Simply watching something grow is not a science project. For it to be a science project, you would have to keep records concerning the growth of the onion. You would need to record how it grew each day. You would need to record the temperature. Science involves keeping careful records. Better yet, you could grow several onions, one with no fertilizer and others with different types of fertilizer. Science involves record keeping not just observation.
