Activities
Outcomes
Children:
Discuss with the children what makes water dirty. Ask the children to collect water samples and examine their smell and appearance (BUT NOT TASTE) and carry out experiments to find out how water may be cleaned, eg boiling, filtering. Ask them to consider whether there are things in the water that cannot be seen.
Ask the children to find out from the library about times when people did not have clean water and how changes were brought about. They may also find out what is meant by 'usable water' and the comparative importance of a plentiful supply of clean water.
Visit a sewage treatment plant.

Literacy: these activities can be used to highlight the purpose of research and to emphasise the importance of establishing a 'brief' for the kinds of note to be made.
