Make a Science Fair Poster or Display

Make a Science Fair Poster or Display The first step to creating a successful science project display is to read the rules concerning the size and types of materials allowed. Unless you are required to present your project on a single board, I recommend a tri-fold cardboard or heavy poster board display. This is a central piece of cardboard/posterboard with two fold-out wings. The folding aspect not only helps the display support itself, but it is also great protection for the interior of the board during transport. Avoid wooden displays or flimsy poster board. Make sure the display will fit inside any vehicle that is required for transportation. Organization and Neatness Organize your poster using the same sections as are listed in the report. Print each section using a computer, preferably with a laser printer, so that bad weather wont cause the ink to run. Put a title for each section at its top, in letters large enough to be seen from several feet away (very large font size). The focal point of your display should be your purpose and hypothesis. Its great to include photos and bring your project with you  if it is allowed and space permits. Try to arrange your presentation in a logical manner on the board. Feel free to use color to make your presentation stand out. In addition to recommending laser printing, my personal preference is to use a sans serif font because such fonts tend to be easier to read from a distance. As with the report, check spelling, grammar, and punctuation. TitleFor a science fair, you probably want a catchy, clever title. Otherwise, try to make it an accurate description of the project. For example, I could entitle a project, Determining Minimum NaCl Concentration that can be Tasted in Water. Avoid unnecessary words, while covering the essential purpose of the project. Whatever title you come up with, get it critiqued by friends, family, or teachers. If you are using a tri-fold board, the title usually is placed at the top of the middle board.PicturesIf at all possible, include color photographs of your project, samples from the project, tables, and graphs. Photos and objects are visually appealing and interesting.Introduction and PurposeSometimes this section is called Background. Whatever its name, this section introduces the topic of the project, notes any information already available, explains why you are interested in the project, and states the purpose of the project.The Hypothesis or QuestionExplicitly state your hypothesis or question. Materials and MethodsList the materials you used in your project and describe the procedure that you used to perform the project. If you have a photo or diagram of your project, this is a good place to include it.Data and ResultsData and Results are not the same thing. Data refers to the actual numbers or other information you obtained in your project. If you can, present the data in a table or graph. The Results section is where the data is manipulated or the hypothesis is tested. Sometimes this analysis will yield tables, graphs, or charts, too. More commonly, the Results section will explain the significance of the data or will involve a statistical test.ConclusionThe Conclusion focuses on the Hypothesis or Question as it compares to the Data and Results. What was the answer to the question? Was the hypothesis supported (keep in mind a hypothesis cannot be proved, only disproved)? What did you find out from the experiment? Answer these questions first. Then, depending on your answ ers, you may wish to explain ways in which the project might be improved or introduce new questions that have come up as a result of the project. This section is judged not only by what you were able to conclude  but also by your recognition of areas where you could ​not draw valid conclusions based on your data. ReferencesYou may need to cite references or provide a bibliography for your project. In some cases, this is pasted onto the poster. Other science fairs prefer that you simply print it out and have it available, placed below or beside the poster. Be Prepared Most of the time, you will need to accompany your presentation, explain your project, and answer questions. Sometimes the presentations have time limits. Practice what you are going to say, out loud, to a person or at least a mirror. If you can give your presentation to a person, practice having a question and answer session. On the day of the presentation, dress neatly, be polite, and smile! Congratulations on a successful science project!

