PROPERTIES OF MATERIALS
Materials have different properties that make them useful for different jobs. Here are some properties that materials have.
Transparent materials do let light through (you can see through them). Opaque materials do not let any light through (you cannot see through them).
Waterproof
Waterproof materials do not let water through and do not soak up water.
Absorbant
Absorbent materials soak up water and let water pass through them.
Strong or weak
Strong materials are very difficult to break. Weak materials break easily.
Flexible
Flexible materials are easy to bend.
Rigid
Rigid materials are difficult to bend.
Hard
Hard materials are difficult to scratch.
Conductors
Some materials are good conductors of heat. This means heat can travel through them easily.
Some materials are good conductors of electricity. This means electricity can travel through them easily.
Insulators
Some materials are insulators of heat. This means they do not allow heat to travel through them very easily. Some materials are insulators of electricity. This means that electricity cannot travel through them.
