Activity Introduction

Quick summary: Students investigate what happens when people’s activities result in water pollution. Pollution on land is simulated with the addition of easily obtained materials in a clear bowl of water. Students make links with retaining healthy waterways with preventing polluting substances from reaching them.

Key lessons and understandings of activity:

  • Many substances can pollute rivers and other waterways.
  • Governments have restrictions to prevent waterways from becoming polluted.
  • Things that we as individuals do can contribute to pollution if we dispose of things inappropriately.

Teacher Preparation

This activity requires a considerable amount of preparation (see Preparation Sheet below introduction).

You will be reading ‘the story of our river‘ to your students and while you read you will be demonstrating the causes and results of water pollution by pouring various ‘pollutants’ into a tub of water that represents your river.

Introduce topic

Briefly introduce your students to the concept of Australia being the driest inhabited continent.

Discuss with them how, in such a dry place, water is extremely precious and that many ecosystems that already are stressed from lack of water are also under threat of pollution. All of us living within water catchments contribute directly or indirectly, significantly or not so significantly to the degradation of our waterways, often without realising the relationships and impacts that humans make.

Key words

Following this, briefly discuss the meanings of some of the key words that will be raised in this activity. These w

The story of our river

This is the story of a very special river – our river. Our river takes its long journey from the mountains where the rain runs off the slopes and travels a very long way, weaving through cities, towns, valleys and farms until it reaches the sea.

One of the first places our river visits after it has left the mountains is a power station that generates electricity for our region. It burns large quantities of coal and releases pollutant gases into the atmosphere. These pollutants combine with moisture in the atmosphere to produce acid rain. Rainfall carries these acids back to the Earth’s surface where it flows into the river.

The river gathers momentum as it travels down the hills. The river continues its journey towards the sea through farming country where, recently, some crops were fertilised. Afterwards it rained on the farms and the rain run‑off from the fields went straight into our river bringing with it some of the fertiliser.

The farm next door is a p