16 Fascinating Facts About Mosquitoes

16 Fascinating Facts About Mosquitoes Mosquitoes, the insects that are universally hated the world over. These pesky, disease-carrying pests make a living by sucking the blood out of just about anything that moves, including us. But take a moment to look at things from the mosquitos perspective. Mosquitoes are actually interesting  creatures. Mosquitoes Are the Deadliest Animals on Earth Take that, shark week! More deaths are associated with mosquitoes than any other animal on the planet. Mosquitoes may carry any number of deadly diseases, including malaria, dengue fever, yellow fever, Zika, and encephalitis. Mosquitoes also carry heartworm, which can be lethal to your dog. How Long Do Mosquitoes Live? An adult mosquito may live 5–6 months. Few probably make it that long, given our tendency to slap them silly when they land on us. But in the right circumstances, an adult mosquito has quite a long life expectancy, as bugs go. Most adult females live for two to three weeks. For those that winter in your garage, though- look out. Eggs can dry out for eight months and still hatch. Females Bite Humans While Males Feed on Nectar Mosquitoes mean nothing personal when they take your blood. Female mosquitoes need protein for their eggs and must take a blood meal in order to reproduce. Because males dont bear the burden of producing young, theyll avoid you completely and head for the flowers instead. When not trying to produce eggs, females are happy to stick to nectar, too. Some Mosquitoes Avoid Biting Humans Not all mosquito species feed on people. Some mosquitoes specialize on other animals and are no bother to us at all. Culiseta melanura, for example, bites birds almost exclusively and rarely bites humans. Another mosquito species,  Uranotaenia sapphirina, is known to feed on reptiles and amphibians. Mosquitoes Fly Slowly Mosquitoes average a flight speed of 1 to 1.5 miles per hour. If a race were held between all the flying insects, nearly every other contestant would beat the pokey mosquito. Butterflies, locusts, and honeybees would all finish well ahead of the skeeter. A Mosquito's Wings Beat 300–600 Times Per Second This would explain that irritating buzzing sound you hear just before a mosquito lands on you and bites. Mosquitoes Synchronize Their Wing Beats Scientists once thought that only male mosquitoes could hear the wing beats of their potential mates, but recent research on Aedes aegypti mosquitoes proved females listen for lovers, too. When the male and female meet, their buzzing synchronizes to the same speed. Salt Marsh Mosquitoes May Live100 Miles Away Most mosquitoes emerge from their watery breeding ground and stay pretty close to home. But some, like the salt marsh mosquitoes, will fly long distances to find a suitable place to live, with all the nectar and blood they could want to drink. All Mosquitoes Need Water to Breed- but Not Much Just a few inches of water is all it takes for a female to deposit her eggs. Tiny mosquito larvae develop quickly in birdbaths, roof gutters, and old tires dumped in vacant lots. Some species can breed in puddles left after a rainstorm. If you want to keep mosquitoes under control around your home, you need to be vigilant about dumping any standing water every few days. Most Mosquitoes Can Travel Only 2–3 Miles Your mosquitoes are basically your (and your neighbors) problem. Some varieties, like the Asian tiger mosquito, can fly only about 100 yards. Mosquitoes Detect CO2 75 Feet Away Carbon dioxide, which humans and other animals produce, is the key signal to mosquitoes that a potential blood meal is near. Theyve developed a keen sensitivity to CO2 in the air. Once a female senses CO2 in the vicinity, she flies back and forth through the CO2 plume until she locates her victim. Bug Zappers Don't Attract Mosquitoes Bug zappers give off light that attracts gnats, beetles, moths, and the like, but because mosquitoes are attracted to you by CO2, they are not effective at killing mosquitoes. They likely kill more beneficial insects and those eaten by songbirds than mosquitoes. They even take out parasitic wasps, which control other species. How Do You Kill Mosquitoes? Fogger machines that attract mosquitoes with CO2 and then trap them do work, but repellants for your yard and self may be the easiest and most cost-effective way to go. Why Do Mosquitoes Exist? Basically, mosquitoes exist because theyre next to impossible to wipe out. Species dont exist in a vacuum; as long as they can find food and dont have environmental pressure against them, theyll continue. Mosquitoes are millions of years old as a species. In the ecosystem, they do serve as food for other species (birds, frogs, and fish) and as pollinators. The larvae eat detritus in the water, helping to clean it. There are more than 3,000 species of mosquitoes, but only about 200 bite humans. Not Everyone Is Allergic to Mosquito Saliva Mosquito saliva, which lubricates the proboscis to glide into the skin, is responsible for the itching and bump on your skin, but not everyone is allergic to mosquito saliva. Some people even avoid getting bitten, and their sweat is being studied to develop repellents. Mosquitoes Have Benefitted Science The design of their proboscis has inspired scientists to design less-painful hypodermic needles, examine strategies to make needle insertion easier, and create insertion guides to better place tiny electrodes into the brain.

