Thats what makes the variables what they are by definition they are what is changing
Everything should be held constant except for one independent variable, the one thing you change. If you don't keep everything else constant, you can't determine the cause of changes in the dependent variable.
All variables except one, the experimental variable, are kept constant in an experiment.
In order to isolate and identify the effect of the variable being tested, it is important to keep all other factors constant. This allows for a more accurate and reliable assessment of the relationship between the variable and the outcome. If other factors were to vary, it would be difficult to determine whether any observed changes were due to the variable being tested or to external factors.
Because otherwise you would not know what change caused the effect you noticed.
Keeping all the relevant conditions in an experiment the same except manipulated variable is called

All variables except one, the experimental variable, are kept constant in an experiment.
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.

Meh... just wing it.

It means that except for the independent variable (the only factor that you change) you remain the other variables constant. To keep the control variables the same. Then this is a controlled experiment (fair test). Hope this helps :)
A constant.
