What is the second step of the scientific method?

• A. Formulating a theory
• B. Generating a hypothesis
• C. Collecting data
• D. Making an observation

Answer: (B)

The second step is generating a hypothesis. After you’ve made initial observations and formed a question, you shape a clear, testable statement about how you think the world works. This guess isn’t random; it’s a specific claim that makes predictions you can test with experiments or measurements. The hypothesis provides direction for the study—what to change (the independent variable), what you’ll measure (the dependent variable), and what results would support or refute the idea. For example, if you notice that seeds appear to germinate faster in warmth, your hypothesis might be that higher temperatures speed germination. You’d then design an experiment to test seeds at different temperatures and collect data on germination time. Data collection and analysis come after you’ve stated the hypothesis and planned the test. Forming a theory, by contrast, is what scientists develop after many reliable hypotheses have been tested and repeatedly supported. Making an observation is the starting point, not the second step, because it’s the raw information that leads to the question and the subsequent hypothesis.
