Investigation Into Osmosis :: Papers

Investigation Into Osmosis Aim === The aim of this experiment is to compare the change of mass of potatoes when they are in a Starch and water solution. The reason the mass would changes is due to osmosis. Introduction ============ [IMAGE] Osmosis is the process of water passing from a region of high concentration of water, through a semi-permeable membrane to a region of low water concentration. Osmosis occurs when there is more water on one side of the cell than the other. In the example to the right the small blue particles represent water. There are more of the small blue particles on the left-hand side so the number of water molecules on each side would even out until the water cells are in equilibrium. The experiment we are doing is to see how much of the water has diffused and how much mass the potato lost or gained. Variables ========= I chose to investigate the mass of potato and volume of solution lost or gained when potato is put in water/ sucrose solution. The variables I didn't change were:  · Start volume of solution  · Start mass of potato  · Surface area of potato  · Amount of sunlight  · Length of time  · Type of potato  · Temperature The variables that I changed were:  · Concentration of sucrose/ water solution. Preliminary work ================ We did a preliminary experiment to check that the measurements and amount time would give us clear enough results. Method ====== We took three test tubes with 10ml solution in each. One with 0M sucrose One with 0.5M sucrose and the other with 1M sucrose, a test tube rack, three bungs and three pieces of potato. We weighed the three pieces of potato and cut them down to make them the same mass to make it a fair test. Then we made the water/ sucrose solution using these measurements:

Physical Activity

CYPOP 4: Promote young children’s physical activity and movement skills 1. 1 Explain why physical activity is important to the short and long term health and well being of children Physical activity is important to the short term and long term health and well being of children. In the short term physical activity helps children to build muscle, develops the skeletal frame, develops the heart and lung function and helps prevent obesity. If children have enough physical activity a day which is said to be up to an hour it can help children get to sleep easier and sleep for longer periods of time.This can lead onto long term benefits as if the activity is outside it will also help to build up a good immune system so they are less likely to fall ill to the common cold or the flu. The outdoor environment helps the overall well being of the children as the outdoors makes them feel free which helps their emotional and social development, as it allow them to learn new skills and develo p confidence in playing alongside others. In the long term physical activity helps the children to become interested in sports and outdoor activities.This is a good foundation to build when the children are young because as they grow older children and young adults start to become less active so early physical activity is more beneficial for the child in the long term. If when children are young and do not take part in physical activity it is more likely that they will become obese later on in life which in turn could end up with them getting more serious diseases such as type 2 diabetes, cancer or heart diseases, it could also result in girls having osteoporosis later on in life. Physical activity does not mean expense.This could be that you go for walks in the local area and make it fun by having skipping/hopping/running races between lampposts etc and taking a ball so you can call at the local park for a kick around. This could also incorporate a nature trip to collect and see th ings, so children may not realise how far they are going. Indoor activities could include wii fit hour, which I incorporate as every child can have a go. There is also ‘keepy uppy’, which is a balloon that you pass around so it doesn’t touch the floor or musical statues for movement and balance. 1. Explain the development of movement skills in young children and how these skills affect other aspects of development. 89 CYPOP 4 1. 2 In order to achieve the physical skills required for the areas in the spider diagram, a mixture of movement skills need to be acquired in the right order. They include the following: Hand-Eye Coordination. Many activities require hands and eyes to work together. To catch a ball, for example, the brain needs to take information from the eyes and use it to inform the movements that have to be made with the hands. Foot – Eye coordination.Children have to learn to guide their feet. Climbing stairs and kicking a ball require this type of coordination. Balance. Balance is a complicated skill. Although it is one that most people take for granted. The ability to balance develops with age, with most children relying on visual input to balance. The development of these skills follows the development of the central nervous system (principally the brain and spinal cord) in babies and young children. The central nervous system is responsible for collecting, interpreting and sending out information to all parts of the body.Information is constantly collected via the body’s senses of taste, touch, smell, sight and hearing. This information is then transformed into electrical pulses that are carried by the nerves, up through the spinal cord and into the brain. From the information received, the brain then responds and sends out instructions to muscles, glands and organs using the network of nerves again. The whole process is surprisingly quick, which means the body can take action against possible danger, for exampl e, a person will instantly withdraw their hand from something that is very hot.In babies and young children the central nervous system has to mature. At first babies are reliant on the many survival reflexes they are born with. These are automatic reactions, but in order to gain control, the central nervous system has to learn how to interpret and control these responses. Gaining physical control. The rate at which babies and children gain control over their bodies varies enormously, but it is recognised that there are three key principles that underpin the gaining of control. Development follows a definite sequence.Movements and control develop in a certain pattern, which means that babies cannot walk before leaning to sit unsupported. Development begins with the control of head movements and proceeds downwards and outwards. Babies first gain control of their head and top of the spine before other parts of the body. This is thought to be a survival mechanism as it is important for babies to be able to turn their heads to feed. 90 CYPOP 4 1. 2 Development begins with uncontrolled gross motor movements before becoming precise and refined.Babies gain control over their arms before managing to control their hands and fingers. This principle is an important one to remember when teaching children new skills, such as handwriting, as it means that they will need to start making large letter shapes before using pencils to make much smaller ones. |AGE |HAND-EYE COORDINATION |MOVEMENT SKILL | |3 months |Can find hands and bring to mouth.

