Since many students wondered what was happening to the trout's food sources, we agreed to examine food in the first place. Looking at various food labels, students agreed on the following: that all foods contain some kind of protein, fat, or carbohydrate to give us energy and help us grow and repair our bodies. Since trout are living organisms, too, they must also need various combinations of these substances. We also figured out that there must be a way to test what substances are in our foods, so next week we'll be doing a bunch of chemical tests to figure out just that!
