Verified step by step guidance1
Begin by understanding the definition of a scientific theory. A scientific theory is not a mere guess or hypothesis; it is a well-substantiated explanation based on a body of evidence.
Recognize that a scientific theory is different from a scientific law. A law describes a phenomenon, often mathematically, while a theory explains the underlying reasons for the phenomenon.
A scientific theory is supported by a significant amount of evidence and has undergone extensive testing and validation by the scientific community.
Understand that scientific theories can be modified or refined as new evidence becomes available, but they are not unchangeable facts.
Conclude that the correct statement about a scientific theory is that it is a well-substantiated explanation of some aspect of the natural world, supported by evidence and subject to testing and refinement.
