Mechanical theories are presented in this unit of the Project Physics text for senior high students. Collisions, Newton's laws, isolated systems, and Leibniz' concept are discussed, leading to conservation of mass and momentum. Energy conservation is analyzed in terms of mechanical energy, heat energy, steam engines, Watt's engine, Joule's…

Nuffield Secondary Science is a set of tested materials from which teachers can prepare courses for students in grades 9-11 (approximately) who do not intend to major in science. The materials are designed for British secondary schools but are adaptable for other countries. The Teachers' Guide to the entire set of materials is described in SE 015…

Describes an inexpensive apparatus used to study the kinetics of fast reactions. Suggests an appropriate reaction for study, and laboratory techniques. (MLH)

This paper describes an experiment designed to reveal the consequences of the development of a concentration boundary layer. The rate of a mass transfer limited electrochemical reaction is measured and used to obtain the dependence of average Sherwood number on Reynolds number and entrance length. (Author/BB)

Explains that some nuclear scattering phenomena can be attributed to states in which two nuclei are bound to each other at their surfaces, revolving and vibrating for a time before coalescing or disintegrating. (Author/GA)

Discusses the principle of nonisothermal kinetics and some of the factors involved in such reactions, especially when considering the reliability of the kinetic parameters, compared to those of isothermal conditions. (GA)

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)

Kinetic Psychotherapy consists of young children's games which facilitate interaction and mobilize feelings. When used as a mode of family therapy, this process enables the therapist to catalize and observe change in the family's patterns of communication, interaction, and level of functioning while involving members in a relatively nonthreatening…

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)

Presents a method for simplifying calculations in quantum chemistry by calculating molecular energy from the electrostatic theorem. (SL)

Describes an experimental method of measuring the molecular weight and subunit corporation of an oligomeric protein. (SL)

Describes a laboratory kinetic experiment which demonstrates the important phenomenon of general catalysis by bases and/or acids. (SL)

Presents a model describing the vibrations of a mass connected to fixed supports by "ideal" Hooke's law springs which may serve as a starting point in the study of the properties of irons in a crystal undergoing soft mode activated transition. (SL)

Presents a completely arithmetic development of Newtonian dynamics in which all classical conservation laws are valid and all equations are in forms amenable to high-speed digital computer computation. (SL)
