Motion of the Earth :: physics earth spin

The Earth spins around an axis. The Earth takes (a bit more than) one day to go around once. This axis is pointing off somewhere in space. This axis (mostly) doesn’t move. At the same time, the Earth is orbiting the Sun. It takes (a bit more than) one year to go around once. The plane of the Earth’s orbit (mostly) doesn’t move. The spin axis of the Earth’s daily rotation is not perpendicular to the plane of the Earth’s orbit.It is tilted (approximately) 23.4 degrees. The angle of tilt (mostly) doesn’t change. Earth does not spin perpendicular to the plane it is tilted, the reason earth is tilted is because it got hit by meteoroids and other stuff when the planets first formed. Also it takes about 24 hours for one period of earth rotate. From that we get sunlight, half of our days. We can calculate easily how fast earth is spinning by 2πR(radius of the earth)/24 hours. but that is just speed of the equator of the earth. We have different spinning speed every different latitude. As we could see from above picture every latitude have different speed of spinning per hour. And speed of the earth spinning could effect on such as water reservoirs.We don't feel that because everything else is moving with us and because the motion is very, very smooth. Changes in the Earth's spin are measured in terms of length of days. A faster spin shortens the length of daylight. "Due to the reservoir effect," (Chao). "the day 40 years ago was longer than today by about 8 millionths of a second." More significant, he said, is the fact that the sporadic spacing of water reservoirs has changed the Earth's axis. Since 1940, water impoundment has pushed the axis of rotation about 60 centimeters away from the North Pole toward western Canada, said by Chao Also it effect on the direction of the wind and movement of the clouds. "Stars and planets form as a result of the gravitational collapse of accreting material. Any net translational motion of that initial material is accelerated as its radius of rotation decreases. Once an initial spin was established for the Earth, the same conservation principle says that its angular momentum will continue unless it can be transferred to another object. With no significant frictional forces to allow that to happen, the Earth can continue to spin indefinitely without any further prodding" said by Paul Walorski.

Discover the affects of PH on the enzyme catalase

Catalase- This is an enzyme found in food such as potato and liver. It is used for removing Hydrogen Peroxide from cells. Hydrogen Peroxide is the poisonous by-product of metabolism. It speeds up the decomposition of hydrogen Peroxide into oxygen and water. It is able to do this because the shape of its active site matches the shape of Hydrogen Peroxide molecule. This type of reaction where a molecule is broken down into smaller pieces is an ANABOLIC REACTION. BACKGROUND INFORMATION ON ENZYMES: Enzymes- Enzymes are complex 3-D globular proteins, some of which have other associated molecules. Enzymes are a catalyst which alters the rate of chemical reaction without itself undergoing a permanent change, and therefore can be used over and over again. Enzymes help reactions speed up which would otherwise take place very slowly. While the enzyme molecule is relatively larger than the larger than the substrate molecule it acts upon, only a small part of the enzyme molecule actually comes into contact. This region is called the ACTIVE SITE. The active site of an enzyme is the region that binds the substrate and contributes the amino acid residues that directly participate in the making and breaking of chemical bonds. However, all enzymes operate only on a specific shape and therefore fit only complementary locks, so only substrates of a particular shape will fit the active site of an enzyme. Prediction I predict that as the PH increases the activity of enzyme increases until the optimum PH is reached. Catalase optimum ph is around 6-7.after that the enzyme will be denatured. Hypothesis The enzyme will have an optimum pH of around neutral. Either side of the optimum pH will have relatively high rates of reaction or far away from the optimum pH will have a low rate of reaction. The enzyme catalase is found in many tissues including potato and liver. It is important because it breaks down the hydrogen peroxide formed in metabolism. Hydrogen peroxide is toxic and if it were not broken down it would kill the cells. As it does this, it liberates carbon dioxide that can be collected. CHEMICAL EQUATION: 2H2O2 ——————-> 2H2O + O2 I also hypothesize that the catalase activity will be highest with the sample of potato comparing to the apple. Variables The factors, which will have an affect on the enzyme activity, will be: * Temperature * Concentration of enzymes * pH The variable in which I will be using to investigate the enzyme activity is the temperature. The rest of the variables will be kept constant and only the temperatures will be changed. Apparatus To test how the PH affects the rate of reaction, I will use the following apparatus: * Gas syringe through bung * Potato * Hydrogen Peroxide * Stop Clock * Cork borer * Scalpel * water Beaker-250 cmà ¯Ã‚ ¿Ã‚ ½ * Delivery Tube * Ph 3,5,7,9 * 5 cmà ¯Ã‚ ¿Ã‚ ½ or 10 cmà ¯Ã‚ ¿Ã‚ ½ plastic syringe with end cut off * measuring cylinder * conical flask * White tile * wax * Test tubes * Test tube rack * Safety equipment; goggles, lab coat, gloves Alternative: Use yeast, broad beans or liver, instead of potato and apple. Method 1. Measure out 5cm3 of potato into a conical flask 2. Measure out 10 cm3 of buffer solution into a separate container and mix it with minced potato. 