Y5/6 (A): Materials: Properties and changes
Exploring the properties of everyday materials and reversible and irreversible changes to them.
We’re monitoring the upcoming 2025 National Curriculum updates and will revise our resources when we know more. Learn more
Unit outcomes
Pupils who are secure will be able to:
- Determine the hardness of different materials and link this to their uses.
- Determine the transparency of different materials and link this to their uses.
- Determine the thermal and electrical conductivity of different materials and link this to their uses.
- Demonstrate, identify and describe reversible and irreversible changes.
When working scientifically pupils who are secure will be able to:
- Evaluate the hardness test to determine the degree of trust in the results.
- Plan and draw a table of results.
- Write a detailed, organised and easy to follow method.
- Write a prediction using prior knowledge of the states of matter.
- Analyse observations about rusting and use them to support a conclusion.
- Measure accurately in centimetres.
