This booklet contains a programmed lesson on the properties of sea water. It is designed to allow students to progress through the subject matter at their own speed. Since it is written in linear format, it is suggested that students proceed through the program from "frame" to succeeding "frame." Instructions for the students and a list of lesson…

Briefly describes a physics course for nonmajors which focuses on light and color. (PEB)

Directions are given for student learning activities on illusions, shadows, the spectrum, and colors. (DT)

According to a recent government survey, employment in privately-owned atomic energy facilities now exceeds employment in government facilities. In this field, engineers, scientists, technicians, and craft workers account for the highest proportion of total employment. (MW)

Wayland Academy in Beaver Dam, Wisconsin, has an award-winning science center that defines three main categories of science -- physics, chemistry, and biology. (Author/MLF)

Reports the results of an investigation in which the attitudes of Israeli high school students to physics were studied in an attempt to identify variables that may account for the low enrollment in this subject. (JR)

A survey of the information use and communication patterns of physicists. Includes tables on: sources of information; journal use, importance, and subscriptions; preferred study areas; and library use. (LS)

Presented are analytical abstracts, prepared by science educators, of fourteen research reports. The abstracts are grouped in three clusters: teacher characteristics and behaviors, student characteristics and behaviors, and instruction. Each abstract includes bibliographical data, research design and procedure, purpose, research rationale, and an…

Describes a lecture demonstration that has been effective in teaching the concept of the lack of simultaneity in introductory physics courses. The demonstration experiment can be used for studying the relationship between simultaneity and causality and as a conceptual device for analyzing the lack of simultaneity in special relativity thought…

Explains efficiency in terms of thermodynamics, and states specific ways in which energy efficiency can be increased in the following areas: automobiles, industrial processes, and indoor use in the home. (MLH)

Presents a series of calculations, appropriate for the freshman level, to determine the flow of electrons to oxygen along the electron transport chain. States that living organisms resemble fuel cells and develops calculations for determining power output. (GS)

Reports on a proposal for intensive study of a system for producing reactor fuel and electricity from repeated underground detonations of thermonuclear explosions. (Author/GS)

Particular concern at the slow pace with which the United States is making use of domestic energy technology, specifically nuclear power, is discussed with specific emphasis on a liquid metal fast breeder demonstration plant under consideration. (EB)
