KS3 Physics: Electricity & Magnetism — Challenge

KS3 Physics: Electricity & Magnetism — Challenge is a greater-depth stretch activity book for Key Stage 3 electricity and electromagnetism, mapped to the DfE National Curriculum. Five demanding challenges push confident learners through reasoning about resistance and calculating with voltage, current and resistance, harder series and parallel circuits including shared voltage and added branch currents, charge and materials explained by free electrons and electron transfer, and magnetic fields, magnetic materials, electromagnet uses, the compass and Earth’s field. Challenges 1–4 hold around twenty-three auto-marked questions; Challenge 5 is an open reasoning and proof task — explaining fairy lights, designing an electromagnet and reasoning about a current near a compass — with a full worked answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
