The reaction between zinc and copper sulphate Essay Example

The reaction between zinc and copper sulphate Paper To investigate the affect of varying the amounts of zinc in the reaction between zinc and copper sulphate has on the rate of reaction. Background Knowledge My experiment is based on the theory of: A more reactive metal can displace a less reactive metal from a compound For examplThis type of reaction is known as a single displacement. This is when one element trades places with another element in a compound. The reaction that I will be looking at is zinc-replacing copper. This happens, as zinc is higher in the reactivity series than copper. The equation is shown below important aspect of these experiments is that they are exothermic. An exothermic reaction gives out heat as a source of energy. A reaction that is exothermic uses less energy to break the old bonds than is emitted to create the new bonds therefore heat is given off. The higher the energy given off, the higher the heat will be. The possible independent variables that could be investigated are: i The mass of zinci The pressure of the surrounding atmosphere i The concentration of the copper sulphate i The surface area of the solid reactant, i. e. the zinc i The volume of copper sulphate i The light intensity. The amount of times the solution is stirred The dependent variable that I will be measuring will be the temperature change of the reaction. To do this I will have to measure the initial and final temperature of the reaction. Preliminary experiments I conducted preliminary experiments using 1g of zinc, in order to predict, with greater accuracy, the outcome of my experiments. It showed that the experiment was going to be exothermic, and that the temperature given off increased as the experiment progressed. I also decided that I would only time the experiments for a maximum of ninety seconds each, as this was ample time for the results to be recorded onto a graph. Apparatus To do the experiment I will need the following equipment: We will write a custom essay sample on The reaction between zinc and copper sulphate specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on The reaction between zinc and copper sulphate specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on The reaction between zinc and copper sulphate specifically for you FOR ONLY $16.38 $13.9/page Hire Writer Powdered zinc In powdered form as this increases the surface area and gives better results Copper sulphate solution (0. 5M) Measuring cylinder To make sure the volume of copper sulphate is controlled Timer To time the 5-second intervals Weighting scales To accurately measure the amount of zinc Polythene cups polythene, as this is a heat insulating material. Using a different cup for each section of the experiment so that each one is fair. Also using plastic lids to stop any unwanted substances from interfering with the experiment and to stop heat from being easily lost. Thermometer To measure temperature changes from start to intervals to the final temperature. Method During this experiment I will be measuring the temperature given off as I expect the reaction to be exothermic. I will use 25ml of copper sulphate solution and 0. 8125 grams of zinc in each experiment. I manage to work this out using Avogadros theory of moles. First, I had to work out how many moles there are in 25ml of copper sulphate at 0. 5M. We need to convert the ml units into dm units. I therefore divided the 25 into 1000. I timed this answer by how strong the concentration of the copper sulphate was, 0.5M. Consequently, we have the sum (25/1000) x 0. 5= 0. 0125 moles of copper sulphate. We then need to times this number by the atomic weight of zinc, which is 65. 0. 012565 = 0. 8125 grams. This is the amount of zinc needed to disassociate copper in 25ml of copper sulphate solution at 0. 5M. It is important to note that the starting temperature of each experiment will be 25oC. I will record the temperature change in five-second intervals from zero to seventy. I have to make sure that the zinc used is definitely powdered zinc as any strips or lumps of zinc would alter the rate of reaction due the surface area. I will record my results in a table and then convert the data onto a graph. I will do this by plotting temperature against time. By drawing a line of best fit we can interpret the rates of reactions by calculating the gradient. I will repeat my experiment to ensure accurate and fair results. 1. Measure out 25cm3 of 0. 5M copper sulphate solution using the measuring cylinder 2. Pour the copper sulphate into the polystyrene cup 3. Put the thermometer in and wait until the temperature reaches 25oC 4. Using the weighing scales, measure out   grams of zinc. 5. Add the zinc, simultaneously start the timer and put the plastic lid on immediately. 6. Stir the solution using the thermometer as a rod. 7. Record the temperatures at five-second intervals. 8. Repeat experiment for accurate results. Safety There is a possible hazard when carrying out this experiment as the copper sulphate solution or the zinc sulphate solution could be an irritant to the skin therefore contact with the skin should try to be avoided. Goggles must also be worn to protect any harmful substances from entering your eyes. If contact is made with the skin during the experiment you must wash the affected area thoroughly. Prediction I predict that this experiment should be a displacement reaction. Therefore the copper in copper sulphate should be displaced by the zinc to form zinc sulphate and copper. This should occur as zinc is higher in the reactivity series than copper. The reactivity series is as follows: Element Symbol Group Number Potassium K 1 Sodium Na 1 Lithium Li 1 Calcium Ca 2 Magnesium Mg 2 Aluminium Al 3 Carbon C 4 (Non-Metal) Zinc Zn Transition Metal Iron Fe Transition Metal Tin Sn 4 Lead Pb 4 Hydrogen H Non-Metal Copper Cu Transition Metal Silver Ag Transition Metal Gold Au Transition Metal Platinum Pt Transition Metal Most Reactive Least Reactive As I am varying the amounts of zinc, I can predict that the greater the amounts of zinc the faster the rate of reaction. This is because there is more reactant for the copper sulphate to react with. Therefore the temperature should rise in direct proportion the mass of zinc. Heat should be given off so I can predict that the experiment will be exothermic. Conclusion From my experiment I can conclude that it was an exothermic reaction, which shows that my prediction of this was correct. The graphs show that as the reaction time increases, the more the reactants give off heat energy. The lines of best fit highlight an error in my prediction as I predicted that the greater the amounts of zinc the faster the rate of reaction. From the gradients of the lines of best fit we can see that this is untrue. In both experiments the 1. 11g of zinc does not have the fastest rate of reaction and the temperature does not rise as high as 1. 01, 0. 91 or 0. 81 grams of zinc. I also predicted that the mass of zinc would rise in direct proportion to the temperature. We can see that this prediction is not true as then you would expect the temperature to almost double from 0. 41 to 0. 81 and from 0. 51 to 1. 01, which does not happen. Evaluation In general my experiment has been a success as it has produced fairly accurate results. The reason for the experiment not following the exactly correct pattern could be: Not all the zinc reacted with the copper. Some heat might have escaped from the open cup. There could have been errors in the reading. The stirring could not have been thorough and consistent. These results can be further improved by: Using a more insulating lid to prevent heat loss. Using more accurate and sensitive scales. Using a pipette or burette instead of a measuring cylinder will increase the accuracy of the measuring of the copper sulphate. I could improve my results to my experiment if: More repetitions of the experiment were done. This would provide more results and add to the evidence for the experiment and also increase accuracy. The experiment was tried with different metals, ones that are at different levels in the reactivity series. This would be done to see how the use of different reactions change the temperature and energy changes and if the theory still works with different metals. Also, using salts with a metal lower in the reactivity series than the base can show whether distance in the reactivity series affects the energy change. Different concentrations of the copper sulphate were used. This can also show the difference between the temperature and energy changes. Data logging could be used so that there is now chance in human error in the experiment. Results Repeats in bold Amounts of Zinc (g) Starting Temperature (oC) End Temperature (oC) Temperature Change (oC) Average Temperature Change .

