Science Fair Project

1868 Words8 Pages

Pearly white teeth are something that many strive for in today’s society due to the beauty that is associated with it. Brand name teeth whitening treatments such as Crest are efficient but many people are hesitant to use chemicals for fear of their health. The goal for my science fair project is to conduct research and experiment to find which natural substances are best for whitening teeth. For the project I used four different mixtures of natural substances: lemon & salt, apple cider vinegar & extra virgin olive oil, fruits & vegetables, and dairy products. From the research and information I collected, I hypothesize that apple cider vinegar & extra virgin olive oil will be the most effect natural substances to whiten teeth due to the enzymes and natural chemicals found in these two substances. After conducting my experiment for approximately a week and a half I discovered that apple cider vinegar & extra virgin olive oil was the best natural substance to whiten teeth. I can concluded that our hypothesis was …show more content…

After research on the topic, I decided to test the natural substances: lemon & salt, apple cider vinegar & extra virgin olive oil, fruits and vegetables, and dairy products. During the research process we hypothesized that apple cider vinegar & extra virgin olive oil will be the most productive in whitening teeth, out of the other three.
I conducted out experiment for a time period of about a week and a half; and found that apple cider vinegar & extra virgin olive oil worked as the best natural substance to whiten teeth. Through the experiment we concluded that my hypothesis was correct. The natural substances, lemon and salt were a close second at whitening teeth. Over all the four mixtures of natural substances I realized that fruits & vegetables were the least effective combination of natural substances in whitening

    The essay “Science: It’s Just not Fair”, by Dave Barry, some truths about science fairs that many students have to participate in are brought out. Barry starts the essay with the beginning of the science fair project process, which is usually put off until the last minute. He sarcastically and ironically describes the process as a student who is rushing to do their project the night before the due date. Barry also includes and comments on the the ironic importance of the hypothesis and conclusion in the science fair process, showing how they usually very vague statements. He also gives examples of his wife’s and his own last-minute science fair projects that they threw together quickly before the due date.

I predict that solution #3 will change the most color after being tested by Benedict’s Lugol’s, and Biuret’s reagent because it has the most protein, sugar, starch in the nutrition facts. To test for a positive reaction, we observe if the solution changes into a specific color depending on which regent is being used. For Biuret’s Reagent, a positive

  • Fast Food Nation Short Summary

    In order to please their customers, companies must have many different flavors. One company offers more than just a butter flavor, instead they offer “fresh creamy butter, cheesy butter, milky butter” and many other butter flavors (Schlosser 23). The reason that these are selling more is because they contain what the FDA considers natural flavors. The reality is that these flavors are created by new enzyme-based processes which give them the same chemical make up as the artificial flavors and taste the same. The author repeats all these flavors because the customer now has access to a wider variety and is more likely to buy the product because of the industry’s abuse of the recreating artificial flavors as “natural flavors.”

  • Chewing Gum Experiment

    However, they are generally produced by hydrogenating sugars, which provides similarities in molecular structure though sugar alcohols do not have the same cyclohexane rings present within their formations, unlike carbohydrates such as glucose and lactose (“What Is Sugar Alcohol,” 2015, para. 4). An inquisitive mind may aspire to divulge what percentage of chewing gum is actually composed of sugar. Students within Serenity Smith’s chemistry class recently discovered how to deduce material composition and was subsequently assigned with this very task. By testing various brands of chewing gum, it is easily conjecturable that the makeup of sugar would account for different percentages among the different gums (Bubble Gum “A Real Sugar High,” n.a., p. 1). To fully comprehend this concept, it is essential to understand the fundamentals of sugar alcohols.

    The experiment conveys how the percent compositions of the sugar in the brand sticks of gum were different, even though the nutritional facts portrayed that the sugar content should have been the same. Based on the data, it is determined that Trident has a lower composition of sugar in the gum, in relation to Orbit. This is shown, as after 5 minutes of chewing the gum, the total mass of Trident dropped by .94 grams whereas the mass of Orbit gum dropped by 1.18 grams. The percent sugar composition in the Trident gum was 50% whereas Orbit had a sugar composition of

    Due to the growing popularity of processed foods and the nation 's abysmal knowledge of them, writer Brian Rohrig argues that food coloring is an important attribute in the foods we eat in his article “Eating with your Eyes: The Chemistry of Food Colorings”. The author uses reasons, evidence, and effective word choice about how what makes a good food coloring, the best sources of natural food coloring and the benefits of synthetic food coloring to strengthen the logic and persuasiveness of his argument. Rohrig 's argument is also furthered when he appeals to the emotions of the reader. By referring the future, it causes the reader to think more in-depth about food coloring and how it may affect the future.
