5. The Scientific Method
Observation
Hypothesis
Test

6. The scientific method is a systematic approach to research
A hypothesis is a tentative explanation for a set of observations
tested modified
A law is a concise statement of a relationship between phenomena that is always the same under the same conditions.
A theory is a unifying principle that explains a body of facts and/or those laws that are based on them.
