Lesson details
Key learning points
- The melting temperature of a material is the temperature at which it changes from solid state to liquid state.
- Different materials have different melting temperatures.
- It is hard for scientists to create temperatures high enough to make some materials melt.
- Melting temperatures can be researched using secondary sources of information.
- When carrying out research, more than one source should be used to check that the information is accurate and reliable.
Common misconception
Children may think that only common materials such as ice melt; that materials cannot melt at room temperature or that when something melts, the liquid is a different substance to the original solid.
Children are shown a range of materials with different melting temperatures which range from below to above room temperature. They are taught to refer to materials in a way that highlights the fact that the material is still the same substance.
Keywords
Melting temperature - The melting temperature of a material is the temperature at which it turns from solid state to liquid state.
Solid - A solid has a fixed shape and volume but some solids can change shape when a force is applied.
Liquid - A liquid can flow, has a fixed volume and takes the shape of the bottom of its container.
Degrees Celsius - Temperature is measured in degrees Celsius, often abbreviated to °C.
Secondary sources - Secondary sources are texts, images or objects created using information gathered by others.
