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)

Conveys an appreciation of enzyme kinetic analysis by using a practical and intuitive approach. Discusses enzyme assays, kinetic models and rate laws, the kinetic constants (V, velocity, and Km, Michaels constant), evaluation of V and Km from experimental data, and enzyme inhibition. (CW)

Shows how the rate of reaction can be studied using a simple electronic device that overcomes the difficulty students encounter in solving the differential equations describing chemical equilibrium. The device, used in conjunction with an oscilloscope, supplies the voltages that represent the chemical variables that take part in the equilibrium.…

An applied course designed to allow students to formulate pharmacokinetic recommendations individually for actual patient data and compare their recommendations to those of a pharmacokinetic consulting service is described and evaluated, and an objective student evaluation method is outlined. (MSE)

Suggests several mechanisms for catalysis by metal ion complexes. Discusses the principal factors of importance in these catalysis reactions and suggests reactions suitable for laboratory study. (MLH)

Presents an inorganic oxidation-reduction kinetics experiment, and describes a low cost (less than $50) modification of the Bausch and Lomb Spectronic 20 Colorimeter which will provide a linear output in absorbance. (MLH)

Discusses the use of the System Dynamics technique in simulating a chemical reaction for kinetic analysis. Also discusses the use of simulation modelling in biology, ecology, and the social sciences, where experimentation may be impractical or impossible. (MLH)

This study was conducted to describe in detail Korean students' conceptual change learning processes in the study of kinetic theory of gases. The study was interpretive, using multiple data sources to achieve a triangulation of data. Three students from a public high school for boys served as representative cases. How epistemological aspect and…

Discusses roles played by inelastic molecular collisions in gas molecular theories and suggests the inclusion of inelastic aspects in the freshman chemistry course. (CC)

Speed and acceleration tasks were administered to children in grades three through six. Piaget's results were replicated. Suggestions concerning the appropriate grade level to introduce different types of motion tasks are made. (AL)
