Big Question * How do different colas break down the enamel on our teeth? * Which Cola is the most corrosive to our teeth?
Hypothesis and Explanation * If an egg shell is put in cola, then the egg shell will become discolored and thin. It will be broken down because of the sugars, carbonation, and acid. The cola will have a similareffect on human teeth as it does on the egg shells. My Interesting Facts * Soda discolors our teeth. * Soda wears away the enamel on your teeth and makes them weak. * The Coca Cola left a film in the jar. * Phosphoric acid is also found in milk, meats, and grains. * Phosphoric acid has very little effect on our teeth. * The saliva in our mouth helps neutralize the acid in the soda, therefore acid has littleeffect on our teeth.
Materials Needed and Instructions for the Experiment * Materials: * 5 egg shells. Wash and cleaned of the egg whites and yokes * 5 mason jars with lids 5 cola brands. * Coca Cola * Dr. Pepper * Pepsi * Diet Coke * Big K Cola * Masking tape to label each jar. * Log book.

This is how I conducted the experiment. I began by pouring one can of each of the sodas into each of the mason jars. Then I had my mom crack five eggsand wash out the egg whites and yokes. I then placed each of the shells into each of the five colas. I put a lid on each of the jars to help keep out any extra germs in the air. I then daily opened the jars and carefully and observed each of the egg shells to look for changes in their colors and to see if any holes or cracks had formed from being in the soda. I observed the shells for one week and daily entered the results into a log book.
Constant Variable * Adding the same amount of soda to each Mason jar. * One egg shell…...

The Effect F of Different Type of Sugar on Yeast

...The Effect of Different Types of Sugar on Respiration in Yeast INTRODUCTION: Yeast is living bacteria that uses in baking to make dough rise through the process of fermentation. For fermentation to occur yeast requires fuel in the form of sugar. The yeast reaction varies depending upon the type of sugar use. AIM: To determine the effect of different types of sugar (Maltose, Lactose and Glucose) have on the respiration rate of yeast. HYPOTHESIS If the type of sugar changed (Maltose, Lactose and Glucose), the amount of carbon dioxide created (bubbles) will then increase because sugar needed for respiration to occur. But, I think Maltose + Yeast will produce more bubbles than other two types of sugar because maltose is the largest sugar in all types of sugar which I am going to do on. Glucose will come into a second place and the least will be Lactose. VARIABLES * INDEPENDENT VARIABLE The independent is type of sugar. I will change it by putting different types of sugar into the water which the yeast would be placed in. * DEPENTDENT VARIABLE The dependent is the amount of bubbles collected from the over a certain amount of time. Rate = CO2/Time * CONTROL VARIABLE 1. Amount of yeast(5 grams) 2. Temperature (50C) 3. Amount of time (1 minute) 4. Amount of sugar (100ml) 5. Concentration (5%) MATERIALS: -Yeast (5 grams) -Sugar (Maltose, Lactose and Glucose 100ml each) -Hot water (50C) -Water bath -Beaker (2) -Delivery......

The Effects of Sugar on the Body

...What that Sugar Rush Really Does When I started to read this article, I was literally blown away by the statistics and studies that they had to back up their findings. A large amount of sugar can actually damage the brain, causing you to stop producing memories, and stunts your ability to learn new things. My first question to this was why does it do this? Well the article kept on explaining to me! Sugar slows the creation of a specific chemical in the brain, and this slowly can eventually stop the production, forcing you to head into a permanent stupor. The creation of this chemical is crucial in the continual development in the brain, and in some cases can harm your current memories. Continuing to read that I began wondering if this could stop people with sugar from learning new things, and remembering certain things, like what they can and can’t eat, what pills they need to take when, and how to properly use a new item. Could it be that the consistent diet of sugar through the years could be a cause of Alzheimer’s, their memories deteriorating because they no longer produce that chemical, or have stunted it to a point that it doesn’t produce enough to keep up with new things. A fine example is an older man or woman with an iPod, or smart phone. These could be causes and reasons, but what is the effect. My sugar intake has dropped considerably since reading this article, and it’s something that I don’t believe will help him in the long run besides teasing and......

...Sugar has long been an essential crop of the Caribbean countries and the news of reform has left the islands scrambling to maintain a viable economy. In order to understand how the islands economies became so dependent on sugar, it must be made clear how sugar became so important, the extent of the Caribbean's dependency on preferential pricing and how the preferences have been reformed. The sugar industry has been a part of the Caribbean since shortly after being discovered and colonized by people of the western world. Its importance can be seen through significant historical changes such as slavery, indentured servitude and finally through independence. The sugar industry creates a significant amount of jobs for the uneducated residents of the Caribbean. According to McDonald (2003) it was estimated in two thousand and three that the industry employed approximately one hundred and twenty-five thousand workers in both direct and indirect employment that otherwise may be unemployed. It served as a tourist attraction and was a major ingredient in the production of Molasses and Rum, both of which generated significant export revenues. Most importantly, sugar exported to the member countries of the European Union generated significant revenues. The European Union (EU) sugar program as it was original implemented in nineteen sixty-eight, served to facilitate competitiveness by compensating intuitional price cuts for sugar with direct income payments. The program consisted of a......

