Eduqas GCSE Design and Technology materials and their properties overview quiz quiz

Its weight in grams per square metre

Its overall thickness measured in millimetres through the sheet

The total surface area of the sheet measured in square metres

How dark or saturated the printed colour appears on the surface

It is a heavy, solid block that resists being squashed by stacking

Its fluted (wavy) middle layer absorbs impacts and cushions the contents

It is completely waterproof and keeps all moisture away from the contents inside

It cannot be recycled, so it stays strong and is never reused

Fast-growing coniferous (evergreen) trees

Manufactured fibres glued into board

Broadleaved (deciduous) trees

Pulped and pressed recycled paper

Mahogany

Redwood

Western cedar

Plywood

It contains iron, so it rusts and is usually magnetic

It has a bright, shiny surface that reflects light strongly

It is very light in weight compared with other common metals

It is always an alloy of two or more different metals mixed together

A single pure metal that has not been mixed with anything else at all

A mixture of two or more metals (or a metal and another element) to improve properties

A synthetic plastic polymer that is moulded into shape by careful heating and then cooling

A natural fibre spun from plant or animal sources into yarn

It sets hard permanently on first heating and can never be softened or reshaped afterwards

It only chars and burns away without ever softening or melting

It softens and can be reshaped, and can be reheated and reshaped again

It dissolves completely in water and turns into a runny liquid

They are far too soft and runny to ever hold a fixed shape when warm

They are natural materials that come straight from plants and animals

They contain iron, which locks the moulded shape firmly in place once it has fully cooled down

They set hard permanently on first curing and only char or burn if reheated

Hardness resists scratching and wear; toughness resists impact and cracking

They mean exactly the same thing and can be used interchangeably for any material

Hardness resists impact and cracking, while toughness resists scratching and wear

Both simply describe how heavy a material feels when you lift it up

Malleability

Ductility

Hardness

Toughness

It makes the shirt much heavier and stiffer so it holds a structured shape

It removes all stretch so the fabric stays completely rigid when worn

It combines the comfort and breathability of cotton with the strength and quick-drying of polyester

It makes the shirt so warm and insulating that it is suitable only for cold winter weather outdoors
