Lesson Plan Title: Alexander, Who Used to Be Rich Last Sunday: Understanding Opportunity Costs Grade Level:2, 3, or 6th Duration: three 50-minute class periods Student Goal: To understand that there is an opportunity cost to every economic decision and that these costs come as a result of limited resources. Student Objectives Students will: †¢ Identify "opportunity costs" in the story and in their own lives. †¢ Create an opportunity costs bar graph as a whole class. †¢ Complete a table of personal spending and savings information. †¢ Write an original story about how they spent and saved their allowance and what they gave up or their "opportunity costs" in order to reach their goals. Materials: †¢ a copy of Alexander, Who Used to Be Rich Last Sunday, by Judith Viorst †¢ chart paper †¢ markers †¢ overhead projector †¢ transparency †¢ student handout: How I Spent & Saved My Allowance (included). This was provided by the teacher in which I was doing my participant observations with. Set Up and Prepare: 1. Use the book Alexander, Who Used to Be Rich Last Sunday, by Judith Viorst. 2. Write the definition of the term "opportunity cost" on a sheet of chart paper and display for the class: Opportunity Cost: what you give up when you decide to do or buy something 3. Draw a bar graph on a transparency. Write the title "Opportunity Costs for a College Education" across the top. Label the horizontal axis "Opportunity Costs." Label the vertical axis "Number of Students." 4. Print out copies of the student handout "How I Spent & Saved My Money" for each student to take home. Directions: PART I: Step 1: Share with students a story about a time when you did not buy something you really wanted so that you could use or save the money for something more important. For example, maybe you didn't go on a vacation so you could save the money for a car you need to buy. Explain that what you gave up is called an "opportunity cost." Direct students' attention to the definition of "opportunity cost" displayed on the chart paper. Step 2: Ask students to share stories from their own lives in which they gave up something to get something else, or to save for something else that they want more. Have them identify their opportunity costs. Ask studen... ... †¢ How much does Alexander have after he buys the gum? ($0.85); after he loses a bet to his mother? ($0.70); after he rents Eddie's snake? ($0.58); after his father fines him for saying naughty words ($0.48); after flushing pennies down the toilet and dropping a nickel through a crack? ($0.40); after paying for Anthony's chocolate bar? ($0.29); after pennies disappear in Nick's trick ($0.25); after paying his father for kicking his brother? ($0.20); after buying things at a garage sale ($0.00). Set Up Shop/ Learning Center: Students set up a shop and role play the parts of customer and shopkeeper, making economic decisions along the way. Have them draw pictures or use manipulatives for the items they are selling in the store. Allow them to determine prices and tag each item. Then give all students the opportunity to be a customer and the shopkeeper. Provide customers with a limited amount of play money to spend in the store. They will need to budget their money so that they can afford all they need to buy. Using play money too, the shopkeepers sharpen their math skills as they make change for the customers.

Reaching Your Potential
After I read this article I fond out that managing yourself is a good way to be successful. There are some strategies of how to achieve higher levels of success, such as knowing yourself, excelling at critical tasks and demonstrating character and leadership. The purpose is to clear understand who you are and what your dream is. There is one strategies really touched me is that knowing your self from strengths and weakness can help you to achieve your dream or goal. First, knowing yourself is telling you to understand what are your strengths and weaknesses when you start your career. Some people can easily tell what are their strengths, but hard to defined the weakness. Talking to other people who knows you is a good way to get the answer. After finding the weakness and strength, the next thing is to ask yourself about what is your dream work and what do you enjoy doing? Then keep your strength and face your weakness in order to reach your full potential. I do agree this strategy and it helps a lot, I still remember when I started working, I wasn’t good at communication at first. However, my job required me to communicate with different manufactures, so I need to negotiate with different departments and sometimes I am asked to go to the factory to see the quality of samples. It requires a certain level of communication skills. In order to practice my communication skill, I try to write down my points before conversations. After a lot of time practice, I can clearly state my point of view. I faced my weakness in order to do well with my job. I think those practices not only improve my working ability but also having a good effect even up to now. Secondly, Excelling at critical tasks is to know how to develop your skills and how to distribute times after a critical business meeting. In order to reach your potential, it requires introspection and certain proactive behaviors. This strategy reminds me of my previews manager when I working in a French fashion company. She is good at using spare time to find useful information. In my memory, she always came to office half hour earlier and collected some latest news from fashion newspaper and websites, and prepared work to each designer. This is a good way to distribute times and practice the skill of colleting useful information. Last but not least is demonstrating character and leadership, a leader is a good decision maker and benefits the organization’s overall performance, and also they need to speak up and make better choices. I think leadership is a major element in management field, and better leadership can make company better organized. In conclusion, the advice for you to reaching your potential is to identify your dream, develop the skills after finding your weakness, and exhibit character and leadership.

