Read the quick preparation notes, then start when you are ready.
SkillrHub quiz practice is built for curriculum-aligned revision with answer feedback and a clear review path.
Quick preparation
- Students learn to investigate the observable properties of solids and liquids and how adding or removing heat energy leads to a change of state. They use the visual model, precise vocabulary and evidence to explain and apply the concept.
- Use this routine: Observe → Model → Investigate → Record → Explain.
- Watch for liquids have no volume: Liquids have a definite amount even though shape changes.
