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.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
