KS3 Science resources
Equip your students with the knowledge to excel in their own scientific investigations.
Aligned with the National Curriculum, our units are thoughtfully organised into separate courses, covering Biology, Chemistry and Physics. We begin with foundational units on cells, particles, and forces, and then progressively delve into intermediate and advanced units on interdependence, chemical reactions, circuits, the Periodic Table, forces and pressure, and photosynthesis and respiration.
Ignite a love for science with Access KS3 Science resources.
