4-H Canada Science Fair

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. 

The 4-H Canada Science Fair is open to 4-H’ers in grades 7 to 12 or enrolled in CÉGEP.

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. 

Virtual Round

You’ll develop and submit your project by Jan. 27, 2023 as part of the virtual round. Your project then will be judged virtually between Jan. 30 and Feb. 10, 2023. 

Second Round

The top projects from the virtual round will then move on to the in-person round in Alberta from March 9-12, 2023, where four winning projects will be selected.
