When CLEAPSS, the organisation now well known as a source of advice on health and safety in school science, came into being, it was called the Consortium of Local Education Authorities for the Provision of Science Equipment (CLEAPSE). This short article describes the role of the Science Masters' Association in its creation and the…

This article describes the design, delivery, evaluation and impact of a CPD course for physics and chemistry teachers. A key aim of the course was to use the context of the James Webb Space Telescope project to inspire teachers and lead to enriched teaching of STEM subjects. (Contains 1 box and 3 figures.)

Natural arsenic salts are present in all waters, with natural concentrations of less than 10 parts per billion (ppb). Unfortunately, there is an increasing number of countries where toxic arsenic compounds in groundwater, which is used for drinking and irrigation, have been detected at concentrations above the World Health Organization's…

Describes the construction of an apparatus that can be used as a quick and easy model of the passage of a longitudinal wave in a steel or aluminum rod. Employs expandable steel springs. (DDR)

Describes a series of simple but spectacular chemistry demonstrations designed to capture children's imaginations. The demonstrations take the minimum amount of time to prepare, are relatively safe to dispose of, and reliable. (Author/WRM)

Describes how practical science can be taught using locally-collected junk materials and encourages a new approach to science teaching in rural India. Emphasizes science relevant to the villages to which children will return to when they leave school. (DDR)

Describes a method to examine preparations of rocks in thin sections between crossed polaroids using a converted biological microscope or a homemade polariscope. (JRH)

Describes a variety of experiments and activities such as refractive index by an interference method, Young's third slit, a microscope problem, uses of a hand stroboscope, an acceleration game, an aluminum thermometer, why milk boils over, and others. (BR)

Describes a set of experiments for the catalytic oxidation of alkenes to aldehydes and ketones which can be carried out in a test tube by the student. (BR)

Describes the inexpensive construction of an uptake volume potometer uptake and loss potometer, and experiments on plants that can be conducted with the equipment. (BR)

Describes the construction of a model suitable for demonstrating the principles of refrigeration in secondary science classes. (JR)

Describes how some experiments in physics can be presented in class using cheap materials. How to produce an electrostatic charge using a polythene bottle and how to make a tissue paper electroscope using a tin can are among the experiments described. (HM)
