Describes a one-year program in which students are given lectures on instrumentation topics, acquire experience participating in campus and community laboratories, and complete individual projects to receive the master's degree. Indicates a high ability of attacking laboratory problems in students' achievement. (CC)

Describes the pedagogical use of a 12.0m x 1.0m x 0.8m electromagnet to demonstrate the properties of magnetostatic fields and the Faraday-Henry induction law. (CC)

Author discusses science discovery lessons, presents a model of one, and offers suggestions for structuring other specific lessons. (Editor/MB)

Examines backward chaining, a method of producing demonstration films in which sequential steps in a procedure are taught backwards; that is, the last step is taught first, then the next to the last step, and so on. A film designed to teach procedures used in a science experiment is used as an example. (JJD)

Provided are 10 papers presented during a symposium on teaching cardiovascular physiology outside the lecture hall. Topics addressed include a mechanical model of the cardiovascular system for effective teaching, separate course for experiments in cardiovascular physiology, selective laboratory (alternative to cookbook experiments), cardiovascular…

The shore crab (Carcinus maenas) is an excellent subject for school study, both in the field and the laboratory. It is easily collected and maintained and can be used for a wide range of investigations. Some background details are given and possible areas of investigation suggested. (Author)

Describes equipment and procedures for an experiment using diodes to introduce non-linear electronic devices in a freshman physics laboratory. The experiment involves calculation and plotting of the characteristic-curve and load-line to predict the operating point and compare prediction to experimentally determined values. Background information…

Describes a simple apparatus and provides instructions to do relative index of refraction measurements/calculations and to show mathematical relationships betwen indices when light travels from one liquid to another. A listing of a computer program (in BASIC) which will analyze data is available from the author. (JM)

Presented are procedures for demonstrating the production of color oscillations when nitric acid is added to a formic acid/concentrated sulfuric acid mixture. Because of safety considerations, "Super-8" home movie of the color changes was found to be satisfactory for demonstration purposes. (JN)

Discusses a supplement to the "water to rose" demonstration in which a pink color is produced. Also discusses blood buffer demonstrations, including hydrolysis of sodium bicarbonate, simulated blood buffer, metabolic acidosis, natural compensation of metabolic acidosis, metabolic alkalosis, acidosis treatment, and alkalosis treatment. Procedures…

A two-stage synthesis of 4,6,8-trimethylazulene was developed for use in the undergraduate experiment, highlighting concepts not usually covered in the laboratory. The experiment requires purification procedures of chromatography and of sublimation and illustrates concepts of aromaticity, molecular orbital theory, and carbodium ion reactivity. (JN)
