Case Study on Social Work Theory Essay Example | Topics and Well Written Essays - 2000 words

Case Study on Social Work Theory - Essay Example Trevithick indicates that according to a study carried out by Birdwhistell â€Å"in a typical encounter involving two people, the actual spoken or verbal content is likely to carry only one third of the social meaning in any given encounter, whereas the non-verbal forms convey roughly two thirds of the meaning† (Trevithick, 1995). The methods used by social workers cover a large array of feelings, events, experiences and past traumas. It is essential for these methods to be compatible with social work values. There are some methods which are more suitable than others depending on the case. Planning the intervention is based on assessment of the current situation and precise evaluation of the best options for intervention. Social adjustment and enhancement of better social relationships is a result of the qualities and knowledge applied by the social workers and the willingness of the person to experience change. The task centred approach and the cognitive behavioural therapy are two methods that are extremely helpful in social work. They aid identifying the problems and finding a way to improve the situation of the person at present. In the case of John, who has spent most of his life in prison and has a history of alcohol misuse, it is essential to find the best methods to bring him back to society. It is important for the working methods to provide good understanding of the case and pave the way for a successful intervention afterwards. The task centred approach identifies the partnership with the service user which should be a central aspect of the practice. Partnership is characterized by respect for the service user’s point of view, better communication and recognition of the abilities of the service user to act (Doel and Marsh, 1992). Partnership is highly needed in John’s case since he has been isolated from society for a long time and needs to regain his confidence and feel secure. The essence of the task centred approach is

The effects of retail channel integration through the use of Essay

The effects of retail channel integration through the use of information technologies on Firm performance - Essay Example The article â€Å"The effects of retail channel integration through the use of information technologies on Firm performance† gives a vivid insight into the strategy that can be employed to integrate activities across multiple channels. This resolution lies in the use of information technology, a solution that offers a promising opportunity for most of the retail firms. This is because it is directed towards the enhancement of the relationship that exists between them and their customers. This is, in addition to improving the performance, of the firm in virtually all sectors. This can be tied to the fact that the goal of most firms is to improve people’s lives through their services and products. This is, in addition to, making profits that can enable them stay in the market for a long time. Throughout the article, the authors have focused on the constructive effects of information technology just to encourage those who are not into it to try out. They base this on the f act that by integrating both traditional and contemporary Channels within the retail industries efficiency and integration is improved. These effects, in one way or another, function to the act of the firm as well as customers who are among the key stake holders in any given firm. Another fact is that environment has a role to play because its dynamism is a sure moderating factor of the effects brought about by competence and modernization. All these attributes are aimed at inciting firms to employ this technique in both the retail and service sectors especially to those firms that have both physical and online operation. (Khosrowpou, 2006). Critique of article In the modern world of business, there has been increased shift towards the creation of positive environment that enhances productivity and efficiency. Thus, why many firms resolve to employ CRM software to provide a dependable platform for both customers and firms. This, in part, corresponds to the message in the article dis cussed. However, even though there is the persistence of adoption of technology, it should be noted that it is not for all companies to use it for some use â€Å"excel and outlook† in a stationary surroundings to uphold their information. In such a company, high technology such as use of CRM software is undoubtedly inappropriate. Therefore, the article has not emphasized on what companies are eligible to this high technology, for this is most prominent in growing businesses who are obliged to manage customer’s information