Galvanic or Voltaic Cell Definition

Galvanic or Voltaic Cell Definition A galvanic cell is a cell where chemical reactions between dissimilar conductors connected through an electrolyte and a salt bridge produce electric energy. A galvanic cell can also be powered by spontaneous oxidation-reduction reactions. Essentially, a galvanic cell channels the electrical energy produced by the electron transfer in a redox reaction. The electrical energy or current may be sent to a circuit, such as in a television or light bulb. The electrode of the oxidation half-cell is the anode (-), while the electrode of the reduction half-cell is the cathode (). The mnemonic The Red Cat Ate an Ox may be used to help remember reduction occurs at the cathode and oxidation occurs at the anode. A galvanic cell is also called a  Daniel cell or a voltaic cell. How to Set Up a Galvanic Cell There are two main setups for a galvanic cell. In both cases, the oxidation and reduction half-reactions are separated and connected via a wire, which forces electrons to flow through the wire. In one setup, the half-reactions are connected using a porous disk. In the other setup, the half-reactions are connected via a salt bridge. The purpose of the porous disk or salt bridge is to allow ions to flow between the half-reactions without much mixing of the solutions. This maintains charge neutrality of the solutions. The transfer of electrons from the oxidation half-cell to the reduction half-cell leads to a buildup of negative charge in the reduction half-cell and of positive charge in the oxidation half-cell. If there were no way for ions to flow between the solution, this charge build-up would oppose and half the electron flow between the anode and cathode.

Choose one promt to write about - Essay Example The shrink convinces the mother that she is in danger from her husband who wants to kill her and therefore, must leave him before she gets killed. The mother and son’s living arrangements were decided by the psychologist, the mother was to stay at a motel while her son stays with her shrink’s family. The doctor manipulated the main characters in the story for them to be live lasciviously and become dependent on drugs, limiting their developments in life. The mother had an illicit affair with a female friend while the son had sexual relationship with a male patient of the doctor. After so many struggles, the mother finally had her works published and was starting to stand strong however, she found out that she was deceived by her own doctor with the money her husband sent to support their son. Consequently, she stayed away from her shrink while his son went away from her to start his own new life. The aforementioned film exemplifies the making and breaking of a mother an d son relationship which this paper will further discuss, expounding on how relationships are developed and destroyed. Relationships are very important because as social beings, people cannot avoid building relationships. More importantly, family relationships are valuable to every human being because it is in the family that basic principles about relationships are established. In the film Running with Scissors, the relationship of the mother and son was initially good. The mother was adored by her son because she has shown how much she cared for the child and the mother in turn loved and cared for her son. However, the mother and son did not quite have a good relationship with the workaholic husband and father although this seemed to draw the two together as confidants and allies. The boy grew to empathize with his mother as the abused partner so that he did little things such as preparing tea to serve her mother and show his fidelity and care. The mother influenced her son even f urther by sharing with him her every dream and involving him with her plans (Murphy). The relationship of the mother and son is obviously good in the beginning because the mother worked hard to maintain good communication between them despite their circumstance with the father. The mother shared her career plans with her son which might have been good for his learning. The son in turn looked up to her mother. The two became encouragements to each other even during tough times. As a result, they formed a strong bond. When the mother and father fought in front of the boy and the father was knocked off and fainted as he attacked his wife, the father was never seen as a victim in the eyes of the son. Instead, of getting shocked with how the mother spoke against her husband, the son instead feared for his mother’s life than his father (Murphy). This only shows how he supported and protected his mother as a result of the relationship that they formed. On the contrary, the relations hip of the mother and child could also be considered not very normal, at least on the part of the child. The mother sharing her problems with her son at a very tender age somehow made the child feel the strain that she was going through. Therefore, the son did not have a normal childhood. Instead, he seemed to have grown extremely emotionally attached to the woman so that he imitated her in most of her actions, including how she dreamily delivered her speeches. As the