A Doll’s House Essay
Perspective of A Doll’s House Henrik Ibsen’s A Doll’s House uses emotional conversations to depict a family living in false emotional circumstances and having to come to terms with reality. The title A Doll’s House describes the facade of a family living in a nice house. The platitude â€Å"All that glitters is not gold†means that not everything that looks good on the outside is not good on the inside, like a doll’s house. In the first part of the play, Nora’s old friend from school, Mrs. Linde arrives impromptu. Nora is very fast to describe to her what a good life she has; â€Å"So you are quite alone.How dreadfully sad that must be. I have three lovely children. You cannot see them just now, for they are out with their nurse†(7). This shows how important it is to Nora to keep up her facade of having a nice home and a good life. It’s also makes a distance between the two women's lives, even if Mrs. Linde tells Nora ab out her poor family situation, Nora still brags. During the conversation, Nora tells Mrs. Linde about her secret; that she has borrowed money from Krogstad, one of the bankers in town, to help her husband Torvald a long time ago.Torvald does not know anything about the loan and Mrs. Linde is surprised about it and she thinks Nora should tell him about it. Nora answers; â€Å"†¦ And besides, how painful and humiliating it would be for Torvald, with his manly independence, to know that he owed me anything! It would upset our mutual relations altogether; our beautiful happy home would no longer be what it is now†(12). This reflects the old sight of male and female position in the home or relation; the man is the one who should be responsible for the income and be independent. The female part is the opposite.The last sentence from Nora, demonstrates once again how important it is for her that her life looks perfect from the viewer’s sight. Nora is in a very hard situ ation with Krogstad because of the loan she took a long time ago. Krogstad behaves insipid against Nora in the middle of the play, when he threats her to tell Torvald about the loan. She talks to Dr. Rank, an old friend of the family, and she is very close to betraying her big secret, but instead she just informs him; â€Å"You can do nothing for me now. Besides I really don’t need any help at all. You will find that the whole thing is merely fancy on my part.It really is so-of course it is! †(41). From this we learn that Nora changes her sight of her self. She acts very clearly to Dr. Rank for many reasons, for example to get rid of Dr. Rank’s curiosity and also to convince her self that she has done the right thing and that everything is going to be fine. It also shows one of her first steps into her independence. In the end of the play, Nora realizes that her life is not real, is not perfect, is not fantastic; it is just like a dream story from outside like she always wanted her life to be – but she is not satisfied.Nora decides to tell Torvald about how she feels and she forces him to talk with her seriously; â€Å"I say that we have never sat down in earnest together to try to get at the bottom of anything. †Torvald answers â€Å"But, dearest Nora, would it have been any good to you? †(66). It looks like Torvald doesn’t think Nora has her own thoughts, or her own willing. He does not listen to her or maybe he does not want to listen to her. Nora continues to inform Torvald about her feelings, about how he and her father have made a big sin against her. â€Å"It is your fault that I have made nothing of my life†(66).Nora is much older now then she was when she first met Torvald, and she has changed during the years. Both of them play their roles very well and it is not only Torvald’s fault that she has not been able to do something of her life. When it comes to someone’s life, it is very much up to the person herself. Nora tells Torvald that she has never been standing on her own feet, â€Å"I have been your doll wife, just as at home I was Papa’s doll child; and here the children have been my dolls. I thought it great fun when you played with me, just as they thought it was great fun when I played with them.That is what our marriage has been, Torvald†(67). Ibsen describes how Nora gets an insight about which kind of life she lives. The image pattern of Nora shows a change comparing of the beginning of the book when she brags in front of people. The three children stand for happiness but Nora does not seem to have a close and genuine relationship to them. It is just a scene. Nora comes to a point in her life when she understands that she lives an unreal life and she has to do something about it. Ibsen shows that she is able to take the step out of the marriage like an independent person.Everyone thinks she lives her life like a doll in a perfect home. Ibsen’s choice of title is both good and ironic; good because it brings thoughts to the perfect family-life, and ironic because the play tells about how the inside of the house; the family, the marriage, the relations etc. , struggles with a lot of problems in contrast to the facade. One of Ibsen’s messages about marriage and family is to manage to be happy together, everyone has to take care and understand herself before she can take care of others. When a person is independent and safe on her own, she is able to love and take care of her true love and family.

