Science Fair for Young Children (SFYC) is a project designed for primary school students, and about 200,000 participants have taken part in this initiative since 2006, at school, regional and national levels. The ex-SYFC students are in secondary school now and are collectively known as the SFYC Alumni. For the benefit of these Alumni, ASTI organised an inventing competition named the Young Inventors Challenge (YIC) with the Theme “Green Inventions: Ideas on Sustainability”.