Psycology Essay Example

Psycology Essay Example Psycology Essay Psycology Essay This is a psychological reflective essay to examine and gain a greater understanding of self-harm. (www. Mild. Org. UK) I shall utilities Gibbs model of reflection (1988) to structure my essay and formalism my thoughts, pollens and research. I will reference my work using the Harvard system of referencing. (www. Elbow. Angela. AC. UK) Description: Whilst working as a cycle responder in central London I was requested to attend to a patient reported to be in a collapsed state and bleeding. Feelings: As I approached the scene I was cautious and slightly apprehensive, concerned about he causes of hemorrhaging, collapse and my own safety. My patient was a late teenage female, her overall appearance was one of neglect, but overall fairly well looking, a visual primary survey indicated this was, at this point not a time critical patient. She was on her own the sleeves of her clothing were blood stained and she smelt of alcohol. She reported to me she had a history of self-harming which was the cause of the blood staining. The lacerations were deep and with her permission, I dressed the wounds, suggested she went to hospital and requested a vehicle to rainspout her. I felt pity for my patient that she was In such a state and driven to such drastic measures. I was curious to how she had managed to self-harm as the idea of deliberately harming oneself is difficult to conceptualize as we spend our time attempting to avoid harming ourselves. I was quite repulsed by the deep scaring from previous episodes which made me question her reasons and motives behind what she was doing and her state of mental health. I felt concern that self harm was evidence of an undiagnosed mental disorder and may possibly be linked to future suicide attempt. Evaluations: I was glad she had she had decided to seek help on this occasion by calling 999, It would have been better If she called before she had self harmed. I was confident we could get the help she needed though she may have felt frustration going through the accident and emergency process as it can sometimes be a slow process. I would have been happier if she had accessed the correct treatment pathways through her GAP. I was concerned she may have left the hospital before she had been assessed and self harmed again. Analysis: Eighty percent of self-harm involves stabbing or cutting the skin with a sharp object. (www. Mentholated. Org. UK). Psychological factors that affect self-harmers: Abuse during childhood, bereavement, troubled parental or partner relationships, war, poverty, and unemployment may also contribute. Its estimated 30% of individuals with an autism spectrum disorder WI self-harm though patients with other diagnoses may also self-harm, suggesting pathways to self-harm would Include those with depression, anxiety disorders, eating disorders, post-traumatic stress people who self harm have no form of mental illness and the causes may be substance misuse, dependence and withdrawal, genetics, bullying, abuse (sexual, emotional or physical), neglect, school/work pressures, family financial difficulties, housing problems, relationship troubles, family problems, bereavement, loneliness or isolation, eating disorders. Or perhaps struggling to come to terms with sexuality, or any experience or event that causes negative feelings, thoughts and tensions. For some self-harmers the relief is primarily psychological, while for others this feeling of life comes from the beta endorphins released in the brain. Endorphins are endogenous voids, (medical-dictionary. Defenestration. Com) an opiate-like substance, such as an endorphin, produced by the body. They are released in response to physical injury, they act as natural painkiller, and can induce pleasant feelings which would act to reduce tension and emotional distress. Deliberate self- harm may become a means of seeking pleasure. Many self-harmers report feeling very little or no pain while self-harming and, for some a positive pleasurable experience. Strong, M. 1999), Many self-harmers report feeling very little to no pain while self-harming. Many people experiencing various forms of mental ill-health do have a higher risk of self-harm. ( Slinky, E. D. 2007) Also self-harm can present in the high-functioning individual who have no underlying clinical diagnosis making identifying a potential self harmer difficult and making the concept of self harm difficult for other reasons. Though its common in the younger person, generally starting at puberty through until mid twenties. Self-harm in young children is fairly are but reported cases are starting to increase. Self-harm is also apparent in high- functioning individuals who have no underlying clinical diagnosis. (Slinky, E. D. 2007). Self-harming behavior is generally most common in adolescence and young adults, usually first presenting between the ages of 12 and 24. (Mental Health Foundation, 2006) Self-harm in children is considered to be relatively rare, but the rate has been increasing since the sass (Thomas B; Hardy S; Cutting P 1997). Self- harming behavior can nevertheless occur at any age, including in the elderly. (Pierce, D. 1987) . There is more risk of serious injury and suicide attempts in older people who self-harm. (National Institute for Clinical Excellence 2004), Self-harm is often described as an experience of diversification or a dissociate state. (Natal- tong, D. 2008. ) There are vari ous causes leading to self-harm, but it can affect anyone of any age, sex and state of mental health but certain groups of individuals seem to be at a higher risk. A stigma is attached to self-harm, many people will go to great lengths to hide what they are doing. The I-J ONES study reported only two motives: to draw attention ND because of anger. For some people harming themselves can be a means of drawing attention to the need for help and to ask for assistance in an indirect way. It may also be an attempt to affect others and to manipulate them in some way emotionally. However, those with chronic, repetitive self-harm often do not want attention and hide their scars carefully. Conclusion It would have been an advantage to have a greater understanding of self-harm the that understanding. Action plan The treatment I provided would be the same should a similar situation arise. Ensure he safety of my patient and myself, dress any wounds that required dressing, reassure the patient and ensure they access the appropriate treatment pathway. I would be able to provide better treatment because I would be more aware of the causes. For some individuals, an episode of self harm may be easily triggered by a significant life changing event, but for others the day to day fluctuation in their thoughts and feelings and moods can be too much to bare for them and they react with self-harm. Simple stresses such as a breaking a glass, a loud noise, or running ate for an appointment might be enough to create a tension that is so overwhelming in the individual that they self harm to cope with this. Self-harm can be a method of relieving stress. For some, self-harm can become a habit; something they routinely do to survive on a day to day basis because they dont know what else to do, simply a coping method. As a coping mechanism, self-harm can become psychologically addictive because, to the self-harmer, it works; it enables him or her to deal with intense stress in the current moment. Occasionally a positive experience can be a thaw to self-harm. I would try to tackle the deeper underlying problem by being aware that for all individuals the starting point for recovery is to become aware of their reasons for, and what drives them to self-harm. Then armed with this knowledge that they can learn to respond differently to their difficulties and recognize the pathways to self-harm. Im aware that recovery is always possible, however lost and overwhelmed the person feels. Although self-harm provides a temporary fix to a problem, the relief is short lived, and is quickly followed by other feelings like shame and guilt. Meanwhile, it keeps the self-harmer from learning more effective strategies for feeling better. Helped. Org states that; the first step is to confide in another person. It can be scary to talk about the very thing you have worked so hard to hide, but it can also be a huge relief to finally let go of your secret and share what youre going through. Deciding whom you can trust with such personal information can be difficult. Choose someone who isnt going to gossip or try to take control of your recovery. Ask yourself who in your life makes you feel accepted and supported. It could be a friend, teacher, religious leader, counselor, or relative. But you dont necessarily have to choose someone you are close to. A service I could easily provide as my role as a paramedic being first on scene after a patient has Just self-harmed. There is an uncertainty about which forms of psychosocial and physical treatments of patients who harm themselves are most effective, and further clinical studies are required. But providing support and listening to the causes is definitely the first step. Hawthorn, K. Et al. (1998), further clinical studies are required.