3. Measure out 5cm3 volume of hydrogen peroxide in syringe. 4. Fill a tub with water. 5. Completely immerse a measuring cylinder in the water making sure to release all air bubbles in the cylinder and keep underwater. 6. Position the cylinder upright ensuring the open end remains underwater and clamp securely 7. Add the hydrogen peroxide to the potato and place bung on conical flask whilst starting timer. 8. Run experiment for 5 minutes taking readings every 30 seconds by noting the amount of gas at top of cylinder (at meniscus) 9. Repeat the experiment with different ph. Justification of method: I have chosen to use this method because it is safe, efficient and accurate. I feel that it will help me to obtain reliable results. Risk Assessment * Hydrogen peroxide is a dangerous substance. It can cause serious injury to the eyes and skin. It is therefore necessary that goggles be used for eye protection. In addition, eye irrigation equipment should be readily available in case of an emergency. * The working area must be clean, tidy and dry. Make sure there is no obstacle in the working area so that you can easily move around as. This allows you to perform the experiment safely and unimpeded care should be taken to ensure that liquid is not spilled onto the floor to cause slippage. Result table Time(s) Oxygen gas collected (cm3) Ph 3 ph 5 ph7 ph9 30 1.5 1.5 0.5 1.5 60 1.5 3.0 1.5 2.0 90 1.5 5.0 2.0 2.0 120 1.5 7.0 5.65 2.0 150 1.5 8.3 10.3 2.0 180 1.5 9.0 14.35 2.0 210 1.5 10.0 17.35 2.0 240 1.5 11.1 20.15 2.0 270 1.5 13.6 24.15 2.0 300 1.5 14.0 31.15 2.0 These results clarify that the optimum ph for catalase is 7 which supports my prediction. At the lowest ph 3, less oxygen was released, measuring a slower rate of reaction. My background information explains this. The enzyme don't work as it is neared extreme PHS. This is because its shape would have been change slightly; means the active site may not fit into the substrate any more. Further investigation: If this investigation were to be done again, I would take all results myself and use my own interpretation, thus gaining more reliable results. I will know how much potato to measure out for each experiment and also I will make sure that the other variables are kept constant. I have taken the same amount of each, keeping them constant. This would give me clearer results to aid me in my understanding as to how ph can affect the activity of catalase.

Difference Between Independent and Dependent Variables

The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured  in a scientific experiment. The dependent variable is dependent on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded. Independent and Dependent Variable Example For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light  is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source)  would be the dependent variable. How to Tell the Variables Apart The independent and dependent variables may be viewed in terms of cause and effect. If the independent variable is changed, then an effect is seen in the dependent variable. Remember, the values of both variables may change in an experiment and are recorded. The difference is that the value of the independent variable is controlled by the experimenter, while the value of the dependent variable only changes in response to the independent variable. Remembering Variables With DRYMIX When results are plotted in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis. The DRY MIX acronym can help keep the variables straight: D is the dependent variableR is the responding variableY is the axis on which the dependent or responding variable is graphed (the vertical axis) M is the manipulated variable or the one that is changed in an experimentI is the independent variableX is the axis on which the independent or manipulated variable is graphed (the horizontal axis) Independent vs Dependent Variable Key Takeaways The independent and dependent variables are the two key variables in a science experiment.The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable.The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected. Sources Carlson, Robert. A concrete introduction to real analysis. CRC Press, 2006. p.183.Dodge, Y.

