Discusses the hydrodynamic reasons why a riverbed meanders through a plain. Describes how water movement at a bend in a river causes erosion and changes in the riverbed. Provides a mathematical model to explain the periodic shape of meanders of a river in a plain. (MDH)

This document contains a series of six modules which illustrate selected concepts of mechanics with hands-on activities and audiovisual materials. Following the modules is a collection of readings which give detailed explanations of the concepts presented in the activities. A guide for teachers and workshop leaders is provided for use in planning…

Discusses three topics related to physics: (1) the center of mass of a long stick thrown horizontally; (2) how electric current flows in metals; and (3) the theory of relativity in relationship with fictionalized time machines. (MDH)

Guided by Piaget's constructivist theory on how children learn, this book explores an innovative approach to teaching physical knowledge in preschool. Part 1 differentiates between "science education" and "physical-knowledge" activities, noting that physical-knowledge activities involve primarily movements of objects and changes in objects. This…

Reports on the results of an eighth grade student's experiments, conducted with a moving car, concerning the aerodynamics of a baseball in flight. Describes the peculiar diving ability of the split-fingered fastball, as well as the dancing and weaving effect of the knuckleball. (JJK)

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…

This high school physics resource is a simulator for optics, electronics, force, motion, and sound. Students can study oscillations, look at sound waves, and use probes to graph a wide variety of quantities. Over 100 activities are pre-written, and students can easily create their own additional activities using the multimedia editor. (WRM)

The study and use of kites have contributed to science through the development of aeronautics. This document traces some of the history of kites and provides teachers and students with basic information about kite components and flight dynamics. The major portion of the book provides students with 18 projects which deal with: (1) shapes that will…

Energy is a vital topic. Energy costs have risen dramatically during the last decade and home owners are concerned about their energy bills and the costs associated with heating or cooling their homes. An understanding of energy, its sources and ways to reduce its use or improve the efficiency with which people use it will become more important as…

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:…