Ethical Steps in Decision Making Essay Example | Topics and Well Written Essays - 500 words

Ethical Steps in Decision Making - Essay Example As a psychiatric nurse, I work in the therapy section and yesterday while on duty, I was faced with a dilemma. I received young male patient, who had on several occasions attempted suicide. On checking his report, there was a record of symptoms pointing to severe depression. I thus consulted with the mental health nurse, who affirmed that indeed the patient had shown signs of depression during examination, moreover that the psychotherapist in charge was aware of the mild symptoms, but had advised against any further follow-up on the patient, who, he considered was experiencing a post-traumatic stress disorder. Confronted with a dilemma, I utilized the five steps involved in the ethical decision making process, so as to come up with a solution. The first step I took, as set forth by Aiken (104) was to analyze the data I had, in order to come up with relevant information concerning the situation. Thus, after an interpretation of the data I had, I noticed that the patient had displayed several suicidal attempts in the past single month. I therefore concluded that, the physician had let the symptom pass. I thus went on to take the second step, which involves spelling out the dilemma at hand, as suggested by Aiken (104). I was torn between administering therapeutic treatment meant for depressed patients in order to prevent possible harm after discharge, or discharge the patient after slight recovery, as ordered by the doctor, since the mild symptoms had been treated. I was thus left with the option of moving on to the third step. This involved the identification of all the causes of action that can be taken, without emphasizing on the possible results (Aiken 104). I thus followed my judgment, in line with the best interest of the patient. Considering that the psychotherapist had chosen not to order a therapy meant for depressive patients, I went to the chief physician and made known my findings. Thereafter, I examined the merits and demerits that

Italian Baroque Assignment Example | Topics and Well Written Essays - 250 words

Italian Baroque - Assignment Example He introduced tension and high drama through the technique of chiaroscuro that brought into sharp focus (almost like a spotlight that is used highlight action or an actor on stage) the main protagonists of the event and chose to immortalize the most poignant moment of the episode – the actual act of murder – by capturing the scene when the killer is about to thrust the blade in the torso of the fallen saint. The saint, it appears, recoils as he falls thus possibly signifying the ultimate victory of Christianity and the parallel placement of the killer’s arm and the angel’s outstretched hand perhaps implies instant martyrdom and sainthood of Saint Mathew. The killer is unaware of the angel and only Saint Mathew can view it thus hinting at his divinity. The marvelous use of light and shadow depicts the bystanders and their sense of horror in one blinding flash as if lightning struck when the murder took place. The painting appears to capture that poignant mo ment of high drama and unbridled emotion as only a masterpiece can. Critics are of the opinion that Caravaggio was hugely influenced by the large scale grandeur that was so very common in creations during high renaissance period and some say that he was very heavily inspired by The Martyrdom of St Peter the Martyr by Titian while executing his The Martyrdom of Saint Matthew. The Martyrdom of Saint Matthew by Michelangelo Merisi da Caravaggio is one among the trilogy of immortal exhibits of Baroque school of painting that is so often hailed.

