The 24 contributions to this volume were written by coaches, sport scientists, and medical authorities who surveyed recent research on biomechanics, physiology, psychology, nutrition, treatment of injuries, and training techniques for cyclists. There are four sections: (1) biomechanics and physiology; (2) research: techniques and results; (3)…

Procedures for demonstrating thermodynamic changes, kinetics and reaction mechanisms, equilibrium, and LeChatelier's principle are presented. The only materials needed for these demonstrations are beakers, water, assorted wooden blocks of varying thickness, assorted rubber tubing, and a sponge. The concepts illustrated in each demonstration are…

Several interesting and important examples of kinetic stability and kinetic control in organic systems are discussed. Audiovisual aids, lecture demonstrations, and laboratory activities that can be used to convey the material in a clear and stimulating fashion are also described. (JN)

Proposes an approach to chemical kinetics and mechanism using statistical games, illustrating its use in monomolecular, catalytic, autocatalytic, consecutive, and equilibrium reactions. Major features of the games are also outlined and discussed. (JN)

Describes a set of experiments (for senior-level biochemistry students) which permit evaluation and estimation of rate and equilibrium constants involving an intermediate in the alpha-chymotrypsin mediated hydrolysis of ortho-hydroxy-alpha-toluenesulfonic acid (I). The only equipment required for the experiments is a well-thermostated double beam…

Students' cars and wristwatches are used as "apparatus" to introduce and demonstrate Newton's second law of motion. Forces acting on cars are discussed and typical student data (for different makes of cars) are provided. Data could also be used in discussions of work, horsepower, efficiency, and energy cost. (JN)

Provides an explanation for the observed motion of frisbees, can lids, "clay pidgeons," and flat stones when these objects are thrown through the air. Explanation focuses on forces (gravity and air), torque, and gyroscopic precession. (JN)

Discusses contributions of computers to research in magnetic and inertial-confinement fusion, charged-particle-beam propogation, and space sciences. Considers use in design/control of laboratory and spacecraft experiments and in data acquisition; and reviews major plasma computational methods and some of the important physics problems they…

Various aspects of chemical equilibrium were discussed in six papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982). These include student problems in understanding hydrolysis, helping students discover/uncover topics, equilibrium demonstrations, instructional strategies, and flaws to kinetic…

Describes modification of a chemical reaction to a single 4 1/2-hour laboratory period. Reaction kinetics between 2, 4-initrochlorobenzene and piperidine to form 2, 4-dinitrophenyl-piperidine and piperidinium hydrochloride are followed conductometrically at three temperatures to obtain data to calculate activation parameters. (Author/JN)

Three experiments using merocyanine M suitable as an integrated laboratory experience for undergraduates are described. Experiments demonstrate: complete molecular cycle composed of photochemical, thermal, and protolytic reaction steps; kinetics of cis-trans isomerization of the dye; and mechanism of base catalysis for thermal isomerization of the…

Newton's laws can be illustrated by having physics students participate in various activities while on roller skates. Several examples of such activities (including photographs) are provided. (JN)

Several good features of a projectile motion experiment (students fire their own rockets) are described, including accuracy achieved, low cost and relative safety. Also described is a simple novelty toy (originally distributed by McDonalds foods) illustrating physics concepts. Blowing on this toy pipe propels a thread around in a loop. (JN)

Described is an advanced undergraduate kinetics experiment using buffer dilutions to determine spontaneous rate, catalyzed rate, and reaction order. The reaction utilized is hydrolysis of p-nitro-phenyl acetate in presence of imidazole, which has been shown to enhance rate of the reaction. (Author/JN)

Background information and experimental procedures are provided for three lecture-demonstrations (involving hydrolysis of tetra-butyl chloride) illustrating: (1) common-ion or mass law effect; (2) effect of changing ionizing power of a solvent on a solvolysis reaction; and (3) collecting/plotting data to illustrate a first-order reaction.…
