school physics students'…

Discusses indoor air pollution in general and formaldehyde in particular, citing major sources of formaldehyde in home building materials and home furnishings. Also describes a laboratory procedure necessary to test for formaldehyde levels in the air and in materials. Includes list of equipment required. (JM)

Science curricula typically do not capitalize on the hands-on, self-initiated learning style of young children. This book provides a comprehensive, developmentally appropriate approach to science education with young children, with special attention to physics and chemistry. The book's introductory chapter is followed by chapters on: (1) science…

The Health Sciences and Technology Academy (HSTA), administered through West Virginia University, provides professional development to science teachers who partner with higher education faculty in a science and math enrichment program for financially disadvantaged African American students. This program focuses on human nutrition and has…

Laboratory experiences as a part of most U.S. high school science curricula have been taken for granted for decades, but they have rarely been carefully examined. What do they contribute to science learning? What can they contribute to science learning? What is the current status of labs in our nation s high schools as a context for learning…

Presents procedures, experiments, demonstrations, teaching suggestions, and information on a variety of chemistry topics including, for example, inert gases, light-induced reactions, calculators, identification of substituted acetophenones, the elements, analysis of copper minerals, extraction of metallic strontium, equilibrium, halogens, and…

Fourteen papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982) are summarized. Papers focused on secondary/college chemistry courses, programs, instructional strategies, and projects emphasizing the relationship of chemistry to "real world" problems and issues. (JN)

Forty-five "poster session" papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982) are highlighted. These papers focused on computers in chemistry and chemical education (emphasizing programs) and on instructional innovations (including courses, teaching methods, testing, experiments, and others). (JN)

Describes a two-semester laboratory program designed to motivate students. The program consists of computer-oriented modules and discovery approach laboratory exercises. Students complete similar computer/laboratory material during the first semester but elect one of three tracks during the second semester (computer, every-day life, and…

Describes three methods for offering practical work for external science courses: residential sessions on campus, local centers, and use of home laboratory kits. The advantages and disadvantages of each are discussed and examples of each in operation are given. A 21-item bibliography is provided. (EAO)

Microcomputer-based instrumentation packages enable computers to collect continuous analog data, convert data to digital form for processing, and display results on monitor. Discusses classroom advantages of these packages, describes one package for teaching harmonic motion, and provides a list of currently available packages (including vendor and…

A shoe box is converted into a model home to demonstrate the energy efficiency of various insulation measures. Included are instructions for constructing the model home from a shoe box, insulating the shoe box, several activities involving different insulation measures, extensions of the experiment, and post-lab discussion topics. (DS)

Outlines a variety of laboratory procedures, demonstrations, and classroom materials including a three dimensional, moveable cardboard model of the rib cage and diaphragm; a polyphenal oxidase experiment; ringing experiment using Impatiens; enzyme rummy game; and leaf impressions. (DS)

Suggestions are given for encouraging parents to participate in their children's science studies, at home and at school. Several sample lessons illustrate the kinds of experiments that require only inexpensive supplies which parents can provide. (SA)

Describes an experimental setup which allows the student to investigate the resonance characteristics of a vibrating plate using a small, circular steel plate clamped around its perpiphery. (HM)