Principles of Management - Essay Example ASDA's values are to keep daily prices low, for which it also has a label for itself which is ASDA Smart Price. They boast that all the products under the ASDA Smart Price are the cheapest price available anywhere. Environment consists of the surroundings within which every organization operates. The world is going through tremendous changes, such changes whose impact is very far-reaching and powerful. And thus, organizations cannot operate in isolation. The environment has made them interdependent with other factors and dependent on other units within the environment. (Rayner, 2005) The external environment is that environment which is outside the boundaries of the organization. But nevertheless, it affects the organization through its activities and happenings. The external environment can be further sub divides into the general environment and the task environment. The general environment is that part which affects the organization indirectly. Whereas, the task environment is that part which affects the organizations workings and productivity in a direct way. The general environment has various dimensions, like that of international, technological, socio-cultural, economic, and legal-political. Various changes in these dimensions are highly likely to affect how the company operates. (Buchanan, 2007) When it comes to recession, a lot of changes have resulted in the above mentioned dimensions. In the international dimension, the financial crisis has hit the whole globe, thus leading to a shortage of funds all around the world. The technological dimension has not been affected much since it has become more of a necessity than a luxury and thus cutting down on technology has not been made much due to recession. The socio-cultural dimension has altered since people are now cutting down on luxury items, holiday trips and other extravaganzas of life that they used to enjoy. Simple living is the talk of the day. The economic dimension is in a very messy position since the financial crisis has strained the economies of almost every country in the world, especially the big giants. And lastly, the legal-political dimension has changed so as to inculcate the financial crisis. Tax laws have changed; labor unions are concerned about getting laid off. Thus, recession has affected almost every dimension of the general environment. (Watson, 2005) The task environment consists of the groups of people with whom the organization is interacting on a regular basis. This includes the customers, the competitors, the suppliers, as well as the labor market. A common mistake is to assume that the labor market is equivalent to the employees who are working at the organization. This is not so. The labor market consists of those people whom the organization can hire, they are the potential employees. Recession has also affected these groups of people. The customers are now choosier about what to buy and want the greatest value for their money. Employees have a fear of getting laid off by the company. And suppliers now have less bargaining power as compared to their clients since clients are cutting down on production

