A known but often overlooked property of optical monochromators is discussed in view of its current applications. It is shown that grating and prism monochromators hold on to light for time durations proportional to resolving power and that the dispersing ability of monochromators extends to pulses of arbitrarily short duration.

Describes various uses for balloons in chemistry instruction, such as their use as stirring devices, gas reservoirs, sources of carbon dioxide, and as atomic models. (CS)

Describes how a sulfate-iodide "clock reaction" experiment can be used to emphasize the importance of observations and hypotheses in revealing cause-effect relationships. Investigative steps, theory, experimental principle, procedure, and the experiment report are discussed. (CS)

Reviews characteristics of coordination chemistry, the study of coordination compounds, a major focal point for the inorganic chemist. Provides a brief history regarding the Wernerian System and background information in modern coordination theory. (CS)

Discusses the concept of equilibrium in chemical systems, particularly in relation to predicting the position of equilibrium, predicting spontaneity of a reaction, quantitative applications of the equilibrium constant, heterogeneous equilibrium, determination of the solubility product constant, common-ion effect, and dissolution of precipitates.…

Discusses activities involved in a six-hour workshop program on creativity. Also describes: (1) sources of background information on creativity; (2) ways to evaluate skills in creativity; (3) articles and ideas on creativity and problem-solving, including predictors of problem-solving success; and (4) how to find time to teach problem-solving.

Describes a companion experiment to the experimental study of the di-iodide visible absorption spectrum. Experimental details, interpretation, and data analysis are provided for an analysis of the di-iodide fluorescence excited by a visible laser, using a Raman instrument. (CS)

Describes a student project in analytical chemistry using sheet silicates. Provides specific information regarding the use of phlogopite in an experiment to analyze samples for silicon, aluminum, magnesium, iron, potassium, and fluoride. (CS)

Discusses several aspects of software evaluation, suggesting that software should fit into an existing course and that students and faculty colleagues should be involved in the evaluation process. Also provides sources of evaluation guides, actual educational software evaluations, and software awareness materials. (JN)
