NDQ_000001 | Steps of the scientific method include all of the following except | a. doing background research, b. constructing a hypothesis, c. asking a question, d. proving a theory | d | Lesson: the nature of science
Scientific Method:
The scientific method is a set of steps that help us to answer questions. When we use logical steps and control the number of things that can be changed, we get better answers. As we test our ideas, we may come up with more questions. The basic sequence of steps followe... |
