Explanation:
When a scientist describes the materials that she used and how she performed her experiments, it tells the audience if the results supports or contradicts the hypothesis.
A hypothesis formulation helps to test a scientific claims.
Experiments are usually hinged on well designed hypothesis.
From the hypothesis, one can be sure the experiment is tuned and designed within the scope of the observation desired to be tested.
This is why the materials used and procedures followed in an experiment can tell if the results supports or contradicts the hypothesis.
