NEW AQA Trilogy GCSE (2016) Chemistry - Atom Economy HT

This lesson is designed for the NEW AQA Trilogy Chemistry GCSE, particularly the ‘Chemical calculations’ SoW, specifically designed for higher tier ‘chemistry only’ students.

For more lessons designed to meet specification points for the NEW AQA Trilogy specifications for Biology, Chemistry and Physics please see my shop: https://www.tes.com/teaching-resources/shop/SWiftScience

The lesson begins with a video on atom economy, pupils will answer a set of questions whilst watching the video which can be assessed using the answers provided.

Pupils will then be taken through a worked example, step-by-step, to show how you are able to calculate atom economy once you know the desired product of a given reaction. Pupils will then need to use this worked example to come up with their own step-by-step checklist of tasks which need to be completed to work out the atom economy of a reaction. This can be checked against a list provided on the following PowerPoint slide.

Pupils will then be given a list of questions on atom economy, they will need to show their working for each of the problems. Once the task has been completed pupils can check their work against the answers provided on the PowerPoint presentation.

The next task is an exam-style question on atom economy, pupils should complete this in their books (and on their own, in silence for those higher ability classes), once complete this can be assessed against the mark scheme.

The last task is for pupils to come up with five exam questions on atom economy, including a mark scheme for each question.
The plenary task is for pupils to complete one of the example sentences, e.g. ‘I have understood this…’, ‘I still don’t understand…’.

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 :)
