In order for the results to be valid, the dependent variable can only be affected by the independent variable, so somethings need to be kept CONSTANT. The things that need to be kept constant are called CONTROLLED VARIABLES. Even if controlled variables are affecting the dependent variable(s), which they usually do, keeping them constant will ensure that all trials of an investigation were equally impacted by the controlled variables, therefore allowing one to see the impact of an independent variable on the dependent variable.
All in all, a 'constant' in a science experiment should actually be called a 'controlled variable' and the description of such a variable is described in the third point. Hope this clarifies.

What is the difference between a constant in a graph and a constant in a experiment?
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
Examples of constant variable?
A constant variable is one that does not change during an experiment. If your experiment includes a dozen cupcakes and that number does not change throughout your experiment, the dozen cupcakes is a constant variable.
What a variable that does not change in an experiment is called a constant?
Constant variable
What stays the same in an experiment?
the constant
What is the dependent variable to the coloring changing carnations experiment?
The dependent variable in the color changing carnations experiment is the carnation in the plain water.
