What are the factors in an experiment that must be kept the same called?

In an experiment, the factors that must be kept the same throughout the entire process are known as constants. These constants are essential because they help to ensure that the experiment is fair and that any changes in the results can be attributed to the independent variable being tested, rather than other factors. By controlling these variables, researchers can isolate the effects of the independent variable, leading to more reliable and valid conclusions.

When all constants are maintained, it allows for a clearer understanding of the relationship between the independent and dependent variables. If these constants were to change, it could introduce confounding variables, which could skew the results or lead to false conclusions about the experiment's outcomes.

In contrast, variables are the elements that can change, while controls are the standard for comparison in an experiment, and hypotheses are testable predictions about the outcome of an experiment. Keeping constants in mind helps reinforce the integrity of the experimental design and ensures the validity of the findings.
