The article discusses curriculum design by the classroom teacher rather than large scale national projects imposed on the teacher; describes how a grass roots approach in constructing curriculum might be developed. (BR)

Describes how to teach about "heat" and suggests do's and don'ts concerning the terminology and ideas which surround the concept of heat, in order to avoid student confusion and misconception. (BR)

Presents a brief history of electrostatics, approaches problems presented by lightning, and describes some basic areas of research and application of electrostatics. (GS)

Outlines the construction, basic principles, calibration, and laboratory application of a device for the investigation of static charge phenomena. (GS)

Discusses the significance of the simple, inexpensive type of calculator as a tool in the classroom and the contribution of the more sophisticated type to the school science department. (GS)

Describes a device that simulates the scales and motions involved in the observer coordinate system. (GS)

Describes an easily-implemented experiment in which a moderately complex relation between dependent and independent variables is involved. (Author/GS)

Describes the application of simulation as a teaching tool which provides a means of understanding living organisms by representing only the essential aspects of selected biological processes which might not be readily visualized. (BR)

Describes liquid surface holograms including their application to medicine. Discusses interference and diffraction phenomena using sound wave scanning techniques. Compares focussing by zone plate to holographic image development. (GH)

Explains macroscopic properties of a number of systems as averaged-out behavior of numbers of particles. The approach is applied to a model of nuclear fission, rotational velocity in a galaxy, the nature of the rings of Saturn, oscillations of the earth, drops on a spider web, and the shape of ruined Meidum pyramid.
