Heating & Cooling Changes
Observe and describe that some materials change state when heated or cooled, and measure the temperature at which changes occur in degrees Celsius
Typical age: 7–9 years

Needs first
- States of Matter VocabularyREQUIRED
Describing and measuring changes of state requires solid/liquid/gas vocabulary and the term 'change of state'
- Drawing Particle DiagramsREQUIRED
Observing and describing change of state requires reading particle diagrams showing how arrangement changes on heating or cooling

- How Materials Change StateREQUIRED
KS3 heating/cooling curves and particle-level explanation extends KS2 observation that materials change state at specific temperatures
- The Water Cycle
Water cycle benefits from curriculum states of matter (heating/cooling changes state)
- Where water is found on Earth
Understanding state changes supports knowing water as solid (ice) and liquid
- Evaporation & the Water CycleREQUIRED
Must understand state changes before learning about evaporation/condensation in water cycle
- Reversible ChangesREQUIRED
Must understand state changes before categorising them as reversible
- Matter Is Made of ParticlesREQUIRED
Must observe state changes before explaining them with particle model
- Solids, Liquids & GasesREQUIRED
Must classify states of matter before understanding changes between states
