The Importance of Photosynthesis and Respiration free essay sample

The Importance of Photosynthesis and Respiration Explain how photosynthesis and respiration are linked in order to provide you with energy from the food you eat: Photosynthesis is the process in which certain life forms are able to use sunlight to create energy. This energy is created by making carbohydrates from carbon dioxide and water in the presence of chlorophyll. Plants release large amounts of oxygen into the atmosphere as they produce much more than needed during the photosynthesis process. Aerobic respiration is an important process in life as we know it. This process further breaks down molecules and sugars using oxygen. During this process adenosine triphosphate (ATP) is created, used to store and transfer energy to cells throughout the body. (Aerobic respiration, 2010) Photosynthesis and aerobic respiration are both needed for each other to be able to perform their primary functions. One without the other would not work properly. Between both of these processes we receive three main sources; water, carbon dioxide and oxygen. We will write a custom essay sample on The Importance of Photosynthesis and Respiration or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Plants and animals require all three of these in order to live. Carbon dioxide and oxygen are a lot like a circle. Animals need oxygen to live and emit carbon dioxide, while plants need carbon dioxide to produce carbohydrates and omit oxygen, thus completing the circle. (Photosynthesis, 2005) During the photosynthesis stage a plant produces oxygen that aerobic respiration will use in order to break molecules, during this process electrons are released creating energy and a substance called adenosine triphosphate (ATP) is created. Through ATP, complex molecules are broken down into simple ones, allowing them to be used appropriately. (Photosynthesis, 2005) In the absence of oxygen some cells and organisms can use glycolysis coupled to fermentation to produce energy from the sugar created by photosynthesis: Fermentation allows for the production of energy without oxygen using organic compounds. Fermentation produces ATP with organic compounds like carbohydrates as the electron acceptor instead of oxygen, although less than cellular respiration. Yeast and muscle cells are capable of both cellular respiration and fermentation to harvest energy. When yeast cells are in a non-oxygen placement, the cells are forced to ferment. This is partially what it means when brewers ferment there beer. Our bodies use cellular respiration, to produce ATP, as our primary source of energy during normal activity. Although when we exert large amounts of energy all at once like running sprints would do, the normal cellular respiration would be unable to keep up with the required amount of oxygen to create ATP, therefore fermentation begins to assist making ATP. Cells use enzymes as biological catalysts to increase or accelerate the rate of reactions, such as those in photosynthesis or glycolysis. This allows reactions to occur under conditions that sustain life: An enzyme is simply a catalyst; also something extra that’s only purpose is to speed a process up that would otherwise take a very long time. Our bodies have copious amounts of these enzymes whose only purpose is to speed up needed reactions and bonds between separate chemicals throughout the body. This bonding process is completed through what is known as enzyme substrate interactions. (Enzyme, 2005) An enzyme-substrate is most easily explained as being an extremely specific key whole in which only a specific enzyme has access to, allowing that enzyme to enter the key whole and pushing to molecules into one. An enzyme-substrate complex substrate undergoes a chemical reaction forming a new product. The substrate still has the ability to break away from the enzyme at this point allowing it the ability to form with a different substrate. An enzyme product is simply a solution. The eventual mating of two chemicals to bond together forms a new enzyme product. Enzyme activity is regulated a couple of different ways, one is known as allosteric inhibition and the other is known as competitive inhibition. Competitive inhibitors bind with the active site forcing the substrate to compete with it, hence the title competitive inhibition. Allosteric inhibition is when an ion bonds to something physically on the enzyme, no on the site, changing the shape of the enzyme. (Enzyme, 2005)? References Aerobic respiration. (2010).

The society of the Aztec and Maya held religion to the utmost highest priority. Aztec and Mayan religious practices were unique and sometimes barbaric. From daily rituals to elaborate ceremonies dedicated to the worship of deities the Aztec and Maya were ensconced in their religion. Aztec and Mayan religious zeal indirectly contributed to their demise. The Aztecs had a number of gods that they worshipped. Many gods had different powers of nature. Some were said to control the actions of a man (Spinden 229). Tezcatlipoca was was said to be a magic and an omniscient god, most likely the chief of the active gods. Aztecs favored the god of war Huitzilopochtli though. Tlaloc was important to farmers for he was the god of rain. Many a sacrifice was made to that god especially in that hot, dry climate they lived in. Ehecatl was the god of wind. Aztecs even had a god for each major city. There were two gods that were, in a sense, imported from another culture. That meant that the Aztecs adopted these gods when they took over a certain tribe or Indian nation. Quetzalcoatl was the most important and had the largest following and history. Xipe was another adopted god worshipped then that is still worshipped by Central Americans today (Spinden ). ...

