Provides a survey and a review of earthquake activity and global tectonics from the advancement of the theory of continental drift to the present. Topics include: an identification of the major seismic regions of the earth, seismic measurement techniques, seismic design criteria for buildings, and the prediction of earthquakes. (BT)

Describes a learning project in analytical chemistry in which students are required to select instruments from the manufacturers' literature that would be suitable for a given analytical problem. Several examples are given. (SA)

A description is presented of a semantic differential instrument which evaluates attitude changes. Results are given from the testing of a twenty-five bipolar adjective scale intended to identify descriptors of nutrition education. (Author/SA)

Surveys the state of commerical development of analytical instrumentation as reflected by the Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy. Includes optical spectroscopy, liquid chromatography, magnetic spectrometers, and x-ray. (Author/MA)

Describes two variations of an air sampler and analyzer that are inexpensive to construct, easy to operate, and designed to be used in an educational program. Variations use vacuum cleaners and aquarium pumps, and white facial tissues serve as filters. Samples of air pollution obtained by this method may be used from early grade school to advanced…

Some of the important modern developments of thin-layer chromatography are introduced. Discussed are the theory and instrumentation of thin-layer chromatography including multidimensional and multimodal techniques. Lists 53 references. (CW)

Describes the function of the various parts of the microscope and their integration in the formation of an optical image. Presents a procedure for setting up a microscope to obtain maximum resolution and contrast for each objective lens at all magnifications. (JRH)

Investigates the effect of movement instruction on beginning instrumentalists' steady beat perception, synchronization, and performance. Finds that a group receiving movement instruction did not perform significantly better than a control group at perception but did perform significantly better at synchronization and performance. Notes low,…

A comparison of 22 students in a traditional curriculum and 70 in a curriculum using speech science instrumentation demonstrated that opportunities to experience research improved attitudes toward and comfort with the research process. Findings support early introduction of scientific method into the communication disorders curriculum. (SK)

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

Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)
