Adaptive teaching
Pupils needing extra support
Could investigate melting using real ice cubes (which are easier to observe melting) and only hot and cold water, allowing for less data collection.
Pupils working at greater depth
Could be provided with a list of materials (a hot water bottle, thermometer, foil cake cases, butter, chocolate, ice and an iron nail) to discuss and plan (on a whiteboard) how to compare the melting points of the different materials.

Knowledge outcomes
- I can describe the conditions needed for melting (heating above the melting point of the material) and freezing (cooling below the freezing point of the material).
- I can describe the property changes as a material melts from having a fixed shape to flowing and taking the shape of its container.
- I can describe the property changes as a material freezes, from flowing and taking the shape of its container to having a fixed shape.
- I can name the start and end states when materials melt (solid to liquid).
- I can name the start and end states when materials freeze (liquid to solid).
