Answer
The independent variable is the one you are changing.  The dependent variable is the one that reacts to the thing you are changing.  You measure the dependent variable.

Example:  The experiment wants to know if being sleepy makes you do poorly on a test.  The independent variable (the cause - one you are changing) is how many hours of sleep you get.  The dependent variable (the effect - the result you are measuring) is the score you get on the test.
