Sciences
BackScience has three main disciplines: Biology, Chemistry and Physics. Studying Science helps us understand the natural and physical world around us through experimentation and observation.
Key Stage 3 Science Learning Journey


Year 7
The intent of the Year 7 curriculum is to build a foundational understanding of core scientific frameworks across biology, chemistry and physics.

Year 8
The intent of the Year 8 curriculum is to build a foundational understanding of core scientific frameworks across biology, chemistry and physics. This curriculum develops students' conceptual literacy, practical investigative skills, and critical thinking. It transitions learners smoothly from KS2 primary science to KS3 secondary science. To deepen conceptual frameworks in biology, chemistry, and physics by linking microscopic interactions to macro-scale observations. This curriculum builds upon Year 7 foundational concepts to model energy conservation, human physiology, chemical trends, and planetary systems. It emphasises experimental variables, chemical equations, mathematical manipulation of physical models, and data-driven ecological awareness.