Transportation and Distribution Management

Transportation and Distribution Management Transportations and distribution industry plays an important role in bridging the gap between the producer and the consumer. Forms of transportation available include air, water, rail and land. The transport industry is one of the driving forces for economic development. The cost of transportation is a major cost that all firms in this industry would like to reduce (Markowitz, 2011). The economic benefits of reducing transportation cost are notable and are a direct way of improving profits for any firm. According to Hines (2004) the question of how to reduce these cost remain one of the constantly explored by many transportation firms. Each firm desires to develop an effective strategy to reduce the costs. Distributions is important since it ensures production and needs are in balanced thus it is an important part of the economy. Moving products from producers to the consumers regionally, nationally and internationally can account for more than half of the total cost of the products. Therefore, the management of transportation and distribution should focus on the economic aspects (Rodrigue, et al. 2010). Efficiency and effectiveness of the transport system is vital in reducing the costs. Subsequently, management of the operations includes analysis of the costs of everything involved. Operations administration is carried out depending on the nature of the products or services that the organization is dealing in. Discussion and Analysis On 31 November 1981, I and five other partners came together and initiated a privately own a transport company Swift world transport Ltd. The company provides innovative, cost effective and reliable transportation of food products. Swift world transport Ltd specializes in food products shipment and carriage between various states and towns. After realizing that an opportunity exists in coordinating of food products, we launched a strategy to fill the void. Our trucks and carriers deliver food products to one destination and return with another load to another destination. The company desires not only to meet customerà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s expectations but also to exceed it every time. Currently we have over 500 trucks operating around five states. Since transport costs account for a considerable portion of the selling price of food products, we put emphasis on making smart economic decision (Rodrigue, et al. 2010). Swift world transport Ltd. Deals with a wide range of food products. The products range from cereals, soft drinks, biscuits and cookies, baked goods, ready meals and frozen foods. Other products that we transport in smaller quantities include dairy products, honey and seafood. Swift world transport Ltd. Is ISO-certified and will be celebrating 30 years in existence late this year. Though the company began from humble beginnings, it has grown to be one of the market leaders in transportation of food products. It has more than 300 employees and is strategically located with its head office in New York. Swift world transport Ltd upholds integrity and abides by the rules and regulations in the transport industry (Markowitz, 2011). At Swift world transport Ltd we value the customers hence we use the latest technology and equipments in handling the products to meet customerà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s needs of quality. We have refrigeration services to keep perishable products from being spoilt. The ministry of health officials has approved our warehouses as safe for storage of edible products. Our trucks are monitored via satellite hence we have an error free billing system (Rodrigue, et al. 2010). Swift world transport Ltd. Has three main departments. The first department deals with the transport infrastructure. These include the trucks and the sea vessels. The second department includes the food handling facilities such as refrigerators and warehouses. Finally, the last department ensures that there is always adequate supply of the products depending on the demand. Physical distribution involves the transportation of the food products from the various sources to the customers. The manager directing the physical distribution has the responsibility of assessing and controlling the cost of transport. He is also charged with the responsibility of ensuring the most efficient way of storing them. This in some cases may require warehouses hence inventory control. A manager should thus ensure that the right goods arrive at the proper destination in the right condition and to the correct client. As explained by Halldorsson et al. (2003) the goods should be in the right quantity. The transportation strategy adopted by the Swift world transport Ltd swiftly responds to all aspects of our operations with priority on customers and suppliers. The strategy acknowledges customer requirements as an important aspect of all its activities. The supply chain is a involves movement of products from suppliers to the customer. The transportation activities should focus on meeting customer needs. Transportation and shipment must therefore progress according to the timings (Rodrigue, et al. 2010). Customers require that products be delivered at their premises on a particular day and time. This needs to