How does stock price and dividends reflect the value of the firm Term Paper

How does stock price and dividends reflect the value of the firm - Term Paper Example For example, if a corporation issues 100 shares in total, each share provides 1% ownership to the shareholder in the company. Share prices can increase or decrease based on the market conditions and the performances of the company. Corporations often keep certain percentage of its annual profits for future expansion of the company and pay certain percentage of the profits to its shareholders. The annual profit paid to the shareholders by the company is often referred as dividends. The amount of dividend supplied to the shareholders in a particular year depends on the profit achieved by the company in that particular year. In other words, when the company gets more profits, the shareholders get more dividends and vice versa. This paper analyses the importance of stock price and dividends with respect to the value of the firm. â€Å"A company's worth - its total value - is its market capitalization, and it is represented by the company's stock price. Market cap is equal to the stock p rice multiplied by the number of shares outstanding† (What is a company's worth, and who determines its stock price?, 2011). When the company grows or performs well, its share prices will increase whereas when the company underperforms, its share prices will decreases. When a company shows signs of growth, more demand will be created in the share market for its shares. Share purchasers often offer higher prices to the shares of growing companies and the shareholders who sell their share or stake in a growing company may get higher prices in the share market. â€Å"A company’s value for many investors is its ability to generate a satisfactory return over a long holding period. A number of things including financial strength, market dominance, growth potential, and so on, determines that value† (Little, 2011). For example, recently, the share value of many companies dropped drastically because of global financial crisis; however the share value of many other compan ies did not undergo many fluctuations as a result of the recent crisis. The companies which performed better in share market even in the crisis situations are generally perceived as better companies and the investors may invest more heavily in those shares. The share prices of better performing companies may not dip drastically even in unfavorable market conditions. In short, share price of a company is directly proportional to the growth of the company; when the company grows, the share prices will increase and when the company underperforms, share prices will decrease. Since dividend is a portion of annual profit made by a company, no company would be able to pay dividends to the shareholders when it underperforms. At the same time, it is not necessary that a company which is able to pay higher dividends is better than some other companies which are paying fewer dividends or no dividends at all. The value of the company can be better judged based on its operations or activities. O nly by generating more cash than it needs to finance its operating plan, should a company pay a dividend. Thus, for a company like Google with attractive growth opportunities, dividends are basically irrelevant to estimate its value. For mature companies, late in their life-cycle, paying dividends is a way to ensure management does not waste funds on silly projects, or build empires. Further, when a company is relatively mature, and it establishes a well-communicated dividend program, it attracts a particular investor

Instructions for Writing Global Warming - Essay Example Whether we are right or wrong on this score, I still think that it is necessary to conserve the balance of nature in order to keep our earth healthy, thus ensuring that future generations of humans as well as other living beings benefit and thrive as we have done for so many generations. For hundreds of thousands of years, the concentration of greenhouse gases mainly consisting of carbon dioxide and the average global temperature have fluctuated causing the various ice ages. However, for the last several thousands of years a balance in the carbon dioxide emitted and that absorbed by nature has resulted in fairly stable temperatures that have allowed human civilization to develop and thrive. The amount of carbon dioxide in the atmosphere has increased by more than a third since the industrial revolution. Historically such great changes have taken place slowly over thousands of years. This clearly points to increase in human emissions. Industrialization and its hunger for power and speed have led to drastic changes in human lifestyles during the last century. This I believe is the main cause for increasing temperatures, and the sooner we do something about it the better. I believe that if we are able to take measures to reduce the amount of our own carbon emissions, w e can help restore nature’s balance. Governments can help fund research into eco friendly modes of transport and green buildings as well as reward those who comply with these eco friendly measures. If a mode of transport becomes more affordable or is made more desirable by other means, there will be more people lining up for it. Incentives given to industries that conserve energy, improve energy efficiency or use cleaner sources of energy would be effective in reducing emissions. Professor Andrew Hoffman of the University of Michigan calls energy efficiency â€Å"low hanging fruit† while reporting that many companies have found â€Å"easily identifiable solutions for lowering

