What is the Ottawa Regional Science Fair?

The Ottawa Regional Science Fair (ORSF) is organized and run by a volunteer organization to encourage students in the Ottawa-Carleton Region, from grades 7 to 12, to research, develop, and present projects in the fields of science and engineering. Students from both public and private schools in the region are invited to enter projects in the fair.

Why judge at the ORSF?

We’re looking for judges – people with a strong background in science, technology, engineering, or mathematics (STEM) – who are willing to spend a few hours sharing their expertise, enthusiasm, and encouragement with students and providing feedback on their projects. If that sounds like you, we’d love to have you on our team.

Judges love the experience. They find the students inspiring, the projects impressive, and the colleagues they meet a pleasure to work with. Everyone at the fair is passionate about science in one way or another. We hope you’ll join us.