Over time, they are no longer reliant on adults to physically feed them, clothe them and move them from one place to anothe r. This gives children great confidence and also allows them to learn because they can now explore. Children are also able to use their new found skills to play more challenging games and also play together.The diagram below shows physical skills link to other aspects of children’s overall development. Griffin S 2010 Children and Young Peoples Worksforce 1st Ed Portsmouth Heinemann92 ———————– Travel (travelling movements where the child moves from one point to another such as running, jumping, skipping) Object Control (movements such as throwing, catching, dribbling which involve objects being sent, received, travelled with) MOVEMENT SKILLS Balance & Coordination Cognitive Development Much of children’s learning is linked to practical activities. This requires movement skills. There seems also to be a link between early physical movements and brain movements Physical SkillsLanguage Development Language develops wh en there are things to talk about. This is made easier when children can do things or move themselves to explore or see things. It gives them a reason to talk. Social Development Play in children’s early years is quite active rather than language based e. g. playing in sand, dressing up. Children can join in if they have developed the physical skills Emotional Development Builds children’s confidence. When children can do things for themselves, they are more likely to gain confidence. They can do things how and when they want. Children can also use physical skills to explore themselves e. g. draw, paint, dance

Leadership and Management Paper Essay

Ursula M. Burns is the Chairman and Chief Executive Officer (CEO) of Xerox. She has held this position for the last five years. She started out as a summer intern in 1980, and signed on in 1981. From then until she became CEO she has led several business teams and positions within Xerox, all along growing within the company. According to Fortune, she is the 22nd most powerful woman in the world. In addition to the Xerox board, she is a board director of the American Express Corporation and Exxon Mobil Corporation. Burns also provides leadership counsel to community, educational and non-profit organizations including FIRST – (For Inspiration and Recognition of Science and Technology), National Academy Foundation, MIT, and the U.S. Olympic Committee, among others. She is a founding board director of Change the Equation, and President Barack Obama appointed Burns vice chair of the President’s Export Council (â€Å"Xerox: Ursula Burns, CEO†, 2014). Leadership and Management Holding a management title does not necessarily equate to holding leadership skills. Leadership is defined in many ways, and depending on who you ask can simply be â€Å"coordinating the work of others†. However that is taking a very limited view on leadership. Leadership is a combination of rationale, inspiration, science, and art. It is said, â€Å"Leaders are thought to do the right thing, while managers do things right† (Hughes, Ginnett, & Curphy, 2009). Not all leaders are managers, look at Dr. Martin Luther King Jr. He is argumentatively the most important Civil Rights leader, however many would not look to him as a manager. According to Forbes, Ursula has made Xerox a profitable and viable company, this past year, Burns helped Xerox generate adjusted earnings per share of $1.09, up from $1.02 in 2012, and  post $21.4 billion in full-year revenue (Forbes, 2014). Her skills as a manager aided in building Xerox to the power-house they are today. Burns is responsible for the largest acquisition in Xerox history, and has allowed them to invest in business services, which is a $600 billion industry. Making these decisions requires hard decisions, including outsourcing, closing offices that are not performing well, and adopting a work from home culture. Because of this Burns has found herself on the 2014 Worst CEO list put together by 24/7 Wall Street and Glassdoor. Burns received a positive review from fewer that the 140,000 employees Xerox gained in the business services acquisition. Only 30% approved of her performance (Brown, 2014). Also something that does not help Burns gain leadership approval is the fact that she was paid on average $13 million dollars for 2010 – 2012, while over 500 people were laid off. While Burns has made moves in hopes of ensuring the stability of Xerox there are some that are calling for her to be fired. Burns’ recent letter to shareholders showed just how badly the transaction had go ne. Over the course of 2010 to 2013, revenue, net income and operating margins are flat to down. In particular, revenue fell 1% to $21.4 billion in 2013. In the fourth quarter, revenue dropped 3% to $5.7 billion. Net income was down 1% to $1.2 billion last year. In the fourth quarter, the drop was 4% to $311 million (McIntyre, 2014). When measuring success of a leader, there are many ways to do that and depending on which way is chosen could render different results. Using unit performance indices, Burns appears to be very successful as a leader. Unit performance indices can be used to examine what impact leaders have on the â€Å"bottom lines† of their organizations. Since she has taken over as CEO, Xerox shares have gone up 50% and the S & P is higher by nearly 100% (Brown, 2014). Based on this information and her average salary the board must be happy with how she is performing. However, another way to measure success is by subordinates ratings of effectiveness. Subordinates may be relatively satisfied or dissatisfied, may be motivated or unmotivated, may feel relatively committed or uncommitted to the organization, or may believe their leader is relatively effective or ineffective. Because Burns has found herself on the worst CEO’s list of 2014 it can be said that she has been unsuccessful as a leader (Hughes, Ginnett, & Curphy, 2009). Conclusion Overall it is important to remember that there are many dynamics to measuring leadership and management. Leadership and management can have many different meanings. Burns is a prime example of this. I believe she is an effective manager, because businesses are in the business of making money and her shareholders are happy. She also sits on the board of several inspirational companies like FIRST and Change the Equation, which could have many people looking at her leadership abilities. However, when it comes to Xerox her primary focus is making the shareholders happy, when could indicate she is not being a true leader in a way that motivates, inspires, encourages, or simply speaks to their employees.