National V State Curriculum Essay Example for Free

National V State Curriculum Essay The issue of state vs. National curriculum has been raging for many years now with the Australian national government trying to force a national curriculum on all states and territories. However for this work all states and territories must agree on the curriculum and with so many different ways of teaching and how students have been taught in the past it was always going to be a difficult assignment. New South Wales, the leaders is assessments and with what they believe is a superior curriculum, have been the main fighters of the curriculum. New South Wales believe a national curriculum could work based around parts of their own curriculum as well as improvements in teaching development, management and mentoring. The implementation of an Australian national curriculum will mean huge changes to not only the New South Wales educational system but the educational systems of all states and territories. This will also mean a change in the New South Wales syllabus in order to make it fit with the national curriculum. As well as this it will not only will this impact on the education systems within Australia but will also mean a new requirement for teachers to teach at the level required to allow a national curriculum to work. New South Wales believe that the federal government is trying to lower the standard of education across the state in order to fit with the national curriculum. The New South Wales has long fought for the curriculum to be upgraded to fit with their syllabus so that when the nation does get brought to a certain level that level it is brought to is a high level of education giving everyone an opportunity at a better future as a whole. Not all the education departments agree or want the changes that will be brought in by a national curriculum. The New South Wales educational department are the main fighters of the implementation of the national curriculum. New South Wales believe the state curriculum they have in place alongside the HSC is more than adequate enough to suffice as a national curriculum for all states and territories. The development of the new national curriculum will mean changes to the New South Wales syllabus. This includes the introduction of mechanics back into the syllabus as well as the introduction of plants into the reproductive part of the syllabus. The latest version of the national curriculum from the Australian curriculum website shows step by step how the national curriculum looks to improve the standard of scientific knowledge taught across the country. It goes in depth to show how from year 1 right through to year 10 they will be building on skills learnt from previous years of science education. The latest version of the curriculum then goes on to tell of the more in depth science will be taught from years 7-10. This curriculum is able to show how the nation will be brought to the same standard of science knowledge through primary and secondary education. As well as this the Department of Education in the draft national curriculum for science (ACARA 2009) argue that although there will be new areas of study the curriculum will be more flexible for teachers allowing them to better teach the science curriculum. The draft curriculum also outlines 8 forms of considerations that will hopefully close the gap between indigenous, foreign and disadvantaged students. These considerations include Equity and Opportunity, Connections to other learning areas, Clarity of the curriculum, Breadth and depth of study, The role of digital technologies, The nature of the leaner (K-12), General capabilities and Cross-curriculum perspectives. The Department of Education are hoping that this will bring all students, schools and teachers up to a certain standard that this national curriculum will hopefully bring in. Bringing the students, schools and teachers up to a national standard will also hopefully make it easier for teachers to educate the students on topics and allow a bit more flexibility for the teachers in the classroom. The Australian national curriculum will also impact on the science pedagogy. Aubusson (Australian Journal of Education, 2011) believes that the curriculum will force one of two pedagogical situations. Aubusson believes the pedagogy will change to a standardising pedagogy or a pedagogy that will allow teachers to interpret the curriculum and teach it to their students in a way they will understand best. The standardising pedagogy could potentially lead to teachers being unable to form a connection with their students which could in turn cause students to become uninterested in the topics. This could potentially lead to a large amount of students failing the course. However a pedagogy which allows teachers to interpret the curriculum so they know which way will be the best to teach their students will allow connections to be formed, students to remain interested and engaged in their education and will lead to an increase in examination marks. This brings me to the teacher development issue with the national curriculum. Many teachers and education professionals in New South Wales oppose the change is due to the drastic development teachers will need to go through to allow the national changes to work. As sourced from the article ‘Mentors Reporting on Their Own Mentoring Practices’ (P. Hudson 2010) Hudson refers to his own personal experience of the failure of the last national curriculum. Hudson was a New South Wales school principal at the time tells of how he believes the failure can be partly blamed on the lack of development training offered to the teachers to allow them to teach the nation curriculum. New South Wales teachers and other teaching professionals believe that all Australian teachers need to go