I wanted to make a shout out to Sally from Watercare services for her fantastic support. Her lesson was captivating in its content. At first she explained how the waste water was treated and where stormwater went along with why it is important to keep these two systems separate.
Then she moved the class outside for some hands-on experiments around water and geology. She had the students create landforms by arranging rocks and dropping them in plastic sheeting. Then they poured water on them from above to see how rivers and lakes formed and eventually flowed out to the sea. As a final challenge, the students needed to create a landform that could contain a lake of 6 litres of water with no spillage.
Thanks Sally and Watercare Services for a stand-up afternoon.