with reliable software especially in the constantly changing business environment (Sambumurthy, 2003). However, the article has a valuable message concerning the ways in which businesses can manage change. This is because the modern day organizations have become complex, uncertain and more unpredictable, and, therefore, invention of ways of overcoming these challenges. Therefore, the advent of globalization demands that companies keep themselves up-to -date either through the latest technology or management fad (Lin-Bin et al, 2010). This vertical integration has numerous effects on the factors that lead to firm’s performance such as increasing firm size and reducing uncertainty. However, it has also its own

Hydrogen Peroxide As Additive For Diesel Fuel

Hydrogen Peroxide As Additive For Diesel Fuel CHAPTER 1 INTRODUCTION HEAT ENGINES A heat engine is a machine whose function is to produce mechanical energy and it does so by using heat energy that is released when combustion of fuel takes place. It is classified in two main types on the basis where the combustion takes place. 1. External combustion engines also called the E.C engines: Here, as name suggests, heat energy from fuel is extracted not inside the cylinder where mechanical movement is generated but outside at different setup from where it is carried along in any medium such as air, steam or gas and passed into setup where it can be used for generating mechanical movement. Examples of this type of engine are hot air engines, steam turbines, steam engines and closed cycle gas turbine. This kind of engine is mostly used in electric power generations, ships, and driving locomotives. 2. Internal combustion engines famously known as I.C engines: It can be easily understood from the name that heat energy of fuel is extracted inside the cylinder from where mechanical movement originates. I.C. ENGINES: Here the mechanical energy is generated by force on nozzle, blades of turbines or pistons. They are arranged in such a way that when fuel is burnt inside combustion chamber the gases so produced as result of this action having very high pressure and very high temperature creates a force that directly leads to the their movement. From the development point of view we can say that J.J.E Lenior was the one who developed the first practically okay engine in 1860 and after that many different version were experimented mostly having power of around 4.5 kw and efficiency near 5%. otto-langen is given credit for developing a four stroke cycle engine in 1876. The efficiency of engine was nearly around 11%. It worked on spark ignition system. In 1892 rudolf diesel came with the compression ignition engine which was more efficient than spark ignition engines. 1.2.1 Classification of I.C. Engines. CHAPTER 2 DIESEL ENGINE 2.1 INTRODUCTION It is an internal combustion heat engine where heat energy, produced by spraying fuel on compressed air having a high temperature that is above the self-ignition temperature of fuel inside the cylinder, is converted in to mechanical work. Piston is arranged inside the cylinder that produces this mechanical work in response to combustion and expansion of air inside the cylinder. Diesel engine works on both 2 stroke and 4 stroke cycle. The main difference between diesel and petrol engine is that diesel works on the concept of constant pressure heat addition while petrol works on the concept of constant volume heat addition. For an engine to work on constant pressure heat addition concept it needs fuel which has low self-ignition temperature. And the fact that only air is compressed inside the cylinder is the reason for high compression ratio of diesel engine. They lie in the range of 14-22. 2.2 WORKING The four important processes of a diesel engine are intake of air, compression of the air to temperature that is above the self-ignition temperature of fuel, combustion inside the cylinder by spraying fuel on the compressed air and finally letting out the gases from cylinder after combustion. These four processes are repeated in cycle to make the engine run continuously. These four processes can be done with two strokes of piston (one revolution of crankshaft) or four strokes of the piston (two revolution of crankshaft). Lets understand the four stroke processes briefly because we are going to perform experiment on 4-stroke engine. During first stroke piston moves down creating space for air to come in. now when piston moves upward it compress air within the cylinder. When piston reaches at the top fuel is sprayed in the cylinder. This leads to combustion and downward movement of piston. After reaching bottom piston moves upward removing the exhaust gas from cylinder. And again when piston moves down fresh air is taken in cylinder and processes goes on. The up and down movement (linear motion) of piston is converted in to rotary motion through crankshaft which is connected to the piston. Please refer to the diagram below. 