Critical Analysis Essay Example | Topics and Well Written Essays - 250 words

Critical Analysis - Essay Example However, in this case it appears that the church has developed a political arm, which has a firm grip amongst the legislators. Secondly, what is the purpose of the writer? The author tries to shed light on gross violations in the Bahamian society which are going on unabated yet, the very agencies designed to safeguard against this take to shifting responsibilities and sometimes taking part in perpetuating these violations themselves e.g. the police, specifically in-charge of security, differ it’s duty by pegging it’s performance on the church’s intervention. Secondly, he condemns the church over its abuse of public trust by getting swayed into primarily pubic-related issues as opposed to their divine calling to administer matters of faith. Thirdly, he serves to open the eyes of members of the society to the realization that the overall change as desired by the state-to free Bahamas of the previous year mishaps-lies ultimately in themselves as citizens. He accomplishes this by showing failures of the legislatures, the security agents, and the custodians of the society such as the church. Thirdly, we examine the writer’s tone and feelings. The author is disapproving-even critical-about the ability of realizing the objectives of state for the New Year. He begins with much hope following the declaration by Bahamas Christian Council that calls on a change of people’s attitudes. This hope gradually ebbs away into despair, and he appears disillusioned in lieu of the rot within the very council empowered to oversee the transition. He appears enraged at one point when the BCB makes submissions to the local cable network and the URCA on suitable time to air adult-rated programming. To him, it seems the council is being hypocritical by at one point rightly condemning airing of pornography due to its impact on children, yet in the very same breathe appears to approve its viewing by the adult population (White field 3, paragraph 5). Shouldn’t the council

Environmental law has led the development of environmental management Essay

Environmental law has led the development of environmental management systems (and environmental auditing in particular) - Essay Example environmental record keeping and performance and impact review) include illustration of how particular industries or businesses have adapted to the rise of such compliance requirements consider whether there are any disadvantages to environmental auditing being influenced by concerns about legal compliance Word limit: 1500 words Your essay must be typed and all sources must be referenced. Hand in Date: 11th August 2011, 16.00 (generic resit CW submission date!) Marked work to be returned: To be negotiated Environmental law builds on reform movements from the early part of the 20th Century, including consumer protection and industry regulation legislation that was enacted through the House of Commons in the protection of the public welfare and safety of workers. As public awareness and understanding of the danger to the natural environment from pollution and waste produced by industry grew, more and more people began to organize into advocacy groups and political change or reform move ments to affect public policy. Domestic law was the early vehicle for these reform movements and legislative changes produced in this manner became part of the common law tradition that would be enforceable in court with damages or penalties. As the role of governmental authority in policing and regulating industry on environmental concerns became more prevalent, official environmental protection and monitoring bodies were organized on the national level as industry watchdogs. With the rise of this legislation and associated governmental agencies in environmental protection, the requirements for the consumer, business, and industry to abide by environmental regulations led to the development of testing and auditing procedures that would guarantee compliance over large sectors of the economy. This can be seen in automotive emissions requirements and fuel conservation requirements in cars, trucks, and other vehicles; in pollution emissions testing requirements for factories in the ene rgy industry and industrial production; clean water and anti-pollution requirements for companies; as well as in modern movements to initiate a global carbon trading regime based on carbon-credits and a business’ fundamental carbon footprint calculated through use of fossil fuels in all aspects of production. These developments highlight how environmental protection legislation has moved from national law to become a major aspect of international business through treaties, multi-national accords, GATT negotiations, the WTO, etc. Nationally in the UK, there are two main sources of modern environmental law, the 1974 Control of Pollution Act and the Environmental Protection Act of 1990. The 1974 CPA prohibited the dumping of waste material, sewage, and other pollution in public land, rivers, and oceans, â€Å"where— (a) the waste in question is of a kind which is poisonous, noxious or polluting; and (b) its presence on the land is likely to give rise to an environmental hazard; and (c) it is deposited on the land in such circumstances or for such a period that whoever deposited it there may reasonably be assumed to have abandoned it there or to have brought it there for the purpose of its being disposed of (whether by himself or others) as waste, shall, subject to the following subsection, be guilty of an offence and liable on summary conviction to imprisonment for a term not exceeding six months or a fine not exceeding ?400 or both or, on conviction on indictment, to imprisonment f

