The answer to your question is the Control Group.
A constant in an experiment is something that does not change, such as the temperature, pressure, or a control variable that is kept the same throughout the experiment to ensure accurate results.
Yes, the independent variable does change because it is what a scientist purposely changes during an experiment.
Variables.
A variable represents things that are involved in an experiment. The control is the variable that doesn't change regardless of the experiment.
A control variable is a factor that remains constant and does not change during an experiment. It is used to ensure that any observed effects or changes are due to the manipulation of the independent variable and not other factors.
Variable
A constant in an experiment is something that does not change, such as the temperature, pressure, or a control variable that is kept the same throughout the experiment to ensure accurate results.
The chemical composition and physical state of substances can change during an experiment.For example two reactants in solid or liquid form can react in an experiment to give a product in a gaseous form.

Constant
Something you would either keep the same or change during a practical, to ensure the experiment is a fair test.
A variable.
A variable is something that may be changed or manipulated during a experiment.
There are different types of factors that can change in an experiment. The environmental factors may change, and are out of your control. The variables in the experiment may also be changed but, are usually controlled by the individual conducting the experiment the majority of the time.
The Independent variable
A control is the standard to which an outcome of an experiment is compared, but a variable is something in an experiment that can change.
A scientific experiment must be done by something that can show change. All of these can be variables.
