Jumping for Geodes Project by ScienceBuddies

One of the requirements for a science fair project at our school is, "Identify the one VARIABLE and several CONTROLS for your experiment." In this project, the student observes the outside texture and color of several geodes and tries to determine if it is possible to predict the size and color of the crystals inside. What would the one VARIABLE and several CONTROLS be in this case?
