Table 4: Calorie Testing
Initial Final
Mass of Marshmallow
Temperature
1. Calculate the thermal energy in the burnt marshmallow based on the following information:
2. Is there a relationship between the final mass of the marshmallow and an increase in temperature of the water
inside of the can? If so, explain your experimental observations.
3. What is the purpose of cutting the marshmallows into four quarters? How might the experimental results have
changed if the marshmallow was burned in one piece?
4. Based on the design of the experiment and on your percent error, would you have designed this experiment differ–
ently? Explain why or why not, and if applicable, how you would design it differently.
5. Does toasting bread change the amount of calories in the bread (i.e., does a slice of toast have more/less calories
that a slice of bread)? Explain your answer using the data in Table 4.
