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.
