Mad Scientists in Soda Lab Hysteria!
So this is the result of an experiment we did in science class for a test of the scientific method. The students had to create an experiment in which they tested a hypothesis about five different sodas. They had to drink five different sodas, then rate them all on a scale of 1-10 on five different variables. We calculated the average rating they gave each soda, then plotted it on a graph. They had to measure the variables against each other, one as independent and one as dependent, for instance "I believe that the fruitier a soda is, the more thirst-quenching it will be" is an example of a hypothesis in which fruitiness is the independent variable and thirst-quenching ability is the dependent variable. Then they had to create their own charts that tested their two variables to see if they had a positive or a negative correlation, or any correlation at all. I used some rather strange sodas, and included seltzer as well. The president of one of the major grocery chains here in New York (Gristede's, Key Food, D'Agostino, C-Town, one of those) just released a statement that the number one best-selling product in New York City supermarkets is a one-liter bottle of seltzer. That is what is purchased more often than any other grocery item. Does that seem strange to you? Especially because my students all hated it, hated it only a little bit less than the ginger beer.
