Scientific Method  Scientists have long suspected that high-fructose corn syrup, used to sweeten soda, is one of the causes of childhood obesity. In a recent study, researchers found that mice that drank water with added fructose ate less solid food, gained more weight and put on 90% more body fat than mice that drank only water. Scientists concluded that fructose may affect metabolism in a way that favors fat storage.  The independent variable in this experiment is ___________.
