Drinking water lesson

Class-based lesson for new entrants through to year 8


Your pupils will have the opportunity to discover where their water comes from, how it is treated, and how it gets to their homes and school by participating in a drama activity where they become water drops and go on a journey.

For older students, a content-packed lesson on water treatment can be delivered by Power Point presentation.

They will find out how much water it takes to fill a bath, wash their clothes and clean their dishes as well as how much water is used in Auckland on a daily basis.


Your pupils will be set the challenge of cleaning dirty water. They will use four different filter materials and can investigate which combination/order of materials makes the best filter. 

The pupils who produce the cleanest water will win chocolate fish.

This can be adapted into a teacher-led experimental session for younger pupils with an option for students to make their own water filter at the end of the lesson.

Age group:

This lesson is ideal for new entrants through to year 8.
