CHEETO CALORIE LAB

CHEETO CALORIE LAB
Our goal is to show how much energy is in a food sample by burning the food to heat water.
1 Place a piece of paper towel on the scale and tear it to 0. Put the cheeto on top of this and take note of the mass on the display
2 Shape the paperclip into a stand with a sturdy base and a wire end sticking straight up. Carefully spear the cheeto onto it, without breaking it
3 Measure 50 mL of water in a graduated cylinder and pour it into the can.
4 Place the can on the ring stand.
5 Measure the initial water temperature with the thermometer and record
6 Place the paper clip with the cheeto on it under the can and ignite the cheeto
7 Once the cheeto is done burning, measure the final temperature of the water and record.
You burn a Cheeto to heat the water to calculate how much energy is in the food sample

We got 79% error. Based on the percent error, we were not very accurate. We could have placed the can too close to the cheeto causing the temperature we got to be tampered with due to the burning can. We also could have touched the thermometer to the can instead of holding it in the water and actually measure the temperature of the can, not the water. If we could do this experiment again, we would have adjusted the height of the can above the cheeto, and checked to see what we were measuring the temperature of.
