Driving question : How much energy is there in food?
This is an activity in which different student groups can investigate different items of food. A sample of a food of known mass is burned, heating a calorimeter. Students record the temperature of water heated in the colorimeter, calculate the energy transferred to the water, and hence estimate the energy present per unit mass of food.
