Green to Red Color Change Christmas Chemistry Demo

Green to Red Color Change Christmas Chemistry Demo Color-change demonstrations are classic fare for the chemistry classroom. The most common color change reaction may be the Blue Bottle (blue-clear-blue) chemistry demonstration and the Briggs-Rauscher oscillating clock (clear-amber-blue), but if you use different indicators you can get color-change reactions to suit just about any occasion. For example, you can perform a green-red-green color change reaction for a bit of Christmas chemistry. This color change demonstration uses the indigo carmine indicator. Christmas Color Change Demo Materials One of best parts of this demonstration is that you dont need very many ingredients: water (distilled is best, but you can use tap water if your pH is close to neutral)15 grams glucose7.5 grams sodium hydroxideindigo carmine indicatorbeakers or other clear containers Perform the Indigo Carmine Indicator Demo Prepare a 750 ml aqueous solution with 15 g glucose (solution A) and a 250 ml aqueous solution with 7.5 g sodium hydroxide (solution B).Warm solution A to around body temperature (98-100 °F).Add a pinch of indigo carmine, the disodium salt of indigo-5,5-disulphonic acid, to solution A. A pinch is enough indicator to make solution A visibly blue.Pour solution B into solution A. This will change the color from blue → green. Over time, this color will change from green → red/golden yellow.Pour this solution into an empty beaker, from a height of ~60 cm. Vigorous pouring from a height is essential in order to dissolve oxygen from the air into the solution. This should return the color to green.Once again, the color will return to red/golden yellow. The demonstration may be repeated several times. How Indigo Carmine Works Indigo carmine, also known as  5,5-indigodisulfonic acid sodium salt,  indigotine,  FDC Blue #2), has the  chemical formula is  C16H8N2Na2O8S2. It is used as a food coloring agent and as  a pH indicator. For chemistry, the purple salt is typically prepared as a 0.2% aqueous solution. Under these conditions, the solution is blue at pH 11.4 and yellow at pH 13.0. The molecule may also be used as a redox indicator, since it turns yellow when it is reduced. Other colors may be produced, depending on the specific reaction. Other uses of indigo carmine include dissolved ozone detection, as a dye for foods and medications, to detect amniotic fluid leaks in obstetrics, and as an intravenous dye to map the urinary tract. Health and Safety Information Indigo carmine may be harmful if inhaled. Avoid contact with the eyes or skin, which can cause irritation. Sodium hydroxide is a strong base that can cause irritation and burns. So, wear use care and wear gloves, a lab coat, and goggles setting up the demonstration. The solution may be safely disposed of down the drain, with running water.

No Child Left Behind - Essay Example Next is the improvement of flexibility and local control. It also provides an increased number of options for parents. Lastly it stresses on proven teaching techniques. The phrase, "No Child Left Behind" (NCLB) has become a slogan for the federal scheme to increase "accountability" in American education. But despite the fact that NCLB is a federal plan, it will be up to the individual countries to make the plans and procedures that accomplish NCLB requirements. NCLB does not provide the new mandate with adequate funds. Thus this has an effect on opinions of many schools and parents. Many states have implemented this policy by now, but this has an impact on the parents and schools as they had to face many difficulties while coping up with the policy. This article further describes the effect, changes and pros and cons of the policy in regard to its laws.(Edwards & Perry 2004) This act generally stresses on developing American schools to a standard in which all students are given equal opportunities. As in the act it states "close the achievement gap between high- and low-performing children, especially the achievement gaps between minority and non-minority students, and between disadvantaged children and their more advantaged peers." This clearly reflects that NCLB aims to offer reasonable and equivalent opportunities to the students so that they can attain education of high standards. One of the most important terms of NCLB is the obligation that the states should set values in the field of education and should perform yearly evaluation of schools to check the progress of the school and analyze if the schools have been successful in improving the student's educational achievements. NCLB gives funds for the training of teachers; it provides special support to students who face difficulties with reading and supports immigrants and homeless students. Overa ll NCLB holds the states, districts and the schools to take accountability of the student's achievements. States are entitled to report the progress of students who suffer from problems like reading and writing. They are also directed to report about the students who are from different ethnic groups and who belong to families of low income. On the contrary NCLB has passed laws which act as a barrier for admission in kindergarten. Thus this proves to be a setback for the youth in their future. This youth may suffer from problems like aging, race difference and other physical and mental differences. A child cannot get admission in a kindergarten or a primary school if he has not cleared certain eligibility criterion (Panzica 2008). The laws implemented in the United States of America are prohibiting the children from early entries into kindergarten and primary schools. This can immensely affect the future of the children as it may determine the age of the child when he finishes his high school. There is a certain age limit for any child who needs admission in the kindergarten. If one is not able to comply with the age limits then they possibly will not get an admission into the school. The Act has made the school authorities more accountable for the results of the students and this has therefore made the authorities more conscious when giving admission to a child of less capabilities. The age criterion is so strict that the schools have a certain date setup (usually in September or December) at which the child should be of the

