Heat Food Lab * Purpose: * Understand how to calculate calories per gram from burning food in the laboratory. * Understanding how to use the food nutrition label on the back of the package to calculate the calories per gram. * The calculated calories per gram in the laboratory are compared to the calories per gram that were calculated from the nutrition label.
Then the % error and % yield are calculated and displayed in table and in a graph. * Students will be able to create a laboratory report in MS word and a MS power point. * Students will to be able to create a data tables and graphs through Microsoft Excel. Hypothesis: If a better calorimeter is built after each trial, then the % error will decrease and the % yield will increase. * Independent variable: The Initial mass of a Cheeto,The End Mass of that cheeto, The initial temperature of the Water, The End Temperature of the Water. The Amount of Water that is used in the Experiment( Soda-Can) * Dependent variable: The Percent Error, The Percent Yield, calories per Gram.
* Trials: 3 sets, And 3 Trials for each set; Total of 9 Trials * Constant: Shape; Form of the can, Glass Flask (200 ml), Form/ Shape of the Thermometer. Control: The Accepted Value Calories (160000), Grams Per Serving (28g), calories per Gram ( 5714): Estimate] Part 1 Table 1:Data| | Temp Initial| Temp.

This method only gave us inaccurate results and we had to develop a better System, Rig or Build. The Reason why we were unable to achieve better Data, was that we were losing heat from multiple attempts of burning. C C In our Second Set we’ve made Way a Better Calorimeter, We’ve used different materials, Also we’ve used two cans, and Even used Aluminum Foil.
Set 2 Can BC A Set 3 Can In our third set I’ve built A calorimeter that’s different from the Other two That I’ve made. With this we were able to achieve much better results and more idea’s added onto the experiment. | %Error| %Yeild| Part 1| -88. 8865| 11.
11349| Part 2| -83. 8951| 16. 10493| Part 3| -67. 3464| 32. 65363| Graph Paragraph The Graph Above is measuring the differences in the Accepted, Average, and measured Values of this experiment.
I’ve set the Graph in an orderly fashion, only using one graph for both the Percent Error and Percent Yield.I’ve achieve both Very Low and Very high Values in Both Percent Error and Percent Yield. In percent yield the Lowest Value in 11. 11%, in percent error the highest is 88.
88%. The Trend I’ve noticed In this experiment would be the Positive trend shown in the Graph(s). In the End I realized that Building a better Calorimeter will only set you off in many different directions, Although in all of My Trials, I did achieve better results. Conclusion This Experiment was to Understand how to calculate calories per gram from burning food in the lab.The major findings Of the entire experiment was that I had found that You can possibly Boil Water While using Chips as your source of Fire.
The Data did approve and It definitely helped my whole experiment. I didn’t expect the Spontaneous Burnings, to produce that Much Smoke, I really think that most of the smoke came from burning the tape, or the can itself. Anything to improve this experiment would be the use of better materials and something better than a Tin Can. For further Studies I’d recommend a Clean workspace, Better tools and Much more Fluent Burning in this Experiment.