Is Beowulf a Hero - 2129 Words

Is Beowulf a hero? It is vital when approaching the question of whether or not Beowulf can be viewed as a hero to attempt to understand the concept of a ‘hero. Joseph Campbell, the American theorist, studied mythological characters and texts in great detail and developed the concept of the monomyth (or Heros Journey) which he suggested all heroes undertook: A hero ventures forth from the world of common day into a region of supernatural wonder: fabulous forces are there encountered and a decisive victory is won: the hero comes back from this mysterious adventure with the power to bestow boons on his fellow men. If we are to take this statement as being accurate it is fair to say that at least in so far as what actually occurs in†¦show more content†¦Shortly before his contest with Grendels mother we are told he is ‘indifferent to death a point which is exemplified when prior to the fight he sets out his wishes to Hrothgar for what should be done should he perish. He is not arrogant enough to assume victory is assured and yet he is also courageous enough to not fear the possibility of defeat. In Seamus Heaneys translation of Beowulf we constantly see him referring to the great Geat as a hero. For instance ‘the hero arose and ‘heros helmet are but two of the references made. Although it is a hugely contentious issue, if we are to assume that Heaney is attempting, if only on the point of calling Beowulf a hero within the actual translated text, to give as direct a translation as is possible then it would seem apparent that the original author was making no secret of the fact he wanted him to be seen in this way too. There have been many criticisms of the character of Beowulf that highlight certain traits which could point away from the notion of him being a hero. One such idea is that he fought the monsters chiefly for personal reasons: ‘Beowulf steadily shifts from a primarily defensive role to an aggressive one, motivated to varying degrees in each of his battles by thoughts of glory, vengeance and treasure It is particularly the stance that Beowulf was motivated by thoughts of glory that I believe endangers the belief that he was a hero.Show MoreRelatedBeowulf Is A Hero Of Beowulf1017 Words   |  5 PagesIn the movie and book Beowulf, Beowulf represents a hero.

Conclusion Introduction In the modern times of today, the world revolves around technology. With astonishing breakthroughs in science and technology every single day, the world is always changing, always adapting to the next big thing. To be more specific, the world revolves around engineering, genetic and mechanical. There are medicinal breakthroughs in genetic engineering all the time, cures for diseases, much needed vaccinations for new viruses, genetically improving plants for better produce, and overall improving different organisms so they will be better suited for life. On the other hand, in mechanical engineering, breakthroughs happen more often: better fuel efficient cars and cars that don’t run on gas at all, faster processing computers, new smart phones, and so many other gadgets that make life so much easier. Both of these fields are very important to society. The world literally wouldn’t be anywhere close to being the same without one or both of these fields, but which one is better? They each have equal importance in the world, but which is a better field to go into? Which field is easier to get into? Which will provide better benefits for its employees and for the world as a whole? After vigorous research the answer will be known. Mechanical Engineering: Description of career Mechanical engineers plan and design tools, engines, machines, and other mechanical systems that produce, transmit, or use power. These designs range from gasoline engines to rockets to kitchen food mixers. Their work varies by industry, employers, and function. They may work in design, instrumentation, testing, robotics, which is whole different field, transportation, or bioengineering (Careers in Focus, pg. 83). Mechanical engineering is the broadest of all engineering disciplines and fields; it extends across many interdependent specialties. Mechanical engineers may work in productions operations, maintenance, or technical sales and finance. There also many engineering administrators or managers (Engineering Careers, pg. 5). There are approximately 221,000 mechanical engineers employed in the United States (buzzle. com). Mechanical Engineering: History The earliest people who might have been called mechanical engineers were the ones who built things, large or small, safely and efficiently. Mechanical engineering has existed for thousands of years. Although on a simpler scale, pyramid building in ancient Egyp t, for example, required extensive knowledge of engineering principles, large blocks of two and even three ton stone were transported and positioned perfectly