2.3 FUEL INJECTION The injection of fuel to the cylinder is very critical processes. If done with accurate timing and injection pressure it can lead to enhanced performance of the engine. The injection pressure given to the fuel by injector is typically 7â‚ ¬Ã‚ ª106 to 7â‚ ¬Ã‚ ª107 pa. The accurate time for fuel injection is when piston is about to reach the top of cylinder. When fuel is injected inside it is partly combusted as constant volume and then as piston moves down the remaining part is combusted as pressure constant processes. 2.4 PROS AND CONS OF DIESEL ENGINE The diesel engine is far more superior to the gasoline engine in terms of efficiency. They do not make noise and are very low on maintenance requirement when compared to gasoline engines. Its reliability and ruggedness is more. As fuel leads to combustion due to low self-ignition temperature no spark plugs are required which leads to lower cost of maintaining. Cost of fuel is lower, around 30% to 40% than gas engines. Another major advantage it gives over gasoline engine is by producing low waste in exhaust and cooling Major disadvantages of diesel engine are its high weight to horsepower ratio and difficulty to make them start when they are in cold weather area. CHAPTER 3 DIESEL FUEL AND ADDITIVES Any liquid that can be utilized to operate diesel engine is called as diesel fuel. Mainly derived from following four sources. Diesel fuel has been divided into three major groups by ASTM (The American society for testing and materials), which depends on the various uses of diesel engines. They are: No. 1-D for frequent load and speed changing engines. No. 2-D for engine with constant speed but high loads. No. 3-D for low and medium speed engines that operate under sustained loads. 3.1 DESIRED QUALITIES OF DIESEL FUEL Keeping in mind the functioning of diesel engine that are few important and critical qualities that a liquid must have to serve as diesel fuel. They are: 3.2 STANDARD SPECIFICATION OF DIESEL FUEL Depending upon intention of use, diesel fuel is available in various grades. Diesel fuel is a mixture of different crude oil derived substances, all with their own physical and chemical properties, such as paraffins, isoparaffins, napthenes, olefins and aromatic hydrocarbons. Diesel fuel has to work in various kinds of engine types, having difference in conditions of operation and cycles of duty, and range of technology of fuel system, temperatures of engine and pressures of fuel system. It must suit a wide range of different climates. The balanced properties of each grade of diesel fuel are important to give good performance over an extremely various situation .The most common in use guidelines for diesel fuel are given by ASTM International. ASTM specifications are created after taking into consideration, based on the wide range of experience and cooperativeness of diesel fuels producer, diesel engines manufacturer and fuel systems (and users of both), and other important officials like state fuel quality regulators. 3.3 IMPORTANT PROPERTIES OF FUEL 3.4 DIFFERENT TYPES AND FUNCTIONS OF ADDITIVES Diesel fuel properties are met and maintained by petroleum industry by taking the use of number of commercial diesel fuel additives. Fuel components and additives are different from each other. Firstly Fuel Components are hydrocarbon classes like aromatic, iso-paraffin and naphthene. They basically sum up the volume of the fuel. While Additives are added to fuel in at very less amounts, generally at the ppm level, and is of no significance fuel volume. There are different types of additives that are used to improve fuel in different ways and to overcome different problems. Following table give different types of additives and their functions. Table showing different types and function of additives. Type of Additive Function Cetane number improver Improves ignition quality by raising cetane number, better starts, reduces white smoke Lubricity improvers Improves lubricity, better injector pump lubrication Antioxidants Extend storage life, inhibit oxidation, reduce gum and precipitate formation Stabilizers Inhibit oxidation extend storage life Metal deactivators Deactivate copper compounds in fuel, thereby promoting longer storage life Pour point depressants Low temperature operability, improve cold flow properties Smoke suppressants Promote more complete combustion reduce exhaust smoke Rust preventers Reduce formation of rust in fuel systems storage tanks De-emulsifiers Used to increase the rate of water separation from the fuel CHAPTER 4 HYDROGEN PEROXIDE Having very high oxidizing capability Hydrogen peroxide (h2o2) is one of the strongest reactive oxidizer that exists. Naturally, it is synthesized as the by-product of oxidative metabolism in nearly all-living organisms. It is mainly used as a propellant in rocketry, as bleach, as an antiseptic and as an oxidizer. It has IUPAC name of Di-hydrogen dioxide and is also known as Dioxidane. Molecular diagram of hydrogen peroxide 4.1 IMPORTANT PROPERTIES OF H2O2: 1. Hydrogen peroxide has a Molar mass of 34.0147 g/mol 2. It appears colorless in solution and otherwise has a very light blue color. 