be accomplished in order to provide customer satisfaction. Being able to meet these deadlines has given Swift world transport Ltd a competitive advantage over other firms. The size of our firm also causes our customers to trust in our ability to be reliable. They believe that small firms are not reliable. Comparing performance is important for the firm to know how well our stra tegies are working (Larson, Halldorsson, 2004). In order to remain economically sound, we measure our expenses every now and then in order to have tight control over them. Estimation of general expenses and freight costs assists the company in budgeting. A supply chain is a system that brings organizations, people, information and other resources in bridging the gap by ensuring that goods and services move from supplier to consumers. Supply chains ensure that goods are delivered to the end user. The management of a supply chain involves planning and management of activities ranging from sourcing, procurement and the logistics. At Swift world transport Ltd. coordination and collaboration with the suppliers and customers and other third party service providers is our priority. The company has created a supply chain that integrates all activities with the main responsibility of linking our suppliers and the customers (Rodrigue, et al. 2010). A model of a supply chain begins from receiving the products from producers and suppliers and ends with the delivering to the consumer. Swift world transport Ltd adopted the model whose framework is developed on business processes that are not only cross firm but also cross functional. A team manage s the cross-functional processes with representatives from purchasing, finance, logistics and research and development (Halldorsson, et al. 2003). Since each process interacts with customers and suppliers at some point, customer relations and supplierà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s relations form an important part in the supply chain. The company must make the right decision when moving products from one point to the other. Distributing products faster and cheaply leads to higher profits and more satisfied customers. In order to do this, Swift world transport Ltd stays informed on the current trend within the industry. For illustration, most companies are moving in the southern states because where doing business is more cost effective. The company has been analyzing facts and trying to make a decision whether to move south. In 1990, Swift world transport Ltd. adopted the supply chain management (SCM). This was adopted after realization that most food products require integration of many business processes, from the original supplier to the customer (Halldorsson, et al. 2003). The suppliers provide the company with products, services and important information that boost our business. SCM enables us to exchange information with other stakeholders regarding market fluctuation. After realizing the importance of information, we adapted the SCM to enable us access relevant information. This is made possible since all the companies in the supply chain help optimize the entire chain. The company can therefore plan its distribution activities better hence leading to customer satisfaction. In addition, incorporation of SCM leads to reduction of competition (Hines, 2004). This is because the competition is not from one company to the other but on supply chain and supply chain. The aim of supply chain management is to uphold customer satisfaction by using the available resources efficiently. It seeks to keep the demand and supply at equilibrium. Since many food products are perishable, it pays to liaise with producers to minimize bottlenecks. The products are obtained from farmers and suppliers at the lowest cost (Hines, 2004). Transporting is followed by distribution and finally delivering the products to customer markets. Conclusion One of the main challenges that Swift world transport Ltd faces is the presence of congestion in our road system. The causes of congestion come from higher requirement for mobility, which many times go beyond the facilities that support it. Other causes can be random events like accidents, which normally disrupts the flow of vehicles. Congestion is not only present on the roads, concentration of traffic is observed even on maritime transport. This is so common especially in terms of weight. Traffic concentration is causing many problems at the ports. In the past few decades, international trade has been experiencing higher growth than the global economy resulting in congestion at the ports. Congestion has the effect of delaying products on the road hence causing late Deliveries. Late deliveries in turn lead to loss if business opportunities and dissatisfied customers. Recommendation As a major stakeholder in the transport industry, we have joint hands with other like-minded firms to put pressure on government to build more road network. A transport policy that will provide solutions to congestion problems should be developed. This requires long term planning to build of more roads and ports in order to ease the congestion. States with port facility should apply for grants from the federal government in order to improve their inadequate facilities. These are the solutions to preventing the constant congestion.

