Presents six middle school science notes for British science teachers. Some of these notes are: (1) fingerprints; (2) the floating magnet; and (3) the production of electricity using a lemon. (HM)

Presents demonstrations, using microprocessors, to show the slow change in relative phase of two sine waves feeding the inputs of an oscilloscope and Fourier synthesis. (SK)

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)

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)

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)

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)
