Raingardens: managing our stormwater (Years 7-8)


What's a raingarden? In this lesson plan, explore how they can protect rivers and creeks from stormwater pollution, and how you can build one.

In unbuilt areas, stormwater that is not infiltrated into the soil will flow over the ground. If there are agricultural chemicals and other pollutants on the ground, this gets carried along with the stormwater.

In urban areas, rainwater from the roof of your house, driveways, roads and footpaths is carried away through drains and pipes. It can also carry with it anything that is lying in the soil or drains – cigarette butts, cans, paper or plastic bags, detergents, oil, fertilisers, leaves, garden clippings, animal droppings and sediment from soil erosion, building sites and unsealed roads.

All of this can end up polluting our waterways.
