Nearly everything you eat or drink has calories, (except water) it is the unit we use to measure the energy we get from our food. A calorie is the amount of energy it takes to raise the temperature of 1 gram of water 1 °C. We can calculate the calories in everyday food by burning the item and monitor how much the temperature of 1 gram of water rises. The students took the mass of the glass dish, paper clip and chip and recorded their results. Then they took the starting temperature of the water and recorded the results. The student then lit the chip on fire and watched the thermometer to see the highest temp recorded. When the temperature stopped rising they recorded that temperature. Then they calculated ΔT (change in temperature) and calculated the total amount of calories in a single serving of their favorite food item.
