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

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

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)

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)

Describes the activities of the Physics Teachers Action Research Group in which college physics teachers work together in planning, revising, and evaluating student projects that foster greater conceptual understanding and address student misconceptions. Presents the details of a project in which students were asked to build an accelerometer. (JRH)

Describes the implementation and evaluation of a nondirected student research project that aimed at acquainting students with some of the procedures used by physicists in the real world. Outlines specific project designs used by the students. (JRH)

Describes student projects on applications of solar energy optics to home design. Project criterion (requiring sketches and detailed calculations of time rate of energy flow/production) is that half the heat for the heating season be taken from the solar resource; calculations must be based on meteorological data for a specific location. (JM)

Describes the reordering of a ninth-grade physics course that aimed at making core concepts clear to the students while at the same time developing students' skills and depth of understanding. Discusses its benefits and associated problems. (JRH)
