Year 3 children investigate the invisible force of magnetism: north and south poles, attract and repel, and which materials are magnetic — including the tricky truth that not all metals stick! It is a ready-to-teach PowerPoint scaffold for an hour-long lesson on forces and magnets, matched to the KS2 science curriculum. Includes a predict-and-test magnet lab, a magnet fishing challenge, a floating paperclip worked example and a partner quiz.