Hess Law of Heat Summation Essay Example
Hess Law of Heat Summation Essay Example Hess Law of Heat Summation Essay Hess Law of Heat Summation Essay Hess Law of Heat Summation Hess Law states that: The enthalpy change for any reaction depends on the products and reactants and is independent of the pathway or the number of steps between the reactant and product.

Explore Antarcticas Hidden Lake Vostok
Explore Antarcticas Hidden Lake Vostok One of the largest lakes on planet Earth is an extreme environment hidden beneath a thick glacier near the South Pole. Its called Lake Vostok, buried beneath nearly four kilometers of ice on Antarctica. This frigid environment has been hidden from sunlight and Earths atmosphere for millions of years. From that description, it sounds like the lake would be an icy trap devoid of life. Yet, despite its hidden location and terribly inhospitable environment, Lake Vostok teems with thousands of unique organisms. They range from tiny microbes to fungi and bacteria, making Lake Vostok a fascinating case study in how life survives in hostile temperatures and high pressure. Finding Lake Vostok The existence of this sub-glacial lake took the world by surprise. It was first found by an aerial photographer from Russia who noticed a large smooth impression near the South Pole in East Antarctica. Followup radar scans in the 1990s confirmed that something was buried under the ice. The newly discovered lake turned out to be quite large: 230 kilometers (143 miles long) and 50 km (31 miles) wide. From its surface to the bottom, it is 800 meters (2,600) feet deep, buried under miles of ice. Lake Vostok and Its Water There are no subterranean or sub-glacial rivers feeding Lake Vostok. Scientists have determined that its sole source of water is melted ice from the ice sheet that hides the lake. Theres also no way for its water to escape, making Vostok a breeding ground for underwater life. Advanced mapping of the lake, using remote sensing instruments, radar, and other geologic research tools, show that the lake sits on a ridge, which may be harboring heat in a hydrothermal vent system. That geothermal heat (generated by molten rock beneath the surface) and the pressure of the ice on top of the lake keep the water at a constant temperature. The Zoology of Lake Vostok When Russian scientists drilled cores of ice out from above the lake to study the gases and ices laid down during different periods of Earths climate, they brought samples of frozen lake water up for study. Thats when the life forms of Lake Vostok were first discovered. The fact that these organisms exist in the lake water, which, at -3 ° C, is somehow not frozen solid, raises questions about the environment in, around, and under the lake. How do these organisms survive in these temperatures? Why hasnt the lake frozen over? Scientists have now studied the lakes water for decades. In the 1990s, they began to find microbes there, along with other types of miniature life, including fungi (mushroom-type life), eukaryotes (the first organisms with true nuclei), and assorted multicellular life. Now, it appears that more than 3,500 species live in the lakes water, in its slushy surface, and in its frozen muddy bottom. Without sunlight, Lake Vostoks living community of organisms (called extremophiles, because they thrive in extreme conditions), rely on chemicals in rocks and heat from the geothermal systems to survive. This isnt terribly different from other such life forms found elsewhere on Earth. In fact, planetary scientists suspect that such organisms could thrive very easily in extreme conditions on icy worlds in the solar system. The DNA of Lake Vostoks Life Advanced DNA studies of the Vostokians indicate that these extremophiles are typical of both freshwater and saltwater environments and they somehow find a way to live in the cold waters. Interestingly, while the Vostok life forms are thriving on chemical food, they themselves are identical to bacteria that live inside of fish, lobsters, crabs, and some types of worms. So, while the Lake Vostok life forms may be isolated now, they are clearly connected to other forms of life on Earth. They also make a good population of organisms to study, as scientists ponder whether or not similar life exists elsewhere in the solar system, particularly in the oceans beneath the icy surface of Jupiters moon, Europa. Lake Vostok is named for Vostok Station, commemorating a Russian sloop used by Admiral Fabian von Bellingshausen, who sailed on voyages to discover Antartica. The word means east in Russian. Since its discovery, scientists have been surveying the under-ice landscape of the lake and the surrounding region. Two more lakes have been found, and that now raises the question about connections between these otherwise-hidden bodies of water. In addition, scientists are still debating the history of the lake, which appears to have formed at least 15 million years ago and was covered over by thick blankets of ice. The surface of Antarctica above the lake routinely experiences very cold weather, with temperatures dipping down to -89 ° C. The biology of the lake continues to be a major source of research, with scientists in the U.S., Russia, and Europe, studying the water and its organisms closely to understand their evolutionary and biological processes. Continued drilling poses a risk to the ecosystem of the lake since contaminants such as antifreeze will harm the organisms of the lake. Several alternatives are being examined, including hot-water drilling, which may be somewhat safer, but it still poses a danger to lake life.

