6. What happens when salt or sugar is stirred into warm water: it dissolves to form a solution, or it turns into metal?
Material Properties Test · Rigid · Flexible · Waterproof
7. Why is stainless steel used for surgical instruments and kitchen sinks: it resists rust and corrosion, or it dissolves in cold water?
Material Properties Test · Rigid · Flexible · Waterproof
8. Which property describes a material like a rubber band that stretches when pulled and returns to its original shape: elastic or rigid?
Material Properties Test · Rigid · Flexible · Waterproof
9. Which property of metals allows them to be hammered or rolled into thin sheets (such as aluminium foil) without shattering: malleability or solubility?
Material Properties Test · Rigid · Flexible · Waterproof
10. Which property of metals allows them to be drawn out into long thin wires (such as copper wire): ductility or brittleness?
Material Properties Test · Rigid · Flexible · Waterproof
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?
Material Properties Test · Rigid · Flexible · Waterproof
12. Why are cooking saucepans usually made of metal with a wooden or plastic handle: metal conducts heat while wood/plastic is an insulator, or wood melts easily?

Everyday materials & properties
Answers and reasoning. Review before teaching.
1. Which natural plant fibre grows in fluffy bolls and is woven into breathable shirts: cotton or aluminium?
Cotton
Cotton fibres are harvested from cotton plants and woven into fabric.
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. What do we call a mixture of two or more elements, where at least one is a metal (such as bronze made from copper and tin, or steel from iron and carbon): an alloy or a solvent?
Alloy
Alloying combines metals to improve strength, hardness or corrosion resistance.
4. 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.
5. 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.
6. 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.
7. Why is stainless steel used for surgical instruments and kitchen sinks: it resists rust and corrosion, or it dissolves in cold water?
It resists rust and corrosion
Chromium in stainless steel forms a protective oxide film that prevents rusting.
8. 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.
9. 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.
10. Which property of metals allows them to be drawn out into long thin wires (such as copper wire): ductility or brittleness?
Ductility
Ductile materials can be stretched into wire under tension.
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 are cooking saucepans usually made of metal with a wooden or plastic handle: metal conducts heat while wood/plastic is an insulator, or wood melts easily?
Metal conducts heat while wood/plastic is an insulator
Metals transfer heat to the food, while insulating handles stay cool enough to hold.
