Honors Biology Class 7

The first thing we did in class was go over the homework. This included the different structures of carbohydrates like glucose, proteins and fats, like lipids. We also wen over how each component builds and breaks bonds through the process of hydration or dehydration.

After this we were given the choice between two different labs, my partner and I chose to do the one called Who Took Jerell's IPod. First we tested vegetable oil, Glucose, starch from potatoes, powdered egg whites, and water for Glucose, Starch, Proteins, and lipids. After this we tested pretzel, butter, jelly, fat-free yogurt, and beans for the same properties. Once this was finished we would choose two different types of evidence, one liquid and one solid, to test  and solve the mystery. Here are some pictures:

Testing for glucose using Benedict's and heat.

Testing for for starch and protein using iodine and biuret.

Here is what we used to test for each property. Once finished, we used the different properties we had collected and compared it with the results of the liquid and dry evidence of the thief. we found that the the thief would have to have glucose, starch and lipid, making the thief responsible for butter and pretzel. We had solved our case :).
