Because otherwise you would not know what change caused the effect you noticed.
Thats what makes the variables what they are by definition they are what is changing
All variables except one, the experimental variable, are kept constant in an experiment.
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.
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.
The general term is 'controlled experiment'.
Meh... just wing it.
controlled experiment where all variables are kept constant except for the one being tested.

To ensure your experiment is fair, you must keep all variables constant except for the one you are testing. This means controlling outside factors that could influence the results of your experiment.

A constant is a part of the experiment that remains unchanged throughout the testing process. It provides a baseline for comparison with the variables being tested to determine their impact on the outcome of the 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.

Maintain a constant speed
they are like cheese they are smooth and stuff like that
