Future of London's water

This resource can be used to organise a class debate on the various solutions to London’ s potential water shortages and the challenge of maintaining the system as a whole. Students will take on roles of various engineers and scientists as well as local members of the community to conduct a debate on possible solutions.

Success criteria can be developed by the class for a successful conclusion to the debate and their ideas presented to the class either verbally or via a summary poster.

Success criteria might include:

• Everyone is involved in the group discussion and group presentation
• It is clear who (from role cards) might support or be opposed to the solution
• Science ideas are included in the table for each solution, for example:

1. How does the solution conserve natural water supplies?

2. How might this solution reduce human impact on the water cycle or environment in general?

3. What chemical processes might be involved? e.g. filtering, separating etc.

4. What energy savings might be involved in this solution?

5. What risks might be involved with this solution?

6. What are the benefits of this solution?

7. Ideas are ranked and reasons clearly given in group presentation
