Why some individuals survive, reproduce and pass on their traits.
Describing Forces
Forces and Motion Basics → Describing Forces
Pushes, pulls, arrows and what a resultant force actually does.
Energy Stores and Transfers
Energy Transfers → Energy Stores and Transfers
Where energy is stored, how it moves, and why it is never lost.
Properties of Waves

Amplitude, wavelength, frequency and the wave equation.
Current, Voltage and Resistance
Electricity and Magnetism → Circuits and Current
Building circuits and using V = I x R with confidence.
Newton's Three Laws

Inertia, F = m x a, and why forces always come in pairs.
Rocks, Minerals and the Rock Cycle
Earth's Systems → Rocks, Minerals and Soil
Investigate how minerals build rocks, how the three rock families form, and how Earth materials are recycled over millions of years.
Weather Systems and Climate Patterns
Weather and Climate → Weather Systems
Track how uneven heating, air masses and ocean water drive the weather of the Gulf region and the wider planet.
Plate Tectonics and Earth's Resources
Plate Tectonics and Earth's Resources → Plate Tectonics
Use rock, fossil and seafloor evidence to explain plate motion, and connect plate history to where resources such as oil, gas and groundwater are found.
Natural Hazards, Risk and Resilience
Natural Hazards → Hazard and Risk
Analyse hazard data to judge risk, and evaluate engineering and planning solutions that make communities more resilient.
Stars, Galaxies and the Expanding Universe
The Universe → Stars and Galaxies
Follow the evidence — spectra, redshift and cosmic background radiation — that reveals how stars shine and how the universe grew.
Ionic Bonding
Ions and Our Health → Ionic Compounds and Health
How oppositely charged ions attract to build giant ionic lattices.
Particles and States of Matter