Long Way Gone Study Guide Essay Example for Free

Long Way Gone Study Guide Essay 1.What does Ishmael say the war is about? Ishmael says nothing about the causes of the war, or what each side was fighting for, or of the overall political and social conditions in Sierra Leone that caused the war. This was a deliberate strategy on the part of Beah, the author. He wanted to present the war through the eyes of a child. As a boy of twelve, when the war first affected him, he had no interest in politics. He had no reason to be interested—his main interest, understandably for a boy of his age, was in singing and dancing to rap music and hanging out with his friends. When the war comes to him, it is for him a battle for personal survival, not a political cause. He is also fueled by feelings of revenge—instilled into him by his army officers—against the rebels because they killed his family. Once again, these are personal feelings not political beliefs. For the reader, then, transported to a land he or she knows nothing about (for the American reader, that is), the war seems not only almost unimaginably brutal but also meaningless. It consists of one side mindlessly killing the other, and vice versa, in skirmishes in small villages. Ishmael does report Lieutenant Jabati’s speeches to his men, in which he says they are defending their country (â€Å"We kill them [the rebels] for the good and betterment of this country† [p. 123]), but such appeals to patriotism are not what inspire Ishmael. Ishmael’s ignorance of politics is again stressed when he is in Freetown during his rehabilitation and sees a convoy of cars and military vans. He is told that the new president, Tejan Kabbah, who had won an election eight months earlier is passing by. â€Å"I had never heard of this man,† Ishmael writes pointedly. This confirms the tenor of the book as a whole: Ishmael is a boy caught up in a war he knows nothing about for a cause he does not care about. 2.Why was the war fought and what course did it take? During the 1980s Sierra Leone was a one-party state governed by the All-People’s Congress (APC) party. However, this period was marked by extensive government corruption and abuse of power. Although Sierra Leone is rich in natural resources it became one of the poorest countries in the world because of mismanagement. The civil war in neighboring Liberia helped to create conditions for war in Sierra Leone because a Liberian war leader reportedly sponsored the rebel group called the Revolutionary United Front (RUF) as a way of destabilizing Sierra Leone, which at the time was a base for a United Nations peacekeeping force. The war broke out in 1991 in villages in eastern Sierra Leone that were near the Liberian border. The aim of the RUF was to seize and control the diamond sector, and in 1991 it took control of the diamond mines in the Kono district. (It is the mining area around Ishmael’s home town of Mogbwemo that the rebels seize in 1993.) In 1992 a military coup took place that established the National Provisional Ruling Council, replacing the civilian government. However, the new military government was powerless to prevent the RUF from controlling much of the country. It was the years immediately after this, from 1993 to January 1996, that Ishmael was a soldier. The war continued after Ishmael was rescued from it, as he himself found out when he went to stay with his uncle in Freetown after his rehabilitation. There had been an election in April 1996, and a civilian government had taken power, but in May 1997 there was another military coup, and the new military government known as the Armed Forces Revolutionary Council (AFRC) invited the RUF to participate in it. The following year, when Beah was safely in the United States, the military government was ousted and the civilian government restored. But this did not stop the violence as the AFRC and its RUF allies fought to regain power. Fighting returned to Freetown in 1999, before a peace accord was signed in July 1999. But this did not last, and the war dragged on, finally ending in January 2002, with the civilian government in charge. According to the CIA’s World Factbook, the civil war resulted in tens of thousands of deaths and the displacement of more than two million people—about one-third of the population of Sierra Leone. 3.What is the situation in Sierra Leone today? According to the CIA’s World Factbook, Sierra Leone is gradually returning to a fully democratic government following the ravages of the civil war. There was a general election in 2007 that led to one civilian government being peacefully replaced by another. The nation has also tried to come to terms with the recent past. In 2002 the government set up a Special Court to try those responsible for war crimes during the civil war. It also set up a Truth and Reconciliation Commission. The Special Court indicted many of those held responsible for the atrocities. Some died before they could be tried, but in June 2007, the Special Court found three men guilty of war crimes, including not only murder, terrorism, and enslavement but also the act of conscripting or enlisting children under fifteen into the armed forces. As refugees from the war are slowly returning from neighboring countries, the Sierra Leone government is trying to create jobs and end political corruption. Revenues from diamond mining have increased significantly since the end of the war. Diamonds account for about half of Sierra Leone’s exports. However, Sierra Leone, with a population estimated in 2009 as 5,132,138, remains an extremely poor country with wide disparities in how wealth is distributed. According to the World Factbook, â€Å"The fate of the economy depends upon the maintenance of domestic peace and the continued receipt of substantial aid from abroad.† 4.How widespread is the use of child soldiers? It would be comforting to think that the forced conscription of children into the armed forces during the war in Sierra Leone was an aberration, not something that can happen again in the modern world. However, that is not the case. Even in the twenty-first century, the use of child soldiers is common in armed conflicts around the world. According to Human Rights watch, an international nongovernmental organization, as of 2007, there were an estimated 200,000 to 300,000 children fighting in various wars. According to a Global Report published in 2008 by the Coalition to Stop the Use of Child Soldiers, at the end of 2007 children were used as soldiers in seventeen armed conflicts around the globe. The coalition noted that this was down from twenty-seven conflicts in 2004, but the downturn was more because the conflicts had ended than because child soldiers were no longer being recruited. The Global Report identified the following countries where children were recruited for paramilitaries, militias, civilian defense forces or armed groups linked to or supported by governments: Chad, Colombia, Democratic Republic of the Congo, India, Iran, Ivory Coast, Libya, Myanmar, Peru, Philippines, Sri Lanka, Sudan, and Uganda. The most flagrant offender, according to the Global Report, is Myanmar, where the government uses thousands of children in its battle against rebel groups. In Uganda, tens of thousands of children have been forced into joining armies over a period of nearly twenty-five years. In some of these countries, including Uganda, girls as well as boys have been forced to become soldiers. There have in recent years been concerted international efforts to end the use of child soldiers. Sierra Leone, which has tried and convicted men responsible for recruiting child soldiers, has become a leader in this issue. The use of child soldiers has now been prohibited by international law. The Optional Protocol to the Convention on the Rights of the Child on the involvement of children in armed conflict has been ratified by 120 states. The UN Security Council has adopted resolutions calling for the establishment of a monitoring mechanism on children and armed conflict. However, these and other prohibitions are no guarantee that when new conflicts break out, child soldiers will not be recruited. 5.Is Beah’s story factually accurate? A Long Way Gone achieved popular and critical success, but questions have been raised by some regarding the factual accuracy of a number of events Beah recounts in the book. Beah writes that his village was attacked in January 1993 and after that he became a refugee from the war. Critics claim that there are school records showing that Beah was in school later than this date, and that the village was attacked in 1995, not 1993. This would mean that Beah would actually have been recruited at the age of fifteen, not thirteen as he writes in the book. This would have meant that he was only a child soldier for a few months, rather than over two years. Some critics point to the structure of the book to confirm this. They point out that most of the book deals with Beah’s wanderings as a refugee and the months he spent in rehabilitation. Only two chapters (13 and 14) cover his actual experiences as a soldier (although he does present more incidents from his military service at various points in flashbacks). Questions have also been raised about the account Beah gives of the fight between the former boy soldiers at the rehabilitation home, in which several boys were killed. There are no independent reports of such a fight ever taking place. Some believe that Beah used others’ experiences as his own and that he embellished his tale. They point to his interest in creative writing at Oberlin College and the fact that his adoptive mother was a storyteller. The suggestion is that Beah was encouraged by those around him to tell a more vivid story. Others have more charitably suggested that Beah simply got his dates mixed up, and his memory may have been unreliable because on his own admission he was high on drugs most of the time he was in military service. Beah has vehemently denied that he invented anything, however. In an article published in Publishers Weekly in 2008, Beah wrote, â€Å"Sad to say, my story is all true.†

