This science fair project checks to see which one of the three, tea, coke or coffee stains the teeth the most. The hypothesis is that coke will stain the teeth the most is because of all the sugars in the cola. This project is interesting because a lot of things can stain the teeth; even parents tell to brush and floss because a lot of things can stain the teeth. The achievement in the project is to see which product can stain the teeth the most. How do teeth get discolored? Easy this is called extrinsic, this is when the outside of the tooth (the enamel) is stained, things like coffee, wine, cola, even smoking can stain the teeth. The different parts of the tooth are the enamel, dentin, gingiva, pulp, cementum, periodontal ligament, root, …show more content…
The dentin is one of the tooth layers, it is under the enamel, if there is an infection, the infection will try and get the dentin because is has a series of tubes that lead directly to the dental pulp. The gingiva is just basically the gums. The pulp is the soft tissue inside of the center of the tooth, the nerve tissues and blood vessels are there, if infection were to get to the pulp there will be pain. The cementum is a calcified substance that protects the roots of the teeth, the cementum also helps attach the tooth to the alveolar bone. The periodontal ligament is connective tissue that helps connect the tooth to the alveolar bone where the tooth sits. The root is part of the tooth that is connected with bone, it makes up two-thirds of the teeth and holds the tooth in …show more content…

Science Fair Project: The Effects Of Erosion

...My first post I explained what my science fair project is. I am showing the effects of erosion and what makes erosion move quickly and how to slow it down. I have started working on the project and putting it together. I have the materials all together and some parts started. I asked for some of my friends help to drink some soda out of 2-liter bottles so that I can use that for my project. I am now waiting on those bottles and my friends are almost done with their soda. I am hoping to gather all of the bottles by tomorrow. Once I have the bottles I will be able to put in some plants that I got along with set up the display to hold the bottles. I have gotten the trifold and have been working on what will be going on that. I do need to go over...

Science Fair Project

...My Science Fair Project During my seventh grade year in the spring of 2013, I developed my science fair project about the correlations in sportsmanship between middle school boys that participate in sports and their parents. The judges at my school science fair conveyed to me that my project was not a science project. I did not complain about this, and my teacher still allowed me to attend the annual Greater New Orleans Science and Engineering Fair (GNOSEF) hosted by Tulane University. I placed first in that competition and ended up winning the Behavioral Science division at the Louisiana Science and Engineering Fair (LSEF), which took place at the campus of Louisiana State University. I learned through this experience that my maintaining...

Airplane Science Fair Project

...Airplane Flight Science Fair Project Research Have you ever wondered how an airplane flies? That happens because of four different factors. This paper explains airplane wings, lift, and stalls during flight. Since the science far experiment is what forces affect the airplane wings during a stall. Using different articles from online resources, flight, lift, and stalls were explained in numerous ways. Thrust, Drag, Weight and Lift are the four factors that allow an airplane to take flight. Dunbar (2003) explains these in depth. Thrust is a force that moves an aircraft in the direction of the motion. It is created with a propeller, jet engine, or rocket. Air is pulled in and then pushed out in an opposite direction. One example is a household fan. Drag is the force that acts opposite to the direction of motion. It tends to slow an object. Drag is caused by friction and differences in air...

Science Experiment

...Abstract There is strong interest in "going green," including using products that cause less environmental damage when they are disposed of. In this environmental sciences project, you will compare the toxicity of "green" and conventional liquid detergents using worms as test organisms. Objective The objective of this environmental sciences project is to determine if green detergents are safer for the environment than conventional detergents. Introduction Reduce, reuse, recycle. These are typically known as the three R's of the environment. Every year, Americans throw away billions of containers and other packaging materials that end up in landfills. Reducing the amount of waste you produce is one way to help the environment. Another way to help the environment is to recycle. Many of the things we use every day, like paper bags, soda cans, and milk cartons, are made out of materials that can be recycled. Recycled items are put through a process that makes it possible to create new products out of the materials that come from the old ones. Reusing is another way to help protect the environment. The idea is simple: instead of throwing things away, try to find ways to use them again. The use of grey water to irrigate plants is an example. Grey water is the water produced by showering, cleaning clothes, washing dishes, etc. It does not include human waste (that is called black water, and is not safe to use for irrigation). Clearly, if grey water is to be used for growing...