through development so that they are able to recognise the ways in which their students learn the best, this will enhance the students learning environment and allow them to work better as individuals and as a group. Teachers across Australia need to be able to understand and recognise the VARK learning system. The VARK learning system basically just asks the question of how students learn best. Whether they are, V – visual learners, A – auditory learners, R reading and writing learners, or K – kinaesthetic learners. As well as being able to recognise this VARK concept and implement it in the classroom teachers will also need to be able to recognise when things aren’t going to plan so they can improve their own teaching skills and the learning environment of the student. This will require constant reflection on the teachers on behalf, they must regularly reflect on how the lessons have gone. Doing this will not only help the teacher improve of their work and how they teach the curriculum but it will also help their students better understand the knowledge put before them. This means that teacher development is a must for the national curriculum to succeed for a long period of time. New South Wales are leading the way with teacher development, understanding and practices for the national curriculum rollout. The Minister for Education Mr Piccoli has stated in the past the NSW government is allowing their schools time to adjust to the changes the new curriculum will bring is. The government for NSW is delaying the implementation of the curriculum to give NSW schools and teachers time to prepare for these changes as well as time to implement the preparations. On August 9, 2011 Mr Piccoli stated that the national curriculum will not be rolled out across NSW schools until 2014 with the preparation and planning for the national curriculum to commence around 2013. Management is a key actor in the success of the national curriculum. For the curriculum to work steps must be put in place to manage the introduction of the curriculum as well as the up keep of the curriculum changes. Early teacher or Preservice teachers will be benefitted by the fact that most of them will be starting their full time jobs around the same time the curriculum is rolled out allowing them to focus on the new curriculum and what needs to be done. However the older teachers might struggle at times to recognise where change is needed from the old curriculum to new, this is where the management side of things comes into play. As cited from the mentors report (Hudson, 2010) teachers must help and mentor each other. There will be this area of overlap where the preservice teachers will be able to help the older teachers understand the changes from the old to new curriculum whilst the older teachers are able to help the preservice teachers in understanding the way in which the classroom works and how to better understand how their students work. This management and mentoring role comes from within the staffroom of the school and head teachers and principals must work together to achieve this mentoring and management role. Another key way for this mentoring idea to work is for teachers to give feedback on each other to help them improve. Hudson believes a method of understanding personal attributes, system requirements, pedagogical knowledge and modelling are all helpful in giving and/or receiving feedback. If colleagues are able to give and receive positive and critical feedback well the standard of teaching will only improve. With the standard of teaching improving the curriculum will get taught better to students which will in turn mean an increase in examination marks causing the national curriculum to work and to stick. With a new curriculum coming into place new resources will be needed for teachers to educate their students whilst still keeping them engaged in the lesson. Not only will some new resources be needed but some of the older teacher’s resources could be irrelevant. This is where that teacher development will come into play again; teachers will need to recognise where new resources are needed, where older resources aren’t needed and where some are still relevant. Again this will require all the teachers to come together and help one and other with this dilemma and help share resources in order to give each student the same learning experience. However new sources will be readily available to teachers with many websites out there having new up to date information to show the children. There are also many sites out there with activities the teacher can do online with the class to keep them engage, there are also videos out there that contain the information required for the national curriculum to show the students as well. So although new resources will be needed there are still many places teachers can find resources to keep their students engaged. As a first year university student studying teaching in the New South Wales education system I believe a national curriculum is vital for the future education of our next generation. However I do believe New South Wales were right to fight for the curriculum to be brought up to their standard because if we are going to have every student at the same level of education it should be at the highest level possible to give every student the best opportunity possible to have a successful life after school. The national curriculum will work throughout the country as long as teacher development is put in place as well. Teachers need time to develop and adjust their own teaching techniques so they can best teach this new curriculum to their students. Teachers in all schools will need to work together for this national curriculum to succeed in our schools to give the next generation of young Australians the best chance at success.

