A material that is shiny, hard and a good thermal and electrical conductor.

Long chained molecules formed by joining together monomers.

A mixture of two or more elements where at least one element is a metal.

A material made from two or more different types of materials. When combined they create a new material with improved properties.

Materials and composites: including metals, ceramics and polymers

Science

Structure of polymers

The reactivity series for metals

Chemical reactions: displacement of metals

Catalysts

In the Using Earth's Resources unit, pupils will build on their knowledge of materials to explore the extraction and purification of metals, life cycle assessments, and recycling.

In the Acids and Bases unit, pupils learned about the properties of acids, bases, alkalis, and the neutralisation reaction.

This unit examines the varying properties of elements, the reactivity series, and the role of carbon in metal extraction. It also explores catalysts and the properties of ceramics, polymers, and composites. Emphasis is placed on evaluating risks, using appropriate techniques, and interpreting data.

Materials

Long-chained molecules formed by joining together monomers.

A pulling force that keeps particles close together.

A product that is manufactured from natural resources.

A substance that is added to a polymer to increase its flexibility.

A chemical bond between different chains of atoms in a polymer.

Shows metals placed in order of reactivity with the most reactive metal at the top.

When bubbles of gas are produced in a liquid; another way of saying a liquid is fizzing.

A type of reaction in which energy is transferred from the reactants to the surroundings e.g. combustion.

A displacement reaction occurs when a more reactive element takes the place of a less reactive element in a compound.

A compound comprising of a metal and a non-metal.

Formed when a substance is dissolved in water.

A rock that contains metals or metal compounds. Metal can be extracted from its ore.

a chemical that speeds up the rate of a reaction without itself being used up

a biological catalyst that speeds up reactions in living things

when atoms are rearranged to make new products and changes can be observed e.g. bubbles of gas forming