to make the pyramids the world knows today (Mech. Eng. New Book of Knowledge pg. 224). The Ancient Greeks and Romans were also great builders, and also very influential on western civilizations architectural style. Unlike the Egyptians, they developed and made use of elaborate mechanical devices, like water pumps and power generating treadmills that were used for lifting and moving heavy objects. The Greeks even invented a steam engine, but back then they viewed it as a toy and not useful (Careers in Focus pg. 84). The term engineer was coined in the 14th century. It applied only to those who designed equipment for war. Their achievements were so important that the strength of a country’s military became heavily dependent on their inventions. Engineers who worked on civilian projects became simply known as civil engineers. Later, engineers who worked on machinery and generating power were called mechanical engineers (Engineering Careers pg. 98). The modern field of mechanical engineering sprouted during the Renaissance. During this time engineers focused their energies on developing more efficient ways of doing ordinary tasks like pumping water. Water wheels and windmills were common energy producers (buzzle. om). Leonardo da Vinci was a true innovative engineer. He tried and nearly succeeded in creating a helicopter, submarine, and his famous flying machine. One of the most significant inventions of the Renaissance was the clock (Encyclopedia of Careers pg. 221). Despite these developments, it wasn’t until the Industrial Revolution that modern day mechanical engineering came to life. The steam engine was introduced in 1712 by Thomas Newcomen. Over half a century later, James Watt modified the steam engine to be power large industrial machines. In 1876 Nicolaus Otto developed the internal combustion engine which became one of the most significant and important inventions of the century. The American Society of Mechanical Engineers was formed by 1880 (Careers in Focus pg. 85). Mechanical engineering expanded rapidly in the 20th century. Mass production systems allowed large quantities of standardized goods to be made at a low cost, and mechanical engineers played a large role in the design of these systems. In the second half of the 20th century computers came into play heavily. Mechanical engineers now design mechanical systems on the computer, and they are used to test, monitor, and analyze mechanical systems and factory production, a trend that is evident during modern times (Goodwin, Peter pg. 51). Mechanical Engineering: The Job On average a mechanical engineer makes anywhere from $48,426 to $100,000+, and they deserve every penny of it. The work of a mechanical engineer begins with research and development. Depending on what company you work for, you could be asked to develop a more fuel efficient car engine or many other things. Then research is done to further knowledge in whatever you’re trying to build before you actually design it (buzzle. com). Information gained from research is then taking to be analyzed and used to make a commercially useful product. The engineer would be responsible for specifying every single detail of the machine or mechanical system. Since the late 1900’s, mechanical engineers have increasingly used computers in the design process. After the product has been designed and a prototype has been developed, the product is analyzed by engineers. Design and testing engineers continue to work together until the product meets the necessary criteria (Careers in Focus pg. You read "Engineering Research Paper" in category "Essay examples" 85). Once the final design is set, it is the job of the engineer to come up with most time and cost efficient way of making the product without sacrificing quality. The amount of factory floor space, the type of manufacturing equipment and machinery, and the cost of labor and materials has to be considered. Engineers select the necessary equipment and machines and oversee their arrangement and safe operation. Other engineer specialists, like chemical, electrical, and industrial engineers may help (Mech. Engineering New Book of Knowledge pg. 226). Mechanical engineers also work in marketing, sales, and administration. In a small company an engineer may need to perform most if not all of the above tasks on their own. The working conditions of mechanical engineers vary. Most work indoors in offices, research laboratories, or production departments of factories and shops (Careers in Focus pg. 89). Depending on the job, an engineer may spend a significant amount of time on a noisy factory floor, at a construction sight, or at another field operation. Mechanical engineers originally designed systems on drafting boards and making the traditional blueprints, but since the introductions of sophisticated software programs, design is more and more done on computers (Goodwin, Peter pg. 55). For the