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
- Distinguish 'dissolve' from 'melt' correctly in context and explain the difference
- Use 'soluble' and 'insoluble' accurately when describing whether a material dissolves in water
- Explain the difference between evaporation and condensation using the correct terms
