Answer :
Final answer:
Jackson's best choice for a scientific question in his project is option B, which investigates how gravity affects potato plant growth. This question is testable and relevant to his study of plant biology. The other options do not pertain to scientific experimentation or plant growth directly.
Explanation:
Identifying a Scientific Question for Plant Growth
In Jackson's science fair project on plant growth, it's crucial to choose a question that is scientific and testable. Among the options provided, option B: "How does a potato plant's growth change when the direction of gravity changes?" serves as a reasonable scientific question. This question aligns with the scientific method as it is specific, can be tested through experiments, and relates directly to plant growth and environmental factors.
The other options, while interesting, do not fit the criteria for a scientific inquiry:
- A. Questions about profits are related to economics, not biological processes.
- C. Questions about ingredients for a potato salad focus on culinary aspects rather than scientific investigation.
- D. Interest in gardening concerns human behavior and subjective opinions, not measurable scientific phenomena.
Therefore, Jackson should focus on option B for an effective science fair project that explores the influence of gravity on potato plant growth.
