Properties and Uses of Materials
This lesson introduces Year 5 students to the physical properties of materials. Students will learn to categorise materials based on how they act (e.g., conducting heat) and how they look or feel (e.g., transparency and hardness), linking these properties to real-world applications.
Learning objectives
- Identify and compare the properties of everyday materials, including hardness, solubility, and transparency.
- Distinguish between thermal and electrical conductors and insulators.
- Explain why specific materials are chosen for particular uses based on their properties.
- Recall that some materials respond to magnets while others do not.

Key vocabulary
- Conductor
- A material that allows heat or electricity to pass through it easily.
- Insulator
- A material that does not allow heat or electricity to pass through it.
- Transparent
- A material that allows light to pass through so objects behind can be seen clearly.
- Opaque
- A material that does not allow any light to pass through.
- Solubility
- The ability of a solid to dissolve in a liquid.
