Which best describes the Scientific Method?

• A. A guess and confirmation by trial and error
• B. A series of steps including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions
• C. A single experiment to prove a theory
• D. A process limited to physics and chemistry

Answer: (B)

The scientific method is a systematic process scientists use to investigate questions and build explanations from evidence. It centers on gathering data, forming a testable hypothesis, testing that hypothesis through experiments or observations, and drawing conclusions from the results. This aligns with the best description because it emphasizes a clear sequence driven by evidence rather than guesswork, and it goes beyond a single experiment to support ideas over time. It also applies across many fields, not just physics and chemistry. For example, noticing that seeds germinate faster at warmer temperatures leads to a hypothesis about temperature affecting germination, which is then tested with controlled experiments, data collected, and conclusions drawn from what the data show.
