Science KS 3 Unit 7G Particle model of solids, liquids and gases

In this unit pupils:

• learn how the particle model can be used to explain differences between solids, liquids and gases.
• explore how experimental evidence relates to theories and models.

In scientific enquiry pupils:

• use the particle model to explore the interplay between scientific theories and evidence.
• evaluate whether evidence supports or refutes explanations of phenomena.

This unit is expected to take approximately 7.5 hours.
