Proposes a model for kinetic processes said to be similar in computational effort and yielding similar results to conventional transition state theory (TST), while maintaining parsimony and credulity. Argues that partitioning of states into groups be limited to energy space in contrast to TST. (JM)

Discussed is the idea that models should be taught by emphasizing limitations rather than focusing on their generality. Two examples of gas behavior models are included--the kinetic and static models. (KR)

Describes a method, considered appropriate for presentation to undergraduate students in materials science and related courses, for the calculation of cohesive energies of the alkali metals. Uses a description based on the free electron model and gives results to within 0.1 eV of the experimental values. (Author/GS)

The Briggs-Haldane assumption is used as the basis for the development of a kinetic model for enzyme catalysis. An alternative definition of the steady state and examples of realistic mechanisms are provided. (KR)

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)

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)

Described is a method of utilizing the standard ball and stick models, used in demonstrating molecular structure, for building two electron bonding components. Included is the construction of several molecules with word and picture descriptions. (Author/DS)

This book helps children develop the capability and confidence to design, construct, and evaluate working models. Projects in this book are suitable for students in grades K-4, but may be adapted for older students. Step-by-step explanations for each project are meant as guidelines and completion of the project is not limited to a single correct…