Comparing poems Nothings changed Essay Example for Free

Comparing poems Nothings changed Essay The Poem nothings changed is based on Tatamkhulu Afrika himself who spent many years in South Africa and his autobiographical poem which describes most of what him and others had experienced and his own feelings expressed during the policy of Apartheid, introduced by the government in his country. This forced many popular attractions such as beaches, buses and even towns to be changed to white areas only. For some this meant leaving the country forever all just because of the colour of there skin. The poem itself is set out in six stanzas, each including eight fairly short but important lines. This kind of layout and structure in the poem creates a sense of control, showing how the poet is extremely clear about what he is saying and feeling in his head with no sudden actions leading to rage. Within the pattern of the poem the line lengths do also vary from a whole entire stanza to just two little words. For example: District Six. No board says it is: but my feet know, and my hands, and the skin about my bones, and the soft labouring of my lungs,and the hot, white, inwards turning. This shows how the structure of the strong poem changes in the stanzas, gradually getting bigger sentences as the stanza speaks on, giving a feeling of confidence in the poet proving he knows what he is talking about with all the information gathering. The whole poem is written in the present tense, although always recalling past experience he had the poet is constantly reliving the experience as he writes every word. This makes this poem in particular stand out from what were they like? due to the fact it is easy to identify what is going on. The poet also clearly states how he is feeling and what he is exactly doing as he writes, describing every little detail by putting us in his shoes. The poem overall describes how he returns to the wasteland that was once his home and relives the anger he felt when the area was first destroyed. With him seeing the restaurant Which consists of being expensive, stylish, exclusive with a guard at the gatepost it makes him think about the poverty around it especially the working mans cafi across from it were people live without eating from plates and on a plastic table top. This makes him reflect that despite the changing political situation, there are still huge inequalities between blacks and whites. Even though South Africa is supposed to have changed, he knows the new restaurant is really whites only. He feels that nothing has really changed overall. The deep anger he feels makes him want to destroy the restaurant completely to smash the glass with a stone, or a bomb. Secondly the poem what were they like written by Denise Levertov who wrote poems that opposed American fighting in Vietnam in the 1960s. This particular poem is against the typical American ignorance of the Vietnam war. She published the poem to show her true feelings about what the American army themselves had done to the people and the way of life of Vietnam. The structure of the poem is like an interview, having the interviewer or questioner ask all the questions together and then the speaker answer each question after one another. Altogether there are six questions followed by six very surprising answers. Also at the end of the poem the answers are followed by a rhetorical question who can say? This makes the reader think in there head about the answer and shows the unusual treatment Vietnam received by the American army. In the poem itself she compares two different periods, before and after the war had ended showing the interesting experiences people were put in and what she wants answered for. The tone in the first section of the poem includes a thought on curiosity and full of wonder and also could be considered as being questions which are asked quickly and impatiently as when reading them you want to get to the answers straight away. Also the tone of the questioner may seem to be angry and a state of foolishness and insensitivity, yet still having a sense of sadness because of the loss of such an innocent country and the people who lived there during this hectic time. The questioner themselves represent the uninformed Americans and the response being Denise Levertov giving the impression that the questioner should have known more about Vietnam. The responses to the questions seem rather bitter and brutal to the suffering people as when read seem honest and quickly spoken in your head which is what the poet is trying to get at to show the emotion of which happened during the war itself. Overall both poems include some similar qualities, both being completely true and poets experiencing the lives lived out there. Yet nothings changed is describing the life long change of the country since introducing the law of Apartheid in the 1960s and how the country is still living with it, and overcoming the stress and changes the country had to make to change the lives of black and white people which is something of anger and hatred. This is shown by a personal experience form living in the country and visiting local areas and recording the atmosphere of the place. This anger can also be shown in what were they like although this particular poet may have had experience from Vietnam she was not there to see it and includes in her poem questions referring to the fact she wants answers to what has happened in the past war against America. This shows the poems are different one including life experience on unfair laws made and the other just wanted answers on what she believes what happened in the Vietnam war is completely wrong.

Persepolis by Marjane Satrapi Essay -- Memoir

Growing Up Satrapi It is hard to tell the story of a â€Å"typical† youth and it is hard to write a story that relates to experiences in everyone’s lives, but this is exactly what Marjane Satrapi accomplished in her memoir. Persepolis is the story of a child’s growth from preteen to adult. The specific challenges that Satrapi faces are unique to her situation, but we can ask whether they accurately portray the psychological development that children go through. Do her reactions to situations resemble the reactions that most children have to similar problems? While reading Satrapi’s story, it is necessary to understand that the circumstances she encounters and her reaction to these circumstances parallel how youths around the world react to similar situations. Throughout her memoir, Satrapi uses stepping-stones that all children use and reaches the same stages of development that psychologists believe most children reach. For these reasons, Persepolis is a believable coming of age story. Throughout a child’s life, many factors influence their socialization. In Persepolis, Satrapi demonstrates the three major microsystems1 that influence a child’s socialization; family, education, and community. As a ten year old child, Marjane lives in a typical nuclear family, her community is currently in the midst of a revolution, and her school is teaching her how to look and act like a proper woman. It is important to understand how these three microsystems are crucial in Marjane’s development as a young adolescent. In American society, schools are used to educate children on how to become independent members of society. Children are expected to abide by rules that are established in the classroom, and they are taught to mo... ...Company, 2004. Dopheide, Julie A.

