Peer reviewedRussell, Arlene A.; Mitchell, Bernie L. – Journal of Chemical Education, 1979
Describes the use of cassette tape recordings in preparing freshman chemistry students for experiments in laboratories. The tapes are said to have decreased student anxiety in the laboratory and increased laboratory skills. (SA)
Descriptors: Chemistry, College Science, Higher Education, Laboratory Procedures
Peer reviewedWilliams, Kathryn R.; And Others – Journal of Chemical Education, 1990
Discussed are the procedures and results involved in this activity. Student results in undergraduate laboratories indicate high quality results and relative ease of the analysis. (CW)

Peer reviewedHyman, M.; Rowe, M. W. – Journal of Geological Education, 1979
An inexpensive apparatus for demonstrating low temperature mineral synthesis in an undergraduate geology laboratory is described. (Author/SA)

Peer reviewedRoberts, A. V.; Short, K. C. – Journal of Biological Education, 1979
Recommendations are given for obtaining high quality preparations of chromosomes with relatively little equipment using an improved Feulgen-squash technique. (Authors/SA)

Peer reviewedPerley, James E.; Glass, A. D. M. – Journal of Biological Education, 1979
Presents a method for microscopically examining cytoplasmic streaming in root cells, and physiologically examining the delivery of ions to the xylem exudate. The expected result does not occur and the authors believe that students learn to re-examine the assumptions, thereby increasing their skills in scientific inquiry. (Authors/SA)
