Because it's an experiment not a replication...
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
The dependent variable is the variable that can change in an experiment.
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.
What is a variable in a experiment
variable is a factor in an experiment that can change
an independent variable is a figure usually shown as a letter that is used in the scientific theory. An independent variable is used in a hypothesized experiment in which this variable is unchanged and is used to effect the dependent variable somewhere in the experiment.

The independent variable is the variable that is changed during an experiment.

You could say, "Today in our science experiment we had to figure out what the dependent variable was"
The independent variable of an experiment is the variable that you change, and the dependent variable is the result of the independent variable.
