  6. TheScientific Method

  7. Hypothesis: A trial explanation of certain facts that provides a basis for further experimentation. Theory: Well-established hypothesis. An explanation of the general principles of certain phenomena with considerable evidence or facts to support it. Law:Statement of natural phenomena to which no exceptions are known under the given conditions. A law is not an explanation.

  8. Steps

  9. 1. Collect facts or data that are relevant to the problem or question at hand. This is usually done by experimentation. 2. Analyze the data to find trends (regularities). 3. Formulate a hypothesis that will account for the data and that can be tested by further experimentation.

  10. 5. Modify the hypothesis to ensure compatibility with the experimental data. 4. Plan and do additional experiments to test the hypothesis.
