3. Form your hypothesis. Maybe, after all your investigations, you still blame the hot dogs. In your opinion, the hot dogs are responsible for student sickness that afternoon. That’s your theory, your hypothesis.4. Draw your conclusions. You can’t do that until you test your hypothesis, right? If you’re brave, you might run your own experiment and eat one of the suspect hot dogs. Or you can ask your science teacher to run a substance analysis on a hot dog. The fourth step is the time to test your theory and confirm your hypothesis or adjust your conclusion.You decide that you’re not brave, so you don’t eat the hot dog. Your teacher examines the food, but it comes up clean. It’s time to consider a new hypothesis. Since only one person prepared the hot dogs, and he didn’t touch the hamburgers, you shift your suspicions to him. To test your new theory, you spy on him. Sure enough, you see him cough without covering his mouth. The man confesses that he just got over the flu. Case solved.
