Which describes a series of steps followed to solve problems, including collecting data, forming a hypothesis, testing it, and stating conclusions?

• A. Force
• B. Mass
• C. Weight
• D. Scientific Method

Answer: (D)

The process used to solve problems in science is the scientific method. It describes a systematic, repeatable sequence for investigating questions: gather observations and data, propose a testable explanation (a hypothesis), design and perform experiments or measurements to test the hypothesis, analyze the results, and draw conclusions that explain what the data show. Stating conclusions and communicating findings are part of wrapping up the investigation and sharing what was learned. In the question, those steps—collecting data, forming a hypothesis, testing it, and stating conclusions—fit this approach, so the description best matches the scientific method. Force, mass, and weight describe quantities in physics rather than a step-by-step method. They are things studied or measured, not the process of solving problems.