3. H2O2 has density of 1.463 g/cm3 4. Melting point of -.43 oc. and boiling point of 150.2 oc. 5. It has more viscosity than h2o. 6.It has calorific value of 2700 kJ/kg. 7. Has dipole moment of 2.13 debye and refractive index of 1.33 (same as that of water) 8. It has specific heat capacity of 1.267 J/kg (gas) and of 2.619 J/kg (liquid) 4.2 HYDROGEN PEROXIDE AS AN ADDITIVE: One important reaction of hydrogen peroxide is its spontaneous exothermic decomposition into oxygen and water. The reactions is: 2 H2O2  ® 2 H2O + O2 It has: 1. Standard enthalpy of reaction of -98.4 kJ/mol 2. Gibbs free energy of -118.7 kJ/mol 3. Change of entropy of 71 J/mol Because of this property of hydrogen peroxide it is used as propellant in rocket. Here high-test peroxide (hydrogen peroxide with concentration of around 90%) is used. The H2O2 decomposes into steam and oxygen. According to me same concept can be applied to diesel engine as well. Where adding small amount of hydrogen peroxide to the diesel fuel can improve ignition of diesel fuel inside combustion chamber by providing additional oxygen and energy when it decomposes. And steam thus produced will easily move out along the exhaust gases. CHAPTER 5 EXPERIMENT PERFORMED 5.1 OBJECTIVE: To conduct experiment using 4 stroke, 2 cylinder diesel engine to study the effects of addition of hydrogen peroxide to the diesel fuel. And compare the performance of three different sample fuel where the first one is 100% diesel, second is 95% diesel + 5% hydrogen peroxide and third is 90% diesel + 10% hydrogen peroxide. 5.2 AIM: To calculate following parameters for three fuel samples: Brake power (BP). Brake mean effective pressure (Pbm) Fuel consumed (Qf) Heat energy produced by fuel (Hf) Brake specific fuel consumption (BSFC) Brake thermal efficiency ( Ã‚ ¨bt) Air fuel ratio (A/F) 5.3 EXPERIMENTAL SETUP: Diesel engine has two cylinders and is four stroke, water-cooled engine. Dynamometer that is a rope brake type has been provided with loading sensors. Different rota-meters has been arranged to calculate flow of water to calorimeter of exhaust gas and to the engine jacket. Setup is equipped with temperature sensors, air tank and fuel tank for supply. Software has been programmed to collect data. It provides experiment performer to log-in data and store and print them. This software allows tabulation and comparison of data collected. Now lets discuss about the dynamometer mentioned above. It has brake drum, load cell, and arrangement of cooling down water. It is so coupled with the shat of the engine that load can be changed using rotation of wheel that increases the tension of the drum. Another important part of the setup is facility provided to measure the heat energy gone along with exhaust gases. Calorific measuring meter is equipped with jacket of the cooling water and shell that is in central with baffles. Water is made to flow against in indirect contact with gas that comes from exhaust and there is a rota-meter and valve to control the rate of flow of this water. So using heat can be measured that is going out as a waste with gases that comes from exhaust. There also is a provision made for getting p-v and p- Ã¢â‚¬Ëœ graphs. These works based on the sensors. Sensors that are stored in combustion chamber and aligned along the shaft that gives the output motion that has been produced by engine. These sensors provide the software the data of different pressure and angle of crank. And then we directly get graphs on the computer. But sadly these sensors have been damaged and cannot be used. So we are not able to get these graphs which are essential part of performance analysis. 