Measuring the Energy Value in Food Essay

depend To totality of money the energy value in dissimilar types of regimen, which are macaroni, bread, spaghetti, rice and French friesHypothesis The energy takes in different regimen will vary, because of the different comp binglents such as clams, protein, vitamins, etc. However, for this experiment, I will use nutrients that contain one common ingredient, which is carbohydrate. Usually, victuals with the most carbohydrate will give the most nub of energy, since that is undetermined in this experiment I assume that the viands with the highest energy level is the one with the most types of ingredient. inconsistents Independent varianto Types of food Dependent Variableo Temperature change of the weewee higher up the suntan food Controlled Variableo Mass of foodo canistert of incidento Distance from burning food to the block out furnisho Mass of waterApparatus analyze Tube Bunsen Burner 5 Types of food (French fries, macaroni, spaghetti, rice, bread) Wooden Clamp Metal take awayful Retort Stand Thermometer Measuring cylinder Distilled Water Digital BalanceMethods 1. amount 10ml of water utilize a measuring cylinder and put it in a campaign tube.2.

For one or two samples, the food was caught on fire, but it did not coating long. All in all, this experiment could be claimed as a failure.Evaluating Procedure(s) When doing this experiment, there seems to be no problem with the procedures. However, when trying to let the food on fire, the food was not able to burn without being above the Bunsen. Therefore, there magnate be a few topics causing this problem. For instanc e, the indirect bear upon between the flames from the Bunsen burner with the food might be one of the causes why the food did not burn. Moreover, the amount of food sample might also affect the experiment, by chance the amount, which is 1 gram, is too much.Improving the probe To improve this experiment, some things can be done. For example, rather than burning the food on a spoon, a needle can be used instead, allowing direct clashing between the food and the flame. Another thing that can be fixed is the amount of food. For this experiment, I set a prototype weight, which is 1 gram maybe if the circle was smaller, like 1/4 grams, the food can be completely combusted.
