A variable.
variables
An experiment is almost always designed so that two (and no more) things will change.-- You, the experimenter, will change one of them as you desire.-- That will cause a change in the other one, which you will carefully measure.
A variable that doesn't change in an experiment is called a constant. Constants are used to ensure that only one variable is being tested for its effect on the outcome of the experiment.
The variable that does not change in an experiment is called the control variable. It is used as a benchmark for comparison to observe the effects of the other variables being tested.

You only change 1 iv ( independent variable in a experiment ) HOPE IT HELPS :)
A factor in a scientific experiment that is subject to change is called a variable.
The variable that is intentionally changed in an experiment is called the independent variable.
The factors which you change (vary) are called variables.
Variables
The part of an experiment that you test or manipulate change is called your independent variable.
they are the things that don't change in an experiment/ that don't receive any special treatment.
A variable that doesn't change in an experiment is called a constant. Constants are used to ensure that only one variable is being tested for its effect on the outcome of the experiment.
In an experiment, factors that you change are called independent variables.
things in an experiment that stay the same are called constants.
