I did a lab and have been graded already. One of the questions asked us to pick good scientific questions from a list of choices.

Question

One of the choices read, "What soil properties determine the resulting color of a plant's flowers?". Note: I have changed the wording slightly.

I did not include that as a good scientific question because it is to vague or broad. There are lots of properties that can affect a plant's flower color such as moisture/lack of, pH, soil type, soil compaction, and more. This would lead to a yes possible, but complex experiment. I think if the question had been more specific as to which property of soil needed to be tested, then it would have been a viable option.

Do you think this is a good scientific question? Why or why not?
