Topic: Economic Impact of Obesity in the United States.
Health is a broad topic in which I am interested. Health falls under the discipline of Sociology. I am interested in this topic because Sociology is my major, and Health is one of my focuses in this social science discipline. Therefore, researching “Economic Impact of Obesity in the United States” will broaden my Sociology knowledge and other social science disciplines.
The topic I have chosen is inherently social, considering it is about the health of people. Besides, it is a social problem since it negatively affects a large population, and it is an issue that needs to be addressed. Obesity is a serious social problem in the United States since it is associated with reduced quality of life, mental health problems, it is one of the leading cause of deaths in the US, and it is related to high costs (medical costs, transportation costs, productivity costs, and human capital costs).
I am going to approach this topic in terms of an economic sense. The disciplinary approach suited for this question I am researching is Sociology and Economics. It fits these two disciplines because it is about the health of people and economics.

After your topic is selected and approved. (1) Abstract: should include your research questions, the theory (AJ 100 or 105 will help) or theories that inform your research, the methods of data collection and analysis (see AJ 301/2) to be used, and what you believe you will find as a result of your study (see course objectives). (2) BODY: After you have identified a specific topic, you will then develop your own unique area of discussion and analysis: introduction, literature review, theory and methods, and possible finding (your previous courses in AJ will help such as AJ 100,105, 211,240, etc.). (3) Citations: You must use the APA guide for identifying authors cited in the text as well as the bibliography listing all sources used in alphabetical order. If you are not familiar with APA, there are reference guides in the library as well as on-line sources. (4) Placement of graphs, figures, or tables: If you use graphs, figures, or tables in your paper, I would prefer that you note their location in the text, [TABLE 1 HERE], and compile all tables at the end of the paper. This is easier for both the writer and the reader. (5) Format: Papers must be type, double spaced, with one-inch side, top, and bottom margins and use a 12-point font. A cover page with the title and your name is sufficient. The minimum page requirement for the paper is 15 pages (NOTE: cover, reference, graphs, figures and, tables pages will not be counted as part of the 12 pages). While I do not specify a maximum length, I am anticipating that most people will submit papers 12 pages long.
PAPER CHROMATOGRAPHY LAB REPORT

Introduction
Paper chromatography is a separation technique that utilize a solvents’ ability to carry with it a dissolved solute on a strip of absorbent material. It utilizes the principle of chromatography in which the mobile phase (solvent)carries the solute across the surface of a of an immobile phase (the cellulose on the paper) while depositing pigments of the solute on the rough surface of the paper.
Requirements
-Coffee paper
-Scissors
-4 Glasses of water
-Food colouring
-Pencil
-Ruler
-Toothpicks
Procedure
The coffee filter paper was folded into four strips of one-inch widths then cut along its length to come up with four paper strips. Each of the strips was then marked with a pencil leaving a one-inch allowance on both ends along its length and then impaled on one end with a toothpick. The strips were numbered 1 to 4. A drop of pigment was then dropped on the lower margin of the strip of paper with each strip getting one of the dyes. The strips were then suspended on the rim of the glass so that they were clear of the sides. Water was then added to the glass just so that the lower edge of the paper strip was touched. The experiment was then left to stand for 20 minutes then observed. The heights of the resulting strips and highest level reached by the water on the paper were measured by the ruler and tabulated on the table below. All heights are in centimetres.
Results
Spot colour Spot heihgt from origin Solvent height from origin Retention factor value
Food colour Red Red 3.30 cm 8.80cm 0.38
Pink 6.20 8.80cm 0.70
Green Yellow 6.80 8.80cm 0.77
Blue 4.00 8.80cm 0.45
Blue Blue 4.30 8.80cm 0.49
_ _ 8.80cm _
Yellow Yellow 6.60 8.80cm 0.75
_ _ 8.80cm _
The retention factor for the individual dye was then calculated by dividing the spot height and the solvent height and results tabulated.
Conclusions
The experiment was a success at determining the respective pigments within the four food colouring dyes. There was a corelation between similar pigments on different dyes and their retention factors a pointer to the fact that they might be similar in constitution.
Post lab questions
1 Types of chromatography
a. Liquid chromatography
b. Gas chromatography
2. What are the immiscible phasesThese are the components of the experiment that don’t get dissolved in the solvent, in the case of this experiment it was the cellulose on the paper.
3.Retention factors
A.32mm/74mm=0.432
B.59mm/74mm=0.797