How American are American Samoans? :: History Samoans Samoan Essays

How American are American Samoans? Since the 19th century, historians have defined three major waves of American immigration particularly from countries in Europe, Asia, and Latin America. In the case of American Samoans, the native population of the United States Territory of American Samoa, emigration from these islands began in the 1950’s. However, unlike other ethnic groups, like the Mexicans and Chinese, who were also arriving in the U.S. around the same period, American Samoa was already part of the union for nearly 50 years, yet, the natives’ desire to migrate to Hawai’i and the mainland seemed to surface slowly. Although explanations for this delay in the movement of American Samoans are complex, historians have argued that besides the growth in curiosity and adventure of the outside world, American Samoans were forced to leave their homes because they simply had no other alternative to choose from. With the involvement of the United States, especially that of the U.S. Navy, the Samoan s grew dependent on the resources, protection, and economic prosperity that the American foreigners introduced and continued to provide from the time of the cession of the islands in 1900. When the U.S. naval base, which was established in Pago Pago, the current capital city, was relocated to Hawai’i in the early 1950’s, work in American Samoa was limited and the natives were not willing nor prepared to return to farm and agricultural work. As migration to the "mainland" became more appealing to the islanders, their American Samoan status as U.S. Nationals was, (and continues to be to this day), confusing and somewhat contradictory to the policies of American citizenship. As American Samoans have discovered, U.S. Nationals are granted "privileges" such as entrance to the United States. However, American citizenship is not part of the package, which greatly limits the political voice of these natives. To understand the disrupted social, political, and economic state in which the American government left American Samoa with the closing of its naval base, a brief historical overview of the Samoan archipelago is necessary, which will discuss the appeal of the islands and its location to foreign powers, U.S. diplomacy, and the push and pull for migration to the U.S. mainland. Samoan people are known for their rich culture and heritage, but the history of their islands is virtually unknown. From 1870 to 1914, countries like Germany, France, the U.

New Respiratory Poses Potential Threat to Humans

There are a lot of new bacteria and viruses being discovered almost every day. Some of them are new strains of previous species while some are entirely new species that have yet to be studied and usually cause no harm to humans. However, when the Adenovirus, the causative agent of the common cold, which is not a lethal illness to most people, mutates into a new form and mysteriously kills a lot of people, this is a cause for alarm. In this connection, according to an article written by Associated Press and was published in Quad City Times, a mutated form of the Adenovirus has killed 10 people across the United States in last 18 months. In addition, the new form, which is called Ad14, has caused 140 illnesses in states such as Washington, Texas, Oregon, and New York. The virus was first reported last year in New York City, where it killed a 12-day old girl. Based on the article, the Centers for Disease Control and Prevention (CDC) was puzzled by the new strain of the Adenovirus, which has only more than 50 variants. However, they emphasized that there was no need to be alarmed as the mutated virus does not pose a serious threat to humans. Moreover, the CDC is also working on a vaccine for the virus which they hope to release in 2009. What fascinated me most about the article is the fact that the Adenovirus, which usually causes mild forms of sicknesses, has mutated into a new and possibly, deadly form. Being a student taking up microbiology, I believe that this discovery of a mutated variant of a virus means that it is possible for other viruses, and even bacteria to mutate into a more lethal and more dangerous form. It is possible that the virus was exposed to certain factors which altered its nutritional requirements and as a result, made it evolve like in the case of certain bacteria such as E. coli.

Media And Its Effect On Society - 1087 Words

Media is a tool that has been seen to control much of the world. More specifically it has the power to make people second guess themselves. Many images on today’s media are affecting the way people think. There seems to be an unrealistic body image the media presents, which affects the viewing public greatly. Time and time again, the media falters to make an impossible image for men to achieve, but does make unrealistic images for women to achieve constantly. Recently this has changed as many magazines, such as â€Å"Men’s Health,† make men aware of a body image that is not achievable or in other words average. There seems to be a â€Å"†¦realization that this magazine, and a handful of others like it, are leveling the playing field†¦,† (Brown,†¦show more content†¦The fact that statistics like this are being said is relieving women and the stress that is placed on them to keep up an image of beauty that is extremely hard to maintai n. In addition to men finally being scrutinized by the media, the media also takes an unfair attack on the weight of people. In our consumption-addled culture, the mass media encourages us to absorb as many goods as possible far beyond the saturation point. The media has gone as far as to make people believe that more of anything; for example food, clothing, etc., can create the image of anyone to become sexier or more successful. There is one â€Å"†¦notable exception: if a women is perceived as having consumed too much food, she finds that she has committed a social crime† (Goodman, W., 1995, p. 54). This serves to be a flaw that the media has faltered in catching, but does not really care because if this â€Å"social crime† is committed it allows room for more T.V. ads about weight loss pills and for magazines to print in their next issue about a new found diet or pictures of â€Å"beautiful† skinny women. Women are punished if they follow the rule that more is better, but men are left out of the loop. It is clearly seen in movies, where actors such as the late John Candy, Chris Farley, and John Belushi, who were all obese men, found fame and glory due to their weight. For example, in a scene from the movie