Leonard Bernstein Essay -- essays research papers

Leonard Bernstein   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Leonard Bernstein was born in Lawrenceville, Massachusettes on August 25, 1918. He was the first born child of Samuel and Jennie Bernstein, who lived in Boston, but had gone to Lawrenceville to visit some relatives.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Bernstein's parents had little knowledge of, or interest in classical music. The only records Leonard remembers hearing on his family phonograph when he was a child were the popular hit songs of the day, such as â€Å" Barney Google† and â€Å"Oh by Jingo.† For the most part, Leonard Bernstein was an unhappy child. He said, â€Å" I was a miserable, terrified little child† (Musicians p.64). His family moved from town to town, during Bernstein's school days, not giving him a chance to make close friends or feel at home. Sadly, Bernstein's peers would make fun of and tease Bernstein. He was a very sickly child as he suffered from chronic asthma, rose fever, and hay fever. This pathetic child grew to be a very shy person.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Leonard always had a heart for music, even as a young boy. As an eight year old, one morning, when he was sitting in the synagogue, the religious music of the choir and organ overwhelmed him by it's beauty and caused him to burst into tears. When Leonard and his family would visit their friends, Leonard would sneak over to the piano and experiment. When he was eleven, his aunt sent her piano to his house for his family to keep for storage. â€Å"I made love to it right away† he recalled (Musicians p. 65). He could escape from all his frustrations and sadness by playing the piano. His parents didn't like the fact that he was always at the piano, they wanted him to concentrate on his school work. They thought of piano playing as a waste of time because it stood in the way of Leonard's learning his father's business, which they planned for him to eventually take over.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  At the age of ten, Leonard found a piano teacher who would give him lessons for a dollar a lesson. But that teacher soon moved away and Leonard found himself paying another piano teacher three dollars a lesson out of his allowance.