Terrorism and patriot act Coursework Example | Topics and Well Written Essays - 500 words

Terrorism and patriot act - Coursework Example Over 3000 people lost their lives. While America was still recovering from the shock of this barbaric act on its home soil, President George W. Bush lost no time in pursuit of the culprits. He ordered airstrikes on likely hideouts of Osama bin Laden in Afghanistan. At the administrative level, he promulgated the Patriot Act 2001 and established the Department of Homeland Security to help deal with all further threats and protect the borders of the USA and its people. Some sweeping powers were given to these personnel to track, apprehend and arrest possible suspects who wanted to harm America and its interests. The extent of these powers is a matter of debate, as many opine that it violates the rights of privacy and freedom as guaranteed under the U.S Constitution (Worrall, 2011). The Patriot Act was signed into Law by President Bush on October 26, 2001, just over a month and a half after the events of September 11. The Act has 10 separate sections, one each relating to enhancing domestic security against terrorism, surveillance procedures, anti-money-laundering, removing obstacles to investigations, information sharing, criminal law, terrorism intelligence and border security. Many sections were due to sunset after four years, but they were extended by President Obama in the larger public interest (CLDC, 2012). Among the most contentious of the powers under Section 213 is that of arresting someone on mere suspicion of being a terrorist, and that of searching his or her house without a warrant. Section 218 allows for wiretapping of such suspect’s every means of communication. Under Section 805, anybody even suspected of giving advice or assistance to a terrorist would be liable for arrest and prosecution. Granted that we have to nip terrorism in the bud, but such measures are a close call to violating the privacy and integrity of American citizens and go against the widely held precept of ‘innocent till proven

AN EXAMINATION OF THE EXTENT TO WHICH IMMIGRATION AND ETHNIC RELIGIOUS Essay

AN EXAMINATION OF THE EXTENT TO WHICH IMMIGRATION AND ETHNIC RELIGIOUS PLURALISM THREATENS THE WELFARE - Essay Example As briefly indicated in the above, ethnic and religious plurality constitute a potential threat to the very notion of the welfare state and its associate welfare citizenship. Plurality, implying conflict and difference, is antithetical to the very principles upon which the welfare state is predicated; the principles of shared identity, commonality and homogeneity. Even while conceding to the reality of the stated threat, however, this research will posit the claim that the management of plurality through multiculturalism has the potential to control and limit this threat. Understanding the extent to which ethnic plurality and religious diversity can function as a threat to the welfare state, is predicated on an appreciation of the implications of nation-hood and the social citizenry to which it gave rise. If the idea of the nation was invented, imported, and implemented by elites, it had also to appeal to the rest of the population who had not known dignity before the age of nationalism. Weber observes that "the idea of the nation for its advocates stands in very intimate relation to [their] prestige interests" (Weber 1978: 9251530). While the dominant political strata, such as feudal lords, modern officers, and bureaucrats are the primary exponents of a desire for the political power of the state, since "power for their political community means [political, economic, and social] power for themselves" (Weber 1978: 911/520), it is those who appropriate leadership in a community of culture, the "carriers of culture." who promote the idea of a nation (W eber 1978: 9261530). These are, for Weber, primarily intellectuals, but also artists, editors, authors, journalists, etc. (Weber 1946a: 1791485). While, originally, the "masses" had little to gain and little to lose within the political project of the state, or within the "cultural" mission of the nation (Weber 1978: 9211527, 9251530), they can increasingly identify with the nation-state's prestige due to the "democratization of state, society and culture" (Weber 1946: 1781485). The implication here is that the nation emerged as an imagined entity but attained concrete reality because of a shared social identity, a common culture which, in turn, gave rise to shared historical memories and heritage. In other words, the state is inherently founded upon shared social identity and it is the latter which gave rise to the nation, and not vice-versa. Within the context of the stated, the nation may very well be an imagined entity but it, nonetheless, bestows identity upon its populace (Gre enfield, 1992). Citizenship derives from the nation which, in turn, emerged as a direct outcome of
