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:

Crisp bread
Dried peas

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
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.
Calories are a measurement for energy and are often measured as the heat energy absorbed from the digestion of foods (“Calories.”). Calories seen in labels of food are not measured in heat energy, but as estimated comparison of energy density (Atkins). Despite that calories are used as measurements of the energy in food, it is not the only thing t...
Wanting to address the everyday consumer needs of safe cooking and electricity for those live in provincial societies, Bright Light Innovations of Colorado State University have developed a new product in which their management team of Business and Engineering students’ have considered as a definite solution through their revolutionary product—called the Starlight Stove. From identifying the everyday issues that people face in third world countries, the Bright Light Innovations team then identifies Nepal as their opening target market; in hopes that the Starlight Stove can improve the quality of life and well-being for those less fortunate. To benefit the lives of Nepalese, the Starlight Stove features the unique ability to convert heat from
In “Barn Burning” by William Faulkner, follows the protagonist, Colonel Sartoris Snopes, also known as Sarty, a small, wiry 10 year old boy who has inherited innocence and morals from his mom, while attempted to be taught loyalty above all from his father. As well as his father, Abner, a serial arsonist who is cold, violent, and values loyalty. Also Sarty’s mom, Lennie, who is emotional, caring, and seems beaten down from the constant moving due to her husband’s illegal activities. The story follows them as they are run out of town due to Abner burning down someone’s barn because of dispute over escaping farm animals. While he is not convicted, they are forced to leave town. When they find a new home and place
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.”
Family is a very dominate aspect in the stories that were read for this class. Especially in William Faulkner’s story, “Barn Burning,” where the blood should bond a family together forever no matter what happens. In F. Scotts Fitzgerald story of “Babylon Revisited,” a man wants to get his daughter back. In both of these stories each man experiences a sense of loss. In the barn burning, the love between a father and a son should be based on genuine respect, love, loyalty, and admiration. This is not what happened. Blood was the most important aspect. Throughout this story the boy just wants to gain his father’s admiration, but in doing so he loses his blood tie with his father. In Barn burning, Sarty’s father is being tried, but since there is no evidence to prove that he did it, he is ordered to the leave the country. A very harsh image of Sarty’s father is presented when “he followed the stiff black coat, the wire figure walking a little stiffly from where a Confederate provost’s man’s musket ball had taken him in the heel on a stolen horse thirty years ago. ” His son, knows that his father has never been a law abiding. Therefore the bond between them has been broken. It is hard for Sarty to have a sense of loyalty to his father and to do what is right especially when he knows that his father’s actions are wrong. Sarty alludes to Mr. Harris as “his father’s enemy (our enemy he thought in that despair, orn, mine and hisn both! He’s my father! ” Even with the accusations that were against his father Sarty still feels like he should protect his father. “The old fierce pull of blood” is what is preventing him from turning in his father. So here the Sarty is very torn on what he should do, but the blood binding between is father and h...

Abstract: Marshmallows have more Calories per gram. Marshmallows have .2079 J/g℃ and cheese puffs have 1.08x103 J/g℃. My hypothesis was that marshmallows have more Calories per gram and my results confirmed my hypothesis because there is a .2068 J/g℃ difference.

Investigating Factors Affecting the Heat of Combustion of Alcohols PLANNING SECTION Introduction ------------ Alcohols are organic substances, and consist of Hydrogen, Oxygen and Carbon. All alcohols are toxic but the amount that can be tolerated by the human body varies for different alcohols. For example drinking small amounts of Methanol can lead to blindness and even death.
Carbohydrates and lipids/fats are a very important part of our lives. They have many similarities
“Where they burn books, they will, in the end also burn people.” (Henley, 2) I believe this quote is absolutely true. Books are people's way of expressing themselves and their thoughts. It's a way of getting a message across. So ultimately the people that burn books end up burning the people. Maybe not literally, but you hurt their feelings and sense of confidence they had about putting themselves out there.

2574) Knowledge of the energy density of foods is a large part of being able to maintain a healthy diet. High energy density foods contain a lot of calories in a small amount of food, while low energy density foods contain a low amount of calories in a large amount of food. (CITE) According to the CDC, “Fat increases the energy density of foods, while water and fiber decrease energy density. Water has the greatest impact on energy density because it adds weight to food without increasing calories, thus decreasing the energy density. Most fruits and vegetables are low in energy density because of their high water and fiber content and their low fat content” (Can, n.d., p. 3). “Eating low-energy-density foods promoted moderate weight loss. In studies lasting longer than 6 months, weight loss was 3 times greater in persons who ate foods of low energy density (low in fat and high in fiber) than those who ate simply low-fat foods” (Can, n.d., p. 3). “Can Eating Fruits and Vegetables Help People to Manage their Weight?” an article from the CDC, describes how diet intervention programs where participants are instructed to specifically incorporate more fruits and vegetables lost more weight and maintained a lower weight as compared to groups that were instructed to lower high fat and high sugar foods (Can, n.d., p. 3). This finding supports the theory that low density foods are crucial to maintaining
