What is the scientific method and how it is used in investigations?
Steps of a scientific investigation include identifying a research question or problem, forming a hypothesis, gathering evidence, analyzing evidence, deciding whether the evidence supports the hypothesis, drawing conclusions, and communicating the results. Scientific research must be guided by ethical rules.
Why is the scientific method important?