There are signs that the current economic situation is improving Essay
There are signs that the current economic situation is improving - Essay Example HRM is also entrusted with the tasks of ensuring that a suitable working environment is developed in organisations. Moreover, it also ensures that a harmonious and a better relationship is developed amid employees and management of organisations. The role of HRM can be viewed to get affected due to influences with respect to internal along with external environment. In this regard, the internal factors include organisational culture and climate. Organisational culture is based on various factors including values, beliefs along with ethnicity of employees. Organisational climate depends on leadership styles, communication and human resource (HR) policies. On the other hand, external factors comprise economic conditions, demographics and labour market conditions. Economic conditions entail availability of financial resources or materials and demand along with supply of products and/or services. Labour market implies the availability of labour forces to be recruited. Demographics state the features of the workforces to be recruited which include education level, marital status and age. In this context, the economic conditions are determined as the major element affecting the aspect of HRM in maintaining the performance of business organisations. This can be owing to the reason that the economic conditions pose several threats to certain significant factors that include employment rate and productivity (Pearson Canada Inc., 2013). It can be apparently observed that the global economy has been under economic recession from the period 2009, affecting business operations on a global context. However, the commencement of the year 2011 has been identified to reveal signs of improvement in the global economic conditions with increased demand and sales of products and/or services. Additionally, the rate of employment has declined by a certain extent. Moreover, there are certain other factors depicting the reviving conditions of the global economic conditions that include profit margin, increased factory productions and better job opportunities (Pearson Canada Inc., 2013). In this respect, the essay intends to discuss about the impact of improving economic conditions imposed on the policies along with other strategic aspects of HRM within organisations. Review of Literature Improving Economic Situations According to Monica (2012), the economic conditions have been observed to improve by a certain extent in a slow and a steady manner after the recession period. It can be viewed in this similar concern that the spending of consumers in the worldwide market segments have increased by a substantial amount due to greater flow of money in the economy. Additionally, operations of business organisations have increased on a global context with better trading activities and sales of products and/or services. Monica (2012) noted that flow of investments has augmented with the rise of the trends of globalisation. Moreover, the rate of inflation is also seemed to reduce in most of the countries, improving the purchasing power of customers at large (Monica, 2012). In this similar context, Jochnick (2013) stated that balanced economic policies have assisted countries in improving their respective economic conditi

Personal Statement - Essay Example Out of this brief sessions I acquired practical skill in visualizing, communication practical work among others. In the recent past, I acted as co-producer in the Variety Show hosted by the University of London Hong Kong Society. It presented me with a practical challenge where I utilized my skills to the actual test. Despite this learning and practical experience, I still feel is should continue learning. There is always something new to the world of arts (The Warhol, n.d). Due to my study of diverse art related courses, I have interacted with a large number of people. This has made me develop strong interpersonal skills, leadership skills as we completed tasks as groups. I have been lucky throughout my life to visit Tate Modern Museum where I saw the exhibition of Roy Lichtenstein a Pop Art artist which reignited and strengthened m interest in Pop Art. I also recently attended an exhibition at the Saatchi Gallery (Gallery, n.d) where there was an exhibition of Andy Warhol was exhibited. Andy Warhol is another pop art artist whom I consider my best artist and inspiration. I had a chance to see the works of Peter Blake’s indomitable 1967 album ‘STG Pepper’s Lonely Hearts Club Band.†All this have improved my understanding of the arts not solely as a subject but as a way of life. That is the main reason I find impossible to abandon All these are Pop Art artists that I admire, but I admire Andy Warhol most. Andy was a prolific artist who engaged in a diverse artist works. This diverse artistic works include; hand drawing, paintings, photography, scriptures among others. It is hard to imagine how an aspiring artist can fail to a dmire Andy Warhol (The Warhol, n.d). Pop art is an art that developed in mid 1950s in both U.S and Britain. It makes images from traditional cultures as opposed to the elitist arts. Pop artists engage in arts dealing with everyday life objects and people rather than
