Upper Canada College Grade 7 student Kevin Liu received a bronze medal in the junior age group at the Canada-Wide Science Fair in Regina, Sask. in May 2017.
There were approximately 10 gold, 20 silver and 35 bronze medals awarded in the junior category, in which 160 Grade 7 and 8 students took part.
Liu spent about 40 hours working on his project. It dealt with pollution levels in the Credit, Grand, Nottawasaga and Humber river systems, which all originate from the same area near Mono, Ont. but flow through distinct areas and end in various places.
Liu found that pollution levels were higher in areas with higher populations along a river’s watershed and that the pollution levels of the rivers impacted the pollution levels of lakes. He also discovered that conservation areas in Ontario’s Greenbelt helped cleanse river waters.
Liu says he enjoyed his experience at the Canada-Wide Science Fair, which took place from May 14 to 20.
“The projects and all the activities there were very captivating and inspiring,” he says.
“If one has an idea, no matter how seemingly ridiculous, one should nurture and develop that idea. Anything can be adapted into something very valuable and impactful.”
Liu earned the right to go to the national event by winning a gold medal at the April 1 Toronto Regional Science Fair. He also received the Water Environment Association of Ontario Award for “demonstrating exceptional research, knowledge and scientific thought on a water environmental related topic” at the regional event.
