There are ten big ideas at key stage 3. The topics are sequenced to develop an understanding of a big idea by multiple interactions. Topics in each big idea are ordered from simpler, topics to more abstract ones. The curriculum develops pupil’s knowledge, from understanding to application. Working scientifically runs along side all topics developing essential scientific skills. The curriculum map below provides an overview of the topics covered throughout years 7, 8 and 9.
