This lesson is designed for the NEW AQA Trilogy Biology GCSE, particularly the 'Homeostasis' SoW and for higher tier students.

This lesson begins with an outline on the role of the kidney, pupils are asked recap questions on how water enters and leaves the body, which can be self-assessed using the answers provided.

The next slide outlines the main functions of the kidney in controlling water and mineral ion balance, pupils will then need to answer questions on this information. This work can be self-assessed using the answers provided on the following slide.

Pupils will then watch a video on how the kidneys work, pupils will need to answer questions whilst watching the video. Once the video is finished they can assess their own work using the answers provided. To summarise what the students have learnt so far they will then copy and complete sentences, filling in the blanks with the key words provided. Again, the answers for this task are provided for pupils to assess their work.

The next part of the lesson focuses specifically on the release of ADH from the pituitary gland and it's control over the water balance in the body. Pupils are shown a flow diagram of the responses when water levels either rise too high or fall too low in the body. Pupils will then be given a list of statements and will be asked to recreate their own flow diagram to demonstrate this process. This work can then be assessed using the answers provided.