The Goal

Jakeshia Moore Mktg 372 Alidee Nov 28, 11 The Goal: A Process of Ongoing Improvement The Goal by Eliyahu Goldatt is a novel, regarding the management and accounting processes at a manufacturing plant. The book focuses around a perhaps older 30- early 40s something industrial engineer, Alex Rogo. With the description Goldatt gives of Rogo, he personifies the profile of a large number of people involved in business administration (Lui 1997). Alex is married, with two children and his lively-hood is in jeopardy, unless he can figure out exactly how to save his production plant, by understanding â€Å"the goal† of his company. In order for Rogo and the readers to even begin understanding that â€Å"goal†, Eli begins to unravel the novel by introducing the readers to Alex Rogo and apparent problems with his production plant. In the opening of the first chapter these problems meet Mr. Rogo at work, as a confrontation takes place between him and his immediate boss, Division Vice President of their company UniWare, Bill Peach. The dispute takes places over an overdue order number 41427, which happens to be fifty-six days behind schedule. Given this has become the norm for Rogo’s plant, Mr. Peach requires nothing less than for order #41427 to be shipped that day, since the plant is neither profitable nor productive. In fact so many orders, as of late, have been so far behind that it is becoming a major problem for the company and the lively hood of the workers. Therefore, Mr. Peach decides to give Alex three months to turn things at their plant, or he’s prepared to recommend the Bearington plant be shut down. With the amount of time order number 41427 is already late; the pressure is on to get the order out the door and shipped according to Mr. Peach’s specifications. Surprisingly the plant gets the order shipped that night, but not very effectively. All the hands in the plant are working on one order, with forbidden overtime to compensate. Only after dinner with Lou, his controller, does Alex develop a sense of determination to define his mode of constraints. His efficiencies are good, but he can not to put to a finger on what’s causing the problem; and without the Five Steps of Focusing this at first seems impossible. Alex has spent late nights pondering the future of the company. He attempts to identify â€Å"the problem† at his plant, the process he will have to go through to change it, how resistant his plant would be to that change, and how he intends to overcome their resistance. Alex does all of this just in time for Mr. Peach to call a plant managers meeting at the headquarters. On his way to the meeting, Alex learns the problems with efficiency and effectiveness are not only plaguing his plant, but it’s the entire industry. It’s been losing money since Japan entered the manufacturing market and stolen market share from companies in the United States, like their UniWare Division of UniCo. During the meeting with Mr. Peach and the other plant managers, Alex mistakenly comes across a cigar he received from and old friend; a physicist named Jonah, and has an epiphany. Two week prior to the meeting, by pure chance, Alex ran into Jonah and they began to catch up. Alex gave Jonah a run down of his job as plant manager at UniCo, and eagerly described how his firm’s investment in automation (ie. obots) had increased productivity by thirty-six percent. Jonah, in turn questioned Alex about some key identifiers of productivity such as: their ability to decrease inventory, reduce operational expenses, and selling more product. Jonah really asked some in-depth questions to help Alex understand his core problems. Until Jonah predicted their problems with high inventories and not meeting shipping dates, A lex was sure he was simply dealing with some routine problems, not the demise of his entire organizational structure. Jonah explained to Alex that there is only one real â€Å"goal† for any organizations, and anything bringing you closer to achieving that is productive and anything otherwise is unproductive. Productivity, according to Jonah, is defined as accomplishing something in terms of goals. Late for his flight, Jonah uses the Socratic Method to help Alex conclude what â€Å"the goal† of his plant really is. Alex struggles with the questions Jonah ask initially, but eventually discovers and internalizes the concept of the Theory of Constraints. Meanwhile at the meeting, .

