it is easier to manipulate when you have several controls and only one variable
The three scientific variables are independent variables, dependent variables, and controlled variables. The independent variable is the variable that is manipulated or changed by the researcher. The dependent variable is the variable that is measured or observed in response to the changes in the independent variable. Controlled variables are the factors that are kept constant to ensure that they do not influence the relationship between the independent and dependent variables.
The independent variable is also called an experimental variable. It is the variable being manipulated in the experiment in order to show the effect on the dependent variable. The dependent variable is also called the response variable. It is the variable being observed in the experiment. A change in the independent variable is what causes the change (if any) in the dependent variable, which is the purpose of the experiment.
The purpose of a control variable in an experiment is to allow the experiment to come out with accurate results. It makes it a lot easier to measure the results when different things aren't affecting it.

A controlled experiment is a scientific study in which one variable is manipulated (independent variable) while all others are held constant, to observe the effects on another variable (dependent variable). The purpose is to determine causation between the variables being studied.
A controlled variable is a factor or condition that is intentionally kept constant and unchanged throughout an experiment. Its purpose is to ensure that any observed effects or changes are due to the manipulated variables and not influenced by other factors.
A manipulated variable, also known as an independent variable, is the variable that is intentionally changed or controlled by the experimenter in an experiment. Its purpose is to determine the effect it has on the dependent variable.
The independent variable is the condition that changes in an experiment while all the other variables remain constant. The purpose of changing this variable is to observe its effect on the dependent variable.

An independent variable or manipulated variable is when you change it on purpose. For example, say your scientific problem was "Does certain substances affect how fast water is frozen?" Those substances are the indepentant variables. A dependant variable is how you measure the dependant variable. For instance, the dependant variable would be how fast the water is frozen. The things they have in common are that they are both variables and are subject to change.
The factor in an experiment that is changed on purpose is called the independent variable. This variable is manipulated by the researcher to observe its effect on the dependent variable. It is the cause being studied in the experiment.
A control variable is a condition that remains constant or unchanged in an experiment. Its purpose is to serve as a baseline for comparison to see the effects of manipulating other variables.

No, the independent variable and the control variable cannot be the same. The independent variable is what is being changed or manipulated in an experiment to observe its effect on the dependent variable, while the control variable is kept constant to minimize its impact on the results. Having them be the same would defeat the purpose of having a control variable.