Legal Week 4 Discussion - Assignment Example Peer review can indeed be said to be an effective program within the health sector in achieving quality health care. This is because through peer review, there is a professional back up of the actual health care service that is delivered to service users (World Health Organization, 2011). This is to say that peer review makes it possible for there to be validity of professional medical outcomes, whereby the decisions and actions of medical staff members are subject to third party scrutiny to ensure that all forms of lapses are identified and corrected. In such a situation, the patient or service user becomes the eventual benefactor, getting an assurance that there is always a back up for guaranteed health care. Peer review can also be said to be very effective in promoting peer learning. What this means is that through various peer review methods, professional medical staff are able to learn from their colleagues and peers through the corrections and critique they pass on them. Meanwhile, within the professional medical practice, continuous learning has been noted to be an important process that ensures that service providers are always equipped with the latest service standards to use in rendering quality service (Bond and Bond, 2004). Meanwhile when the service provider is guaranteed to be of high quality, this can be translated into the quality of care (World Health Organization,

English sparkling wine - branding Essay Example | Topics and Well Written Essays - 250 words

English sparkling wine - branding - Essay Example This is a product whose value is augmented by the long periods of standing and fermentation. At the same time, the price is apt enough to stand along the Champagnes using the price advantage. This is creating a brand value for the product. These wines are thus, more affordable and the increased rate of consumption is thus, justified. This growth is also reflected in the returns, which have seen more than 50 percent hike in the last 5 years (Skelton, 2008). The products from English Sparkling wine have won appreciation and awards from many Wine luminaries. These have been on the wine reward and recognition radar from even the ‘90s. The brands received awards such as International Wine and Spirits Awards, Decanter World Wine Awards, Del Mondo World Sparkling Wine Championships and so on (Skelton, 2009). The rewards have thus acknowledged the brand and dealt with the promotion aspect. The health implications of alcoholic drinks such as Champagne, are making the customers switch to safer options. This has also contributed to the promotion of the English Sparkling Wine. This has also influenced the wine choices of the 25-34 year age groups, who form the largest segment of wine patrons (Bainbridge, 2012). The English Sparkling Wine brewers are trying to create a label for themselves (‘Britagne’ is one such suggestion), so that they can be differentiated from the other popular sparkling wine brands. Export promotion is also on their anvil to ensure the viability of the brand (Brown,