The Progressive Era Essay examples -- essays research papers

The Progressive Era The progressive era was a time of great change, the way people thought and what they did began to change quickly. Industry and business also changed a great deal in this era, with the many new inventions and strong businessmen things where rapidly changing. The progressive era lasted about 40 years, from 1879-1920. In 1879 Tomas Edison invented the electric light, I guess you could say he just lit the way for may other inventions that people made during this time period. The progressives where middle class people that where mostly composed of young people who wanted things to change, they believed that educating people was the best way to overcome a problem. They formed volunteer organizations that people would come to and they would educate them on what they thought the problem was with something. Some of the organizations I found where: (American Bar Association, U.S Chamber of Commerce, National Association for the advancement of Colored People, and many others. I think that they did this to increase the awareness of a problem and try to fight that problem with strength in numbers and educations, both are very strong weapons when tackling a problem. Muckraking was another way people got their point across, they would find out all the information that they could on a person and they would basically, just drag their good name thought the mud, telling the people about, the things that they might not know, the corrupt things and bad deals and kickbacks...

Analysis of Major Characters in Great Expectations Essay

Pip is the main character of this story. The whole plot of the novel revolves around him and his metamorphosis into an adult from an immature adolescent.  1. Immature: pip was highly immature. This characteristic in him can be clearly seen in pg 59 where he says † but when she was gone, I looked about me for a place to hide my face in and got behind one of the gates in the brewery lane and leaned my sleeve angst the wall there, and leaned my forehead on it and cried. As I cried, I kicked the wall and took a hard twist at my hair; so bitter were my feelings so sharp were the smart without a name that needed counteraction.† Pip cries so much, suddenly begins to have such a low self esteem, why? Just because a girl came and commented that he had coarse hands, wore thick boots and â€Å"called the knaves Jack.† Instead of standing up for himself, pip simply cries. This goes to show how immature pip was.  Pip’s immaturity is also seen in his â€Å"romantic idealism.† Ever since his first meeting with beautiful Estella, he always thought of her in page 101 he says, â€Å"often after dark, when I was pulling the bellows for Joe, and we were singing Old Clem, and the thought how we used to sing at Miss Haveshams would seem to show me Estella’s face in the fire, with her pretty hair fluttering in the wind and her face scorning at me. Often at such a time I would look towards those panels of black night in the wall which the wooden windows then were, and would fancy that I saw her drawing her face away and would believe that she had come at last.† In spite of Estella being s o insulting he instantly falls for her, rather for her looks. This again shows the immaturity in pip. 2. Generous and sympathetic: pip was generous and sympathetic, a fact that can be seen in his numerous acts of kindness throughout the novel. In page ___ he sympathizes with Magwitch and helps him escape. A small boy going out of his way to help a wretched convict! This goes to show how sympathetic pip was.  Not just sympathetic, pip was large at heart. He was generous. This can be witnessed in page _____ where he secretly buys Herbert’s way into business. The third example to show that pip was generous is in page 137where he says, â€Å"as I passed the church I felt a sublime compassion for the poor creatures who were destined to go there, Sunday after Sunday, all their lives thru and to lie obscurely at last among the low green mounds. I promised myself that I would do something for them one of these days and formed a plan in outline for bestowing a dinner of roast beef and plum pudding, a pint of ale and a gallon of condescension upon everybody in the village.† 3. Had a great desire for self-improvement: pip always wanted to better himself, better his condition and better his status. This trait in him can be witnessed in page 66 where he tells Joe, â€Å"and that there had been a beautiful young lady at miss Havesham’s who was dreadfully proud and that she had said I was common, and that I wished I was not common, and that the lies had come of it somehow, though I didn’t know how.† Moreover his deep desire to improve in life, to be â€Å"Uncommon† is also seen in page 68 where he goes to one of his relatives, Biddy to get educated from her. He says, â€Å"when I woke up the best step I could take towards making myself uncommon was to get out of Biddy everything she knew.†Ã‚  In page 164 he asks Herbert to correct his mannerisms if he found them un-gentlemanly. He says, â€Å"I further mentioned that as I had been brought up a blacksmith in a country place, and knew very little of the ways of politeness, I would take it is a great kindness in him i.e. Herbert if he would give me a hint when ever he saw me going at a loss or going wrong.†

