Lesson details
Key learning points
- Iron is alloyed with other metals to produce steel alloys.
- Copper is alloyed with other metals to make multiple useful alloys.
- Gold, aluminium, and magnesium all form useful alloys with other metals.
Keywords
Alloy - A mixture of two or more elements, where at least one element is a metal.
Steel - An alloy of iron that contains specific amounts of carbon and may contain other metals.
Carat - A unit for measuring the purity of gold.
Brittle - A substance that has the ability to break up easily.
Common misconception
Pupils often find it difficult to apply what they have learnt about alloys when asked about an unfamiliar one, or when provided with a table of data.
Provide pupils with a range of different examples of alloys. Give them plenty of practice of comparing the properties of the alloy with those of the pure metal.
Equipment
None required.
