Introduction: We decided to conduct this experiment so that we could find the amount of energy that is in certain foods by burning them and measuring the amount of calories released. By doing this I hoped to learn what kinds of foods would be the best to eat to make my diet more efficient. By finding the amount of calories released from the food in the form of heat energy I could find out which foods contained the most potential energy. Before I started the experiment I hypothesized that the peanuts would have the most energy inside of them because they have the most fat in them out of the 4 foods that we used in our experiment (marshmallows, popcorn, peanuts, and cashews).

Dependent variable: The amount of heat energy given off by selected foods.

Independent variable: The different foods selected for the experiment.

Constants: The room temperature, the pop can, the water was always chilled, the scales we used to weigh the pop can and the food, the amount of water was always 50 ml of chilled water for non-fatty foods (marshmallows) and 100 ml of chilled water for fatty foods (peanuts and cashews), we always used a match to light the
