Baggie Chemistry Experiments

Overview An ordinary ziploc bag can unlock a world of interest in chemistry and in the reactions within and around us. In this project, safe materials are mixed to change colors and produce bubbles, heat, gas, and odor. Explore endothermic and exothermic chemical reactions and help students develop skills in observation, experimentation, and inference. These activities are targeted for students in grade 3, 4, and 5, although they may also be used for higher grade levels. Objectives The purpose is to generate student interest in chemistry. Students will observe, experiment, and learn to draw inferences. Materials These quantities are suitable for a group of 30 students to perform each activity 2-3 times: 5-6 plastic ziploc-style bags per lab group5-6 clear plastic vials or test tubes (may be used instead of baggies)1 gallon bromothymol blue indicator 10-ml graduated cylinders, one per lab groupteaspoons, 1-2 per lab group3 pounds calcium chloride (CaCl2, from chemical supply house or from store selling this type of road salt or laundry aid)1-1/2 pounds sodium bicarbonate (NaHCO3, baking soda) Activities Explain to the students that they will be performing chemical reactions, making observations about the results of these reactions, and then designing their own experiments to explain their observations and test hypotheses that they develop. It may be helpful to review the steps of the scientific method. First, direct the students to spend 5-10 minutes exploring the lab materials using all of their senses except taste. Have them write down their observations regarding the way the chemicals look and smell and feel, etc.Have the students explore what happens when the chemicals are mixed in baggies or test tubes. Demonstrate how to level a teaspoon and measure using a graduated cylinder so that students can record how much of a substance is used. For example, a student could mix a teaspoon of sodium bicarbonate with 10 ml of bromothymol blue solution. What happens? How does this compare with the results of mixing a teaspoon of calcium chloride with 10 ml of indicator? What if a teaspoon of each solid and the indicator are mixed? Students should record what they mixed, including quantities, the time involved to see a reaction (warn them that everything will happen very fast!), the color, temperature, odor, or bubbles involved... anything they can record. There should be observations such as:Gets hotGets coldTurns yellowTurns greenTurns blueProduces gasShow students how these observations can be written down to describe rudimentary chemical reactions. For example, calcium chloride bromothymol blue indicator -- heat. Have the students write out reactions for their mixtures.Next, students can design experiments to test hypotheses they develop. What do they expect to happen when quantities are changed? What would happen if two components are mixed before a third is added? Ask them to use their imagination.Discuss what happened and go over the meanings of the results.

The Legal Definition Of Terrorism - 960 Words

Most citizens would define terrorism as using force to influence or change a political decision, â€Å"the legal definition of terrorism has very high importance† (Hodgson). This is because it determines which actions count as acts of terrorism, and hence who is regarded as a terrorist, but also because the definition of terrorism opens up a range of controversy of police and prosecutorial powers. Terrorism has always been an iffy subject to talk about and define. In its original text, terrorism was closely associated with the ideals of virtue and democracy. Terrorism now is the harming and/or killing of civilians and the damaging of property while causing economic harm for the reasons that the terrorist are trying to portray by violence. Understanding all the pieces to the puzzle the government and Americans go through on a daily basis, most would agree that terrorism is the worst thing to happen in the world, aren’t physically able to handle it, but are asked to deal with it while the government and military try to find a positive solution. Terrorism is something people in the world need to understand the true meaning of, and it means the use of violence and intimidation in the pursuit of political point. When looking at the outline of terrorism from the outside point of view there are three different ways to see it: the terrorist’s, the victim’s, and the general public’s. â€Å"The phrase â€Å"one man’s terrorist is another man’s freedom fighter† is a view terrorists themselves wouldShow MoreRelatedGovernmental Agencies and Terrorism640 Words   |  3 PagesAfter the 9/11 attacks the word terrorism became etched in the worlds vocabulary.

