Welcome to my user-friendly version of the classic calorimeter lab for high school biology, chemistry, or physical science! I started out facilitating a Prentice Hall version of this lab back in the mid-1990s at my first school. I have continued the tradition of facilitating this lab in my biology classes the last couple of decades, implementing improved versions of this lab every year. As stated earlier, this lab also has direct interdisciplinary ties with the other sciences, notably with the thermal energy unit in physical science and in a biochemistry unit in chemistry.
This listing features a three-page student calorimeter lab sheet and a three-page key with the standard answers in red font.
Students fill in the open sections of the lab sheet and submit it for the lab report. In my version of the calorimeter lab, students will:
· Write a hypothesis
· Record observations in a data table
· Write a conclusion with consideration of the variables that may have affected the
results such as student error
· Restate the hypothesis in the conclusion and state whether it was correct, partially
correct, or incorrect
· Analyze the nutrient label to explain the macromolecule content per serving for
each sample of food in relation to the Calories burned
· Use the provided equations to calculate the kcal and then the kcal/gram (Calories)
for all three samples of food
· Practice safe lab procedures
The facilitating teacher will need the following supplies standard for this lab for each lab group:
· Small box/set of matches
· White marshmallow
· Cheese puff
· Access to a digital balance
· 100-ml beaker to measure 50 ml of tap water
· Ring stand
· Circular clamp
· Glass stirring rod
· Empty soda/pop can with an intact tab
· Large cork wrapped in aluminum foil with a pin or a half of a straightened-out paper
clip sticking upwards from it
· Plastic weigh boat or filter paper on which to mass the food samples
· A set of lab aprons and safety goggles
· The nutrient label on the manufacturer’s package of the three foods for student
In this lab, students will test their hypothesis by experimentally determining the change in mass to the food samples and the temperature change to the water suspended above the burning food sample. Students will then use that data to calculate the kcal and the kcal/g (Calories) released upon the combustion of food. The food sample choices may be altered.
The lab questions also direct students to record experimental (student) errors and how the macromolecule content per serving of the food samples affected the number of Calories burned.

I began launching my curriculum line through TpT in 2018. I have over twenty years of teaching and curriculum writing experience as the department head. I joined TpT with seventeen years of publishing experience.
