Describes four science experiments relating to energy developed for interdisciplinary general science courses. (SL)

Describes two experiments for a sophomore level organic chemistry utilizing commercially available borane-methyl sulfide (BMS). (SL)

Described is a school project to investigate aggregations in flatworms which may be influenced by light intensity, temperature, and some form of chemical stimulus released by already aggregating flatworms. Such investigations could be adopted to suit many educational levels of science laboratory activities. (DS)

Describes an experiment for the determination of water/lipid distribution ratios of drugs. (SL)

HEARTS (Higher Education, the Arts and Schools) project was established with the intention of strengthening the arts element of initial training of primary school teachers. During the academic years 2004/6, six higher education institutes (HEIs) were given financial and practical support to introduce new programmes of arts work into their…

Presents the results of an experiment designed to test two hypotheses: (1) a delay of two weeks at room temperature will have no effect on the viability of fertile chicken eggs and (2) refrigeration will have no effect on the viability of fertile chicken eggs. Experimenters were the author and two ninth-grade students. (PEB)

Provides methodology for carrying out the synthesis of sec-butyltoluene by the Friedel-Crafts alkylation of toluene. Suggests using simple elemental aluminum as the catalyst in place of AlCl3 or amalgamated aluminum. Notes satisfactory results for both macro- and microscale operations. (MVL)

Examines the influence of enzyme and substrate concentrations, pH, temperature, and inhibitors on catalytic activity. Follows the influence of different phosphate concentrations in the growth medium on enzyme activity. Studies regulation of enzyme synthesis by repression. Includes methodology for six experiments.
