The Basic Electricity Kit has been designed as a low-cost, attractive and flexible alternative to the circuit-board approach to pupil investigations into simple circuits. Each component such as a switch, rheostat, bulb holder, etc. is mounted on its own individual plastic panel with 4mm sockets. The panels are then formed into circuits by connecting them together using 4mm stackable leads. This equipment is suited not just for teaching basic concepts about circuits, for key stage 2 students, but also has applications for further study into key stage 3 areas. Each kit is supplied in two polystyrene trays which keep the units organised.
