Discusses the teaching of the concept of electronically equivalent groups by comparing transition metal and nonmetal groups that have the same electronic requirements. (MLH)

Presents a sample of the outline topics and performance objectives that might be used to present acid-base concepts in an organic chemistry course. (MLH)

Discusses using the historical account of the concept of the tetrahedral carbon atom as a study in scientific methodology. (MLH)

Presents five experiments in which the unknowns for analysis are prepared by the students themselves, the analysis forming an essential part of the investigation. (MLH)

Describes an undergraduate analytical chemistry course that utilizes instrument modules, which show how the key parts of an instrument fit together and contribute to the overall operation of the instrument. (MLH)

Describes thin-layer chromatography experiments in which the students separate natural products, such as paprika, chile powder, and peppers. (MLH)

Suggests that physical chemistry courses should emphasize experimental aspects and practical applications. (MLH)

Suggests that some way be found to provide teaching jobs for chemistry Ph.D's whose main interest is chemical education. (MLH)

Describes a project-oriented high school chemistry course that utilizes laboratory units in which the students make a practical product, such as soap, thus exposing them to career possibilities. (MLH)

Discusses changes in freezing points and boiling points of solutions using simple concepts of thermodynamics to illustrate colligative properties. (MLH)

Presents a set of integrated experiments for the undergraduate inorganic chemistry laboratory, designed with the belief that a related set of syntheses, reactions, and characterization techniques sums to a greater learning experience than an equal number of unrelated experiments. (MLH)

Describes an undergraduate chemistry experiment in which an atomic absorption spectrophotometer is used for recording flame emission spectra of the diatomic carbon molecule. (MLH)
