What best defines a scientific theory?

• A. A simple idea
• B. A guess before experiments
• C. A measurement standard
• D. Greater body of accepted knowledge, principles, relationships that might explain a fact

Answer: (D)

A scientific theory is a well-supported framework that explains a wide range of phenomena by tying together many facts, observations, and relationships. It isn’t just a simple idea or a guess before experiments, and it isn’t a measurement standard. A theory is built from substantial evidence gathered through testing and observation, unifies diverse results, and makes testable predictions. It represents the best explanation scientists have given current evidence and can be refined or revised as new data emerge. The description that highlights a broad, accepted body of knowledge and relationships that explain phenomena best captures this idea, because it emphasizes the depth, coherence, and explanatory power of a theory.
