The scientific method is a systematic process that scientists use to investigate natural phenomena, solve problems, and test ideas. It helps ensure that knowledge is reliable, logical, and based on evidence.
Main Steps of the Scientific Method:
- Observation
- Carefully noticing and describing something in the natural world.
- Example: A plant grows better in sunlight than in shade.
- Question/Problem
- Formulating a clear, specific question to investigate.
- Example: Does sunlight affect plant growth?
- Hypothesis
- Proposing an educated guess or possible explanation that can be tested.
- Example: If a plant gets more sunlight, then it will grow taller.
- Experiment
- Designing and performing controlled experiments to test the hypothesis.
- Example: Grow one plant in sunlight and another in shade under the same conditions.
- Data Collection and Analysis
- Recording results and analyzing them to see patterns or differences.
- Conclusion
- Stating whether the data supports or rejects the hypothesis.
- Example: The plant in sunlight grew taller, supporting the hypothesis.
- Communication
- Sharing findings with others through reports, papers, or discussions.
- Repetition
- Repeating experiments to verify accuracy and reliability.
