Variables.
The variable is the part that is changed in the experiment; the constants are the parts that stay the same.
In a scientific method (or experiment), a dependent variable is one that changes throughout the experiment. These are the ones whose changes need to be recorded. Independent variables are those that influence the experiment, but do not change throughout the experiment and remain the same value.
In science constants are the things which never change. The speed of light is a constant, so is the mass of an electron. Variables are quantities which can change. The temperature of the oceans, the economy of the country for example.
Constants are the factors which do not change. Variables are the factors which change. If that is what you are referring to.
Variables change, constants do not.
Empirical constants are used whenever something can not be rationalized in science. Essentially, these constants act as fudge factors, or scientific variables used without basis in a model.

Independent and dependent does go under experiment on the scientific method.

Constants are fixed numbers that never change, they always stay the same. Variables are number that can change, they 'Vary'.
The ones called constants.