5.4 EXPERIMENTAL PROCEDURE: First of all three different samples of fuels are made. Sample 1 is pure diesel. Sample 2 is 5% hydrogen peroxide and 95% diesel. Sample 3 is 10% hydrogen peroxide and 90% diesel. All the pre-checks of the engine are conducted such as SAE 20w40 oil is filled in the oil sump up to needed level using a stick that is made specially for this purpose, data cable is connecting unit of interfering with the computer, flow of water is set accordingly through rota-meters. Filling of the fuel sample in the fuel tank. Starting engine with the help of lever that is for decompressing. Lifting this lever while turning flywheel at high speed taking use of handle leads to smooth starting of engine. Run the engine for like say 2 min before any thing to be done because it needs time to stabilization. Now loading of the diesel engine is done with help of dynamometer. Here we will try and set four different loads for a sample of fuel. Firstly zero kg then eight kg after that 16 kg and finally 24 kg. Readings are noted down or you may say logged in the computer for every load and saved. After completion of the experiment for fuel 1 same procedure is followed for other two samples. After the readings and information of all samples are collected stop the engine only after reducing load on engine. Finally close the supply of water that is used for cooling and stop the fuel supply. 5.5 IMPORTANT SPECIFICATIONS OF ENGINE: 14 horse power engine Diameter of bore is 87.5 mm Length of stroke is 110 mm Length of arm acting on dynamometer is 0.165m Density of air is taken as 1.21 kg/m3 Gravitational acceleration is 9.81 m/s2 Surface area of piston is 6.01*10-3 m2 Volume swept by cylinder per second is .0165 m3/sec 5.6 FORMULAE USED: Please note formulae have been written after calculating all constant and known values as specific numerical constant so as to get clear picture of what and how different variables affect the values of performance indicators. And also that following set of formula apply for sample 1 only and similarly formulae for sample 2 and 3 were calculated separately. Brake-power (in kw): m is mass of load acting on dynamometer (kg) N is revolution per minute of shaft Break mean effective pressure (in N/m2): Fuel consumed by engine (in kg/s): X is volume of fuel consumed (in ml) T is time taken to consume X ml of fuel (in seconds) Air fuel ratio: Qa is flow rate of air intake by engine (in m3/s) Brake specific fuel consumption (in kg/kw-s): Heat supplied by fuel (in kw): Brake thermal efficiency (in %): Volumetric efficiency (in %): 5.8 ANALYSIS AND COMPARISION OF PERFORMANCE: GRAPH: LOAD VS BRAKE POWER From above graph we can say that all the 3 samples of fuel are able to give same brake power output. This helps us to confirm that 2 experimental fuel are able to provide same output as that provided by original fuel. GRAPH: LOAD VS BSFC From the graph we can observe that sample 2 has higher BSFC then other 2 samples at low loads. But as the load is increased sample 2 has slightly lower BSFC than other two samples. While sample 3 gives you lower BSFC at low loads and same BSFC as the sample 1 at higher loads. GRAPH: LOAD VS BRAKE THERMAL EFFICIENCY From graph above, it is clearly visible that sample 2 and sample 3 provides higher efficiency than the original sample 1. And it is also important to note that there is not much vast difference between efficiency of sample 1 and sample 2 CHAPTER 6 CONCLUSION The experiment was performed on the 4-stroke, vertical, 2-cylinder diesel engine. It was maintained at constant rpm of 1498 and 50 ml of fuel was consumed at each load. Four load conditions were decided to perform experiment on 3 samples of fuel keeping in mind the capability of engine. The 4 conditions were 0, 8, 16, and 24 kg. The positives that we can take from the experiment performed are that we are able to produce same output result in terms of output power at output shaft though the heating value of sample fuel 2 and 3 are lower than that of sample 1. This is the reason we are able to show increase in brake thermal efficiency obtained by sample fuel 2 and 3 than that obtained by sample 1. But the most important conclusion that I think from the experiment is that there is slight decrease in BSFC of sample fuel 2 at high load. Due to limitation of experimental conditions we cannot check the result for load above 25 kg. I believe that this result has originated from the fact that hydrogen peroxide provides that additional oxygen and energy when it decomposes exothermically to give steam and oxygen. The thing that hampers the proposition of hydrogen peroxide as an additive for diesel fuel is its storage problem. A research is needed on the feasibility of storing hydrogen peroxide separately than the diesel in engine and spraying it through different injection system than that of diesel because there could be possibility when hydrogen peroxide in the fuel tank it may decompose itself without aid of compression temperature in combustion chamber in long-term storage. The cost factor also needed to be taken into account. The other few things that are kind of inconclusive and needs further research on them are how does steam produced by decomposition reaction affects the engine on long run and what amount of hydrogen peroxide is optimum for the engine.

