Peer reviewedPinkney, J. N.; And Others – School Science Review, 1976
Describes eleven laboratory experiments, including the catalytic effect of copper in zinc-acid reaction; a study of the rate of polymerization of some aldehydes; and a demonstration automatic potentiometric titrator. (MLH)
Descriptors: Chemical Reactions, Chemistry, College Science, Higher Education
Peer reviewedSeymour, Raymond B.; Stahl, G. Allan – Journal of Chemical Education, 1976
Describes a laboratory procedure for separating a mixture of plastics representative of scrap plastic using various solvents and solubility techniques. (MLH)
Descriptors: Chemistry, College Science, Higher Education, Instructional Materials
Peer reviewedBlackburn, James A.; Koenig, R. – American Journal of Physics, 1976
Described is a simple apparatus to determine acceleration due to gravity. It utilizes direct contact switches in lieu of conventional photocells to time the fall of a ball bearing. Accuracies to better than one part in a thousand were obtained. (SL)
Descriptors: College Science, Higher Education, Laboratory Equipment, Laboratory Procedures
Peer reviewedLally, Dale, Jr. – NALLD Journal, 1976
The construction, equipment, and operation of a new language laboratory facility at the University of Louisville is described. (RM)
Descriptors: Audiovisual Centers, Filmstrips, Laboratory Equipment, Language Instruction
Peer reviewedDeanhardt, M. Lynn; And Others – Journal of Chemical Education, 1977
Describes an experiment that uses anodic stripping voltammetry as an alternative to atomic absorption for quantitating lead and cadmium leached from pottery samples. (MLH)
Descriptors: Chemical Analysis, Chemistry, College Science, Higher Education
Sturges, A. W.; Grobe, Cary H. – Improving College and University Teaching, 1976
The audio-tutorial method of instruction has been used in a freshman biology course at the University of North Dakota since 1966. It seems to be as effective as the conventional method, if achievement is the only consideration, but more significant if other implications are assessed. (LBH)
Descriptors: Audio Equipment, College Freshmen, Higher Education, Independent Study
Peer reviewedDeAngelis, Thomas P.; Heineman, William R. – Journal of Chemical Education, 1976
Describes a unified experiment in which an optically transparent thin layer electrode is used to illustrate the techniques of thin layer electrochemistry, cyclic voltammetry, controlled potential coulometry, and spectroelectrochemistry. (MLH)
Descriptors: Chemistry, College Science, Electricity, Higher Education

Peer reviewedGoh, S. H. – Journal of Chemical Education, 1973
Descriptors: Chemical Reactions, Chemistry, College Science, Instructional Materials
Peer reviewedKakis, Frederic J.; Rossi, Carl J. – Journal of College Science Teaching, 1974
Describes an experiment designed to provide the opportunity for studying some of the parameters affecting the stability of Vitamin C in various environments, and to acquaint the student with an experimental procedure for studying simple reaction kinetics and the calculations of specific rate constants. (Author/JR)
Descriptors: Chemical Reactions, Chemistry, College Science, Laboratory Experiments
Peer reviewedCarlson, Gary D.; Black, Wayne E. – Environmental Science and Technology, 1973
An atomic absorption spectrophotometric method is described for the rapid analysis of lead dioxide candles exposed to ambient air containing sulfurous pollutants. (Editor/JR)
Descriptors: Air Pollution, Chemical Analysis, Environment, Environmental Education
Peer reviewedWard, Alan – Science Activities, 1973
Several simple experiments using easily obtained materials are described which illustrate some of the properties of light (travels in straight lines, reflection, and refraction). (JR)
Descriptors: Instruction, Laboratory Equipment, Laboratory Techniques, Light
Peer reviewedMyers, Thomas M. – NALLD Journal, 1973
Discusses, outlines, and illustrates problems and methods of portable, magnetic-tape, cassette-recorder maintenance. (RL&)
