Describes two experimental apparatus which may be used to demonstrate the skin effect phenomenon. One apparatus shows the decrease of a magnetic field as it penetrates a thickness of metal; the other demonstrates the decrease with depth of current in a wire. (Author/MLH)

Describes a set of student projects, each involving about 240 hours of laboratory time, covering the following topics: wind power monitoring, wind generator design, solar power, and the heat pump. (MLH)

Describes an experiment that uses anodic stripping voltammetry as an alternative to atomic absorption for quantitating lead and cadmium leached from pottery samples. (MLH)

Describes an organic-biological experiment that illustrates an important chemical commercial process and the use of microorganisms as chemical reagents. (MLH)

Describes an experiment in which the iodonation of aniline reaction is shown to undergo catalysis in solution of sodium lauryl sulfate which forms micelles with negatively charged pseudo surfaces. (MLH)

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)

Describes an advanced undergraduate experiment in which the stepwise stability constants of hi(II)-cysteine chelate are determined. (MLH)

Describes an experiment in which ph values serve as a basis for separating the acidic aspirin from phenacetin and caffeine on an ion-exchange column. (MLH)

Described is a physics experiment in which small bits of metal on a water surface will move towards, and away from an electrostatically charged rod. The explanation for the motion of the metal bits deals with their shape and the electrical force on the water surface. (SL)

Describes an advanced undergraduate laboratory experiment for studying thermionic emission. The cathode of a type 922 photodiode is used as an emitter over a temperature range from room temperature to 80 degrees centigrade; the thermionic emission current varies by a factor of 3000 over this temperature range. (MLH)

Discusses experience of teaching optical experiments with emphasis upon the student's design and construction of refracting and reflecting telescopes. Concludes that the student's interest and acquired knowledge are greatly enhanced through the use of realistic experiments. (CC)

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.
