Document Summary
It is a way of finding answers to empirical questions that is questions that can be answerd by observing the world and measuring aspects of it. It has 4 basic goals: describing what happens, predicting when it happens, controlling what causes it to happen, and explaining why it happens. Scientists use the scientific method to answer these questions. The scientific method depends on theories, hypotheses, and research. Scientific method is made up of an interaction between theories, hypotheses and research. A theory is an explanation/model used to e xplain how something in the world works. It explains prior explanations and makes predictions about future events. A theory should generate a hypothesis, which is a specific, testable prediction about the outcome thatw would best support the theory. If the theory is accurate, then the hypothesis should be supported. Once you develop your hypothesis, you have to do research which involves the collection of data (objective information that tests the hypothesis).
