There are 2 variables and they are independent and dependant.
It is important to have controlled variables in a scientific experiment because it is the variable that remains the same it doesn't change. Its a consent & can be measured against.
a scientific method to tell what stayed the same in an experiment
In a scientific method (or experiment), a dependent variable is one that changes throughout the experiment. These are the ones whose changes need to be recorded. Independent variables are those that influence the experiment, but do not change throughout the experiment and remain the same value.

In scientific experiments, the variables may be changed.

It is easier to control independent variables

Independent and dependent does go under experiment on the scientific method.

A scientific experiment must be done by something that can show change. All of these can be variables.
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
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.
