How might a scientist compare theories by doing an experiment?

A.
Make sure that the experiment is properly controlled.


B.
Do an experiment which could only apply to one of the theories.


C.
Check if the experiment gives the same results when it is repeated.


D.
See which theory does a better job of explaining the results of the experiment.

Respuesta :

I think the answer is C, because repeating an experiment would mean the result is more accurate when done more then once. i learned this in around 7th grade, I hope it helps! (:

Answer:

The correct answer is option D. "See which theory does a better job of explaining the results of the experiment".

Explanation:

A theory is a well established supposition that explains a phenomenon observed in nature or in laboratory based on proved principles. A scientist could compare theories by doing an experiment to see which theory does a better job of explaining the results of the experiment. This helps to see which theory is accurate and getting closer to get a definitive explanation to the observed phenomenon.
