It's the variable in an experiment that is being modified or altered. For example, if I compare two sunflowers to see which will last the longest and put one in the shade instead of the sun, that sunflower is the experimental variable because I altered it.
The independent variable is the one variable that you change in your experiment
The independent variable is the variable that the researcher manipulates or controls in an experimental design in order to observe its effect on the dependent variable.
When non-experimental variables are held constant, it means keeping factors other than the independent variable the same for all participants or conditions in order to ensure that any observed effects are due to the independent variable and not to any other variable. This helps to isolate the impact of the independent variable on the dependent variable and strengthens the validity of the experiment.
Control variables are kept constant throughout an experiment to ensure that any changes in the dependent variable are due to the manipulation of the independent variable. Experimental variables, on the other hand, are the factors that are deliberately changed by the researcher to observe their effect on the dependent variable.
The variable setup in an experiment is called the experimental design. This design includes all the factors and conditions that are manipulated or controlled in the experiment to test the research hypothesis.
Variable
You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.

Independent variable
the experimental variable is like the independent variable, which is the only thing you can change in a science experiment, and the dependent variables are the things that stay the same.
the independent variable is changed, and the experimental value measure. So you control the independent variable and change it to measure the results
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
