Final answer:
The constant in an experiment recording daily water use could be elements like the number of people in a household or the method of measuring water, which remain the same throughout the experiment to ensure accurate results.
Step-by-step explanation:
In a science experiment that involves recording daily water use, a constant refers to a factor that is not changed throughout the course of the experiment.
In the context of such an experiment, the constant could be the number of people in the household, the time of day water usage is measured, or the method used to measure the water.
Ensuring that constants remain the same is crucial as it allows you to accurately assess the effect of the variable you are testing (for example, the impact of different water-saving strategies) on your daily water usage.
The compelte question is: In the experiment in which you recorded your daily water use, what was the constant? is:
