Comparing and grouping solids, liquids and gases
I can compare and group materials according to whether they are in solid, liquid or gas state.
Lesson details
Key learning points
- Solids, liquids and gases have different properties
- We can observe and classify materials as solid, liquid or gas state
- Some objects are made from different materials, so can have properties of more than one state
- Some materials are difficult to classify because they appear to have properties of both solids and liquids
Common misconception
Some solids can be poured and take the shape of their containers and therefore are liquids. A material is not the same material after it has been crushed.
Teaching slides and investigation will help children consider the difference between one solid particle of a material and a pile of particles which behaves together like a liquid.
