Describes an apparatus that can be used to measure low gas pressures over a range of temperature in the undergraduate teaching laboratory. Discusses an experimental procedure and theory for pressure temperature measurements with this apparatus. (CW)

Discusses some contributions chemists can make in the investigation of crime. Describes the optical properties of materials and defines the refractive index. Explains the refractive indices for liquids and for solids, and provides laboratory exercises for determining both. (TW)

Traces the development of instruments used in spectrophotometry. Discusses how spectrophotometric measurements are made. Describes the color comparator, the filter photometer, and the spectrophotometer. Outlines the evolution of optical systems, including light sources, the monochromator, the photodetector, double-beam optics, and split-beam…

The impact of robotics in education is discussed in terms of academic assistance to industry in robotics as well as academic problems in handling the demands put upon it. Some potential solutions that can have lasting impact on educational systems are proposed. (JN)

Described is the construction of a density gradient column and several density related experiments which can be performed with the device. (SL)

In more than 90 percent of the American colleges the prevailing method of transfer from secondary school to college is by certification, based on the pupil's record in secondary school. In the large majority of cases a record of graduation from an accredited secondary school is required to every student admitted to college. When it is considered…

A physics program within which students design their own experiments and construct the needed equipment is described. Different projects and equipment designed and built by the students are detailed as examples of the success of this program. (JP)

A federal audit which began in June 1982 and should be completed by November is being conducted to determine possible extravagance, misuse, waste, fraud and abuse of laboratory equipment purchased on federal contracts and grants. A list of waste and abuse found mostly at industrial labs is included. (JN)

Describes and evaluates the fabrication of an easily constructed and inexpensive stop-flow system using commercially available components. (CS)

Describes a method to detect the presence of microgram quantities of nearly any metal in samples of alloys, minerals, water, and air. This chemical-spot testing technique requires no elaborate equipment and can be done by an amateur. (SK)

Describes ideas used to introduce the Australian Science Education Project (ASEP) for the students of Henley High School in Australia by helping students to gain access to lab equipment, facilities and manuals with a minimum of teacher direction. (HM)

Describes simple modifications that will permit external triggering of certain electronic timers, thus allowing their use in experiments which require greater precision than was possible with inexpensive apparatus. (GA)

The revolution in electronics is discussed as it applies to instructional potential in the school science laboratory. Electronic instruction (instrumentation) is included. (SA)

This paper, presented at the conference on the role of the laboratory in physics education which was held in Oxford, England in July 1978, describes how a Malaysian University has presented electronics and the laboratory work as a forced component in physics curriculum. (HM)

This experiment is intended as a classroom demonstration. It describes the preparation of materials, the procedure, and a few remarks related to demonstrating travelling waves of chemical activity in the Zaikin-Zhabotinskii-Winfree Reagent. (SA)
