Measuring the Energy Value in Food Essay

Aim To measure the energy value in different types of feed, which are macaroni, bread, spaghetti, rice and French friesHypothesis The energy levels in different food will vary, because of the different components such as dinero, protein, vitamins, etc. However, for this experiment, I will use foods that contain one common ingredient, which is carbohydrate. Usually, food with the most carbohydrate will give the most tally of energy, since that is undetermined in this experiment I assume that the food with the highest energy level is the one with the most types of ingredient. variables Independent Variableo Types of food Dependent Variableo Temperature change of the water above the editing food Controlled Variableo Mass of foodo Angle of incidento Distance from burning food to the test tubeo Mass of waterApparatus Test Tube Bunsen Burner 5 Types of food (French fries, macaroni, spaghetti, rice, bread) Wooden fasten Metal Spoon Retort Stand Thermometer Measuring Cylinder Disti lled water supply Digital BalanceMethods 1. standard 10ml of water using a measuring cylinder and put it in a test tube.2. fasten the test tube on the retort stand for 45o and measure the temperature of the water in the test tube, line of descent it down.3. Weigh the food sample for 1 gigabyte and record it down.4. Place the food on a metal spoon and light it on fire using a Bunsen burner.5. When the food starts burning, come in it 1 cm below the test tube, if it goes off, light it as soon as possible.6. When the food kale burning, measure the temperature of the water in the test tube and note it down.7. Repeat the experiment for 2 much times for each food sample.Recording Raw Data Table of Initial and Final Temperature of Water for Each nutrition SampleFood SampleInitial Temperature (oC) 1oCFinal Temperature (oC) oCSpaghetti24Macaroni25rice24Bread24Processing Raw Data and Presenting Processed Data Table of Temperature switch of Water for Each Food SampleFood SampleIniti al Temperature (oC) 1oCFinal Temperature (oC) 1oCTemperature Change (oC) 1oCSpaghetti24Macaroni25Rice24Bread24Table of Energy Values in FoodFood SampleTemperature Change (oC) 1oCMass (g) 0.01gSpaghetti1No consequenceMacaroni1No solutionRice1No solutionBread1No solutionConclusion For this experiment, it turned out that the food sample was not able to catch on fire, causing flame on hand(predicate) to increase the water temperature in the test tube. For one or two samples, the food was caught on fire, that it did not last 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 get the food on fire, the food was not able to burn without being above the Bunsen. Therefore, there might be a few matters causing this problem. For instance, the indirect play between the flames from the Bunsen burner with the food might be one of the causes why the f ood did not burn. Moreover, the amount of food sample might also affect the experiment, maybe the amount, which is 1 gram, is too much.Improving the investigation 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 contact between the food and the flame. Another thing that can be fixed is the amount of food. For this experiment, I set a standard weight, which is 1 gram maybe if the mass was smaller, like 1/4 grams, the food can be completely combusted.
