EXPERIMENTAL DESIGN (10 points)   Jack only ever eats lettuce in his salads because he doesn’t like vegetables.   (He’s not too fond of lettuce either…)  But for Earth Day a few weeks ago, Jack’s aunt made everyone eat salads at the family dinner and added ingredients Jack had never eaten:  baby carrots, grape tomatoes, parmesan cheese, and bacon bits.  The next morning Jack woke up and was short of breath like he had never been before.   Using the scientific method, determine which one of the salad ingredients caused Jack’s shortness of breath.   Hypothesis (1):   Describe your procedure (2):   Prediction: (1)   For your experiment, what is/are the   Standardized variables: (2)   Independent variable: (1)   Dependent variable: (1)   Control group: (1)   Experimental group: (1)
