Youth Science Canada in updating the program we use for registration. We anticipate that it will be available

Judge volunteers are a critical part of our science fair; helping to evaluate student projects and provide constructive feedback so students can improve their science and presentation.  Prepare yourself to be amazed by these young scientists! Teachers, scientists, community members and students all are welcome.