The Purpose of Education Essay -- Education

What is the purpose of education? What do we seek from it? How does it better our lives? What is the role of public schools? These are all important questions, but first I am going to give a brief summary of the text by Timothy McMannon entitled The Public Purpose of Education and Schooling. McMannon gives the reader plenty of reasons for why we need education and how it helps us and our society; he starts by explaining that in past cultures schooling was not done in a formal school but in â€Å"the community, the family, and the church.† (McMannon 1) Some cultures even believed that education was something that took a lifetime. The essay then progresses into explaining how education has evolved through the centuries into what it is today and why it has become what it is. Everyone has their own take on what they believe education is and should be. Your parents could think of it as a day care facility until you get to high school and then they might think of it as a place to earn a degree and soon move out. Your grandparents might think of it as a place where you go to learn things that you aren’t going to need in life because they never did. Political leaders may think of it as an economical advantage over another country. The list goes on, but as a student, I believe that there are many purposes of education; it is more than one thing, but many things that combine into what education really is. One role of public schools is to promote the principles and standards of our society, which have been all but forgotten. Today we assume that school is a place where we go to learn history and mathematics, but it is much more than that. Schooling teaches us what our leaders are too busy to explain. McMannon explained in his essay how we ... ..., why would you continue with it? In part, â€Å"education must be practical.† (McMannon 8) Without practicality, there would be no point in receiving an education. Works Cited Fulghum, Robert.

Unit 7 Perds Childcare

P7 Task 2 Write a short report on how you’re setting promotes positive images of children and reflects a diverse society. Include in your report: P7. 5 Explain how the setting promotes positive images of children and reflects a diverse society An image which presents a mixture of cultural backgrounds coming together such as an Asian and black girls playing together, this will show children that they are able to play with different races and therefore a positive image.Promoting a positive image is important especially in settings which work closely with children because once a child enters a setting they take interest in the images and objects around them, and by seeing images that celebrates different cultures and background will teach the child and allow them to see how others live and play together. To prompting positive image my setting takes pictures of the children interacting with each other through play and work. Once the child and other children see this on display the y repeat the same thing because of the positive effect it has had on them.This helps to build children’s self-esteem through play because now they will be able to interact with a range of different children and create a wider friendship group. It is important for settings such as nurseries to reflect on the way they promote positive images because the images that a child sees at an early age can influence behaviour. According to public opinion journalist Walter Lippman â€Å"the little picture we carry around in our heads†. Children will then start to relate life to that image the now have in their heads.Nurseries should incorporate images around the world so that children can have a better understanding of those around them, also that the children don't assume that the one image that they setting has is the right image for them or the characters that they see on Walt Disney such as Cinderella, sleeping beauty and snow white is the appropriate way for a young lady to d ress or behave as a damsel in distress. Walt Disney presents young ladies as sexual beings that cannot help themselves but wait for that handsome prince to come and save them.Girls are passed images like this from a young age with creates that stereotype image in their head which can affect their behaviour the way they think and act as they grow through their adolescents and adult years. Creating a diverse society by welcoming every family, regardless of their sexual orientation, family status, religion, race and ability will allow the every child and family member to feel welcome in that setting. This also allows children from an early age to understand that every child is an individual and has their own ability.This is why we have a welcome poster which has a number of ways in which parents and staff welcome each other, this encourages and shows that the setting is welcoming. P7. 6 Describe a resource which uses positive images The recent Christmas advert by M, included a child wi th Down syndrome, this images allows other children with Down syndrome and their families to see that they too can do what is considered â€Å"normal†, this image was then displayed as part of a mixture of images at my setting.An image which presents a mix of races in a family photo sends the message to children that the colour of a person skin doesn’t determine who or can be in their family. The media is a strong resource which in many ways controls the child's sub-conscious minds. Through media we are now able to see a more positive and realistic image of the world we live in. This summer was the 2012 Paralympics, showed on television live for the first time, this showed people who were deemed disabled to overcome the impossible in their lives.The Paralympics showed people without limbs, running races, swimming laps and the visually impaired playing football. The media holds many connection to what humans see and keep in their minds, what newspapers print out, what s hows advertise and how all add to the positive images we see today. At many of