This is a lesson which meets specification points within the WJEC GCSE ‘The Sciences’ Double Award (2026) spec, specifically from Unit 2.3 - Rate of reaction (Chemistry).

The lesson starts with an overview of the key vocabulary which students will be learning and using this lesson. Students can stick their key word lists into their books before the lesson begins.

This lesson begins with a video on catalyts, pupils will need to watch this and use the information provided to answer a set of questions. This work can then be self-assessed using the answers provided on the PowerPoint. This is followed by students sketching a reaction profile diagram into their books to show the effect of a catalyst on the activation energy of a reaction.

In the next task pupils will be given some information on catalysts, they will need to read through this and use this to complete a place-mat of questions. Once completed, students can either self-assess or peer-assess their work using the mark scheme provided.

Pupils will now work through a set of levelled questions on catalysts using data which is provided, pupils can then self-assess their work using the answers provided on the PowerPoint.

The final task is a true or false activity, pupils are given a set of statements which they need to decide are true or false. They can write their answers down on mini white boards so it is easier to assess the whole class.

The plenary activity requires pupils to talk to their partner, for a few minutes, about what they have learnt in the lesson today.

All resources are included at the end of the presentation. Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)
