Everyday materials & properties
Answers and reasoning. Review before teaching.
1. Which property describes a material like ceramic or glass that shatters easily when dropped: brittle or flexible?
Brittle
Brittle materials crack or shatter under impact rather than bending.
2. Which material is harder in a scratch test: diamond or chalk?
Diamond
Diamond is the hardest known natural mineral (10 on the Mohs scale) and easily scratches chalk.
3. Which property of metals allows them to be hammered or rolled into thin sheets (such as aluminium foil) without shattering: malleability or solubility?
Malleability
Malleable materials can be shaped by hammering or rolling without cracking.
4. What happens when salt or sugar is stirred into warm water: it dissolves to form a solution, or it turns into metal?
It dissolves to form a solution
Salt and sugar are soluble in water, dispersing evenly to form a clear solution.
5. Which material is a good conductor of electricity and is used inside electrical wires: copper or rubber?
Copper
Copper is a ductile metal with high electrical conductivity; rubber is used for the outer insulating sheath.
6. Why is expanded polystyrene or woollen fleece used as thermal insulation: trapped air pockets slow down heat transfer, or it generates electricity?
Trapped air pockets slow down heat transfer
Still air is a poor conductor of heat, so materials that trap air insulate well.
7. Which material is attracted to a magnet: iron (steel) or wooden pine?
Iron (steel)
Iron and steel are ferromagnetic metals; wood is non-magnetic.
8. Which material comes from the fleece of sheep and is spun into warm yarn: wool or nylon?
Wool
Wool is a natural animal fibre that traps air for insulation.
9. Which property describes a material like a rubber band that stretches when pulled and returns to its original shape: elastic or rigid?
Elastic
Elastic materials deform under force and spring back when released.
10. Which property describes a material like a sponge or cotton towel that soaks up water: absorbent or waterproof?
Absorbent
Porous materials like sponges and cotton towels absorb liquids into tiny spaces.
11. What do we call a material like frosted glass that lets some light through but scatters it so you cannot see clearly through it: translucent or opaque?
Translucent
Translucent materials transmit diffuse light without forming a clear image.
12. Why is brick or stone chosen for building outer walls: it is strong, rigid and weather-resistant, or it is soft and soluble?
It is strong, rigid and weather-resistant
Masonry materials bear heavy loads and withstand rain and wind.