most part, engineering is a cooperative effort. An engineer may have specific duties and require independent work; each project is usually the job of an entire engineering team, a team that can include other engineers, engineering technicians, and engineering technologist (Mech. Engineering New Book of Knowledge pg. 228). Mechanical engineers generally have a standard 40 hour workweek. However their work hours heavily depend on the deadlines for projects. They may work long hours to make a deadline, or show up for second and third shifts to check production at a factory or a construction project (Engineering Careers pg. 101). Mechanical engineering can be a very satisfying occupation. Engineers often get the pleasure of seeing their designs or modifications built and operating. On the other hand it can be very frustrating when a project is stalled, full of errors, or even just abandoned. Mechanical Engineering: Education Before anyone can become a mechanical engineer, like any other career, they need an education. Starting high school, one must take courses in geometry, trigonometry, and calculus. Communication skills are important for mechanical engineers because they interact with a variety of co-workers and vendors and are often required to make and/or/ present reports, so English and speech classes are also helpful. Also because computers are now so important to engineering, computer science courses are also recommended (educationportal. com). A bachelor’s degree in mechanical engineering is usually the minimum educational requirement for entering the field. A master’s degree or even a Ph. D. may be necessary for obtaining some positions, like those in research, teaching, and administration (educationportal. com). In the United States, there are more than 200 colleges and universities where engineering programs have been approved by the Accreditation Board for Engineering and Technology. Most of these institutions offer programs in mechanical engineering. Although it varies from school to school, most require a solid background in mathematics and science (Career in Focus pg. 87). In a four year undergraduate program, students start with studying calculus, physics, and chemistry. At some schools, a five or six year program combines classroom study with practical experience working for an engineering firm. Students usually end up working for the firm after college. A graduate degree is a prerequisite for becoming a university professor or researcher. It may also lead to a higher level job within an engineering department or firm (Encyclopedia of Careers pg. 223). Genetic Engineering: Description of Career Genetic engineering is the direct manipulation of an organism’s genome, or DNA structure, using biotechnology. Genetic engineering alters the DNA of the chosen organism, by either altering the DNA directly or inserting a different DNA strand inserted that was made outside the host. If genetic material from another species is added to the host, the resulting organism is called transgenic (Gen. Engineering New Book of Knowledge pg. 2). Genetic engineers use their research and experiments to find cures for disease, breed better animals and plants, and to one day map the human genome which would then give us the knowledge of a potential disease free human race. Genetic Engineering: History Long before the principles of genetics were known people began to domesticate wild animals and plants and selected those that could be use d for food or for doing work. This selective breeding was an early kind of genetic engineering, a deliberate effort to develop strains of organisms that would benefit human beings. There is even a bible story revolved around genetic engineering in which Jacob strategically mated his black sheep with his employer Labans white sheep, creating spotted and streaked sheep (Gen. Engineering New Book of Knowledge pg. 82). In time, many new strains of plants and animals were developed. Among these were new strains of cattle, horses, dogs, cats, wheat, rice, and corn. An example would be the different kinds of horses, a sleek fast racehorse and strong larger workhorses. Breeding animals this way became very popular and useful to the US (Encyclopedia of Careers and Vocational Guidance pg. 51). During the 1900’s, genetic engineering became a much more accurate science and study. Scientist learned to breed pure strains of plants and animals. These purebred strains are genetically constant. This means that all of the offspring will be exactly like their parents for every generation. The purebred strains did not always show desirable qualities. But when different pure breds were mated with one another, some of the offspring showed more desirable qualities and unusual vigor. The offspring produced are called hybrids. They have genes from two or more different strains (Dhillon, Sukhraj pg. 34) At first, scientist depended on natural