Describes modules designed to enable a student to learn a measurement technique and familiarize himself with measurement instrumentation independently of a laboratory course. Presents an example of a module involving the measurement of electrical resistance and lists other modules that have been developed. (GS)

Describes a combined demonstration and student experiment course to illustrate fundamental techniques, instrumentation, and concise report writing. Describes experiments including tensile tests, heat treatment, equilibrium diagram, microexamination, strain measurement, and recrystallization. (GH)

Describes some of the advantages of having the science teacher develop, use, maintain, and troubleshoot the new instructional materials. (GA)

Describes a device for maintaining the proper water level in knife boats during ultramicrotomy. Water levels in troughs are adjusted rapidly and precisely during the cutting process. Illustrations are included. (Author/MA)

The construction of an operational amplifier for use in a chemical instrumentation course is described. (CP)

Examines the major factors shaping the field of physical chemistry with special attention to instrumentation, computers and lasers. (Author/GA)

Describes a two-term course in electronic instrumentation for chemistry and physics students. The first term focuses on analog circuits and the measurement of voltage, current, and impendance. The second-term course focuses on digital pulses/logic, microcomputer organization, and assembly language programing and interfacing to experiments. (JN)

Discusses various topics related to the interfacing of computers, focusing particularly on methods of data collection using instruments. Topics include serial digital connections (examining RS 232C and V.24, physical protocol, electrical protocol, and other areas) and parallel digital connections. (JN)

Presents three ideas to help hold costs down in purchasing and using science equipment. These include (1) use of pencils and other graphite rods as sensors in potentiometric titrations, (2) rubber bulb modification for pipetting, and (3) a heater for a glassware bath. (JM)

Describes a modular approach to help select the most effective instruments for particular applications. In the approach, an instrument is considered to be a system composed of modules, each module performing a particular function. General input/output functions of various modules, how they modify signals, and module sensitivity are discussed. (JM)

Presents an inorganic oxidation-reduction kinetics experiment, and describes a low cost (less than $50) modification of the Bausch and Lomb Spectronic 20 Colorimeter which will provide a linear output in absorbance. (MLH)

Describes the construction and application of two new types of detectors that use the discharge provoked in a gas by the passage of a charged particle as the means of detection. (MLH)
