Independent and Dependent Variables
A constant
continuous
It's called a controlled experiment.

Environmental factors if you cannot control them.Variable factors if you can control them.See link below for easy explanation:In an experiment the scientist is able to change the independent variable. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. - See more at: http://www.chacha.com/question/what-part-of-an-experiment-is-the-factor-that-you-change#sthash.iyH25Jac.dpufIn an experiment the scientist is able to change the independent variable.

The answer you predict before starting the experiment is your hypothesis.
It's called a controlled experiment.
A constant factor is one maintained unchanged throughout an experiment so that it does not affect the outcome. These are also referred to as controlled variables.
An experiment in which all variables stay the same is called a "controlled experiment".
Variables.
Constants are factors in an experiment that stay the same. This should not be confused with controls -- which is a standard used for comparison
The factors which you change (vary) are called variables.

These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
things in an experiment that stay the same are called constants.
