Contents enable a class of up to 30 students working in groups to carry out investigations into electrical components and circuits using structured work cards and robust components. The components are mounted on to tough yellow plastic tiles each fitted with two 4mm terminals. The components can be made into circuits by connecting them together using the supplied 4mm leads. Each component tile features the correct circuit symbol for the specific component. The supplied work cards have been written by our in-house experts and reflect the current KS3 national curriculum. The kit is supplied in Gratnells trays with lids allowing for easy packing and storage.Kit Contents:60 x 4mm Stackable Plug Lead 250mm - Red (12 x Packs of 5)60 x 4mm Stackable Plug Lead 250mm - Black (12 x Packs of 5)40 x BEK Ammeter30 x BEK Voltmeter30 x BEK Lamp Holder50 x MES Bulbs 6V 0.04A for BEK Lamp Holder (2 x Packs of 25) 10 x BEK 22 Ohm Resistor20 x BEK Push Switch10 x BEK Mounted Motor 30 x BEK Cell Holder 1 x Pack of Unilab KS3 BEK Work Cards2 x Extra Deep Storage Trays with Lids