Human Computer Interaction Individual Report Essay

We as a group we have been set tasks to evaluate an existing system and capture the required improvements that should be made to the system through comprehensive research using the required methods to improve usability of the system. As a group we are to understand the user and capture its needs through numerous of method for example, questionnaire. I within my group decided to evaluate the system (www.pogo.com) as it was thought to inspect the system thoroughly from which some major errors were confronted. To check if these were to reflect the user of the system and that it was effecting the lack of consistent and comprehensive movement from within the site i considered to evaluate the system using ‘Shneiderman’s 8 Golden Rules’ . The evaluation method constructed errors which were found are to be tested with the users and get feedback via the talk aloud and the questionnaire from which I with my group will be able to test the system and capture the user requirements Content Page Paragraph Name Page Number Summary 1 Methods chosen, why 3 Problems Encountered 3 Feedback from users 4 Achievements from the assessment 4 Conclusion/ Recommendations 5 Bibliography/ references 6 Books 6 Web sites 6 Methods chosen, why The interface that chose to evaluate and redesign, was www.pogo.com as this website was not that appealing to me and I think it needs improvements as it is aimed at a family audience. To evaluate the system www.pogo.com it was required to test the system and check if the system had any major error or were they minor problems, in order for me to do this I decided to evaluate the system using the 8 golden rules of Shneiderman’s. The method was used to evaluate the system as this enabled me to test the colour, resolution, text, layout etc†¦ and I thought this method was very useful to appoint out the usability problem that the system was carry to the users. To carry out the evaluation I was first to understand the method and then continue to explore this with the system (www.pogo.com) . The methods used for capturing user requirements were Observation, Questionnaire and talk aloud. These methods were chosen because they were Easy to explore with the system, Cost Effective and Time Effective. Problems Encountered The major problems encountered during the task tests were to find the appropriate user to tackle these tasks. As the methods used were demanding a wide range of user that fitted in the categories of the novice, intermediate and expert users, it was difficult to address the needs of certain user as all categories were involved and from each users view was taken into consideration. There were novice, intermediate and expert that took the task which was a real heap for me as this would help me redesign the interface to fulfil the usability needs. Feedback from users From asking the users to complete the tasks more knowledge was gained for what users expected within a website, from this I was able to point out the like and dislike. From this I also acknowledge that the users prefer their website to be attractive so it is enjoyable to use and users also like to take minimum amount of steps to complete a particular task. The results which I obtained were very useful for redesigning the website. I found out what different usability needs were and what features users wanted to be remained on the website, and any others which they thought required changing. From this information I chose to do a paper based prototype for my system because it was simple, cheap and provided quick feedback from the user. Achievements from the assessment Having completed the assessment I feel that I would be able to explain the usability of any website/interface and from this I am able to identify usability problems such as psychological problems of the system, as well as being able to evaluate any system in depth. From this assessment I have also knowledge how I would explain various methods of capturing user requirements, stating the advantages and disadvantages of the method. Conclusion/ Recommendations If I was to do the assessment again, I would use Shneiderman’s Eight Golden Rules to identify the usability of the system, as I found them very useful both to understand and apply towards the website. I would also use the ‘Ten Heuristics’ to evaluate the website and I would have a great image of usability in evaluating the system. If given a chance in the future to redesign the system I would choose to do a low fidelity prototype but as well as this I would prefer to redesign the website in a high fidelity prototype provided that I am given extra time than provided in my first attempt. The reason for this would be that the users would see the prototype in a low fidelity and will be given a chance then to test the system via a high fidelity prototype. As I only had five users to complete the set task, I was unable to get different views from users to make changes to the redesign. In the future I would ask more users (maybe 10 different users) to complete at least three different tasks. By doing this, the users would experience more interaction with the system www.pogo.com and would comment more on the results they would achieve from the task, and also whether they were able to complete the task accurately, in a minimum amount of time.

