Kautz, Allan D. – American Journal of Physics, 1980
Describes an experimental setup which allows the student to investigate the resonance characteristics of a vibrating plate using a small, circular steel plate clamped around its perpiphery. (HM)
Descriptors: College Science, College Students, Electricity, Higher Education

Keltner, Paul – Journal of Chemical Education, 1994
Argues that with the increase in hands-on approaches to science, teachers are using more hazardous science demonstrations with less conceptual understanding than they should have. Poses questions for discussion within the chemical education community regarding the presentation of demonstration-based sessions at conferences. Stresses the…

Kolb, Doris, Ed. – Journal of Chemical Education, 1989
Presents two demonstrations using the overhead projector: (1) describes how to build a projecting voltmeter and presents uses for the classroom; and (2) investigates the color of fluorescent solutions by studying the absorption and transmission of light through the solutions. (MVL)
Descriptors: Chemistry, College Science, Electricity, Higher Education

Cochran, Philip A. – American Biology Teacher, 1989
Describes modifications and procedures needed for parasitic lampreys to be kept in a closed system. Presents information dealing with obtaining the organisms, tank modifications, temperature, feeding, disease prevention, and animal welfare. A discussion is included. (RT)
Descriptors: Animals, Biology, College Science, Culturing Techniques

Gerlovich, Jack A.; Miller, Jim – Journal of Chemical Education, 1989
