The Scientific Method Observation Hypothesis Test

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.
