Class 09/12

Today in class we had the option to choose between two different labs. My group chose to do the lab about finding out who stole Jerrel's iPod. This lab helped us to understand macromolecules and the scientific method. We tested samples of a bean burrito with cheese, fat-free yogurt, toast with butter and jelly, pretzel, and a sample of the substance left on the desk where the iPod was for glucose, starch, protein, and lipids. We tested to see which of the lunch food snacks matched the substance left on the iPod. We know that whichever substance was made of the same molecules would lead to the person who took the iPod.
