Explain the criteria for categorizing phenomena as science (consistent, observable, natural, predictable, testable, and tentative).

Consistency: Consistency is the property of the phenomena where the result of the observation or experiment should be consistence. The degree of the variation between the observation should very low. Observable: The outcome of the result of the experiment should be observable and the result should be record able.Natural: For the happening of the event, it should be explainable with the reference of the natural events. Predictable: The event should be able to predict that can be explained on the basis of the naturally occurring event.Testable: the cause of the natural event should be able to tested on the basis of variable environment in controlled environment to draw the different result and a conclusion based on the result.Tentativeness: the scientific theory should be such that it could be tested upon. With the development of science, the theory should be modifiable and even proven wrong.
