Read each question carefully and provide your best answer. This worksheet assesses your understanding of scientific hypotheses, theories, and laws.
1. Which of the following best describes a scientific hypothesis?
A well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.
A statement that describes an observable phenomenon in nature without explaining why it occurs.

1. A scientific is a concise statement that summarizes an observed phenomenon in nature, often expressed mathematically.
2. Before a hypothesis can become a theory, it must undergo extensive and be supported by a significant amount of empirical evidence.
3. The primary difference between a scientific theory and a scientific law is that a theory offers an , while a law provides a .
1. Explain the relationship between a hypothesis, a theory, and a law in the context of the scientific method. How do they build upon each other?
2. Provide an example of a scientific law and explain why it is classified as a law rather than a theory.
