- If pupils are unsure how to start
- Suggest they focus on the basic characteristics first (e.g., “Are the particles close together or far apart?”).
- Encourage small experiments: try one simple movement and adjust.
- If pupils move too quickly or chaotically
- Ask them to slow down and exaggerate the differences between states.
- Use counts or beats to coordinate group movement.
- If the concept seems abstract
- Give a concrete example, like melting chocolate or ice.
- Ask them to think about the particle model: how would the particles move?
- If the group has difficulty coordinating
- Break the movement into stages: first show the solid, then the liquid, then the gas.
- Use visual cues (markers or zones) to guide spacing and formation.
