Discusses the period of transition and self examination of the museology of science. Defines the main issues and limits of the museum as a means of transmitting a scientific culture and scientific ways. (Author/RT)

Hampshire College needed to create opportunities for advanced undergraduates to have extensive laboratory or field experience in experimental sciences. A general biochemistry course, taught almost entirely in the laboratory, is described. The focus of the course is enzymes as catalysts and as proteins. (MLW)

Chromium(VI) compounds are classified as oxidizers and must be specially packaged and transported for disposal while Cr(III) compounds are considered nonoxidizers. A process which reduces Cr(VI) to Cr(III) by adding sodium metabisulfite followed by neutralization with magnesium hydroxide is explored. (MVL)
