Question

Which of the following is an example of a scientific question that could be used to create an easily reproducible experiment? a. Why do people like to watch television? b. Does the mass of a rocket affect the distance it can travel? c. What makes the sky blue? d. Does sugar or salt have a greater effect on plant growth?

Answer 1

I think that the key point here is the "easily reproducible" - because all of them can be scientific questions (even a! it could tell us about about the human psyche!)

but d. is the best answer for a reproducible experiment. B could also make a good experiment, but it would be too expensive to be easily reproducible. C is calling for a more complex analysis that is too complex for an experiment. And a would require more questionnaires than experiments
