Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Oxidation is the loss of electrons and reduction is the gain of electrons.
- Half equations can be written to show which species are oxidised and which are reduced.
- Ionic equations can be written for displacement reactions.
Keywords
Oxidation - Oxidation is a type of reaction in which a substance gains oxygen or loses electrons.
Reduction - Reduction is a type of reaction in which a substance loses oxygen or gains electrons.
Half equation - A half equation is a chemical equation used to show the electrons lost in oxidation or the electrons gained in reduction.
Redox reaction - A redox reaction is a reaction where both reduction and oxidation occur.
Common misconception
To show the spectator ions in an ionic equation.
Spectator ions are ions that remain the same throughout a reaction. They are not included in the ionic equation.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
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.