Li Ka Shing

Background Li Ka-shing, an icon of Asia’s economic rise in the postwar era, through his businesses employs 270,000 people in more than 50 countries. He also has made personal investments in Facebook and Skype, and is one of the world’s top philanthropists. He started his remarkable career making toys and later, plastic flowers. Succession Li  said his elder son Victor would be his successor at Cheung Kong and Hutchison Whampoa. â€Å"Victor will assume the stakes I hold in the listed firms, including the 40% stake in Cheung Kong and the 35% stake in Canada-listed Husky Energy,† Li told reporters. He will be responsible for Cheung Kong's group business in the future. † The current market value of Li's 40 percent stake in Cheung Kong and his 35 percent stake in Canada-listed Husky Energy is around HK$140 billion (US$18 billion). Victor  has been  the deputy chairman of Cheung Kong since 1994 and managing director since 1999; he is also deputy chairman of Hutchison. Li senior  is the  chairman of both companies. Richard, who ranked No. 960 with wealth of $1. billion on the same list and runs his own telecommunications empire, â€Å"will also have a very successful career†Ã‚  , pledging his â€Å"full support†. The move should help avoid a family feud – â€Å"there will be no conflict† among Victor’s and Richard’s businesses, said Li, who  Forbes  estimates is worth about US$25. 5 billion. Businesses controlled by Richard include PCCW Ltd. , Pacific Century Premium Developments and the HKT Trust. Li said he would support Richard’s  new projects with â€Å"cash,† and  the y ounger son’s assets  would increase â€Å"several-fold† through the father’s support. Richard is in acquisition talks with â€Å"several sizeable companies, Victor now holds two-thirds of Li Ka-shing Unity Holdings Ltd after Richard transferred his one-third holding in the family trust to him on July 16, 2012, according to a filing to the Hong Kong stock exchange. Li Ka-shing will continue to hold the remaining third of the trust, which controls Cheung Kong (Holdings) Ltd, Hutchison Whampoa Ltd and other affiliate companies. Victor has three daughters and a son, Michael, and Richard has three sons, the eldest being Ethan. ttp://www. campdenfb. com/article/li-ka-shing-plans-succession-avoid-family-feud http://www. forbes. com/sites/russellflannery/2012/05/28/hong-kong-in-transition-elite-family-businesses-are-facing-change/ http://english. sina. com/business/p/2012/0721/488324. html Challenge Li’s challenge may be that his model is outdated. Hutchison trades at a discount of 37 percent to its component parts, according to Credit Suisse, suggesting it might be w orth two-thirds more if it were broken up. But while Victor Li is there to ensure continuity, he may create most value by deviating from his predecessor’s grand plans. Recommendations Some of Asia's largest listed companies are family run, and succession plans are tightly held secrets, often only revealed through wills at the death of their founders, leading to bitter internal feuds. It is a positive move of Li to have clear-cut who is having what, avoiding potential struggle for shareholding, and it is good for the long-term stability of the group. Li also assures a loyal follower Victor who shares his values, and the newcomer will be surrounded by a team of long-time Li acolytes. The succession is set to be smooth and no major impact is expected on the management. Victor has been number two at Cheung Kong Holdings and Hutchison Whampoa since the 1990s. There is no surprise for his succession. Besides, there is an insurance policy. Victor will head a board followed his father for long time. Cheung Kong’s directors have served for an average of 21 years. Even the independent directors have served for an average of 19 years. However, continuity alone doesn’t make a legacy. In the Li empire, Victor will need new tactics. Growth of Cheung Kong and Hutchison Whampoa is slowing. They have delivered almost flat returns over the past five years. Victor will need to create a more sustainable, and environmentally less destructive model. http://blogs. reuters. com/breakingviews/2012/05/30/li-ka-shing-opts-for-succession-china-style/

