This week, Edmonton is hosting the Canada-Wide Science Fair, where outstanding students from Grades 7 to 12 across Canada are presenting innovative STEM projects. Reni Barlow, executive director of Youth Science Canada, emphasized the wide range of challenges addressed by these projects, which include topics such as aerospace, energy, environment, climate change, natural resources, and health. Notable projects include a device attached to a robotic turtle that detects microplastics in water and a new method for measuring pulse rates in individuals with darker skin tones. Jainika Joshi, a Grade 9 student from Edmonton, is showcasing a device that analyzes breath concentration to identify oral diseases, aiming to promote awareness of oral health issues. The fair features 344 projects and offers more than $2 million in awards, primarily in the form of university entrance scholarships. The event is open to the public at the Edmonton Expo Centre until Saturday, providing a platform for young innovators to display their problem-solving skills in science and technology.
