Subject Overview 

Key stage 3 

The Government say that ‘The principal focus of science teaching in key stage 3 is to develop a deeper understanding of a range of scientific ideas in the subject disciplines of biology, chemistry and physics’ and that ‘Pupils should begin to see the connections between these subject areas and become aware of some of the big ideas underpinning scientific knowledge and understanding’. 

To encourage students to relate scientific explanations to phenomena in the world around them we have carefully created our own contextually based KS3 curriculum by adapting Pearson ‘Exploring Science’ resources. We use modelling and abstract ideas to further develop and evaluate explanations to teach the sciences in a way that ensures students have the knowledge to enable them to develop curiosity about the natural world, insight into working scientifically, and appreciation of the relevance of science to their everyday lives.  

Students will study the three sciences separately for a total of 12 hours every two weeks over the two year course:
