In his experiment, Sam controlled variables such as temperature, light exposure, and the amount of water provided to the plants. He ensured that each plant received the same type of soil and was planted at the same depth. Additionally, he standardized the duration of the experiment and the measurement intervals to maintain consistency across all test subjects. By controlling these variables, Sam aimed to isolate the effects of the independent variable on the plants' growth.
the dependant variable
The Variables That do not change in the experiment
the reason it is important to controll the variables in an experiment is because if the variables are not controlled in an experiment it will be impossible to reproduce the experiment. which also will make it impossible to prove the theory being tested
Control Variable
1337
Having a control in an experiment allows you to see what happens when no variables are changed. If you do not have a control, you do not have anything to compare your results with after changing variables of the experiment.
In an experiment, variables that are not changed are called control variables. These variables are kept constant to ensure that any changes observed in the experiment are due to the manipulated variable, or independent variable, and not due to other factors.
It is easier to control independent variables

The Variables That do not change in the experiment
It is so that the experiment is a fair test. In order to protect the integrity and / or accuracy of the experiment and its results, you have to be able to control all the variables so that you know exactly why something is happening. If you do not control the variables, then one of them could be the reason for the results, and you won't be sure why you got the results you did.

You need to control the variables because if you have two or more variables in an experiment you will never know which variable caused a change or not caused a change.
So that you can know what is the manipulating variable, the controlling variable, and the responding variable! To control the variables!