mutations to produce the kinds of genes that could be used in developing new strains, but nature took too long. Later they learned to cause mutations by exposing organisms to radiation such as X-rays. Offspring who actually displayed useful mutations were developed into new valuable strains. Offspring that did not display useful mutations were kept for further testing, set free, or terminated depending on the mutation (McCuen, Gary pg. 30). Millions of lives have been saved by one product of genetic engineering that was developed in this way. In 1928 a Scottish scientist discovered that penicilium molds make a bacteria fighting substance know to us as penicillin. It was first used during World War II to treat infections in soldiers’ wounds. The molds however did not produce enough penicillin to meet the demand. In a lab, some strains of penicilium were X-rayed to cause mutations. In time, high-yielding strains of the mold were developed and large amounts of penicillin were produced (The Ethics of Genetic Engineering pg. 6). As scientist learned more about genetics, they learned how to remove, purify, and study the genes of simple organisms. Bacteria were of particular interest because of their ability to make enzymes that can cut through strands of DNA at specific places. With these enzymes, bacteria can attack viruses that invade their cells by cutting the DNA from the viruses into harmless fragments (Gen. Engin eering New Book of Knowledge pg. 84). Genetic Engineering: Potential Risks and Dangers These enzymes also have made possible a dramatic new kind of genetic engineering called gene splicing. Gene splicing is actually portrayed accurately in fiction movies. The freakish monsters can actually be created. Using this method, scientist can take a gene from one organism and splice into another organism’s genetic material. Since the bases of DNA are the same for most organisms, pieces of DNA from quite different species can be spliced together to create incredible creatures. Almost any kind of plant or animal DNA can be inserted into the DNA of bacteria, and vice versa. Even synthetic DNA can be spliced into a cell’s genetic material. This is DNA made entirely in the laboratory (Career in Focus pg. 69). Some people believe that gene splicing could be used to create new kinds of dangerous new organisms, either accidently or on purpose. Government and private research organizations follow guidelines for gene splicing. Some kinds of experiments can be carried out only in laboratories that have special safety features. So far, gene splicing has not caused any out breaks of serious illnesses or environmental disasters, as critics feared. However, the possibility exists that gene splicing will not always work as planned. As a result, some people have called for stricter regulations of this technology (Levine, Harry pg. 52). Besides gene splicing, biological and biochemical warfare is the biggest threat of genetic engineering. Biological warfare is the use of biological toxins or infectious agents such as bacteria, viruses, and fungi with intent to kill or incapacitate humans, animals or plants as an act of war. Diseases have been genetically engineered to kill its host and be completely i mmune to any vaccines. Although biological warfare was outlawed in 1972, the United States has biological defense and offense programs in case that level of war would ever be needed (McCuen, Gary pg. 119). Conclusion In conclusion, mechanical and genetic engineering are both very important to society. Mechanical engineers are the backbone to society. Mechanical engineers design, build, and test new technology to help better the lives of humans. They not only give us new toys to play with, but advances in technology keep us safe with fast reacting systems for police, unbelievably accurate weather tracking systems to warn people of severe weather, and advancements in the United States military to keep the country the land of the free. While on the other hand genetic engineering has saved the human ace countless times. The scientific engineers have developed vaccines and immunizations to all kinds of disease most people have never even heard of. Although they are both very important fields, mechanical engineering outweighs genetic engineering. As a career mechanical engineering provides better opportunities and is more enjoyable as a career. Although genetic engineering has important breakthroughs, those breakthroughs don’t happen very often, every couple decades or so, while breakthroughs in mechanical engineering happen by the months. Mechanical engineers make people’s lives easier. That could mean making a car that runs on less gas and someone doesn’t have to pay as much gas, making a high tech phone, or putting GPS satellite tracking in your phone so you will never lose it. Also and more importantly, mechanical engineers don’t such a high risks as genetic engineers.