Becoming a Social Worker Free Essays

Becoming A Social Worker Sindy Griffin Rasmussen College Author Note This research is being submitted on June 10, 2011, For Ian Provo HS100/HUS1001 sec01 Introduction to Human Services at Rasmussen College by Sindy Griffin Growing up in the 1970’s where there were limited resources, and having an abusive father was very difficult for my mother and us four children. Having such difficult times as a child though no fault of my mothers and then being married to an abusive husband for 18 years myself, has given me the strength and desire to become a Human Service Worker. Becoming a Caseworker will be fulfilling a lifelong dream to help those in need no matter the crisis they may be seeking to cure. We will write a custom essay sample on Becoming a Social Worker or any similar topic only for you Order Now In realization becoming a Caseworker has many responsibilities. Some of the main responsibilities include:† Verifying information through interviews, applications, and applying regulations and memoranda to provide income to individuals and families. † (US Department of Labor, 2010-11). Optimizing client functioning by providing quality services in an efficient and effective manner to people with complex needs. Being a caseworker requires a strong foundation of training, values, knowledge, theory and skills. Clients who have been identified as in need as the result of an outreach or referral service can be assisted by a caseworker, which must then conduct face-to-face assessments of the client’s strengths and weaknesses, as to conduct research for financial and or institutional recourses that may be available for the client’s individual needs. Many resources may be used in this process to insure the client receives some if not all the requested needs. Some of the responsibilities are as follows: In a case where a client came to me and requested assistance to escape from an abusive husband, I would assist her first by analyzing her situation to properly resolve her immediate needs, such as shelter, food, clothing and etc. We would then progress to other needs such as legal, emotional and psychological support. Researching outside sources would become the most of priority to give the client the help she is requesting. We will also have many clients come forth with substance abuse problems as well. Again we must analyze his or her situation to determine what resources are available for the client. Whether it be simple counseling or a rehab center. We must then try talking to the client about what they think the best treatment plan would be for themselves to overcome their addiction. These situations have to be handled gently as not to scare the client away. Developing a relationship to the client is very important in this situation. Once this has been accomplished the client will be more acceptable to change and be prepared to move on to outside agencies or support groups to assist with their addiction. A Caseworker must also meet the required education standards which are as follows: â€Å"The social work case manager shall have a baccalaureate or graduation degree from a social work program accredited by the council on social work education. † (Workers, International Federation of Social) A social worker must also use professional skills for all clients they attempt to assist, while keeping the information confidential. They must also be knowledgeable as to the resources that are available to the client, as well as knowing the cost of such resources. The caseworker should be sure they can handle the caseload they attempt to assist as to not leave anyone out. Being very committed to our job is one of the main keys to being a successful caseworker. A Caseworker will also experience many challenges along the way. These challenges will have to be handled with a smile and lots of patients as to not let the client see that you may be distressed. Although there are many challenges we will face along the way, one of the main ones is the case overload. Many caseworkers today have an over abundance of cases at one time. This problem causes the paperwork process to be slow and seem as though we are not doing our job, causing the client to become frustrated and feel as if they are not getting your full attention. Being able to communicate with the client