3 Great Options for Online Homeschooling Support

3 Great Options for Online Homeschooling Support SAT / ACT Prep Online Guides and Tips The magic of the internet has dramatically increased the resources available to the average homeschooler. Through online homeschooling resources, homeschools can supplement their existing coursework, parents can get curriculum support, and students with irregular schedules can stay enrolled in high school! In this complete guide to online homeschool, we’ll introduce online homeschooling, discuss the pros and cons to online homeschool, and go over the types of online homeschool and the benefits and drawbacks to each type. We’ll also provide examples of each type of program! An Introductionto Online Homeschool Online homeschooling refers to a homeschooling program (so, no going to a brick-and-mortar building!) where some or all of the learning is done through the aid of an online program. Other than that, it’s a pretty broad term. Online homeschooling could mean you are doing a complete, comprehensive program at an online high school. It could also mean one or both of your parents are your primary teachers, but you are supplementing their teaching with one or two online homeschool classes. It could even mean your parents are getting their homeschool curriculum from an online source, which they are then teaching to you. Thus, â€Å"online homeschool† can refer to pretty much any internet-based homeschooling coursework resources. Should You Use Online Classes in Your Homeschooling Program? There are both pros and cons to making use of online material and courses in your homeschooling program. Benefits of Online Homeschooling There are several benefits to online homeschooling: It's Flexible Online homeschool allows for increased flexibility in schedule. This is really important for students who may be engaged in lots of travel for athletic competitions or who have other constraints that cause them to have irregular schedules. Being able to work on the road and at unusual times is a must for students who are pursuing activities that aren’t compatible with a typical Monday-Friday 8 am-3 pm school schedule. It Doesn’t Rely Solely on Parent Expertise Even if your parents are amazing homeschool teachers, there may be areas where they don’t have enough knowledge to effectively teach you, especially when you get older and start taking advanced and AP classes. In this case, online homeschool classes can fill in the gaps and make sure you get the instruction you need for advanced coursework. Can Have Engaging, Interactive Teaching Methods Some online homeschool programs will mostly involve you reading an online textbook and doing standard exercises. However, there are some programs that strive to present material in an engaging and interactive way using the online/computer-based medium. This can help keep you from getting bored. Validated Grades A benefit to online homeschool programs that give grades is that it helps validate your grades beyond just a parent transcript. If an online, independently run and graded course gives you high marks, that’s going to serve as evidence to colleges that you really know the material and help validate your homeschool grades and achievements. If you're a competitive ice-skater, you might need online homeschool so you can skate and graduate! Drawbacks of Online Homeschooling Here are some of the drawbacks: Self-Motivation Is Required The less structured and monitored a program is, the more self-motivated you’ll need to be. So if you’re doing a very self-guided program without too many deadlines or checkpoints along the way, you will really need to keep yourself on track. A parent can help with this, of course, but it will ultimately be up to you to make sure all the work gets done. Quality Control The landscape of online education is very uneven, so you need to really make sure that whatever online homeschooling program(s) you use are high-quality. Ideally, they would be accredited in some way and have good reviews from other students. Other things to look for include instructor availability, quality and comprehensiveness of content, and workload. Less Curriculum Flexibility Online homeschooling, particularly complete online high school programs, offer less curriculum flexibility than traditional homeschooling, where parents can create the entire curriculum tailored to student interest. For example, parents can arrange every subject in short units around single topics or make all of your math work relate to cooking and baking to keep students interested. With online programs, it’s less individualized and more outside of parental (and student) control. Cost In general, most online homeschooling resources cost money, and they can be quite expensive! At some providers, an individual course can cost a thousand dollars, and enrolling in a complete online high school can cost several thousand dollars a year! Unfortunately, it takes more than a simple stamp to guarantee quality. The 3 Types of Online Homeschool: Pros and Cons There are three overall categories of online homeschool: single classes, complete online schools or programs, and online curriculum support for homeschooling parents. Single Classes As a homeschooler, you can take single classes in specific subjects from a variety of online course providers to supplement your home learning without having to enroll in a complete online high school. Pros: By taking single online courses, you can pick and choose from a variety of sources. This allows you not only to try out different providers and formats but dramatically expands your potential course catalogue! If you can find an online provider that offers a course, you can take it! Taking single courses is also, in general, going to be more cost-effective than enrolling in a complete online high school. You can select only those courses that you absolutely need an online provider for and save money on the ones where you don’t. Cons: The more different providers you take courses from, the more logistically complicated it will be! Not only will you have to make sure that none of your courses clash in terms of scheduling, deadlines, and so on, you will need to request transcripts from all of your coursework providers when it’s time to apply to college! Examples: Here are several examples of providers that offer single classes for online homeschool. Note that many online high schools also offer the option of taking single classes. PA Homeschoolers - This homeschool-student only