The lesson starts by recapping on the role of negative feedback systems in homoeostasis, pupils will need to complete a flow diagram to demonstrate how a negative feedback system works. This can be completed in their books and marked using the answers provided.

The next part of the lesson focuses on thyroxine and adrenaline, pupils are reminded of the roles of each of these hormones and they will then be given some extra information (provided) using which they will need to answers some questions on the topic. Detailed answers are provided for these questions so that pupils can check their work by either peer or self-assessment.

The next activity is a ‘who am I?’ task, pupils will have covered a range of hormones by this point and will now be given a set of descriptions about different hormones, they can discuss with their partners and try to identify the names of each of them. Once completed this work can be assessed.

The final task is an exam question about hormones, with the mark scheme provided.

The plenary task is for pupils to write a text message to a friend describing what they have learnt in the lesson today!
