Discusses distillation of liquid mixtures with the emphasis on experimental work. A number of experiments, intended for chemistry secondary school teachers in the United Kingdom, are included. (HM)

The internet offers considerable potential for open and distance learning in psychology. Research reveals an abundance of psychology demonstrations and experiments available online, directed both at students and potential research participants. Although expertise is being developed to overcome the technical problems associated with this medium,…

The Plaut, McClelland, Seidenberg and Patterson (1996) connectionist model of reading was evaluated at two points early in its training against reading data collected from British children on two occasions during their first year of literacy instruction. First, the network's non-word reading was poor relative to word reading when compared with the…

Presents recommendations sent to schools by the Laboratory Safeguards Sub-Committee in the United Kingdom to prevent hazards of a number of chemicals. How to avoid phosphorous fires and accidents from doing dangerous experiments in chemistry are also included. (HM)

Describes the use of transistors instead of valves for Lecher line and radiation demonstrations. Two oscillator circuits which provide power for Lecher line use are described. Impedance of Lecher line is also discussed. (HM)

Describes a simple experimental system whereby the comparative actions of long, medium, and short-acting barbiturates can be demonstrated in a relatively short period of time under optical microscopy using pollen grains as the biological test or assay system. (Author/HM)

Discusses some basic physical ideas about light scattering and describes a simple Raman spectrometer, a single prism monochromator and a multiplier detector. This discussion is intended for British undergraduate physics students. (HM)

Suggests sterile procedures which can be carried out to take a sample of blood (of one or two drops) from pupils to be used in school biology courses in the United Kingdom. (HM)

Describes how social aspects of science can be incorporated into teaching soap and detergents in British secondary chemistry and general science courses. Historical background to the use and production of soap and the development of detergents are also presented. (HM)

Discusses the mechanics of how an actual oil reservoir works and provides some technical background in physics. An experiment which simulates an oil reservoir and demonstrates quantitatively all the basic concepts of oil reservoir rock properties is also presented. (HM)

Presents nine selected physics notes which could be used in selected physics courses. Each includes the name of the author and a description of activities suggested. (HM)

This article focuses on the changes made in the undergraduate laboratory program of the first degree course in chemical engineering at the University of Bath (England). Describes experiments relating to the Engineering Applications 1 (EA1) requirements set by the Engineering Council. (YP)

Explores pupils' (n=800) ideas about what scientists do, their more general knowledge about theories and how they change, and their impressions of how theory and experiment interact in the school science that they have experienced. Discusses teacher and out-of-school effects, gender, school work, and development with age. Contains 22 references.…

Bacterial antibiotic resistance remains a problem of clinical importance. Current microbiological methods for determining antibiotic resistance are based on culturing bacteria, and may require up to 48 hours to complete. Molecular methods are increasingly being developed to speed the identification of antibiotic resistance and to determine its…

Presents two articles which are part of a series concerned with safety in school science in the United Kingdom. The two articles deal with restricted chemicals and experiments. (HM)
