KS3 Curriculum Overview: Science


The Science curriculum follows ten big ideas; Forces, Electromagnets, Waves, Energy, Matter, Reactions, Earth, Genes, Organisms and Ecosystems.

All topics we cover fit in to one (or two for some GSCE) of these big ideas, and knowledge is built up in these areas throughout the 5 year curriculum.
