Energy of Foods Lab 4th hour Chemistry I

Chemistry I students recently looked at the carbohydrate sugar glucose in the form of a marshmallow and compared it with the linoleic acid fat in the form of a tostito chip, cheeto, and peanut to see which molecule takes more energy to form and which one gives off more energy when burned.  Students created their own apparatus to hold the food below a pop can filled with water to measure the heat from the food and capture it into the can.  After many trials, student improved their apparatus to include a chimney to maximize the amount of heat flow.  Their designs and measurement skills vastly improved over the four day lab.  Here are some pics!
