Scientific Method

Observation
- Identifying phenomena and gathering data.
Question
- Formulating questions based on observations.
Hypothesis
- Proposing a testable explanation for the observations.
Experimentation
- Conducting experiments to test the hypothesis.
Analysis
- Analyzing data collected from experiments.
Conclusion
- Drawing conclusions based on data analysis, either supporting or refuting the hypothesis.