provider offers robust online AP courses for high-schoolers. Reviews of the site praise the individualized attention that students get from instructors and the overall quality of the curriculum and learning experience. Florida Virtual School - This public online course provider has both single course and complete curriculum options; with FLVS Flex, homeschoolers can supplement their coursework with select online courses. UC Scout - The University of California system offers this online course provider specifically so that students can satisfy California universities’ A-G requirements online (the A-G requirements are fairly standard high school college prep course expectations). But anyone can enroll in their courses! Taking single classes gives you access to a whole buffet of online courses! Complete Online Schools/Programs You can also enroll in a complete online high school program and take all of your courses through the same provider- like a regular high school, but in cyberspace! Pros: This is a great option for students in rural areas or with unusual schedules who still want to be connected to some kind of high school community. Some online high schools really make an effort to connect students, too, through things like extracurriculars. You will get a more consistent, cohesive academic experience from an online school as opposed to if you patch together classes from various online course providers, homeschool, and community college. Some online high schools even have pretty robust institutional resources like guidance counselors to help you apply to college! An online high school gives you the benefit of one simple, complete transcript from the school- which you won’t have if you take classes from multiple sources. This will make it logistically simpler down the line when you start applying to colleges. Cons: You have much less control and flexibility in an online high school versus traditional homeschooling or select online courses. You have to comply with the school’s rules about how many courses you can take, when you can take them, any prerequisites you need, and so on. You’re limited by the school’s course catalogue- if they don’t offer it, you can’t take it. Complete online high schools can be expensive! Many are private schools, in which case you may find yourself paying thousands of dollars annually. However, some states offer free public online high schools to students, so be sure to look into that. Examples: There are hundreds of online high schools out there. These are only a few examples. But if you are going to use an online high school, make sure that it’s accredited! Stanford Online High School - This rigorous, application-only online high school was created by Stanford University and features a lot of interaction with other students as a main selling point. It is fairly expensive, though! Connections Academy - This is a free, accredited online public high school. The Keystone School - An accredited, online private high school based in Pennsylvania but available to students everywhere. Also check out our massive list of over a hundred free online high schools! If you need to keep irregular hours to fuel your frog-hunting passion, online homeschool may be just the thing for you! Online Homeschool Curriculum Support If you’re a parent who is looking for predesigned homeschool curriculum to use with your children, there are tons of online homeschooling curriculums available out there. Pros: The major pro, of course, is that this can be an incredible time-saversince you don’t have to design the entire curriculum yourself. If you can find a well-designed, high-quality, positively-reviewed curriculum for a course, you can confidently use it yourself! Pre-designed curricula can also be helpful when you are familiar with the subject, but not an expert. It will give you a little boost in knowledge and effectiveness if the curriculum is high-quality. Cons: Quality control is an issue for any online homeschool curriculum. Since most curricula aren’t offered by accredited institutions, it can be hard to know that what you’re getting is the real deal. Ideally, you’d be able to look over some of the curriculum before purchasing or using it so that you can validate it. You’ll also want to try to find reviews from other users. Examples: Here are a couple of curriculum support options. Note that it may be the hardest to separate the wheat from the chaff with curriculum support sites because anyone can start up a website and upload a curriculum with little possibility of outside validation. Bridgeway Academy - In addition to single courses and an online high school program, they also offer a program for parents to connect with homeschool curriculum that meets their needs. Calvert Education - Calvert Education offers homeschool curriculum to parents with an online management tool and a support line. They also claim President Barack Obama as an alumnus! Imagine a 24-7 curriculum support line for all your 2 am math-instruction questions. Online Homeschool: Key Takeaways Online homeschooling resources are available from many sources. You can take individual courses, enroll in a complete online high school, or get homeschool curriculum online! Here are some of the pros and cons to online homeschool: Pros: It can offer flexibility for students with unusual schedules. It allows you to get taught by trained experts in a variety of subjects. Teaching methods can be interactive and engaging. An online course transcript helps validates other homeschool grades. Cons: You need to be self-motivated to learn in the online format. Quality control for online learning resources can be a problem. Less flexibility than traditional homeschooling. It can be expensive! There are also pros and cons to the different kinds of online homeschool: Single courses allow youtry out multiple providers and have access to more classes and are more cost-effective than a complete online high school. However, the more providers you take classes from, the more logistically complicated it is! A complete online high school keeps you connected to a high school community, gives a cohesive academic experience, and gives you just one simple transcript, but uou are limited by the high school’s regulations and course catalog. Complete online high schools can also be very expensive. Curriculum support is a less extensive option that can still be ahuge time-saver for parents, but quality control is often an issue with these resources. Online homeschool for everyone! Yay!

