Verified step by step guidance

1. Understand that the scientific method is a systematic approach used to investigate phenomena, acquire new knowledge, or correct and integrate previous knowledge.
2. Recognize that the first step in the scientific method is to make an observation about a phenomenon, which involves noticing and describing something interesting or unexplained.
3. After making an observation, the next step is usually to formulate a hypothesis, which is a testable explanation for the observed phenomenon.
4. Following the hypothesis, scientists conduct experiments to test whether the hypothesis is supported or refuted by data.
5. Finally, analyzing data from the experiments helps to draw conclusions and refine the understanding of the phenomenon.
