Lesson details
Key learning points
- Combustion requires fuel, heat and oxygen, and will not happen without one of them.
- When a substance reacts to combine with oxygen, this is called oxidation.
- Examples of oxidation are combustion and rusting.
- One of the products of oxidation is always an oxide, but the other products vary.
Keywords
Oxidation - a type of reaction in which oxygen bonds to elements of the reactants
Oxide - a compound containing oxygen that is formed during an oxidation reaction
Rusting - refers to the corrosion of iron or steel, in the presence of water and oxygen
Corrosion - when a metal reduces in size due to a chemical reaction
Common misconception
Pupils often think that all metals rust.
Explain that rust is a form of iron oxide and show pupils other examples of metal oxides, e.g. copper oxide, to show how different they are.

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.
