An experiment is based on controlling the environment, reactants, and conditions under which the procedures are carried out. If other externalities (variables) are not accounted for the experiment will be subject to sources of error. If a single variable is held constant than the test will be more accurate and replicable.
Changing only one variable at a time allows you to distinguish the particular effects of that variable. If you change more than one variable then you cannot tell which change made what difference.
independent variable can be controlled by manipulation or selection.
The independent variable in an controlled experiment is what you are changing

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
independent variable can be controlled by manipulation or selection.
In a controlled experiment, the Independent variable refers to the variable that is manipulated or altered. The dependent variable, meanwhile, is the result of the experiment.

the things you change
No, it could be one, but that does not necessarily classify it as controlled. A controlled experiment is an experiment that has only ONE independent variable, and other variables are kept the same.
The Variable is the one factor that differs in a controlled experiment.

Variables that do not change in an experiment are independent variables.
Variables that do not change in an experiment are independent variables.
An experiment with only one independent variable (manipulated part). All of the other variables are kept constant throughout the trials of the experiment.
