To conduct a controlled experiment, you need to control all variables except the one you are changing. The variable you change is called the independent variable, and the variable you measure in response is the dependent variable. Control variables are those that could potentially affect the outcome of the experiment but are kept constant to isolate the effect of the independent variable.
A variable.
The independent variable is the one that is changed by the scientist.Control variables are kept unchanged in an experiment.Dependant variables are those that change as a result of the independent variable being changed.
that there is a relationship between the two variables. This relationship can be used to predict how changes in one variable will affect the other variable.
Variables that are intentionally manipulated or changed in an experiment are called independent variables. These changes are made to observe their effects on another variable called the dependent variable. By controlling and changing the independent variable, researchers can determine its impact on the dependent variable and draw conclusions about cause and effect relationships.
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.

Control Variable
The variable YOU change which will in turn effect another variable (the dependent variable). The controlled variable is plotted on the x - axis of a graph.
The three variable in an experiment are independent, dependent, and controlled. The independent is the variable you control, the dependent is the variable that will change according to the independent. The control is kept constant so they do not affect the dependent.
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.
Constants or control variables are kept constant during an experiment to isolate the effect of the independent variable on the dependent variable. These variables do not change in order to ensure that any observed changes in the dependent variable are due to the manipulation of the independent variable and not influenced by other factors.
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.
In an experiment, the variables that do not change are called constants or control variables. These are aspects of the experiment that are kept consistent and not altered, providing a baseline for comparison with the variable being tested. By controlling these factors, researchers can isolate the effects of the variable they are studying.
A scientist would need to identify variables so you could know what to change and what to keep the same. A scientist would need to control variables so you can try to see exactly which factors are affecting the dependent variable (the thing you're measuring). Hope this helped! Because I have the exact same question on my homework!
Control Variable
In a controlled experiment, the control variable is the one specific thing that is kept constant to measure the change of the other variables. Those variables are the parameters that are being tested.
