Write a brief paragraph (4–5 lines) describing how the scientific method contributes to progress in science, using the following example from the passage: "The scientific method comprises observation, hypothesis, experimentation, analysis, and conclusion. For instance, when the scientist observed that light bent around a stone, he hypothesised a change in direction and performed experiments to confirm this."
Answer
The scientific method allows systematic inquiry: starting with observation of light bending around a stone, the scientist formed a hypothesis that light changes direction. Through controlled experiments, he confirmed this, analysed the data, and drew a conclusion, thus advancing knowledge of optics. By repeating this cycle, science builds reliable, cumulative knowledge.
Step-by-step solution
- Identify the stages of the scientific method mentioned: observation, hypothesis, experimentation, analysis, conclusion.
- Relate each stage to the example: observe light bending, hypothesize direction change, experiment to confirm, analyse results, conclude about optics.
- Explain how these steps systematically build reliable knowledge.
- Write the paragraph in 4–5 lines, keeping each stage clear.