Reasons Why Some Dont Get into Graduate School

Reasons Why Some Don't Get into Graduate School Youve spent years preparing to apply to graduate school: taking the right courses, studying for good grades, and seeking appropriate experiences. Youve taken the time to prepare a solid application: GRE scores, admissions essays, recommendation letters, and transcripts. Yet sometimes it doesnt work out. You dont get in. The most qualified of students can do everything right and still sometimes not get admitted to graduate school. Unfortunately, the quality of your graduate school application isnt the only thing that determines whether you get into graduate school. There are other factors that have nothing to do with you that influence your acceptance. Just as in dating, sometimes Its not you, its me. Really. Sometimes a rejection letter is more about the graduate programs capacity and needs than about the quality of your application. Funding A loss of funding at the institutional, school, or department level can reduce the number of applicants they can support and accept.Fewer funds for Teaching and research assistantships can mean accepting fewer studentsMany students are admitted to work with particular faculty and are supported by faculty members grants. A change in grant funding means that some qualified students will not be admitted.You dont have control over any of these factors, but the availability of funding has a huge impact on the likelihood that you will be admitted to a graduate program. Faculty Availability Whether faculty are available and able to take on students influences the number of students who are accepted in any given year.Faculty are sometimes away on sabbaticals or leaves. Any students who would be accepted to work with them are often out of luck.Sometimes faculty are overloaded and do not have space in their lab for another student. Good applicants are turned away. Space and Resources Some graduate programs require that students have access to laboratory space and specialized equipment. These resources can accommodate only so many students.Other programs include internships and other applied experiences. If there are not enough slots, then well-prepared students do not get admitted to the graduate program. If you are rejected from your preferred graduate program, recognize that the reasons may not lie with you. Often there are factors are beyond your control that influence whether you are accepted to graduate school. That said, keep in mind that rejection is often due to applicant error or, more commonly, the poor fit between the applicants stated interests and the program. Pay attention to your admissions essay to ensure that your interests fit those of the faculty and program.

Why Fossilized Shark Teeth Are Black

Why Fossilized Shark Teeth Are Black Shark teeth are made up of calcium phosphate, which is the mineral apatite. Although shark teeth are sturdier than the cartilage that makes up their skeleton, the teeth still disintegrate over time unless they are fossilized. This is why you rarely find white shark teeth on a beach. Shark teeth are preserved if the tooth is buried, which prevents decomposition by oxygen and bacteria. Shark teeth buried in sediments absorb surrounding minerals, turning them from a normal whitish tooth color to a deeper color, usually black, gray, or tan. The fossilization process takes at least 10,000 years, although some fossil sharks teeth are millions of years old! Fossils are old, but you cant tell the approximate age of a shark tooth simply by its color because the color (black, gray, brown) depends completely on the chemical composition of the sediment that replaced the calcium during the fossilization process. How to  Find Shark Teeth Why would you want to find shark teeth? Some of them are valuable, plus they can be used to make interesting jewelry or to start a collection. Plus, theres a chance youll find a tooth from a predator that lived 10 to 50 million years ago! While its possible to find teeth just about anywhere, your best bet is to search at a beach. I live in Myrtle Beach, so every time I go to the shore I look for teeth. At this beach, most of the teeth are black because of the chemical composition of the sediment offshore. At other beaches, fossilized teeth may be gray or brown or slightly green. Once you find the first tooth, youll know what color to seek. Of course, theres always a chance youll find a white shark tooth, but these are much harder to see against shells and sand. If youve never looked for shark teeth before, start out looking for black pointy objects. If the teeth are black, there will also be some black shell fragments that resemble shark teeth.  How do you know if its a shell or a tooth? Dry off your find and hold it up to the light. Even though a tooth could be millions of years old, it will still look glossy in the light. A shell, on the other hand, will show ripples from its growth and maybe some iridescence. Most shark teeth also maintain some of their structure. Look for a cutting edge along the edge of the blade (flat part) of the tooth, which may still have ridges. Thats a dead giveaway youve scored a shark tooth. A tooth may also have an intact root, which tends to be less shiny than the blade. Teeth come in a variety of shapes. Some are triangular, but others are needle-like. Good places to start are at the waterline, where the waves can help reveal the teeth, or by inspecting or sifting through a pile of shells. Keep in mind, the size of the teeth you can find is usually similar to the size of surrounding debris. While its possible to find a giant Megalodon tooth in the sand, large teeth like this are most often found near similar-sized rocks or shells.