Equality and Diversity free essay sample

Identify the current legislation and codes of practice relevant to the promotion of equality and valuing of diversity. There are several current pieces of legislation relating to equality and diversity, including †¢ UN Convention on the Rights of the Child (see†¦Ã¢â‚¬ ¦) †¢ Every Child Matters †¢ Children’s Act 1989 †¢ Children’s Act 2004 †¢ Human Rights Act 1998 The most recent act is the Equality Act 2010. Previous to this, equality legislation in this country was somewhat fragmented. The purpose of the new act was to harmonise and strengthen all previous equality legislation (eg The Equal Pay Act 1970, Sex Discrimination Act 1975, Race Relations Act 1976, Disability Discrimination Act 1995). It sought to promote equality, by clarifying the definitions of direct and indirect discrimination, victimisation and harassment. It identified nine groups of people to be protected from discrimination, referred to as ‘protected characteristics’. These are: †¢ Age †¢ Disability (both physical and mental) †¢ Gender reassignment †¢ Marriage and civil partnership Pregnancy and maternity (pregnant women, women on maternity leave, and breast feeding women) †¢ Race (not just colour, but also nationality, ethnic or national origin) †¢ Religion and belief (including those with lack of belief ie Atheists) †¢ Sex †¢ Sexual orientation It states that there is a public duty to eliminate harassment (â€Å"unwanted conduct which has the purpose or effect of violating someone’s dignity, or which is hostile, degrading, humiliating or offensive†), discrimination and victimisation â€Å"treating someone unfavourably because they have taken or ight take action under the Equality Act, or supporting someone else to do this†). By taking any of families or, friends or even my own beliefs in to school is unfair on the children I am here to support. They could be made to feel that if because of their background or who they are meaner they cannot aspire to be what they want to be so will not reach to achieve their full potential. As with another example my father-in-law is sexist and believes that a womans place is in the home cooking, cleaning and looking after the children and if I was to take that to school with me I could treat the girls differently dismissing their work and only encouraging the boys, giving the girls the false idea of they are not good enough. For example: Both men and women teachers have low expectations of girls intellectual skills since it is thought that girls are inherently less intelligent than boys (www. Right-to-education. Org)The support I give the children should be fair and equal in order for every child to feel safe, an equal part of society and that they are worthwhile. Each child should feel that their opinions count and that they have a voice that should be heard, they should not feel excluded or feel that they can exclude any other person because their race, religion, background, sex as this can affect their self-esteem, their confidence and will in turn effect their learning s proved by Jane Elliot in the brown eyed-blue eyed experiment (The Eye of The Storm) in 1968 where the children wearing the collar (to show they were the lesser pupils) took longer than they did the day before when they werent wearing the collars in a card pack reading practice. The children had low expectations of themselves and their body language changed (they looked shrunken into themselves). To challenge discriminatory behavior there are many different methods that could be used for different types of discrimination for example if I heard a child Ewing racist, calling each other names such as pack I would go to them straight away and say: Excuse me children I heard what you Just said why are you calling each other names ¦ We dont use language like that at school how do you think that has made Ron tell. At do you think would rig NT thing to say to him. Let is my responsibility and I am legally obliged as a T. A to challenge any kind of discriminatory behavior. If there were problems in the playground at lunchtime when the boys were excluding the girls from football at lunchtime I could make changes to the laggardly so I would have an assembly to explain to the children why they would be having a week plan for the use of the football area and it would be as follows: Monday: Girls only netball. Tuesday:Boys only football. Wednesday: Mixed netball. Thursday: Mixed football. Friday: Something completely different, a team building game to get them working together. After this I would find from them what has worked well and what hasnt. Elf children in year were sending offensive emails I would use the computer to suite to get them to research the consequences of their actions which they will then present to the class or in assembly. This would give them an insight into how such behavior can affect the victims, they would also be made to apologies to the person or people they were harassing. I In conclusion by not administrating we give every child the same opportunities and support them equally, every child has the same right to an education no matter their background, race, religion, sex or disability. Children will have confidence in who they are and will be more productive in the classroom. I I Excellent and thoughtful answer. This also covers 4. 2. 5 Just add this at the top of the page.
