Discussing the energy content of food can lead to discussion of body mass and weight loss which is a sensitive area for many students. SAFETY: Check in advance if any students have known food allergies. Ensure none of those allergens are used for the procedure by any group. Normalize the caloric content of food items to the caloric content of one food item. Under normal circumstances, more than 95% of this food energy is digested and absorbed from the gastrointestinal tract to provide the body's energy needs. spotify star wars easter egg Step 1. Create a graph, listing the food items on the x-axis and the caloric content of 1 g of food on the y-axis. There are no safety hazards with any of the materials used in this experiment. Calculate the energy value using the formula: Energy value = 4.2 (Jg -1 o C -1) x mass of water (g) x increase in temperature ( o C) / Mass of peanut (g) Procedure. g As soon as the food is alight, put it under the boiling tube of water as shown. 3) In this experiment, you will use various foods: a peanut, cheeto, mini-marshmallow. The equation for calculating kinetic energy is: kinetic energy = 1/2 mv 2, where m is the mass of the object (in kg) and v is the velocity of the object (in m/s). Heat the food until it catches fire. From the experiment setup and data collected, students will have the evidence necessary to construct a model of heat transferred through the reaction of food with oxygen. Total Energy = Volume of water x (initial temperature -final temperature) x. The Calorie you see on a food package is actually a kilocalorie, or 1,000 calories. 4.
