Science Competitions for High School Students

Science competitions come in two shapes, and they ask for completely different work. Exam-based contests test how much biology, chemistry, or physics you know. Project-based ones — science fairs and research showcases — ask you to design an investigation and present results, sometimes over an entire school year.

Pick based on what you actually enjoy. If you like problem sets and fast feedback, the exam side is a better fit. If you'd rather spend months on one question you chose yourself, the project side is worth the commitment, and it overlaps naturally with finding a research mentor.

Both kinds usually need a teacher or school sponsor to register or submit on your behalf, so the first step for most of these is talking to a science teacher before the deadline, not after.