...Subject Terms: *NONNUTRITIVE sweeteners *ASPARTAME *SUGAR substitutes *DEGENERATION (Pathology) *FOOD additives *CARCINOGENICITY RISK factors Author-Supplied Keywords: Artifi cial sweetener aspartame sugar substitute Abstract: Sugar is an inseparable part of the food we consume. But too much sugar is not ideal for our teeth and waistline. There have been some controversial suggestions that excessive sugar may play an important role in certain degenerative diseases. So artificial sweeteners or artificially sweetened products continue to attract consumers. A sugar substitute (artificial sweetener) is a food additive that duplicates the effect of sugar in taste, but usually has less food energy. Besides its benefits, animal studies have convincingly proven that artificial sweeteners cause weight gain, brain tumors, bladder cancer and many other health hazards. Some kind of health related side effects including carcinogenicity are also noted in humans. A large number of studies have been carried out on these substances with conclusions ranging from "safe under all conditions" to "unsafe at any dose". Scientists are divided in their views on the issue of artificial sweetener safety. In scientific as well as in lay publications, supporting studies are often widely referenced while the opposing results are de-emphasized or dismissed. So this review aims to explore the health controversy over perceived benefits of sugar substitutes. [ABSTRACT FROM AUTHOR] Copyright of......

Sugar Reflection

...Malcolm Warner Human Nutrition 3534 Reflection on Sugar 2-17-2014 After watching the assigned videos about sugar I was surprised at the effects that sugar has on the human body and the amount of sugar in many of our processed foods. Many Americans do not pay attention to the serving sizes on the nutrition labels which leads to consuming a massive amount of sugar per day. The facts provided in the documentaries can help people have a better understanding of their sugar consumption and maintain good health. One of the facts that can really help is four grams of sugar equals in teaspoon, men should have about nine teaspoons of sugar per day while women should have around six. As our sugar consumption has grows, so does our bodies. Our risk of obesity, diabetes, and heart disease increases because of the excess amount of sugar in our diets. In one of the documentaries, it specified that a lot of the research about sugar and the evidence provided comes from animal trials which made me question some of the evidence. In another documentary it was explained that sugar is made up of two molecules, glucose and fructose; glucose helps fuel our muscles and our brain while the fructose (which is also in our fruits) is separated and goes to the liver. Too much fructose can liver fat and can start a downstream of metabolic diseases. I don’t necessarily agree with calling sugar “poisonous” and “toxic”. Too much of anything can be bad for you. Drinking an excess of water can be......

.... At 5:30 am the slaves would be sent to the fields with their breakfast. A register would be called and if a slave was absent he would be beaten. Their breakfast at 8:00, consisted of Boiled Yam, Eddoes and Okra which were all seasoned with Salt and Pepper. Work on the sugar Plantation now started, this is where the majority of the Slaves worked. It continued till 12:00 and was a very tiring time. The sugar cane can range from a height of 4 feet to 12 feet or more. Knives were used to cut the stems of the cane and then were at the end of the day, carried to a sugar mill. Here a different set of workers would squeeze the sugar cane to get the precious juice that is used to create sugar. This was a very important job so the smallest mistakes would be punished severely. From 12:00 to 2:00 pm the slaves were allowed to leave their work and have dinner. These often consisted of meaty dishes, as they contain lots of protein which is needed to use muscle. .From 2:00 to 6:00 the slaves had to continue with their work. This was often the time when problems would occur. Many weak slaves would faint in the evenings from extreme heat, and overworking. If this was to happen they would be whipped. At 6:00 the slaves were allowed to return to their huts. After eating bread and butter, or some other light dinner at their hut, they would either be sent to bed, or in the summer forced to work in the boiling house. 3. When the African Slaves were enslaved, they sang slave songs.......

Sugar talk about “What factors really determine the price of sugar in the USA?” based on the Financial Times article “Commodities: A sweet deal”. I divided the presentation in 3 parts. Firstly, I give a short introduction. Secondly, I speak about the determining factors and lastly I give a short summarise about the topic. [Click] 2. Slide: Ok, let’s start with the frame conditions of this topic. Sugar was once a luxury product and the demand for sweets is in our genes. Today, you can get sugar everywhere. [Click] The sugar market is one of the world’s strongest protected and supported market for agricultural products. [Click] The USA is the fifth-largest sugar producer in the world [Click] and the U.S. sugar policy used quotas and restricted imports to balance supply and demand. [Click] The purpose of these restrictions [Click] is the increase of the sugar price in the U.S. market. [Click] The question is “What really influences the sugar price in the USA?” We will see on the next slides. [Click] 3. Slide: On this slide we see on the left side the Price-Quantity-Diagram with the red supply curve and the blue demand curve, [Click] which is extensively inelastic. [Click] That’s means the percentage change in the price is higher than the percentage change in the quantity. A good example of an inelastic demand is the U.S. sugar-market, which is very price sensitive. Ok, let’s look at the supply curve. [Click] If the sugar supply rises, the supply curve shifts to the right side.......

