Calorimetry is the science of measuring the change of energy involved in a chemical process. There are many different designs of calorimeters, but each is devised to measure the heat that is either released or absorbed during a chemical reaction or phase change.
Eisco Lab's Food Calorimeter Kit allows students to determine the amount of energy released through the burning of food. This easy-to-use method involves measuring the change in temperature of a sample of water from the combustion of a small amount of food. The included experiment introduces concepts in thermodynamics and leads to an understanding of energy and its relation to food consumption.
Students can determine the energy caloric content of a sample of food using thermodynamic equation. The stored energy inside the food sample burns and is converted into heat energy which transfers to the water in the flask above. The temperature change of the water is used to determine the amount of heat that was absorbed by the water, and thus the amount of heat released by the burning food. By dividing the amount of heat transferred by the amount of food burned, students will be able to find the energy per gram in the sample, and then compare this to the food's nutritional label.
Included Components:
- Erlenmeyer flask (200ml capacity)
- Cylindrical metal stand
- Metal suspension plate
- Cork & nail food holding assembly
- Rubber Stopper
Required but not included:
- Matches or lighter
- Thermometer or temperature probe
- Digital scale with 0.1g accuracy
- Food samples (e.g popcorn, nuts, chips, cereal, croutons. Dry food with some fat content works best)

Worst apparatus to be added to a food calorie experiment.Definetly, DOES NOT WORK.

It came dirty with what seems to be some kind of toxic contents.

Used it for my sister's science fair experiment, setup is a little odd since you have to handle a hot flask at times, buttttt it gets the job done

Kit is reasonably priced and good for a middle school project. Recommend wrapping the cork in foil paper to prevent it catching on fire.

The setup is a little awkward because you have to handle a hot glass flask, but for the money it's great. Used it for biology class.

Everything you need for a science project - such as finding the number of cals for a particular food. We were going to order ours through a science fair/science olympiad website but it would take weeks for it to be delivered. Via amazon prime it was two days. The kit comes with a small booklet with step by step instructions on how to conduct the experiment. Everything is shipped in a box: 200ml capacity heat-proof glass flask, metal stand and plate to hold it up, cork and pick to hold up the food sample, and a rubber stopper to holding in the thermometer. The thermometer doesn't come with the kit but is needed for the experiment. We bought a generic one on Amazon and while it was tight and a little tall, it worked perfect for the project.

I think this is such a great kit. It came with a little paper that you can unfold, and on that paper, it tells you the equations to calculate the amount of calories in the form of an equation. It tells you the science behind the project, and even has outlines for a graph and analysis, and shows you the exact procedures. It tells you how to compare the calorie content to the amount listed on the Nutrition Facts label on the boxes. Basically, it told me everything I needed to know to do my project, and showed me the steps for the other parts of the project such as the analysis, conclusion, etc. This project kit is great. However, the experiment paper says that you also need a temperature or thermometer probe, a digital scale with 0.1 gram accuracy, and matches or a lighter. Make sure to get these ahead of time, along with whatever food sample you desire. Dry food with some fat content works best. Ex: popcorn, nuts, chips, cereal, croutons. this experiment kit was simply incredible, and I recommend it to anybody looking for a good science project. Five out of five stars. :D
