Final answer:
An example of a scientific question is: "Do different types of soil affect plant growth?" This involves forming a hypothesis, such as plants growing taller in loamy soil versus sandy soil, and then conducting an experiment to test and measure the results. Not all questions, like those based on personal preference, can be tested scientifically.
Step-by-step explanation:
Example of a Question for Scientific Investigation
One example of a question that can be tested through scientific investigation is: "Do different types of soil affect plant growth?" This question begins with an observation — perhaps a gardener notices some plants grow well in one type of soil but not in another. Next, a hypothesis might be proposed, such as "Plants grow taller in loamy soil compared to sandy soil." This hypothesis is testable because it is specific and measurable.
To conduct the investigation, an experiment could involve growing identical plants in both types of soil under controlled conditions and measuring their growth over time. If, after the experiment, the plants in loamy soil are consistently taller than those in sandy soil, the hypothesis would be supported. If not, the hypothesis may be rejected, or further investigation might be warranted.
However, not all questions can undergo scientific testing. For example, the question "Which genre of music is the best?" is subjective and cannot be answered through scientific methods. Opinions and personal preferences are not measurable or observable in the same way as physical phenomena.
