Lesson details
Key learning points
- When it melts, a substance changes from the solid state to the liquid state.
- When it freezes, a substance changes from the liquid state to the solid state.
- At temperatures below its melting point, a substance is in its solid state.
- At temperatures above its freezing point, a substance is in its liquid state.
- The melting point and freezing point of a pure substance are the same temperature.
Keywords
Liquid state - Substances in the liquid state will take the shape of their container.
Solid state - Particles in a substance in a solid state are in a fixed position and can only vibrate.
Melting point - The melting point of a substance is the temperature at which it changes from a solid state to a liquid state.
Freezing point - The freezing point is the temperature at which a substance changes from a liquid state to a solid state.
Common misconception
Some students can't understand that substances can change from one state to another state.
Ensure that the language used is solid state, liquid state and gas state, not solid, liquid and gas.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
