Practice - Materials and Their Properties - 01

Hello young scientists! Are you ready to test your knowledge on different properties of materials we encounter daily? This fun and stimulating quiz will challenge your understanding of concepts like hardness, transparency, conductivity and more! Let's dive into the realm of materials and see how much you know!
1.
What characteristic describes a material that cannot change its shape easily?
Elastic
Rigid
Malleable
Flexible
Rigid materials are hard and do not change shape easily. An example is a metal rod.
2.
What can you call a material that soaks up water?
Dense
Translucent
Rigid
Absorbent
Absorbent materials soak up liquid. Things like paper towels, sponges, and certain fabrics can absorb water.
3.
Which of these is an example of a transparent material?
Wood
Metal
Glass
Brick
A transparent material is one through which light can pass easily. An example of this is glass!
4.
Which is the term for a material that can be hammered into thin sheets without breaking?
Flexible
Malleable
Fragile
Breakable
Malleable is the term used for materials that can be pounded into thin sheets without breaking. Like gold and aluminum!
5.
Which of the following materials is a good conductor of heat?
Paper
Metal
Glass
Rubber
Metal is a good conductor of heat. That's why it's used in pans!
6.
What characteristic makes a material brittle?
It can be stretched
It can be bent
It shatters when hit
It can be squeezed
Materials are classified as brittle if they shatter when struck or under high pressure, like glass or dry clay.
7.
What is it called when a material can return to its original shape after being stretched or compressed?
Resilience
Elasticity
Density
Rigidity
Elasticity is the ability of a material to return to its original shape after being stretched or compressed, like a rubber band.
8.
Which material has high density?
Cork
Aluminium
Lead
Plastic
Lead is a high density material. It's much heavier for its size compared to many other materials.
9.
What does the term 'opaque' refer to?
A material that lets light pass through
A material that smells
A material that has no odour
A material that blocks light
Opaque materials do not allow light to pass through them. Example: wood, metal, etc.
10.
Which of the following materials is an insulator?
Copper
Iron
Aluminium
Rubber
Rubber is an insulator. It does not allow electricity to pass through it!
