Presents a unit on chemical reaction kinetics that consists of a predemonstration activity, the demonstration, and a set of postdemonstration activities that help students transfer the concepts to actual chemical reactions. Simulates various aspects of chemical reaction kinetics. (JRH)

Describes an undergraduate physical chemistry experiment in which the acid catalyzed hydrolysis of sucrose is used to determine the catalytic coefficient of the hydronium ion, the catalyst in this reaction. (MLH)

Describes two experiments, one involving the electrolysis of potassium iodide and the other involving a diffusion process in solid copper. (GS)

Describes an open-ended experiment involving a bioinorganic system that provides the student a direct link between thermodynamics and kinetics. It utilizes a rapid reaction technique and requires one to clearly understand the relationship of experimental observable (absorbance) to a mechanism. (GS)

Derives the precessional period of a Foucault pendulum without using small oscillation amplitudes. Shows that if the path of the pendulum passes through the origin, the periods for differing amplitudes are essentially the same. (GA)

Describes the energy education program given for elementary school groups at the Museum of Science in Boston. Several energy machines or demonstrations are described and their use in this energy education program is outlined. Also some other suggestions to illustrate the use, storage, and transformation of energy are presented. (MDR)

Describes an experiment that generates data for calculating the ratio of molecular separation in a gas to molecular diameter. (GS)

Describes an investigation involving acid hydrolysis and using both volumetric and kinetic techniques. Presents examples of the determination of the rate constant and its variation with temperature. (GS)

Describes a model in which a steel ball bounces in synchronism with a vertically oscillating piston. The period of oscillation can be varied over a 3:1 range with the amplitude kept constant. As the period is increased, the ball bounces higher, contrary to the intuition of most observers. (Author/GS)
