Discusses two different uses of information theory in chemistry to present entropy and chemical structure analysis. (GA)

Urges the use of the immediate environment of the school to serve as a focus and a medium to help plan activities and experiments in the different subject areas of science, and in the area of environment. (GA)

Describes the construction and use of a simple apparatus to measure the magnetization density and magnetic susceptibility of ferromagnetic, paramagnetic, and the diamagnetic solids and liquids. (Author/GA)

Principles, experimental procedures, results, and discussion of this method are included here. The method was used in undergraduate laboratory courses in Toulouse, France. (BB)

Describes an experiment illustrating the absorption in the ultraviolet region to provide a simple spectrometric analytical method. (SL)

Describes a thought experiment using a general analysis approach with Lorentz transformations to show that the apparent self-contradictions of special relativity concerning the length-paradox are really non-existant. (GA)

Presents an experiment for a physical chemistry course designed expecially for students majoring in the life sciences. (SL)

Describes an experimental procedure for the analysis of common cations in solution for an introductory analytical chemistry course. (SL)

Reports an experimental procedure for introductory chemistry courses to demonstrate a homogeneously catalyzed reaction. (SL)

Describes an undergraduate biochemical experiment involving the isolation and characterization of acid phosphatase from readily available materials. (Author/SL)

Presents classroom and laboratory teaching and demonstration ideas, including a demonstration of optical rotation, automatic potentiometric titration, preparation of radioactive lead, and an organic lab practical in library resources. (SL)

Actin and myosin have now been demonstrated to be important constituents of many eukaryotic cells. Their role is primarily that of a contractile system underlying all aspects of cellular motility. Described here is a simple experimental system to demonstrate quantitatively aspects of motility and its regulation in a slime mold. (Author/MA)

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)

Describes an experiment wherein simple gamma-ray detection and analysis techniques were utilized to study radioactivity in local precipitation. (Author/SL)

An experiment on the heat conductivity of different materials are described. Applications for energy education in the elementary classroom are implied. (MDR)
