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…

Describes an experiment that provides a study of the different colors and shapes of crystals of transition metal dimethylglyoxime complexes with the use of a low power microscope. Discusses the preparation and examination of the crystals. (CW)

The use of the earthworm as a laboratory animal for studying the effect of starvation on nitrogen metabolism is discussed. Simple techniques and methods are presented allowing in vivo physiological responses to be compared with changes in the enzyme potential of gut tissue. (Author/MA)

Describes an experiment demonstrating the frustration of totally reflected visible light. (SL)

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. (MVL)

Offers several advantages over other possibilities as the enzyme of choice for a student's first exposure to a purification scheme. Uses equipment and materials normally found in biochemistry laboratories. Incorporates several important biochemical techniques including spectrophotometry, chromatography, centrifugation, and electrophoresis. (MVL)

Describes an experiment which measures the surface tension of a liquid and illustrates interfacial spreading and the Marangoni effect. (MLH)
