How scientists find out how things work: First a scientist pulls together all the observations about something. Next, he or she thinks up a question that the observations don't explain. Then a hypothesis, that which someone believes to be the correct answer to the question is formed. It must be a statement that can be tested. Next, an experiment is made to test the hypothesis in which everything that happens is written down. Finally the scientist...
