What isdependent variable?

The dependent variable in an experiment is the thing that changes due to the experimentor changing the independent variable. Basically, its what you measure and record. For example: you create an experiment that observes the effects of the amount of sunlight on plants. You give one plant more sunlight than the other, leaving everything else exactly the same. That is your independent variable. Say you measure the height of each plant every week. Since the height is DEPENDENT on the amount of sunlight each plant got, the height is your dependent variable.
