Final answer:
Maintaining constants in an experiment ensures consistency and reliable results by controlling external factors.
Explanation:
Maintaining constants within an experiment is crucial to ensure consistency in all trials. By keeping variables constant except the one being tested (independent variable), researchers can control for external factors that could influence the results, hence achieving more reliable and interpretable outcomes.
For example, when studying the effect of temperature on plant growth, maintaining constant soil moisture and light exposure allows researchers to attribute any differences observed solely to temperature variations.
