The High School Project on Astrophysics Research with Cosmics (HiSPARC) is an international project in which secondary schools and academic institutions join forces to form a network of detectors to measure cosmic rays with extremely high energy. We present results of research done by students at the King Edward VI High School For Girls,…

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 contribution of…

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…

Short articles describe the use of a lever to transfer energy between pucks on a frictionless surface, a demonstration of the principle of conservation of linear momentum, the construction of an inexpensive joulemeter, the design and construction of a simple logic demonstration board using integrated circuits, mounting of Geiger-counters to…

Short articles present ideas for demonstration equipment useful for the junior high school science: three-dimensional magnetic fields, model clocks, and smoke-ring puffers." (AL)

Describes the development of a modified spherometer in which the position of the central leg is measured electrically. (MKR)

Short articles describe techniques for demonstrating corrosion of metallic couples, colloidal dispersion of light, the biodegradability of detergents, the laboratory preparation of chlorine in model electrolytic cells, and the detection of food colorings in candy. (AL)

Short articles describe techniques suitable for junior high school science, including the use of a toy drinking bird" to start discussion, using cobalt chloride solution to demonstrate convection currents, demonstration of the relationship between freezing point and concentration, and instructions for building a simple lens camera, a circuit…

Short articles describe the production, photography, and analysis of diffraction patterns using a small laser, a technique for measuring electrical resistance without a standard resistor, a demonstration of a thermocouple effect in a galvanometer with a built-in light source, and a common error in deriving the expression for centripetal force. (AL)

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