Sugar Love

...Bottom of the Drink They had to go. The Coke machine, the snack machine, the deep fryer. Hoisted and dragged through the halls and out to the curb, they sat with other trash beneath gray, forlorn skies behind Kirkpatrick Elementary, one of a handful of primary schools in Clarksdale, Mississippi. That was seven years ago, when administrators first recognized the magnitude of the problem. Clarksdale, a storied delta town that gave us the golden age of the Delta blues, its cotton fields and flatlands rolling to the river, its Victorian mansions still beautiful, is at the center of a colossal American health crisis. High rates of obesity, diabetes, high blood pressure, heart disease: the legacy, some experts say, of sugar, a crop that brought the ancestors of most Clarksdale residents to this hemisphere in chains. “We knew we had to do something,” Kirkpatrick principal SuzAnne Walton told me. Walton, Clarksdale born and bred, was leading me through the school, discussing ways the faculty is trying to help students—baked instead of fried, fruit instead of candy—most of whom have two meals a day in the lunchroom. She was wearing scrubs—standard Monday dress for teachers, to reinforce the school’s commitment to health and wellness. The student body is 91 percent African American, 7 percent white, “and three Latinos”—the remaining 2 percent. “These kids eat what they’re given, and too often it’s the sweetest, cheapest foods: cakes, creams, candy. It had to change. It was about......

No Sugar

...Stage dramas are created to engage viewers and convey the themes and ideas of the playwright. Stage dramas rely largely on spoken language. Through spoken language characters are created and refined. Davis’ language choices have developed the characters in a way that portrays the characters to be exaggerated colonial stereotypes. Characters are the most vital element of a stage drama; they create the link between the audience and the drama. It is through Jack Davis’ writing that we are led to feel particular ways about most of the characters. No sugar is a play that makes an impact. Jack Davis has chosen not to construct realistic characters, but instead characters that fit into and even sometimes challenge the stereotypes placed on Aboriginal people. Although some characters are exaggerated stereotypes there are also many that aren’t. Every character is constructed in a different way, through dialogue and action. No sugar focuses on the hardships faced by an - albeit stereotypical of the 1930’s - Aboriginal family during the continued colonisation of Australia. Gran is the matriarchal figure of the family; she is the one that tries to ensure the continuation of the Nyoongah culture. She is characterised as strong and often stubborn. Her stubborn attitude throughout the play represents, in some ways, Aboriginal stereotypes. The way that Davis has constructed her creates a bond between her and the audience; the audience becomes attached to her. Through Davis’ choice, Gran’s...

...How Sugar is Made - the History It is thought that cane sugar was first used by man in Polynesia from where it spread to India. In 510 BC the Emperor Darius of what was then Persia invaded India where he found "the reed which gives honey without bees". The secret of cane sugar, as with many other of man's discoveries, was kept a closely guarded secret whilst the finished product was exported for a rich profit. It was the major expansion of the Arab peoples in the seventh century AD that led to a breaking of the secret. When they invaded Persia in 642 AD they found sugar cane being grown and learnt how sugar was made. As their expansion continued they established sugar production in other lands that they conquered including North Africa and Spain. Sugar was only discovered by western Europeans as a result of the Crusades in the 11th Century AD. Crusaders returning home talked of this "new spice" and how pleasant it was. The first sugar was recorded in England in 1099. The subsequent centuries saw a major expansion of western European trade with the East, including the importation of sugar. It is recorded, for instance, that sugar was available in London at "two shillings a pound" in 1319 AD. This equates to about US$100 per kilo at today's prices so it was very much a luxury. In the 15th century AD, European sugar was refined in Venice, confirmation that even then when quantities were small, it was difficult to transport sugar as a food grade product....

Sugar Addiction

...Dopaminergic Pathways’ Role in Addiction: Sugar and Drugs of Abuse Researchers are hesitant to claim sugar to be addictive, however, many studies have been performed showing how sugar has the ability to produce addictive symptoms similar to those of addictive drugs (1). The Diagnostic and Statistical Manual of Mental Disorders (2004) does not define addiction, but rather, has criteria for substance dependence. The first two criteria relate to the “physiological dependence” of drugs of abuse- tolerance: a need for markedly increased amounts of the substance to achieve intoxication or desired effect, and withdrawal: the removal of the drug of choice and its subsequent feelings of anxiety and depression. Often the same (or a closely related) substance is taken to relieve or avoid these symptoms. Sugar consumption has increased because it is ubiquitous- it’s everywhere and in everything. Popular literature claims sugar to be addictive, and mounting scientific evidence is substantiating this concept (2). Research has shown that addiction emerges in the part of the brain known as the Mesolimbic pathway, referred to as the “Reward Center”, which is one part of the dopaminergic pathway (3). This brain system, which reinforces natural behaviors such as sex and feeding, has adapted to synthetic reinforcement (4). Drugs of abuse activate neurons in the ventral tegmental area (VTA). Neurons originating in the VTA project axons into multiple areas of the limbic system......
