What are the 7 steps of the Scientific Method commonly used by scientists? Outline how you would take each of these steps in a hypothetical research project.
The correct answer and explanation is :
The 7 Steps of the Scientific Method are:
- Observation
- Question
- Hypothesis
- Experiment
- Data Collection
- Analysis & Conclusion
- Communication of Results
Hypothetical Research Project Example
Topic: Effect of Different Fertilizers on Plant Growth
- Observation: You notice that some plants in your garden grow faster and healthier than others, even though they receive the same amount of sunlight and water.
- Question: Does the type of fertilizer affect the growth rate of plants?
- Hypothesis: If plants are given organic fertilizer, they will grow taller and healthier than plants given chemical fertilizer or no fertilizer.
- Experiment:
- Select three groups of identical plants.
- Group A receives organic fertilizer, Group B receives chemical fertilizer, and Group C receives no fertilizer.
- Control variables: same soil type, water, and sunlight exposure.
- Measure plant height every week for 6 weeks.
- Data Collection:
- Record the height, leaf color, and overall health of plants in a table.
- Take photos for comparison.
- Analysis & Conclusion:
- Analyze the data to see which group had the best growth.
- If Group A (organic fertilizer) had the best growth, the hypothesis is supported.
- If another group grew better, revise the hypothesis and investigate further.
- Communication of Results:
- Publish findings in a scientific journal or present them at a conference.
- Share results with farmers and gardeners for practical use.
