In an experiment you are usually comparing the variable against the constant. The constant is the normal state of what is being measured or observed. The variable is the unknown aspect of the experiment that is being measured or observed to determine a difference from the constant.

example, you wanna test whether a plant grows well in darkness or in sunlight. So you have 2 same plants of same age and size, the only difference you make is that one you put in under the sun and the other inside a cupboard.
so the variable of this experiment is the amount of light given to the plant.
hope this helps

A variable is anything that is not constant. The less variables, the better the expirement.
