The adjective "variable" just means "changeable."
In science, we call the factors in experiments "variables" (a noun). For example, if your experiment is to drop balls of different sizes and see how long it takes them to fall, the size of the ball is a variable, because you change it. The height from which you drop the ball is also a variable. Even if you drop them all from the same height, it's still a variable because you *could* have changed it.
In math, we call the undefined quantities in equations "variables" (also a noun). For example, in the equation y=2x, 'y' and 'x' are variables, because their values can change. The '2' is called a "constant", which just means "something that doesn't change."

Varible is something that you either keep the same or change in an experiment.

Do you mean variable? If so, it can mean a lot of things. It can be something inconsistant; someone whose inconsistant; capable of being diverse; of a star, changing in brightness; of a wind, changing in direction; a symbol of something that has no fixed value; or deviating from a strict type, as a species or specific character.
With a biological aspect, I think the last definition would be more helpful. Unless you're preforming experiments, then the second to last. there's dependent variable and independent variable. The dependent variable is called dependent because it varies depending what takes place during the experiment. The independent variable is the variable being manipulated, or changed.
