  Basically, it means that ANYTHING that can change in an experiment is a variable. We'll use plants as an example. The variables are: plant growth, sunlight, temperature, water, soil type, plant type, whether or not you play music to the plant, etc.
Now some of those variables will be controlled and kept the same to ensure that you are only testing one variable (if you're testing if playing music to plants makes them grow then you will control the sunlight, water, soil type, plant type, etc. to make sure that nothing else can effect the plant). The variable you are intentionally changing is of course the independent variable (in this case the music) and what you are hypothesizing will change because of the difference in the independent variable is your dependent variable (the plant growth.)