Your problem statement and hypothesis are extremely easy to write if you have determined your independent and dependent variables. Lets begin with the problem statement. This statement is ALWAYS written as a question. The question should always start with either which or how. The one you choose will depend on your independent and dependent variable. The form should be Which or How will the independent variable affect the dependent variable. Picture Look at the examples to the left. These questions are problem statements based on the independent and dependent variables which were previously decided. How will .... or Which amount .... are excellent ways of starting your problem statement. As you can see, both of these problem statements fit the format described above. How or which independent will affect the dependent. Okay, now it is time for you to write your problem statement for your science fair project. 1. What is your problem statement? Picture Our next step is to write a hypothesis. The hypothesis is very much like the problem statement except it is the answer to your question.

Plastic

...“Genius,” Thomas Edison famously said, “is 1 percent inspiration and 99 percent perspiration.” He would have found a kindred spirit in Elif Bilgin, 16, of Istanbul, Turkey, winner of the 2013 $50,000 Science in Action award, part of the third annual Google Science Fair. The award honors a project that can make a practical difference by addressing an environmental, health or resources challenge; it should be innovative, easy to put into action and reproducible in other communities. Bilgin spent two years toiling away on her project to develop a bioplastic from discarded banana peels, enduring 10 failed trials of plastics that weren’t strong enough or that decayed rapidly. She was undaunted. As she put it in her project description: “Even Thomas Edison said, ‘I have not failed. I have just found 10,000 ways that won’t work.’” Finally, in her last two trials, she made plastics with the features she sought, and it did not decay. We admire her persistence, which will be help her to take advantage of another aspect of her Science in Action prize—a year’s worth of mentoring to help further her work. I like to think, too, that Edison, who used to stop by the Scientific American offices in New York City to demonstrate his latest inventions, would have approved. The ingredients to make Bilgin’s plastic are relatively benign. As she wrote in her entry materials, “it is possible to say that one could do it at home.” In her research, she learned that starch and cellulose are used elsewhere...

...Many science experiments can be explained using mathematics. As you write your research paper, you'll want to make sure that you include as much relevant math as you understand. If a simple equation describes aspects of your science fair project, include it. Writing the Research Paper Note Taking As you read the information in your bibliography, you'll want to take notes. Some teachers recommend taking notes on note cards. Each card contains the source at the top, with key points listed or quoted underneath. Others prefer typing notes directly into a word processor. No matter how you take notes, be sure to keep track of the sources for all your key facts. How to Organize Your Research Paper The best way to speed your writing is to do a little planning. Before starting to write, think about the best order to discuss the major sections of your report. Generally, you will want to begin with your science fair project question so that the reader will know the purpose of your paper. What should come next? Ask yourself what information the reader needs to learn first in order to understand the rest of the paper. A typical organization might look like this: Your science fair project question or topic Definitions of all important words, concepts, and equations that describe your experiment The history of similar experiments Answers to your background research questions When and How to Footnote or Reference Sources When you write your research paper you might want...

Describe the Fraud Risk Factors That Are Indicated in the Dialogue

...Assignment Final Project Complete the Final Project Science Meets Real Life Whether you think of yourself as an up and coming scientist or not, you use science every day. You will explore how you apply different aspects of science in your daily life in a two part project. In 1,500-words (minimum), discuss the following: PART I: SCIENTIFIC METHOD Each and every day, we are faced with having to make split-second decisions, and the need to solve random problems that we encounter. To reach those decisions and work those problems out you are subconsciously using the scientific method. Apply the five steps of the Scientific Method to two situations that could occur in your everyday life. Use the scientific method in the first scenario provided below to solve the problem at hand. Please come up with a second detailed scenario on your own and follow the same steps in the scientific method to find a resolution. Scenario 1: You arrive home late at night. You walk up to the front door, unlock it, and reach in to turn on the light switch located just inside the front door. The light does not come on! Now what? Scenario 2: Develop your own detailed problem/observation and apply the scientific method to solve. PART II: WHY I CANNOT LIVE WITH/WITHOUT SCIENCE As you have seen throughout this course, science is intricately interwoven with our lives: in the food we eat, in the clothes we wear, in the computers we use for this course, science has had a hand in them all.
