Final answer:
A scientific law is a concise and generalized statement that describes a pattern in nature, while a scientific theory is a more complex explanation of observed phenomena.
Step-by-step explanation:
A scientific law is a concise and generalized statement that describes a pattern in nature, supported by scientific evidence and repeated experiments. It is often expressed in the form of a single sentence or mathematical equation. On the other hand, a scientific theory is a more complex and dynamic explanation of observed phenomena, which cannot be expressed concisely enough to be considered a law. The theory explains an entire group of related phenomena and evolves with time to incorporate new facts.
