Describes a simple high-performance liquid chromatography experiment for undergraduate biochemistry laboratories. The experiment illustrates the separation of polypeptides by a step gradient elution using a single pump instrument with no gradient attachments. Discusses instrumentation, analysis, a sample preparation, and results. (CW)

Describes an experiment in which students are given a naturally occurring oligosaccharide as an unknown and are asked to determine both its monosaccharide composition and its structure. Discusses methods and experimental techniques including thin layer chromatography and the use of enzymes. (CW)

Described is a simple device, that uses a laser beam to simulate P waves. It allows students to follow ray paths, reflections and refractions within the earth. Included is a set of exercises that lead students through the steps by which the presence of the outer and inner cores can be recognized. (Author/CW)

Discusses ways that chemists have traditionally used models to represent chemical structures. Suggests new ways to construct three-dimensional models of receptor sites using thermoplastics or heavy aluminum foil. Provides sketches and photographs of several models. Points out the advantages of using such models over traditional two-dimensional…

Discusses the need for student research-type chemistry projects based upon "unknown" metal complexes. Describes an experiment involving the product from the reaction between cobalt(II) chloride, ethane-1,2-diamine (en) and concentrated hydrochloric acid. Outlines the preparation of the cobalt complex, along with procedure, results and…

Studies the interviews of 24 professional scientists to seek their views on the long range effects of their initial training. Analyzes the interviews for content, teaching, and types of learning experience. Concludes with a discussion of the implications of the findings for science education. Argues for a reduction in content. (CW)

Reports on the results of a University of Arizona experiment that used electronic mail to supplement traditional modes of student/instructor interaction in four courses in electrical and computer engineering. Results indicated that students liked electronic mail to supplement their discourse with their instructors. (TW)

Describes the interdisciplinary activities of the extension unit known as the Office of Environmental Programs at the University of Nebraska-Lincoln. Focuses on the coordination and training involved in programs dealing with pest management and water quality. (TW)
