How is scientific inquiry best defined?

• A. The diverse ways in which scientists study the natural world and propose explanations based on evidence they gather.
• B. A fixed method for conducting experiments.
• C. A set of memorized facts about science.
• D. A process that ignores evidence to fit hypotheses.

Answer: (C)

Scientific inquiry is a flexible, evidence-based process that scientists use to study the natural world and develop explanations. It involves asking questions, making observations, forming hypotheses, designing tests or investigations, collecting and analyzing data, and drawing conclusions that are revised when new evidence emerges. Because there isn’t a single rigid method, inquiry encompasses a variety of approaches—from controlled experiments to careful observations and modeling—depending on the question and context. The emphasis is on building explanations that fit the evidence, not on memorizing facts or sticking to a preconceived idea. Options that describe a fixed method, memorized facts, or ignoring evidence don’t capture how science actually works. Varying methods and evidence-based reasoning are what make scientific inquiry robust and adaptable.
