Final answer:
When the results of an experiment do not support a theory, scientists conduct further experiments to gather more data and refine their understanding.
Step-by-step explanation:
When the results of an experiment do not support a theory, scientists conduct further experiments. They may modify their hypothesis and design new experiments to gather more data and draw more accurate conclusions. This iterative process allows scientists to refine their understanding of the phenomenon they are studying and develop new theories or modify existing ones based on empirical evidence.
