When To Use
A scientific theory is a well-tested, broad explanation of a natural phenomenon.In everyday life, we often use the word theory to mean a hypothesis or educated guess, but a theory in the context of science is not simply a guess—it is an explanation based on extensive and repeated experimentation.
