That depends on the experiment.
because other conditions could affect the dependent variable
A variable in an experiment that stays the same is a constant.
In a scientific experiment, a constant is a set value or substance that you would compare your results to. If you had four test tubes, the first would be a constant in which there are no variables, and each other test tube would have one variable. The constant shows the regular effects that would occur before a variable is added or adjusted in an experiment.
The controlled variable is the variable that is kept constant , meaning not changed, throughout the entire experiment.
A control in science is in an experiment that makes sure the science experiment only tests one variable. A constant is in an experiment and that is a variable that never changes.
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.

Constant variable
A constant variable is one that does not change during an experiment. If your experiment includes a dozen cupcakes and that number does not change throughout your experiment, the dozen cupcakes is a constant variable.
In an experiment, the variable that is held constant is called the control variable. This variable is not changed or manipulated during the experiment in order to isolate the effect of the independent variable on the dependent variable.

Control Variable
The definition of constant variable is a variable whose value cannot be changed once it has been assigned a value for an experiment. It is the variable held steady, or constant, for a specific experiment.
