This demonstration illustrates the vast amount of energy which is available from the oxidation of carbohydrates, such as sugar. An excess of oxygen, generated by the decomposition of potassium chlorate, will react with the glucose in a gummy bear, releasing a large amount of energy quickly and dramatically.…
When combining one gummy bear, which is composed mostly of sucrose with molten potassium chloride, a violent reaction occurs. A surprising amount of energy us released by the reactant, and in process, the atom and molecule rapidly rearrange to form 3 products(CO2/H2O and KCl). This reaction is said to be products favor. A favoured product reaction is where almost all of the reactants, react to form products. In this case its sucrose and potassium chlorate react completely to form carbon dioxide, water and potassium chloride. This reaction is exothermic, releasing energy in the form of heat and light (we can see flame a bright light during the experiment). The energy released is also equal to the calorific content of the Gummy- Bear. This reaction…
After researching, I found two studies that are similar to my experiment. One study by Sean Boyd (2007) tested to see which brand of microwave popcorn yielded the least amount of un-popped kernels. Mr. Boyd tested five brands of butter flavored microwave popcorn: Aldi, Act II, Orville Redenbacher, Jolley Time and Pop-Secret. His experiment proved his hypothesis partially wrong. Mr. Boyd hypothesized that Orville Redenbacher would be the best and Aldi's would be the worst. His experiment proved that Act II produced the least amount of un-popped kernels while Aldi's did have the most un-popped kernels on average.…
B. According to the colorists, the heat was produced by the ‘’ caloric’’ squeezed out of the chips…
This scientific experiment is to gauge the amount of kernels popped when the storage temperatures of the kernels are changed. Does freezing popcorn kernels for 24 hours yield more or less popped kernels than popcorn kernels stored at room temperature? By performing this experiment we can decide how to maximize our food potential. We will purchase six identical brands of popcorn from the local food store that have the same ingredients, weight and brand name. We will take three of the bags of popcorn kernels and store it in a standard household freezer for twenty four hours. The temperature of the freezer will remain at a constant rate of temperature. The other identical bags of popcorn kernels will be stored on a cabinet shelf and remain at a constant room temperature.…
In Sean Boyd’s experiment, he used six different types of brand Orville Redenbacher’s popcorn, Aldi’s “Corntown”, Act II, Jolly Time, and Pop Secret. He microwave for 2 minutes and 415 seconds. (Boyd, 2015) He thought the more expensive popcorn would have the lesser amount of un-popped kernels, and the less expensive would have the most un-popped kernels. But…

1. Candy bars are well known to supply large amounts of energy for metabolism. With all this energy trapped inside, how can the candy bar sit still on the shelf in the grocery store? Indeed, candy bars have a significant amount of carbohydrates (mostly simple, such as sugar) in their composition.…
Popcorn has a special design that enables it to pop verse other types of corn. There are many threats that can affect how popcorn pops. In order…
Carbohydrates and proteins have very similar energy yields, releasing about 17 kJ g−1. The values for fats are much higher, around 39 kJ g−1. The reason for this greater energy content is mainly due to the higher proportion of H atoms compared with C and O atoms in fat molecules. Most of the energy released by respiration is obtained from the electron within each H atom. Different tissues in the body tend to use different substrates.…
less saturated fat, 0 grams compared to 3 and 5 for 2% and whole milk.…
The purpose of this lab is to show that energy is transferred from food to other sources. This lab shows how energy travels from the Cheeto/marshmallow to the water inside the soda can using thermal energy. If we burn Cheetos or marshmallows, then the heat released should equal the calories provided on the nutritional label. When the Cheeto is sitting in the bag it has potential energy. Then when the Cheeto is burned the energy that is transferred to the can should also equal the energy that you would receive if you ate the Cheeto.…
The reason why we do not use hydrogen in balloons is because hydrogen is very explosive as shown in the Hindenburg accident. To summarized what happened to the Hindenburg there was leaking hydrogen. While the hydrogen was leaking there was electrostatic discharge. This was then ignited the hydrogen causing a huge explosion we still remember to this day. Although the Hindenburg was much bigger than any balloon this still would cause an unnecessary explosion that could hurt people.…
The purpose of this lab was to measure the energy content of three different food items using the change in water temperatures from the heat of the food. Another purpose was to take the information acquired and become familiar with energy units used in food such as calories and joules.…
Christina, I think having an art class would definitely require an unconventional classroom arraignment. Personally, I am not very familiar with how art classrooms are arraigned but it sounds like an open plan would be beneficial. I will be teaching social studies so I will use a variety of arraignments depending on what we are doing in class. It would be nice to have individual desks because I feel like those are the most flexible in terms of arraignment. On an average day, I will probably have the classroom arraigned with all desks facing the smart board and spaced evening in rows to have good flow, however, there will be times we push them together for group projects and when having a classroom discussion we will either do a circle or a…
