At the end of this unit
in terms of scientific enquiry
most pupils will: describe and explain observations, using the particle model
some pupils will not have made so much progress and will: describe observations and try to offer explanations for them
some pupils will have progressed further and will: compare explanations of a phenomenon and evaluate whether evidence supports or refutes them
in terms of materials and their properties
most pupils will: classify materials as solid, liquid or gas; explain their classification of some 'difficult' materials; describe materials as being made of particles and describe the movement and arrangement of these, and begin to use the particle model to explain phenomena,
eg the mixing of liquids, the expansion of a metal bar
some pupils will not have made so much progress and will: classify materials as solid, liquid or gas and recognise that materials are made of particles
some pupils will have progressed further and will: use the particle model to explain a range of phenomena