should be of utmost importance as well as assuring them that you will in fact complete their case as soon as possible. There are also many stress outlets that come along with our profession as well. We may face this on a daily basis as well. One of the most common in our field is rude clients and emotional attachment. The loyalty of a caseworker is often in the middle of a conflicting interest. † (Workers, International Federation of Social) Meaning that as we do our jobs as caseworkers, we may also come across situations that we have encountered ourselves as a non-caseworker and actually experience some sort of favoritism to the case at hand, in turn we this could cause a conflict with the interest of your remaining clients. Caseworkers must re member the urgency of all of their cases not just the ones that mean the most to them. Clients that become rude may only be acting in this manner because they feel as if they are being ignored and that they will not receive the proper assistance as quickly as they anticipated. This type of action may cause undue stress on the caseworker to complete their case. We must be able to some how assure the client we are working on their case as quickly as possible and they will be contacted as soon as it is complete. Handling stress that comes with being a caseworker can be quite challenging in itself. One of the first things I may try and do is try and remind myself of the reasons I chose to become a caseworker. Though our jobs may be stressful in many ways we have to remember the desire we had or have to help those in need. We may also learn that just simple things like taking a walk or stopping and making a phone call to a friend or colleague can reduce the amount of negative energy we may be experiencing. Co-workers can be great stress relievers as they too experience the stress that is closely related to what you may be feeling at that time, after all we are here to help one another not only help the client in need, but those who work closest to us as well. The reason I have chosen to become a Social Worker is that I have a strong desire to help those in need. No matter what their issue may be. I believe there is help out there for everyone. I want to be part of the reason some of the ones that are struggling in this world today will be able to find hope and succeed in their lives. Although my job will come with many challenges, requirements, and responsibilities, it will not let me forget the reward I will feel in my heart that someone somewhere is beginning a new life because we stopped long enough to let them no that they could. Just as â€Å"Jane Addams, who is considered the mother of all social workers said: Civilization is a method of living, an attitude of equal respect for all men. She is known for being one of the most famous social workers of all times, using her training and education to do only good. † (Article Pros , n/d) . I too hope I can be one of the greatest Social Workers of all times. Conclusion Although there are many responsibilities and requirements in the caseworker field of employment, and the job consists of lots of commitment and research to assist clients with their psychological and physical needs. Case Workers must understand the complexity of all cases they have, as well as knowing who and where they need to refer the client to for their specific needs. Keeping in consideration the Caseworker poses so many challenges, stress and stress outlets, We as Caseworkers must remember that we are here to help those in need. They are like harmless children waiting to be saved from the world. Overcoming the many challenges and stressful situations is what we have been waiting to do our entire lives. We just have to remember the compassion and desire to be a Caseworker is instilled in us and we should never forget its value to the client in need or ourselves. By doing all these things we can make a difference in the world one case at a time. Becoming a Caseworker is my life long dream. Being able to help those in need will give me the fulfillment in my life I have been missing for so many years. Just waking in the morning and knowing that I could possibly save someone’s life or even just give them a sense of belonging makes all the esponsibilities, requirements, challenges, stress and commitment worth the effort.

