Describes an undergraduate biological chemistry laboratory experiment which provides students with an example of pseudo-first-order kinetics with the cardiac glycoside inhibition of mammalism sodium and potassium transport. (SL)

Discusses theory of thermodynamics of the equilibrium in solution and dissociation-dimerization kinetics. Describes experimental procedure including determination of molar absorptivity and equilibrium constant, reaction enthalpy, and kinetics of the dissociation-dimerization reaction. (JM)

Discusses student use of the computer with mathematical models and with laboratory simulations. Examples given. (DS)

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)

Describes an apparatus which allows one to study the speed distribution, the gravitational distribution, and the mean free path of steel balls agitated into two-dimensional motion through collisions with the moving walls of their enclosure. (Author/GA)

Analyzes projectile motion using symmetry and simple geometry. Deduces the direction of velocity at any point, range, time of flight, maximum height, safety parabola, and maximum range for a projectile launched upon a plane inclined at any angle with respect to the horizontal. (Author/GA)

Describes classroom activities that involve student movement to demonstrate principles of kinetics. This classroom method can be used for any topic related to dynamic processes. The method used in this activity illustrates Brxnsted-Lowry acid-base theory and redox reactions. Takes advantage of analogies between proton and electron transfers. Use…

Presents a qualitative activity whereby students observe the effects of temperature on commercial lightsticks. Includes Internet resources. (WRM)

Describes a general chemistry level kinetics experiment requiring three 3-hour laboratory periods. Data analyses can be accomplished with graphical techniques or a non-linear least squares computer program. (MLH)

Describes a computer simulation experiment in which physical chemistry students can determine all of the kinetic parameters of a reaction, such as order of the reaction with respect to each reagent, forward and reverse rate constants for the overall reaction, and forward and reverse activation energies. (MLH)

Suggests using a bicycle road rally in the teaching of kinematics and presents a list of suggestions for running the rally. Suggests a ski trip and instruction in the physics of skiing to create student awareness of physics relevance. (GS)