1965 Selma to Montgomery march Essay Example | Topics and Well Written Essays - 1500 words

1965 Selma to Montgomery march - Essay Example History 1). The civil war that had taken place previously had failed to eradicate the social barriers created by some institutions (U.S. History 1). In the south, after the war, there was the creation of laws that only highlighted issues of whites at the expense of African American (U.S. History 1). The situation remained until the beginning of the second part of 20th century. At this period various institutions begun to be sensitive to African American demands. The greatest progress was the school integration ruling of 1954 by the Supreme Court (U.S. History 1). Later, there was a development of peaceful protest by Dr. Martin Luther King Junior. Consequently, this led to increased marches, boycotts, sit-ins, and freedom rides in both the American south and parts of north (U.S. History 1). Moreover, public opinions changed and showed a significant deal of sympathy towards the African Americans. However, there remained obstacles to complete racial equality. Although legal equality had made progress for African Americans, there was reduced economic equality and social acceptance (U.S. History 1). Consequently, this led to increased activism in the 1960s. Malcolm X, the Black Power Movement leader, advocated for the policy of non-violence, and he inspired most of the movements in this period (U.S. History 1). A reflection on the civil rights movements helps in highlighting the role of Selma to Montgomery marches. ... History 1). Consequently, there was reduced hopes for achievements of equal rights among African Americans. Moreover, there was increased discrimination in various states, in the north and south. For example, there was approval of laws creating schools and public facilities for each race (U.S. History 2). One of such laws was the Jim Craw laws that reinforced the white supremacy that had diminished during the reconstruction era. The discrimination was seen as whites, and blacks carried activities in different areas such as in school and restaurants (U.S. History 2). In addition, there was also discrimination in public spending. For example, teachers in white schools were paid better wages, and white schools were well maintained while in black school teachers were paid poorly, and the situation was poor (U.S. History 2). Additionally, there was a failure of implementation of Brown decision on segregation in the south. In fact, one decade after the decision, fewer than ten percent in s outhern public schools had integrated (U.S. History 2). This is because the ruling failed to address the issue that led to segregation such as separate restrooms, bus seats, or hotel rooms (U.S. History 1). There are various reasons for the inspiration to revolution. One of the people that inspired revolution was Rosa Parks. She boarded a Montgomery bus and refused to pave the way for the white passengers (U.S. History 3). This was followed by her arrest, and she was fined $10 (U.S. History 3). Consequently, revolutions began in various parts of the country. One of the instrumental persons for the revolution was Martin Luther King Junior (U.S. History 3). After the Rosa Park development, he organized the boycott of Montgomery’s buses (U.S. History 3). They wanted for equal
