The purpose of the project was to determine the effect of coffee, tea, or soda on the tooth enamel. The project was to determine which drink causes more damage to the tooth enamel. The hypotheses of the project were that coffee would stain your teeth. The eggs that was left in the tea or soda I thought would be less stain than the coffee. The egg that was left in the coffee will look more stain than the tea or soda, but then it turns out the egg in the Coca-Cola was stained more than the egg left in the coffee or tea. The first part of the procedure in this project was to boil nine eggs. After that I place three eggs each in three separate containers with one cup each of tea, coffee, or Coca-Cola. The egg was monitored for three days while
The purpose of this experiment was to identify which brand of mint gum holds its flavor the longest. The four brands I chose were Orbit, Trident, Ice Breakers, and Wrigley's Doublemint My hypothesis was that Trident brand would last the longest and Wrigley's Doublemint would last the shortest. I did not use any people in my test. I chewed the same amount of gum at a time and the gum was all the same flavor, mint. All the gum was bought at the same time from the same store. I chewed the four brands of gums between periods of time. When chewing, I timed myself with a stopwatch. When I believed the gum ran out of flavor, I stopped the timmer and recorded the time. My hypothesis was incorrect. Instead of Trident, Orbit lasted the longest. However
The experiment consisted of manually brushing tiles for two minutes. However, brushing for exactly two minutes every time is unfeasible, even with the use of a timer. The time of washing after the tile was brushed was not a control and varied. Another potential disruption to the data could include the amount of force used on each tile. For each trial, Crest was brushed first which may potentially mean more force went into brushing that tile, causing it to be the whitest. An additional factor that may have affected the results is the amount of toothpaste. The amount of toothpaste used to brush each tile was most likely different every time which may have contributed to the results. More trials could have been useful for this project as five trials probably was not enough to ensure accurate
Per the hypothesis, most of the results in the lab are in accordance with the expected results. It was expected that the subjects drinking caffeine, diet caffeine free soda, and 16 ml/Kg of water would have a higher rate of production than the control group drinking 7.5 ml/Kg of water due to less water being reabsorbed. Results showed an increase in rate of production, most notably in subjects drinking diet caffeine free soda but seemed to decrease towards the end. For the rest of the subjects, the data shows a gradual rise over time with every subject (besides caffeine free) having a higher rate of production than the control group. The subjects drinking caffeine free soda were the only ones to record a lower rate of production than the control group. This could be due to an increase in glucose reabsorption causing water to follow back into the blood stream. The lack of caffeine does not hinder ADH secretion, which will cause an increased permeability to water in the collecting
The very first step of my experiment is to get all the equipments and materials I need. What I need for this experiment are six kinds of berries I chose, enough yeasts, x-ray machine and materials for comet assay. The first step of my experiment is to give berries to the yeast. I will give berries to yeast by blending the berries using the blender, and then whiz it, so I can add the juice from the berries to the yeast. While I am doing my experiment I will have to decide how much juice I add to yeast. Then after adding the juice I will x-ray the yeast with the x-ray machine, with the help of an adult. After x-raying the yeast I will use the comet assay technique to see if it damages it or no. My final step is to collect the data.
Going into details of the article, I realized that the necessary information needed to evaluate the experimental procedures were not included. However, when conducting an experiment, the independent and dependent variable are to be studied before giving a final conclusion.
Have you ever wondered, “What are my drinks doing to my teeth?” Well, you will find out through our experiment. This means taking teeth and putting each one in a liquid and observing them over a period of time. What we did was we took six teeth and put them in six different sugary liquids. The effects will be big. This won’t happen to you if you don’t brush your teeth.
My experiment is testing one of the five senses of my dog, Blaze. I am testing for taste. In this experiment the question I am going to answer is, Which of three flavors of treats will my dog prefer? The treats are made by the same company, Beggin’ Strips from Nestlé Purina PetCare Division, but they are different flavors. The flavors used will be Hickory Smoked Bacon, Bacon & Cheese, and Bacon & Peanut Butter. My hypothesis for this experiment is, Of the three flavors my dog will prefer the Bacon & Cheese flavor the best. I chose this topic for my experiment because I have a major interest in animals and I am hoping to get a degree in some form of veterinarian services, such as zoology.
Caffeine, commonly found in coffee and many other beverages, and containing certain chemicals compounds leading to the constant necessity of fidgeting, jitters, sleepless hours, and health hazards as though being tormented by a hobgoblin with the irresistible sweet aroma and multiple flavors trapping you into a path, not being able to truly quit as desired or consequences attached, but is it the world’s most used legal drug addiction or something enjoyable, you decide? “The delicious chemical in caffeine is 1,3,7-trimethylxanthine”(Linn). “Caffeine is made by pressuring cooking beans with CO2 to produce the drug in powder form”(Linn). “In caffeine the consumption breakdown in Coffee is 54%, Tea it’s 43%, Food and misc it’s 3% and used as a common mood-altering drug in the world, most popular way of ingesting is through coffee”(Linn). The issue with drinking coffee is due to the fact that caffeine can cause some troubling effects like insomnia activity in the brain that prevents sleep, constant need to urinate leading to dehydration due to the lack of fluids in the body, and diarrhea causing the food right out because it accelerates the digestion in the stomach. The consumption of too much caffeine can cause damage in human health also causing an overdose leading to death. The impact in society is through how much caffeine Americans consume daily, and the effects it causes in human health and sleep patterns. Throughout the years past caffeine consumption in America has increased jarasicaly, about 90% in some form daily. “On average Americans have been known to consume 280 mg of caffeine per day or 2-3 cups of coffee”(Linn). Strangely enough, caffeine is still contained and found in decaffei...
Soda is such a bad aspect to your daily health because of many reasons. Soda does not contain any essential nutrients needed for a healthy diet, just sugar. Soda is full of empty calories, it does not contain any vitamins, minerals, antioxidants, or fiber. It adds nothing to your diet except excessive amounts of added sugar and unnecessary calories.
For my 6th grade science fair project I chose to find out which drink is better for you and which drink improves performance more, Gatorade or Powerade. I chose this topic because I am an athlete, and it would be nice to know which drink is healthier, along with which drink replenishes better. My group members and myself formed hypotheses to answer these questions. I hypothesized Powerade would be healthier because it has vitamins B-3, B-6, and B-12, while I thought Gatorade would improve performance more because it has more electrolytes, sodium, and potassium. We tested our hypotheses by doing research online and performing experiments.
The independent variable of our assignment was the amount of sugar added to water. The dependent variable was the days that the flowers stayed alive. The levels of the independent variable were no sugar, five milliliters of sugar, ten milliliters of sugar, and fifteen milliliters of sugar. The control group of the science experiment was the vase without any sugar added to the water. The main constants of our project were the amount of water in each vase, the temperature of water in each vase, and the type of flower used. There were three repeated trials of the
high amounts of sugar and acid consumption teeth can rot, stain, and erosion. Drinking soda is bad for one’s dental health.
Every day before sleeping, I record the exact time and collect them to show the effectiveness of certain methods. This experiment could be divided into 3 steps:
Overall I think I carried out the experiment in a precise way and I took my time trying to make all my measurements as accurate as possible so that my data is reliable. Next time I will do more tests instead of just 3 so I have more results and so I could get a more accurate average. I will also do the experiment with more fruit juices to see if there are other fruits with a higher content of vitamin C. I will do an experiment to see if there is a difference in Vitamin C levels between fresh juice and store bought juice. I can also test different brands of juice to see if they have different levels of vitamin C.
