Science fairs provide a unique learning opportunity for students, teachers, and members of the community to explore science, technology, and engineering, and to increase public awareness of science and the world we live in.

Though science fairs are generally a competition, they also provide an opportunity for students to display their creative scientific activity beyond the classroom and in the world.

Judging provides a unique opportunity for you to inspire young people who are tomorrow’s technically literate citizens and leaders.


Philosophy of Judging

Judges, members of the scientific, educational, or business community, are essential pieces of this experience. The onus is on the judge to provide an experience that is positive and enriching. The experience of judging contributes directly to the student’s learning experience as well as the judge’s.

All judging interviews should be a positive experience for each exhibitor. Most students enjoy talking about their projects with someone both knowledgeable and understanding. This interaction may directly influence the future scientific/engineering interests of the student. The judge must be encouraging, positive, constructive in criticism, and should discuss future research possibilities with the student.

All students should be treated fairly in the amount of time given to them for interviews, and in the type of comments made. Judging is a challenging task and should be viewed as an individual process with each student. A student’s score should be graded independently, using their knowledge, comprehension, and understanding as indicators of their mark.