Acer Revised free essay sample

Acer Inc. is a leading multinational electronics manufacturer. It is based in Taiwan Acerland. One of the largest franchised computer retail chains in Taiwan is owned by the company. After HP and Dell, comes Acer in terms of being the largest computer makers in the world. Its product line-up includes desktop and mobile PCs these are also referred to as laptops. The company also makes Personal digital assistants (PDAs), servers, displays, peripherals and e- business solutions for businesses, governments, education and home users. The Acer history is really an interesting one. Initially, the original owner of the company was called Stan Shih who together with his wife Carolyn Yeh and a group of five others had founded the company in 1976. At that time it was called Multitech. After Tom Acer bought it, he renamed it to the Acer group company. (Prahalal, 1989) The Acer Company began with a capital of $ 25,000 and eleven employees. We will write a custom essay sample on Acer Revised or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page At its initial stages, it only dealt in distribution of electronic parts and being a consultant in the use of microprocessor technologies. It has its headquarters in Hsichih city, Taiwan. Tom Acer managed the company well and with time it started having dealings in other areas. Acer started focusing on branding business in 2002. The company grew in size and expanded tremendously after reaching a decision of supporting the sales of its product lines through specific marketing activities, that utilize distribution channels effectively. (Luchs, 1996) The Acer Computer Company The Acer Company continued growing in size until it became really big. The problem that it faced at this juncture is that its labor force contracted. The employees that had been hired initially could not be able to deal with the increase in the workload that the Company experienced that time. Therefore other employees had to be recruited to be able to handle the workload efficiently. In 2002, the Acer group employed 39,000 people, supporting dealers and distributors in more than 100 countries. The performance of the Company made the U.S. get revenues of up to $ 12.9 billion that year. By the year 2005, Acer had employed 7,800 people throughout the world at the same time maintaining a global service network and sales. The U.S. continued getting an increase in its annual reviews from the Acer group. In Europe Acer made an association with Ferrari Formula 1 Team and the former F1 team, Post Grand Prix in 2001. These Companies offer a popular line of LCD monitors and Premium laptops with Ferrari branding. Recently, Acer has announced that it will sponsor the Formula one team until 2008.And in doing so; it has broadened and strengthened its relationship with Ferrari. New Ferrari line of products has recently been introduced to North America, by the Acer Company. (Prahalal, 1989) cer has faced the challenge of competing in the first changing information technology industry. This has necessitated it to reformulate its corporate strategies and change its organizational structures three times since the early 1990s. The last two changes have occurred within a two-year period to overcome the emerging internal problems and respond to imminent external changes. I n 1990, it suffered a huge loss in the overseas investments. The Company was questioned of its continued investment plans in the overseas where it was doing badly at the time. It was even criticized as moving very first. The shareholders and the employees did not offer much support to the company. The shareholders were very angry that the money they had so hard worked for was being lost to overseas operations. A solution had to be reached at, very first if the shareholders’ money was to be recovered. The Company came up with a new strategy of â€Å"global brand, local touch†. This solved most of the problems that Acer was encountering at the time such as finance brand, name image, and management efficiency. In doing so, it rewrote the rules of the old tradition where multinational companies only went global instead of concentrating with the local market too. This made Acer become the number one Computer brand in Latin America, South East Asia and the Middle East. Acer Company faced the problem of establishing an effective Multinational management. It was too much for the Company to manage its businesses in other countries locally. Therefore, the company was able to give up local efforts and in its place; it employed capable local executives for overseas operations. It was able to establish an effective management tool instead of quitting. This led to an office being established in the U.S. by the Acer group. Acer has also at some point made losses by making acquisitions in the wrong way. The correct way was by following the thinking pattern, better known as the acquisition of counterpoint in 1987 and Altos in 1990. This was bad for the Company for it lost both talent and asset. The company had to pay goodwill and incur extra expenses. Fortunately for the company, both capital and workforce stayed with it to fight for the future. The management teams stayed to work for Acer, while the shareholders of Counterpoint and Altos, sold their stocks in exchange for cash. In the long run, the company was able to recover once more. (Jack, 1970) When Acer Company was still small, its internationalization was relatively successful. It carried out its businesses without issues of inventory and credit lines. However, it had to extend credit lines and increase inventory when it expanded. This made it increase its operating cost and it also incurred bad debts and inventory caused by wrong forecasting. Acer slowly solved the problem by establishing its credit management system in countries where it has its operations. The Acer group has numerous advantages and strengths that make it a leading computer manufacturing Company in Asia. First, it continues to tap the urge to become the boss by giving decision-making powers to local managers in Acer plants and offices around the world and letting them run operations like managers. This urge has kept the Acer Company strong in its operations as it is assured of effective management. Secondly, Acer is unique in the fact that it has the willingness to give up control and majority ownership of its local operations. This motivates the growth of the Company, maximizing its profits ensuring that the Company runs successfully. Thirdly, the Acer Company has fresh technology for everyone. The Company ensures that the fresh technology it has is enjoyed by everyone, and everywhere. The Company’s Vision has strongly brought this out. This attracts many customers which translate to larger profits for the Company. (Prahalal, 1989) The Company has also its weaknesses. The Acer Company cannot compete on its own in big markets. North America and European markets are dominated by â€Å"big guns† like Intel and IBM. These Companies are far much bigger than Acer. For Acer to match this competition, partnership and acquisition of other IT companies is a good alternative for Acer. The competitive advantage of Acer is gradually going away due too the introduction of internet .This has made the division of labor and capital disappear. The Company has to adapt to the changing world and develop new set of policies. (James, 1998)
