Describes four cases for which simulation techniques can be used to analyze the kinetics of the chemical system. Included are series first-order and enzyme kinetics. (MA)

This experiment is designed specifically for students with little knowledge of radical reactions and provides an introduction to the gas-phase chemistry of radicals. Experimental planning based on the student's own observation is an important component of the experiment. (Author/MA)

Describes the construction of an inexpensive, highly reliable, milli-degree temperature controller and differential thermometer from an extremely stable thermistor and other readily available materials. Actual construction time is relatively short for both devices. Illustrations are included. (Author/MA)

Chemical bonding, for most simple complexes, is described in the Mulliken-Walsh Molecular Orbital (MO) theory. (CP)

Describes a novel approach to the computation of probability contours with the use of a pocket calculator. (CP)

The construction of an operational amplifier for use in a chemical instrumentation course is described. (CP)

Describes four demonstrations of the Leidenfrost phenomenon; floating of liquid drops on their own vapor above a hot surface, delayed quenching of red-hot brass by water, explosion of vessels containing suspended liquid droplets, and momentary incombustibility of living tissue immersed in boiling oil. (Author/GA)

This article describes two simple undergraduate heat transfer experiments which may reinforce a student's understanding of free convection and radiation. Apparatus, experimental procedure, typical results, and discussion are included. (Author/BB)

This article describes the undergraduate ChE thermodynamics course at Drexel University and the reasons for incorporating a series of laboratory experiments into the course. Included is a list of lecture topics and a description of each of the experiments. (BB)

Reviews the phase transfer technique for conducting reactions between molecules with widely different solubility properties. (SL)

Describes demonstrations of gaseous acid-base reactions and variations on traditional "clock" reactions. (SL)

Reviews the purpose of tests and examinations and presents several examples of suggested test items which are designed to increase the teacher's knowledge of student ability. (SL)

Presents six short excerpts on energy consumption, energy use, energy cost, energy reserves, and gas from coal. (SL)

With a sample of 229 ninth-grade chemistry students, an investigation of students' retention abilities as related to instructional approach (inductive or deductive), IQ, gender, and anxiety level was conducted. Results showed that subjects experiencing deductive instruction performed slightly better on an immediate retention test. Girls…

Outlines the sources of nuclear power, types of nuclear reactors, factors involved in the processing of uranium, and problems of radioactive waste storage. (SL)
