4-H Canada Science Fair

Do You Have a Curiosity about the World around You?

The 4-H Canada Science Fair is an opportunity for youth to explore, experiment, and discover as they plan, research, complete, and submit a science project either independently or with a partner! Youth will be judged virtually in the hopes of moving to our in-person round and ultimately, the Canada-Wide Science Fair.
