PATRICK BAKER (TOP, YEAR 9) AND LEONARDO WANG (LEFT, YEAR 9) COLLECT MICROPLASTICS FROM A SAMPLE WHILE FELIX MACDONALD (RIGHT, YEAR 8) DETERMINES THEIR CLASSIFICATION From the iconic Yarra River to the small creek in your local park, Melbourne certainly has a complex system of waterways. It’s common for many major new housing projects in Australia to include the central feature of a lake or wetland. These oases are scenic, and pleasant features for residents — and they frequently take centre stage in real estate advertising brochures. But the serene lake surfaces may mask a serious risk. How good is the quality of the water? Are they sinks for pollution, potentially posing risks to public health and local fauna? Or do they play a key role in removing the dross of urban life before it spills into Port Phillip Bay? A group of Scotch Years 8 and 9 boys wants to find out. The boys are participating in WATERisLIFE, a global project that calls on young people to tackle emerging water issues around Australia and worldwide. The boys have designed a research project to survey water quality in urban Melbourne, in particular tracking chemical contaminants and microplastics from their sources in our suburbs as they flow towards the bay. If the amount of contamination in the bay were to rise – even slightly – our beautiful Port Phillip Bay could change from striking blue to bright green over the next century. In many ways the problem is very small … tiny pieces of plastic, called microplastics, that make their way from stray rubbish and commercial activity into rivers and eventually onto our beaches and into our aquatic ecosystems. At weekends, equipped with a lab in a bucket, the boys are collecting samples in the field to answer their questions. Their findings will allow them to take a peek at Melbourne’s pollution scorecard. These will be submitted to the WATERisLIFE conference in June hosted by St Stephen’s Episcopal School in Miami, USA. Looking further ahead, the boys will be key participants in the very first WATERisLIFE conference to be hosted in the southern hemisphere, right here at Scotch. WATERisLIFE enables students to collaborate globally to achieve the aims of the United Nations Sustainable Development Goals, and ensure that clean, healthy water is available everywhere for people and the environment.
