Curriculum topics

The Particle model worksheets cover the following topics:

  • states of matter
  • arrangement of particles in solids, liquids and gases
  • names of state changes
  • relative energy of particles in solids, liquids and gases
  • changes in the kinetic energy when substances change state
  • melting point and boiling point
  • using melting point and boiling point data to deduce the state of a substance at a given temperature.

If learners successfully answer questions on these topics, they can attempt the extension question. This requires learners to use melting and boiling point data to complete a table identifying the state of a substance at different temperatures.

Independent learning and metacognition

The ‘What do I understand?’ page is common to all worksheets. Learners are encouraged to develop independent learning skills and can use their reflection as a guide for revision. The feedback will also help you to identify areas where a whole class needs attention.

Answers

The teacher guidance provides model answers for each worksheet, plus guidance on learners’ common misconceptions. Learners can use the model answers to self- or peer assess.
