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.
