What you’ll learn

CeramicsUnderstand that ceramics are made from clay or minerals shaped and fired, and that they are hard, brittle, heat-resistant insulators.Ceramics are made from clay or other minerals that are shaped and then fired at high heat until they harden. They are hard, brittle, and resist heat and chemicals, and they act as electrical insulators. Pottery, bricks, glass and tiles are all ceramics.
PolymersUnderstand that polymers are long chains of repeating monomers, that most plastics are polymers, and that they are light and flexible.Polymers are made of very long chains of small repeating units called monomers. Most plastics, such as polythene, PVC and nylon, are polymers, and they tend to be light, flexible, waterproof and good insulators. Some polymers, like rubber and DNA, are natural.
CompositesUnderstand that composites combine two or more materials for better properties, using examples like concrete, fibreglass and carbon fibre.A composite is two or more different materials combined so the result is better than either alone, usually a matrix plus a reinforcement. Concrete combines cement with gravel and sand and sometimes steel, fibreglass sets glass fibres in plastic, and carbon fibre is strong yet very light. Composites let us build materials with exactly the properties we need.

Questions this course answers

How are most ceramics made?

Ceramics are made from clay or other minerals that are shaped and then fired in a very hot kiln to harden them.

Which set of properties best describes a ceramic?

Ceramics are hard, brittle and resist heat and chemicals, and they act as electrical insulators rather than conductors.

What is a polymer?

A polymer is built from very long chains of small repeating units called monomers joined together.

Which of these materials is a polymer?

Most plastics, including polythene, are polymers because they are made of long molecular chains.

What makes a material a composite?

A composite combines two or more different materials so the result has better properties than either material alone.

Concrete is a composite because it combines which materials?

Concrete is a composite of cement mixed with gravel or sand, often reinforced with steel, which is stronger than any of those parts alone.
