Jack Skellington uses the Scientific Method to answer the question, "What is Christmas?" He borrows science lab equipment then follows the scientific process to figure out what is Christmas. He makes observations of the artifacts he collected from Christmas Land, asks the question, "What is this?", forms a testable hypothesis, makes a prediction, and tests the prediction. He never completes the last step, which is using the results to make new hypotheses or predictions, because of the havoc he caused while testing the prediction.
