Read each question carefully and provide thoughtful answers based on your understanding of scientific principles. This worksheet will assess your knowledge 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, often expressed mathematically, but does not explain why it occurs.
A testable explanation for a specific phenomenon, based on prior knowledge or observations, that can be supported or refuted through experimentation.
A universal truth that has been proven beyond any doubt.
2. The Law of Conservation of Mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. This statement is an example of a scientific:
Hypothesis
Theory
Law
Conjecture
3. A scientific is a testable explanation that addresses a specific question or problem.
4. The Big Bang is a widely accepted explanation for the origin and evolution of the universe, supported by a vast amount of evidence.
5. A scientific describes an observed phenomenon in nature without necessarily explaining why or how it occurs.
6. A scientific theory can eventually become a scientific law if enough evidence is gathered to support it.
True
False
7. A hypothesis is always proven correct after a single experiment.
True
False
8. Differentiate between a scientific theory and a scientific law. Provide an example for each.
9. Explain the role of a hypothesis in the scientific method. What makes a good hypothesis?
Match each statement with the correct scientific term.
10. An explanation for a broad range of phenomena that is supported by extensive evidence.
a. Hypothesis
11. A testable prediction or educated guess.
b. Theory
12. A description of an observed relationship in nature, often mathematical.
c. Law
