Jelly Experiment Lab Report

Purpose: The purpose of this gummy bear lab is too figure out what different types of osmosis and diffusion can be seen during the lab. Also too see what solutions will cause the gummy bear to be isotonic, hypotonic, or hypertonic. This will benefit people that may eat a lot of gummy bears along with drinking sodas and juices, or water this may cause you to become more dehydrated. This will help people who like to eat gummy bears but don’t know what's best to drink with them.

This project, while not an extremely significant one as far as impacting the populace, was completely born out of curiosity, and turned out to be an interesting study. This project is on skittles. People may be thinking, why skittles? This whole semester, statistics students have been solving problems about M&M’s and while that was interesting, skittles candy are more interesting. The main reason for choosing skittles over M&M’s or any other candy is that skittles have different colors. M&M’s do as well, but while both have different colors on the outside, each different color of skittles has its own unique flavor in the inside. The green color is lime flavored, the yellow is lemon, the purple is grape, the red is strawberry, and as conventional wisdom would say, the orange is orange. Throughout this study these terms will be interchangeable. This observational study asks the question, how are skittle colors distributed per package?

In the Gummy Bear Lab, the scientific method is used throughout the process. The first step of scientific method is observation, in this case I observed how a gummy bear’s density will be affected. Second step, was to state a hypothesis on how the water will affect the density of the gummy bear overnight. In addition, my hypothesis stated, “ If the gummy bear absorbs the water overnight then the density will increase.” Next step was to gather materials to prepare to perform an experiment in the laboratory. The materials used were the following: a ruler with centimeters, balance scale, graduated cylinder, gummy bear, and a small cup of water. Then by using the materials, measurements of the gummy bear were recorded such as the length, width,

In this lab, different colored M&M’s were compared in order to find out if all M&M’s are created equally. Peanut M&M’s are peanuts that are dipped in milk chocolate and covered in a thin candy shell that comes in different colors. These M&M’s are produced and packaged at Mars, Inc. Each group was given 10 Peanut M&M’s of one specific color. The mass of each M&M was found using a scale and rounded to the nearest hundredth of a gram. Then the mass of the M&M’s was used to calculate different statistics such as the mean, median, mode, standard deviation from the mean, variance, standard error of the mean, and T-Tests.

In order to obtain a random sample, three bags of M&Ms were purchased from different locations. Each bag of M&Ms was a 1.69oz bag that was the standard plain version of the candy. The M&Ms were then sorted by color and this data was collected and compiled. These results were also added to a larger sample

The purpose of this experiment was to see if brownies could taste the same, appear the same, and have the same texture if you didn’t use the key ingredients to brownies. The key ingredients to brownies are eggs, water, and oil. The brownies were also cooked at a different temperature, to see if the brownies would cook the same. There were three different test tasters, they predicted different things and said different things about the brownies.

Jelly is made from protein, gelatin, this is dissolved in hot water and as it cools, it sets. For a childrens party it was decided to make some fruit jellies, these were made by putting sliced pineapple into the jelly before it set, the following observations were made:

In previous studies, Frank and Byram’s article suggest that taste and smell interactions are dependent on taste and odor. In their experiments, they gave subjects strawberry

The expression of phenylthiocarbamide is very questionable concept given such a diverse and vast population of people living on earth with only a 0.1 of difference genetic. Phenylthiocarbamide is white fine powder that when ingest an individual can taste bitterness or nothing. In the mouth, there is gene called TAS2R that encodes for bitter taste receptor. The experiment will test the expression of TAS2R gene using phenylthiocarbamide or PTC on a selected population of Florida International University students for the recognition of bitterness or absent. Twenty-four undergraduate students of Florida International University will be participating in the experiment where height, age, sex, and ethnicity is negligible.

The season for fresh fruit is quickly approaching as weather conditions continue to improve. Fresh fruit is a beautiful and exciting way to incorporate important nutrients into the daily diet. Unfortunately, fruit does not stay fresh forever, so it useful to know how to properly preserve fruits to keep them safe and nutritious.

The experiment variable in the “Jam Experiment- Choice Overload” is the number of jams displayed. Another experimental variable can be the value of the coupon. Researchers are able to change the amount of jams displayed at each condition as well as increasing or decreasing the value of the discount coupon they are giving out. The dependent variable is the customers’ attraction to taste, as well as the purchasing behavior.

In conclusion, the fifth trial was the fastest. All of the M&M trials took under two and a half minutes to wash off the color. My hypothesis was wrong because I had thought that the mixture would take about four minutes to wash of the color. What could have messed up my results was the amount of water and acetic acid I had put in the small beaker. A question that I have now is that if I had put less water and acetic acid would it have slowed down my times?

In a land far away there was a kingdom, this kingdom was deemed the jelly kingdom. mainly because all of its inhabitants were made entirely up of a jelly like substance. Many citizens lived in this kingdom, mostly peasants and higher political figures but on top of them all lived the royal family. this family was made up of the queen, queen Alexandra and her son prince Pink. in recent years there had been a small battle between two kingdoms, the jelly kingdom and the fire kingdom. over time, the battle had evolved into a full-on war, it was known to all as the great rival war. in the midst of battle the late king, King Augustus had lost to a fire knight. There was a great mourning over his death, it was a sad day for all.

Trying new foods and having a good experience -- one that does not cause adverse effects -- allows for the individual to obtain learned safety that reduces neophobic behavior. This phenomenon, called the mere-exposure effect, allows not only for positive responses to specific foods but also to generalized positive responses to similar foods (Preedy, Watson, & Martin, 2011). As expected, exposure to a palatable novel foods increased an individual’s willingness to taste a different novel food, while exposure to a bad novel food neither increased nor decreased the individual’s willingness to try a different novel food when compared with control groups (Pliner & Salvy, 2006). Development of a food aversion requires only one exposure in which the individual experiences a negative physiological reaction. On the other hand, an average of ten exposures are required to reduce avoidance of a novel food. Since FN is on a continuum and each individual has varying degrees of neophobia, some may require less or more exposures to overcome stigmas against novel foods. It was also found that as the individual broadens their palate, fewer exposures are needed to decrease FN (Preedy, Watson, & Martin,

The overall purpose of the lab is to have the students practice designing an experiment, gathering data, and then analyzing that data to form a conclusion using the scientific method. It also served to understand key terms such as hypothesis, dependent variable, and independent variable. The specific objective of this lab is to determine whether certain human body parts experience allometric or isometric growth. Allometric growth defines when certain parts of an organism grow at unequal rates in comparison to its whole, while isometric growth is when all parts of an organism grow at the same rate in comparison to the entire organism. The specific purpose of the lab is to determine whether or not specific human body parts experience allometric or isometric growth by comparing the ratios of height to two specific body parts, in the students’ case the right hand length and head circumference, in students and newborns. The students formulated the tentative answer that if a team of four compared their height to right hand length ratio, as well as, their height to head circumference ratio, to those of a newborn’s, then the students will discover that the right hand and head experience allometric growth in humans.
