The number of flies that crawl through a small hole from one chamber to another is used to demonstrate principles of chemical kinetics. (CP)

The author describes a special experiment making peanut brittle and amusing activities based on chemical nomenclature used as motivational tools. (CP)

A baby-food jar is the constant in this group of ten basic science experiments. (Editor)

The product test and an experimental approach to the guise of matter, constitutes one approach in learning about materials. (Editor)

Discusses expanding user community seeking access to synchrotron radiation sources, properties/sources of synchrotron radiation, permanent-magnet technology and its impact on synchrotron radiation research, factors limiting power, the density of synchrotron radiation, and research results illustrating benefit of higher flux and brightness. Also…

Uses an example of literature error to illustrate several principles often difficult to present to chemistry students. Indicates how the significance of previously reported experimental results is changed when previously reported assumptions are replaced by an alternative set of assumptions leading to a self-consistent interpretation of the…

Describes a group experiment demonstrating the use of conductivity measurements in the application of kinetic methods of nucleophilic aliphatic substitution. (CS)
