Class 7

   In class today we learned about lipids (proteins and fats) and carbohydrates (glucose). we also learned about condensation, hydration and dehydration. We had a choice between two different labs covering similar topics. My partner and I chose "Who took Jarell's iPod" lab. In this lab we had to test different food items to see who took Jarells Ipod. We first tested vegetable oil, starch and glucose from potatoes, powdered egg whites and water for starch, lipids, proteins and glucose. We then did similar testing but with pretzels, jelly, butter, fat free yogurt and beans to test for lipids, starch, proteins and glucose. After testing the foods, we chose a solid type of evidence and a liquid type of evidence to solve the mystery. We concluded that Kiara took Jarells iPod.
