Explores the power transfer using (1) a simple electric circuit consisting of a power source with internal resistance; (2) two different mechanical systems (gravity driven and constant force driven); (3) ecological examples; and (4) a linear motor. (YP)

Reports various misconceptions of Newton's third law obtained from interviews and written tests of high school students. Suggests putting emphasis on the third law in physics teaching. Ten references are listed. (YP)

Illustrated is the confusion over centrifugal force in sample problems, diagrams, formulas, and examples. Some recommendations to remedy the situation are suggested. (YP)

Technology for Science is a National Science Foundation funded program that is developing and testing curriculum units for teacher materials built around a series of design-oriented science problems called "challenges," mainly for ninth-grade general and physical science classes. Technology for science challenges have a clear connection…

This document is designed to provide practical information for teaching the Science 20-30 Program of Studies. The first section provides an overview of Science 20, explaining the program philosophy as well as clearly demonstrating how the program articulates with the junior and senior high science courses. The use of concept connections and…

Described is a graduate level engineering course offered at Princeton University in colloidal phenomena stressing the physical and dynamical side of colloid science. The course outline, reading list, and requirements are presented. (BT)

Discusses the orbit, motion, and phases of the moon. Describes three activities on the moon: "How Soon Can You See a Crescent Moon?"; "When is the Moon Visible?"; and "Lunar Eclipses." (YP)

Evaluates 10 courseware packages covering topics for introductory physics. Discusses the price; sub-topics; program type; interaction; possible hardware; time; calculus required; graphics; and comments on each program. Recommends two packages in projectile and circular motion, and three packages in statics and rotational dynamics. (YP)

This is the third book in a sequence of four volumes written and designed for parents of students of science, particularly for those at the lower and upper elementary and junior high or intermediate level, senior high students, college students preparing to teach science, and all those individuals who are interested in science and the application…

Presented in English and French, Physics 20-30 is an academic program that helps students better understand and apply fundamental concepts and skills. The major goals of the program are: (1) to develop in students an understanding of the interconnecting ideas and principles that transcend and unify the natural science disciplines; (2) to provide…

The purpose of this study was to investigate the effects of the 4MAT instructional system on achievement and attitudes in science. Fifty-four academically gifted sixth grade students in three schools in the Chapel Hill-Carrboro (North Carolina) City Schools were randomly assigned to two groups, a 4MAT group and a Restricted-Textbook group that…

Describes a first-year laboratory course designed to fulfill laboratory objectives of reinforcing lecture material, teaching experimental methodology, developing hands-on skills, and imparting a sense of error. The course's six segments examine: digital electronics with students building a photogate timer; error analysis; linear accelerated…

In 1990, the New Jersey Department of Education awarded the Randolph Township Board of Education a grant to evaluate the effectiveness of an existing technology learning activity called the "Magic Box", as part of the Teacher Developed Technology Education for the Nineties grant project. This document is comprised of three publications:…