Orwells Animal Farm Genre Untangled English Literature Essay

Orwells Animal Farm Genre Untangled English Literature Essay Out of George Orwells repertoire many of his works can be described as somewhat ambiguous in terms of genre. For instance, Down and Out in Paris and London is a recount of his personal experiences flavoured with fictional elements, a semi-autobiography, but it is written in the objective voice of a report, article or documentary with additional sociographic speculations. Many of his essays linger on the boundaries of the short story, as well. Animal Farm is no exception of this Orwellian tendency to fuse different genres. It is often labelled as a dystopian allegorical novella or satire, but has been called a fable in the Aesopian tradition as well. In the present paper I will analyse Orwells work from the viewpoint of all these genres separately keeping in mind of course, that the genres themselves overlap each other in some characteristics and examine how Animal Farm functions as a dystopia, a satire and a fable. While Animal Farm fits some of these characteristics it also lacks in others. It certainly portrays oppression in the form of a totalitarian centralized power, however, in contrast with some well known works strongly associated with the genre including Orwells Nineteen Eighty-Four as well it describes the process of how the utopian dream develops into the dystopian nightmare. Considering displacement it is not really in line with the dystopian trait either. It is for certain that the story takes place somewhere in the English countryside, we are even given the name of Willingdon and The Red Lion, an existing village and pub in East Sussex. Otherwise there is no special importance in the geographical location of the Farm, suggesting that it is not important where it takes place, and consequently, that it could happen anywhere. As for temporal coordinates they are even less specified or notable; the story is not tied to, and thus not untied from any particular date or era. The story could have taken place yesterday just as well as a hundred years ago or in the distant future; it is not dissociated or displaced from either Orwells or todays readers time. (Of course depending on the interpretation of the story, it does allude to the Stalinist regime and the Russian revolution but only externally as its mere allegory not internally to the novellas fictional universe.) However, it could be argued that there is some kind of displacement, not in spatial or temporal terms but in the very nature of the story as a fantastic beast fable or fairy story as Orwell called it. Its characters of talking animals who read and write and manage a farm on their own is surely not a picture of our everyday life. The feature Animal Farm most clearly adopts from the dystopian genre is the intention of warning. It warns of the danger of communist dictatorship and raises the attention as well of the existing conditions present at the time in the Soviet Union; or in a more general interpr etation the corrupting effect of power when exercised by anybody  [1]  . However, the element of warning or at least criticism of human vices or follies with the intention of improvement  [2]  is also representative of the satire. Although it is usually meant to be funny, its purpose is not just humor for its own sake but an attack on something the satirist strongly disapproves of and to persuade the reader (or viewer depending on the medium) to strive for a solution to the problem presented, using the weapon of wit, irony, and caricature.  [3]   In Animal Farm the satirical irony emerges from Orwells style of narration and his use of the animal allegory. The narrative style he employs is characterized by simple language and light, objective even impersonal voice with the limited point of view of the enslaved animals. The plain language on the one hand is to reflect the naÃÆ' ¯ve perception of the animals  [4]  , on the other this terse phrasing is set in ironic juxtaposition[to] the crassly elitist, manipulative, unintelligible, and circumlocutory discourse of the pigs, through which the fictitious passes off as factitious.  [5]  Samir Elbarbary in his essay Language as Theme in Animal Farm even argues that the conscious derangement of language, and linguistic superiority which sustain the assumption of power, is one of the novellas fundamental thematic concerns. Language and how language can influence or even determine the way people think is often a recurring theme in Orwells works, for example the idea of Newsp eak in Nineteen Eighty-Four, and he even addresses the problem directly in essays, such as Politics And The English Language, in which he attests for simple uncomplicated language in scholarly and especially in political contexts. According to Elbarbary, in Animal Farm the revolution is, in a sense a language-focused enterprise, a product of specifically aggressive linguistic energy, and language  [6]  , which can efficiently control reality, is the source of the tragic outcome rather than its mere reflection. Those animals who have an underdeveloped language, are compleatly overpowered by the linguistic skill of the pigs; their ensnarement is less a matter substance than of generic linguistic impotence and deficient semantic memory.  [7]   Even thought the point of view of the narrator is limited (or at least it is more distant from the feelings or thoughts of the pigs than that of the other animals), the narration still implies more to the reader than the animals themselves are aware of. We understand the difference between the truth of a situation and what the characters know about it, while the characters remain ignorant of the discrepancy, which creates dramatic irony. For example when Squealer explains that the van in which Boxer was taken to the hospital formerly belonged to a horse slaughterer and that the veterinarian who now uses it did not have the time to paint over the horse slaughterers sign on its side, the narrator says: The animals were enormously relieved to hear this.  [8]  The reader however, can assume the truth right when the van appeared to carry the horse away. Another level of satire is in the characterization. Orwell attributes easily recognisable human traits to animals, which remain absolute, that is they are character types rather than fully developed characters, without the ability to grow or change, the animals shall stay both animal and human. It removes the possibility of very complex characterization.  [9]  In the light of the parallel that can be drawn between the story and the Russian revolution, some characters are clear caricatures of exact historical figures (like Napoleon-Stalin, Snowball-Lenin) others of specific social groups or classes or even tools used to uphold dictatorship (e.g. Boxer-working class, Squealer-propaganda), creating a grotesque mirror image not just of the events but the figures involved in it, enhancing the validity of the satirical parallel. The third genre considered here is the already mentioned beast fable. It is usually a brief tale that conveys a moral lesson, usually by giving human speech and manners to animals. It is a very old form of story related to folklore and proverbs, the fables in Europe descends from tales attributed to Aesop, a Greek slave in the 6th century BCE. The French fabulist La Fontaine revived the form in the 17th century with his witty verse adaptations of Greek fables.  [10]  The form can be associated with the satire as well as the beast fable is also used as a culturally universal satirical technique. It is basically the dramatic realization of a metaphor and satirists have always found this translation of metaphor to dramatic fact an extremely effective way of portraying the true nature of vice and folly. As far as characters, style and language (its simplicity thus serving double causes) Animal Farm fits the criteria of the genre. According to Christopher Hollis the writer of the beast fable must throughout be successful in preserving a delicate and whimsical balance due to the overall absurdity of animals behaving and talking like humans and discussing complicated intellectual problems. He argues that Orwell is able to maintain this balance by avoiding any unnecessary explanation of the fantastic elements of the story in an otherwise realistic setting.  [11]   However if we take into account its length it is considerably longer than the traditional fable. In addition, some point out that its moral lesson is questionable or nonexistent as it is impossible to attach a moral to any familiar sense to Animal Farm, where wickedness ends in triumph and virtue is utterly crushed.  [12]  I do agree that there is no lesson to be learned in the fashion of for example The Tortoise and the Hare, however I believe that there are moral undertones embedded in the overall message of the novella, like power corrupts; it is a moral lesson without answers, or a moral tragedy of humankind. In conclusion, Orwells Animal Farm seems to function best as a satire but he consciously incorporated techniques and elements of other literary forms, most elaborately of the beast fable, to use it as his satirical vehicle. As for the dystopia genre it seems to be a little farfetched to attach the term to Orwells novella, it is more like a loud hee-haw at all who yearn for Utopia.  [13]
