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
Suggested ages 7–9
Learning journey
Your child is investigating how materials behave — classifying substances by their properties, understanding why different materials are used for specific purposes, and exploring how heating and cooling can change materials.
Evidence of understanding
- Describe melting (solid to liquid) and freezing (liquid to solid) with everyday examples
- State that water freezes at 0°C and boils at 100°C
- Explain that heating adds energy causing particles to move more, leading to state changes
Assessment prompt
Can Heating & Cooling Changes explain what happens to an ice cube when you heat it, and at what temperature water freezes and boils?
