The dependent variable is the variable that the researcher does not control. The researcher will change one variable called the independent variable (ex. temperature, amount of sunlight, amount of food, etc.) and then observe the corresponding dependent variable (ex. reaction of organism, amount of plant growth, swimming speed, etc.)

Any variable can be the independent variable. It depends partly on what the dependent variable is, partly on the relationship you are examining. For example, if looking at age and length of children's feet, foot length would be considered the dependent variable. But if looking at foot length and shoe size, then foot length would be the independent variable.
