Which of the following correctly lists the typical steps of the scientific method in order?

• A. Ask a question, form a hypothesis, plan/perform an experiment, collect and observe data, analyze results, draw a conclusion, and communicate the findings.
• B. Form a hypothesis, ask a question, perform an experiment, analyze results, communicate findings, draw a conclusion.
• C. Observe data, ask question, test, conclude.
• D. Communicate findings before experimentation.

Answer: (A)

The main idea being tested is the logical sequence of investigating something in science. You begin with a question that comes from curiosity or careful observation, then propose a testable hypothesis—a educated guess about what might be happening. Next, you plan and carry out an experiment to test that hypothesis, making sure to control variables so you can see the real effect of what you’re testing. While doing this, you collect and record data from your observations and measurements. After gathering data, you analyze it to look for patterns, compare with what you expected, and decide whether the results support or refute your hypothesis. Finally, you draw a conclusion that sums up what was learned, notes any limitations or sources of error, and you communicate your findings so others can understand and potentially replicate the work.

This order is best because it moves from asking a question to testing it with data, and ends with sharing the results. Other sequences either skip steps, place data analysis or conclusion in the wrong place, or put communicating findings before you’ve gathered and analyzed results, which doesn’t fit how scientific investigations are typically conducted.
