Read the Calorimetry protocol on pg. 295 and 296.

1. What does a calorie measure?

2. Define calorie.

3. What does a simple calorimeter measure?

4. How can you calculate the amount of energy in food?



5. Write a brief statement about why you chose the 3 foods you did to test.




6. Write a hypothesis for your predictions about which food will have the most energy and
which will have the least. Make sure you write a WASL hypothesis.



7. Create a data table for your results. You will be testing 3 different foods and will need to
record: starting water temperature, starting mass, final water temperature, final mass. You
will run 3 different trials for each food. You must also test coconut and cashew. Please include
those on your data table.




8. Follow the Steps to the Calorimetry Protocol starting on page 296 to test your foods. Put
your results in the table you created above.
9. Analyze your results. You will use step 18 (p.297) in the protocol box to analyze your
results. You will create another table to record your answers from calculations you make on
the three foods you tested. Your table must include: average temperature change, average
number of calories, average kcals, and kcals per gram food.




10. Find the actual number of calories per gram for each food using the food package or using
the internet (www.thecaloriescounter.com is a good site.).




11. Write a CPR2 for this lab activity. This will be turned in to Mrs. Ogden (do NOT put it in
your journal!)
