The electrode is a lead dioxide-silver plated wire. Construction of the electrode is simple, straightforward, and provides valuable laboratory experience. (Author/BB)

Describes the results of a study on the use of computer-simulated chemistry experiments. Four different simulated experiments were compared with four comparable laboratory performed experiments. Concludes that simulation has better results and is a good teaching procedure. (GA)

Describes the apparatus used and the experiments performed by a blind student in a freshman analytical chemistry course. (GA)

Explains some experiments involving thermal methods of analysis for undergraduate chemistry laboratories. Some experiments are: (1) the determination of the density and degree of crystallinity of a polymer; and (2) the determination of the specific heat of a nonvolatile compound. (HM)

This manometer is a modification of a design reported previously. It contains simplifications in the design of the manometer itself and in the associated electrical circuit. The apparatus is useful in the study of gas-phase reaction kinetics. (BB)

Describes a blood coagulation test developed by two high school biology students. Although the test lacks some precision, results indicate that the technique is comparable to standard methods used in laboratories. (MA)

Describes an experiment for general chemistry students for analyzing bathroom cleansers. (SL)

Describes a laboratory exercise illustrating the use of the Cannizzaro reaction in synthesis, the production of commercial resin, and the importance of natural products in industrial chemistry. (SL)

Describes an experiment utilizing the Solvay synthesis of sodium hydrogen carbonate to teach students to organize and plan a synthesis procedure. (SL)

Reviews experiments performed in a mobile spectroscopy laboratory. (SL)

This experiment, mixing solutions of potassium iodide and lead nitrate to give a bright yellow lead iodide precipitate, often leads students into other topics such as making paint from the precipitate. (BB)

Reports on apparatus for generating Lissajous figures, projecting Poisson's spots, photographing diffraction patterns, electric heating, and projecting moving longitudinal waves on an oscilloscope. (SL)

Presents four science experiments for the junior high level relating to electric switches, a chemical card game, combustion energy, and chromatography. (SL)

Describes the use of an interactive computer terminal for introductory laboratory experiments. (SL)

Reports an experimental procedure for a course in physical organic chemistry to illustrate correlation between structure and reactivity. (SL)
