The experimental variable (also know as the intendant variable) is the part of an experiment we change each time we repeat the test.
For example, if you were measuring the time it takes for a substance to react in different acids, the variable we would change would be the type of acid.
The control variable is a part of the experiment which basically gives you a value to compare your other results to.
Using the same example, you may do a test to see how long it takes for the substance to react in water. You could then compare this to the rest of your results for the reactions with the acids.
The example may not be the best, but it gives you the right idea...
Also the dependant variable is...like the name suggests...dependant on the independent variable.
The dependant variable in my example would be the time it takes for the substance to completely react with each acid
independent variables are the variable in the experiment that are not changed; the dependent variable is dependent on the change, they are the variable that are experimented on. The experimental group is the one that is being tested on. the control group is used as a basis for what changes are taking place
Independent variable
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
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.

Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
A control group is the standard of comparison between what happens with the experimental variable and without the experimental variable.

control setup
experimental control
The experimental control is what you compare your experimental data with. Without the control, you can't tell if the variable you are testing is what is causing your results.
control group
the independent variable is changed, and the experimental value measure. So you control the independent variable and change it to measure the results
