An Investigation on Burning Food
Planning
Aim:
The aim of this experiment is to determine the effect of differing
amounts of fat in the food on the amount of energy per gram or 100
grams in the food.
Scientific Knowledge:
Here is the table of quantities of different nutrients in food:

This table shows that the food with the most energy inside of it is
pumpkin seeds. They also contain the most protein but the least
carbohydrates and also contain the most fat than all the other foods.
The table also shows that dried peas has the least amount of energy
but does not have the least protein, carbohydrates or the least fat
compared to the other foods being used in the experiment.
One gram of fat produces twice as much energy as a gram of
carbohydrate or protein.
The temperature change in water is caused by the absorption of heat
given off by the burning of a known mass of food. Based on the change
in temperature, you can calculate the amount of energy in food.
If the room heats up more, this will not have an affect on the results
because the water is hotter and so the results will not be higher than
usual. It just means that the results will be the same but the initial
starting temperature of the water will higher.
Carbohydrates give off the most energy because they contain the
In the experiment, 0.436 Calories per gram were found when dividing the average heat per mass of food by 1000. The standard deviation proved that this number can either be moved up 0.082 Cal/g or down. This is nowhere near the 3.2 Calories per gram which appeared on the label
Catching Fire: How Coooking Made us Human by Richard Wrangham is a fresh perspective on the evolution of humankind. Wrangham has made a concentrated effort to prove that humans have evolved particular adaptations, like bipedalism, due to the introduction of cooked foods into their diet. In his book, he is legitimately arguing that humans are the way they are because early on in human evolution, early man discovered fire, discovered the joys of cooked foods, and developed all sorts of fascinating traits still being utilized today.

In “Barn Burning” the setting is a time when people drove horse wagons and the workingmen were generally farmers. The major character in this story is Colonel Sartoris Snopes, called “Sarty” by his family who is a ten-year-old boy. In the beginning, Sarty is portrayed as a confused and frightened young boy. He is in despair over the burden of doing the right thing or sticking by his family, as his father states,” You got to learn to stick to your own blood or you ain’t going to have any blood to stick to you.”
Words have so many different meanings. Just pick up a dictionary to discover the many different meanings of the same word. Have you ever wondered where the meaning of the word originated? Maybe you have asked what a word means when another has used it out of context. How did one word come to mean so many different things? This paper will allow me to explore the definition of burn and where it originated. I will also discover how it has changed over the years and what the definition is today.
A book that fully illustrates the hardships of dealing with the reconstruction of a nation after an era of slavery as well as concisely providing insight to a strong civil rights voice is “The Fire Next Time” by James Baldwin. His writing is a both an examination of race relations in a segregated America, and an impassioned plea for both whites and blacks to abandon the hate and embrace love as an outlet for their differences. The title of the book comes from an negro spiritual quotation that Baldwin directly relates to the inevitable consequences of continuing racial injustice: "God gave Noah the rainbow sign, No more water, the fire next time!"
William Faulkner’s ‘Barn Burning’, is the tale a young man, by the name of Colonel “Sarty” Sartoris Snopes and his father, Abner “Ab” Snopes, and the difference between right and wrong. The story commences in a courtroom, where Ab is on trial for burning a barn. Young Sarty is called to the stand to testify as to what took place, until the plaintiff told the judge he didn’t want him to question the young child. However, Sarty was unsure of the decision he would make if he was questioned. Sarty was unsure if he would choose his loyalty to his father, or if he would do the noble thing and tell the truth. Sarty and Ab’s relationship was strained with abuse, anxiety and fear, Sarty’s devotion to Ab never reciprocated, until Sarty makes the most
The poem “Bananas on Fire: The Virgin’s Guide to Surviving Automatic Heat Death” was written by Isiah Fish and appeared in the 2013 edition of the Zephyrus, Western Kentucky University’s creative writing publication. This poem is incredibly well done with many strengths and only one weakness as far as I can see. It is about the innocence and perversion of youth, the loss of virginity later in life, and even the future beyond. Fish’s writing style and frank diction speak directly to the reader. I believe it is one of the best poems, if not the best one, in the publication.

For the sample calculations, let’s use the marshmallow as an example. Its initial mass was 0.66 grams and its final mass was 0.36 grams. To calculate the amount burned, subtract 0.36 from 0.66 to get 0.30 grams. (Mass burned = mi- mf). To find the marshmallow’s change in temperature, use the formula (ΔT =
