Three myths of Science Olympiad coaching:
1. You have to have a background in science - No, you just need to be willing to support the student's desire to have a team.
2. You have to do it alone - No, a co-coaching system of 2 or 3 adults is best.
3. You have to know everything about the events - No, you just have to be willing to help the students learn about a topic. You may learn something interesting too.
