Discusses how to make and fly boomerangs. (BB)

Describes the construction and operation of a simple field mill to measure atmospheric electric fields. (Author/CP)

Describes construction of a variety of relatively inexpensive cameras for astronomical purposes. (CP)

Describes the construction of a demonstration to show optical activity of table syrup. (Author/CP)

Outlines and illustrates the Dartmouth approach to developing a science project. This problem-solving approach, promoted by the Thayer School of Engineering at Dartmouth College, helps teachers in guiding students in all phases of project work. (JRH)

Introduces the basics of radio astronomy and describes how to assemble several simple systems for receiving radio signals from the cosmos. Includes schematics, parts lists, working drawings, and contact information for radio astronomy suppliers. (11 references) (Author/JJK)

Describes a project designed to allow middle school students to learn some science concepts through application of science and mathematics lessons. (ZWH)

Describes an analog electronic simulator for the motion of an object projected horizontally in a vertical acceleration field. The device features adjustable values for the horizontal speeds and "gravity." Trajectories are displayed on an oscilloscope. (Author/CP)

Instructions are provided for the construction of 4.5 foot diameter planetarium shells. (CP)

Discusses the use of high school students to present physics demonstrations to first graders. (MKR)

Details construction of an inexpensive electronic auditory device in which the resistance in parallel with the device is inversely proportional to the frequency of sound produced. (CP)

Describes an experimental project on boomerangs designed for an undergraduate course in classical mechanics. The students designed and made their own boomerangs, devised their own procedures, and carried out suitable measurements. Presents some of their data and a simple analysis for the two-bladed boomerang. (Author/MLH)

The article provides an example of a project in physics concerning clocks in which gifted pupils engage in high-level problem solving while developing technical knowledge and appropriate scientific methodology. Drawings illustrate the principles taught by the project. (Author/DB)

Described are 15 events that take place during a physics olympics at a Michigan high school. These events are planned with the idea of involving the older students in designing and presenting projects to ninth graders, and involving the latter in a day of outdoor participation. (SA)

Described are several physics activities developed by a high school: research corner, exploring an invention, construction projects, archives report and archives update, short term research and design projects, essay contest, and special projects. (YP)
