Select the correct answer.
Neville is testing a hypothesis through experimentation. He believes that raising the temperature difference between two water samples will lead to
stronger circular currents when the samples are mixed together. Which of
these actions would be considered a mistake in Neville's experiment?
A.
He measures the strength of each current using the same flow meter.
O B.
○ C.
O D.
O E.
He states his hypothesis prior to beginning any of his experimental trials.
He randomly varies the volume of hot and cold water across his trials.
He reruns the experiment after fixing calibration problems with his thermometers.
He uses glass containers to hold the water samples instead of plastic ones.

In Neville's experiment where he is testing the hypothesis that raising the temperature difference between two water samples will lead to stronger circular currents when the samples are mixed together, the action considered a mistake in his experiment is: - He measures the strength of each current using the same flow meter. Using the same flow meter for measuring the strength of each current in different samples may introduce bias or error into the results. It is essential in experiments to maintain consistency and control over variables to ensure that any observed effects are due to the manipulated factor (temperature difference in this case) and not influenced by other factors like measurement tools. By using different flow meters for each sample, Neville could have better ensured that any differences in the strength of the currents observed were indeed due to the temperature difference and not a result of measurement inconsistencies.