the settings I have worked in have book corners or library's, containing a number of books from based on different cultural background such as the well-known story ‘handa's surprise' this book shows a African girl planning to surprise her friend, this story shows children how to be kind, and nice. P7. Evaluate briefly your learning from finding information for this report For this report I researched the many different ways in which we see images, whether it be a positive or negative image. I learned about the effects on a child from the images they see in their settings, on the streets and in their homes. This report has made me to understand the effects of Barbie dolls and action figures have on a child's sub-conscious mind. Images of young vulnerable beautiful ladies who find themselves in some sort of danger and the only way to get help are through a strong handsome man, these images presented t ime and time again by Disney.But images by presented by Dream works, where the woman are able to defend for themselves, male and female are equals and they fight crime together such as Shrek and princess Fiona. This image shows both girls and boys that they are equal also that not all girls are â€Å"weak† and â€Å"vulnerable†, boys don’t have to be the â€Å"hero†. I had not realised how wide-spread gender stereotyping is. Properly because I am so used to seeing it all the time, I did not really question it or the influences pictures have on us.Images are seen through many resources such as the media which is a massive impact, what we see on bulletin board, adverts, posters in stores and parents. From this short report I was able to understand that an image might be positive or negative just by what a person says or the Picture portrays. A simple image e. g. a family with mixed races from around the world, a simple comment such as â€Å"we are familyâ €  could slowly show a child that diversity is a good thing, but if the comment was â€Å"that aren’t right, they don’t look the same†, will create in the child’s mind that every member of a family has too look the same.I think that in future when I see a new form of attraction whether through the media, books or toys that I will look closely at the aims that other I. e. parents and young children may not see. Task 3 P7. 8 Describe TWO (2) examples of activities or experiences which encourage children’s awareness of their own and other’s safety One day at my setting I witnessed a child running with scissors in his hand, I stopped the child and told the practitioner; once I told the practitioner and she immediately call all the children to the carpet to talk to them.She asked them if they knew why she called them all to the carpet, many thought it were to practice for their school play, and others thought it was a game. The practitioner th en explained to children that they are sitting on the carpet because of what she was told that someone was running with scissors. She then asked the children if scissors are dangerous. The children replied in simultaneous voice, â€Å"yes†, she then asked should we through or run with scissors in our hands? The children replied â€Å"no† and where should the scissors stay when we want to move around the room? On the table†. The practitioner then explained to the children that if these rule where broken that someone could get seriously hurt. At my last lesson I was able to take part in going a school trip to the natural museum with the nursery class. The day before the trip I helped the practitioners in the class to set up a miniature road course, by placing red, yellow and green cones on either side of the playground. The three cones represented the traffic light; I also placed images of the red and green man on the floor on the opposite side of the playground.My job was to control the red/green men, as the practitioners explained to the children, the instruction and the role of each individual sign and their jobs we began the activity. I watched the practitioner get the children in to peers as they will be the next day, once the children were ready and settled the children where walked around the pretend road side, once they came across me at the traffic lights I Held over my head the red man as the practitioner as the children what the symbol meant. She also explained in detail why it is dangerous to cross when this symbol is show.Once the practitioner had finished explaining about the red man, could out the traffic light colours in descending order then swopped the red man for the green man. The practitioner then repeated the same explanation by about the green man, after she has explained she lead the children across safely. P7. 9 Reflect on the effectiveness of the activities or experiences in practice My first experience was not a pla nned activity but was effective in its own way; it was affective in a way whereby the practitioner asked the children questions to identify what they knew about running in the class with sharp objects like scissors.From asking them questions the practitioner and my self was able to see that the children did know the rules but needed to be reminded. I think that if the class had posters of the rules in the class it would remind the children. In the future we can get the children to create their own posters on road safety. I feel that my second activity was very effective because it created a pretend scenario for the children which they will encounter the next day. This activity explained the different symbols, why they are there to keep us safe.This activity also taught the children what to look out for and how to follow the road signs. By the practitioner asking the children questions she was able to notice who has started to understand the signs and who needs more explanations. If I was to repeat this activity, I would allow the children to pick which symbol or sign they think it correct for at point in time this is because it evolves the children and allows myself and other practitioners to see what the child may already know or has picked up.
