Throughout this lesson series, Students make a list of all the various water usages in their school and start to consider, 'where does the water come from before reaching their school?'
Water sources will be shown via images and online resources including the Powerpoint in Unit Resources. Australian water storage and sources will be compared to a case study in Tanzania in which people had walk to collect their water supply each day for drinking. Finally, students will make a solar still model to conduct an experiment in which they can remove clean drinking water from salt water and dirty water.
Extra lesson ideas include colouring in the water sources sheet and playing the water sources game.

- Collect water from a dripping tap and measure how much is lost over the period of one hour.
- Write their measurements in a table and predict how much water is lost over one school day.
Evidence of Learning
Can the student:
- Accurately measure lost water and predict the amount of water lost over the period of a school day.
Example Learning Sequence
- Ask students to identify places where they observed a leaking, dripping or broken tap during their water audit in the previous lesson.
- Explain to students that they will be measuring the water lost by the tap over the course of one minute and then using digital technology to calculate the water loss over one hour, one day and one year.
- Ask students to draw a table into their books to record their measurements and calculations.
- Take students to their leaking taps and put the cup under it for one minute, using a timer. Measure the amount of water collected by pouring it into a measuring container. Use digital technologies to calculate the water loss over one hour, one day and one year.
- Discuss with students why it is important to reduce the amount of leaking taps in the school to conserve water.
