The purpose of the experiment was to take foods and to find out the energy content of the foods that we are experimenting with. By hands on burning or the food and taking the date that we find and putting it into equations to find what is needed. Procedure
After organizing all the equipment necessary to perform the lab correctly and safety, I placed the empty beaker on to the scale and recorded the weight. Then I filled the beaker with 50 ml of water and measured it and recorded my results. I then place the beaker onto the burner stand. I took the temperature of the water before heating it up. I first started with the marshmallow. I put the marshmallow onto the fork and measured its weight. Then I lit the marshmallow on fire and place it under the beaker. After the flame was extinguished I measure the temperature of the water and recorded it. I then place the remains of the marshmallow and fork onto the scale and recorded my findings. I proceeded to do the same thing with a walnut and then with a potato trip and recording the results of each.
