Pupils will firstly come up with a mind map of ideas about why water is such an important resource, they can discuss with their partner and write their ideas in their books. Some of the reasons can then be revealed via the PowerPoint presentation and pupils can assess their work - making corrections where necessary.

Pupils are then shown a quick recap of the stages involved in the water cycle, before beginning to look at the treatment of fresh water and purification of salt water. Students will be given a worksheet of questions, around the room will be information sheet on how fresh water is turned into potable, drinking water and how sea water is purified. Pupils will need to read the information posters to answer their questions, this work can then be self-assessed using the mark scheme provided.

The next part of the lesson will focus on waste water treatment, pupils will watch a video on the steps involved with sewage treatment. Pupils will answer a set of questions whilst watching the video, this work can then be self-assessed using the answers provided.

The final task is for pupils to complete an exam-style question on this topic, they can answer in their books and either self or peer assess using the mark scheme provided.
