Which of the following is the correct sequence of steps in the five commonly taught steps of the scientific method?

• A. Ask a question, form a hypothesis, plan and conduct an experiment, collect and analyze data, and draw a conclusion.
• B. Form a hypothesis, ask a question, measure data, draw conclusions, plan an experiment.
• C. Start with a theory, test it, publish results.
• D. Observe, guess, test, repeat.

Answer: (A)

The main idea here is the organized sequence scientists use to test ideas. The best sequence starts with asking a question you want answered, then forming a testable hypothesis about it, followed by planning and conducting an experiment, then collecting and analyzing the data you gathered, and finally drawing a conclusion based on what the data show. This order matters because you need a clear question to guide a specific hypothesis, you need a plan to test that hypothesis, you need careful data from a controlled test, and you interpret that data to decide what happened and what it means. Other descriptions either scramble the order or skip essential steps—for example, guessing before you’ve asked a concrete question, skipping planning or data analysis, or jumping to publishing results without the experiment and analysis. A concrete example helps: if you wonder whether more sunlight makes a plant grow taller, you’d state a question, hypothesize that more sunlight leads to greater growth, plan an experiment with controlled variables to test that, collect height data over time, analyze the results, and then conclude whether sunlight actually affected growth.
