The Calgary High School Science Bowl (YYCSB) is a modern format of science competition established in Calgary, Alberta. Competitors ranging from Grade 9-12 gather into teams of 4 and come to the Central Library for a one-day event, to take part in a brain-stimulating contest that includes both questionnaires and a construction challenge. Problems range from Grade 9 levels all the way up to Grade 12. The first annual YYCSB will be held on April 6, 2019.
