The purpose of this paper is to present five new devices that demonstrate a variety of flow phenomena in liquids and granular materials that exhibit fluid-like behavior. These devices complement and add on to a recent collection of demonstrations that was published in this journal. The devices are self-contained and portable, and can be utilized…

Physics students have traditionally prepared many kinds of reports-- laboratory, activity, project, and even book or article reports. Smartphones and YouTube videos are familiar cultural objects to current students, and our students use smartphone cameras to include photographs of apparatus, phenomena, hand-sketched figures, graphs, and…

The object on the right-hand side of Fig. 1 is the whistling mechanism of an old-fashioned tea kettle. This started me thinking about similar devices in which a thin blade of air strikes a sharp wedge and a resonator is used to pick out specific frequencies. This note tells how I went about using the frequency spectrum application on a smartphone…

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

Discusses a project in which college students equipped a house with three different types of solar energy collectors and two vertical axis windmills. (MLH)

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)

Describes the relationships a high school built with neighborhood industry, a national laboratory, a national museum, and a large university while trying to build a scale model of the original atomic pile. Provides suggestions for teachers. (MVL)

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 use of a faceted geodesic structure in place of the true spherical dome in the construction of an effective and modestly priced planetarium. Indicates that the construction can be undertaken as a student group project. (CC)

Describes the educational system and national preparations for the International Physics Olympiad of the Soviet Union and Romania. Suggests some recommendations for American education. (YP)
