Kiera is preforming an experiment. She completed her first experimental trial and recorder the results. When she repeated the trial, she got a completely different result. What should Kiera do?

She should go through her experimental equipment, setup, and procedure with a fine-tooth comb, to find any little thing that she didn't consider during the first two runs.

Then, she should run the experiment again, one time, two times, or a hundred times more, until she's getting consistent, repeatable results.
