Controlled Variable
The control of an experiment is the part of an experiment that does not change, and is strictly used as a comparison to the variable that is being tested.
The part where experiment is spelled wrong. :P It's also the independent variable:)
The part that is held for comparison is called "the control". It can also be called the "independent variable" depending on what your teacher uses.
