Let's explore the amazing world of materials in this KS2 Science quiz! It's all about adding special words to your vocabulary to understand the different properties of things, like 'opaque', 'translucent', 'flexible', or 'brittle'.
Properties are like the superpowers of materials. Every material has unique characteristics, and we use them for different jobs. Cork floats but isn't strong enough to build a ship, and glossy paint reflects light but not well enough to be used as a mirror. Knowing words for properties helps us pick the right material for different jobs!
Does your vocabulary include material words? Test your knowledge with this fun KS2 Science quiz on Properties of Materials!

A material's properties might include hardness, flexibility, strength, shininess, softness, etc.
|
Translucent materials may be coloured but you can still see dim shapes through them, like stained glass. Transparent materials are completely see-through, like plain glass

The same material can be flexible or rigid - a copper kettle would be rigid, while copper wiring is very flexible
|
If a material is malleable, its shape can be changed easily

Elasticity is a measure of how well a material returns to its original shape and size after being stretched or compressed
|
Something that is very hard and will break rather than bend is described as 'brittle'
|

Absorbent materials will soak up liquids whilst waterproof materials will not
|
The mass of an object compared to its size is described as its density

If china were a good thermal conductor, you would seriously burn your hands by holding a hot cup of tea

There are lots of reasons we use copper in our electric wires rather than other materials
