Scientists and teachers have worked together to produce teaching materials for the Very Small Radio Telescope (VSRT), an easy-to-use, low-cost apparatus that can be used in multiple laboratory experiments in high school and university physics and astronomy classes. In this article, we describe the motivation for the VSRT and several of the…

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 a student investigation of a reverse flame in a atmosphere of methane that won second place in the physics division of the International Science and Engineering Fair. Includes a discussion of falling and fracturing behavior, specifically dealing with chimneys, trees, pencil point, stirring rods, and chalk. (BT)

Describes two experiments in physics, using the same inexpensive apparatus, that may be performed as projects by high ability secondary science students. (JR)

Described are five physics activities including two superconductor projects, synchronizing video camera movements, electrical analysis of a bicycle, and apparatus for the measurement of thermal conductivity. (YP)

Describes an advanced NMR project that can be done with a 60-MHz continuous-wave proton spectrometer. Points out the main purposes are to give students experience in second-order NMR analysis, the simplification of spectra by raising the frequency, and the effect of non-hydrogen nuclei on proton resonances. (MVL)

Examines the effect of solar radiation on colored shingles. Describes the experimental procedure, results, and discussion. Presents a picture of the experimental arrangement and three graphs of data measured at different dates. (YP)

Electrospinning has been used to create nanofibers for filtration devices, tissue engineering, and protective clothing. Although electrospinning is now widely studied, because of the expensive equipment required and the advanced nature of this topic, it is not commonly found in high school science labs. Through grants from the Ohio State…

In evaluating whether the laboratory guides for Project Physics and for PSSC are consistent with the goals of their designers in demonstrating the interplay between experiment and theory in the development of physics, a system was developed for analyzing physics laboratory investigations, and the laboratory activities in the "PSSC Physics…
