Expo-sciences des 4-H du Canada
Le monde qui vous entoure est source de curiosité? Avez-vous une théorie à mettre à l’essai ou une solution à peaufiner? L’Expo-sciences des 4-H du Canada est l’occasion idéale pour les membres des 4-H d’explorer, d’expérimenter et de découvrir!
Chaque année, les membres des 4-H de la 7e à la 12e année du secondaire (secondaire I à secondaire V au Québec) ou au CÉGEP, planifient, effectuent des recherches, complètent et soumettent des projets scientifiques — seuls ou en groupes de deux — qui seront évalués virtuellement dans l’espoir de passer à la deuxième ronde en personne. Les finalistes de la deuxième ronde participeront à l’Expo-sciences pancanadienne!
Do you have a curiosity about the world around you?
The 4-H Canada Science Fair is the opportunity for you to explore, experiment, and discover! As part of our 4-H Canada Science Fair, 4-H youth plan, research, complete, and submit science projects - independently or as pairs - to be judged virtually in the hopes of moving to our in-person round and ultimately to the Canada-Wide Science Fair.

How does the 4-H Canada Science Fair work?
Either by yourself or with another 4-H’er, you’ll explore a topic of your choice to create your very own 4-H Canada Science Fair project. You’ll have the opportunity to Learn To Do By Doing (and have a ton of fun!) while planning, researching, building, experimenting, testing, and analyzing your science fair project.
