What variables must be kept constant
Constant variable
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.
Such a number is called a "constant". If the number appears in front of a variable, it is sometimes called a "coefficient".
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
What variables must be kept constant
Constant variable
The independent variable. Any variable that is kept the same is a constant variable (although it is a contradiction in terms); any variable - usually only one - that depends on the independent variable is a dependent variable.
The constant variable is usually the 'X' variable or the variable that stays the same. For example, it may be the 'X' variable or the same number.

All variables except one, the experimental variable, are kept constant in an experiment.

That is simply called a constant.
The controlled variable is the variable that is kept constant , meaning not changed, throughout the entire experiment.
factors in an experiment that are kept the same and not allowed to change or vary.
