What is the typical progression in scientific investigations?

• A. Hypothesis → Observations → Question → Test → Report.
• B. Observations → Question → Hypothesis → Test → Conclusion → Report results.
• C. Observations → Test → Question → Hypothesis.
• D. Conclusion → Observations → Question.

Answer: (B)

In scientific investigations, the flow starts with gathering observations that reveal patterns or phenomena, which then lead to a question about why those patterns occur. From that question, you state a hypothesis—a specific, testable explanation or prediction. The next step is to design and perform tests or experiments to see if the results align with the hypothesis. After collecting and analyzing the data from those tests, you draw a conclusion about whether the evidence supports or refutes the hypothesis. Finally, you report the results, including methods, data, and interpretations, so others can evaluate and replicate the work. This sequence—observations, question, hypothesis, test, conclusion, and reporting—puts each step on a logical, testable path and keeps the investigation communicable.
