Metals and materials

Four lessons that start with questions. Race metals in water and acid, watch carbon pull copper out of its oxide, see a concrete beam crack while a reinforced one holds, and push the layers of atoms in an alloy. Get one wrong and the diagram shows you why. Prefer to read first? Every lesson has animated notes too.

23.1

The reactivity series

How metals react with water, acid and oxygen, and where carbon fits in.

Questions →Notes

23.2

Extracting metals

Ores, carbon, electrolysis, and why gold and copper were used first.

Questions →Notes

23.3

Ceramics, polymers and composites

Three families of materials and their properties: hit them, heat them, bend them and test them.

Questions →Notes

23.4

Choosing materials

Matching properties to uses, alloys, and what happens to materials when we have finished with them.

Questions →Notes
