What Is Calibration in Chemistry?

What Is Calibration in Chemistry?There are several questions regarding what is calibration in chemistry. It is the examination of the material samples for results. The material samples are that used for calibration testing, which has a slightly different content from that in which the sample was analyzed. The difference is that it must be known to be identical and that the differences do not need to be added up.One may come across many problems if the difference is left out and one cannot get the same effect for an effective result. However, with the aid of calibration in chemistry the quantity is tested and found to be the same or similar to the experimental results.The results are correct but in the sense that the substance is similar to that in which the testing is done, but the amount is different. This happens when the original composition of the substance is quite different from that in which the material was tested. This is called impurity or contamination.Laboratory of any re search or company will use this substance for the testing and checking the chemical composition of substances and also their properties. When the amount of impurities is small and the contents are standardized the result of the test may be accepted as proper. However, if the impurities are large then the result of the test is not valid.The situation is reversed with the impurities which are large. They are going to affect the result. This is known as the impurity. It is only in laboratories where there is constant checking of the substances that such impurities are recognized and there is a way to correct the difference.In order to check one's test results, one will have to take some time to understand the process. By learning about the chemistry involved and practicing, one can have a better idea about the facts. A few simple things will help one in getting a good idea. The problem with calibration in chemistry is that people seem to underestimate the importance of knowing the impu rities.However, it is useful to know what they are before they are used. Knowing them and being able to correct them can make the results of the test very accurate. It is even more important to use the right quantities of substances in the test so that the results are accepted without error.

Should Schools Teach Character

Should Schools Teach Character Americas schools are having a difficult time simply teaching students how to be proficient in reading, math and science. Thats why many schools completely ignore teaching basic character skills. Most schools do not effectively teach behavioral skills and proper attitudes/manners like cooperating, being on time, making eye-contact, speaking persuasively, etc, argues Jay Mathews in an article in the Washington Post. Some schools are trying to incorporate these basic skills into education, a practice known as character education; however, many schools are still ignoring them. Very few schools have actually made progress in character education, argues Mathews. Mathews cited a study in social and emotional learning (SEL education) that trains students to act and think in positive ways. The study suggested that strong SEL education can create better student achievement. However, the data does not yet measure effects on students lives and work after high school graduation. Students in social and emotional learning classes improved their test scores and grades by 11 percent, compared to similar students in standard classrooms without SEL education, according to the Impact of Enhancing Students Social and Emotional Learning: A Meta-Analysis of School-Based Universal Interventions study, by Joseph A. Durlak and Kriston B. Schellinger of Loyola University Chicago and Roger P. Weissberg, Allison B. Dymnicki and Rebecca D. Taylor of the University of Illinois at Chicago. The authors of the study determined that these results were significant. They also found that students in SEL education have better social skills, less emotional distress, less misbehavior (bullying or suspensions), more positive behavior and ultimately better attitudes. These effects continued for six months after the programs ended. SEL programs are successful at all educational levels (elementary, middle and high school) and in urban, suburban, and rural schools, although they have been studied least often in high schools and in rural areas, reads the study, according to the Washington Post. The authors stated the SEL education helps students become more confident in their learning, and thus try harder and rarely give up on more challenging concepts or classes. SEL education students are also self-motivated, setting high academic goals and constructing a personal, effective approach to learning. Other studies are contradictory. One from the Institute of Education Sciences suggests that seven of the most popular SEL education programs did not produce significant social or academic gains. Another study, the Child Development Report, suggested similar results, also stating that SEL education does not necessarily produce better attitudes and behavior. SEL education produces better results in smaller classrooms, especially when a teacher takes on the approach for one class, according to Mathews. School-wide comprehensive programs are more complicated to implement, causing problems and limiting their positive effects.

Brasil, eventos e o Inglês

Brasil, eventos e o Inglês Com todos os eventos que o país irá cediar pelo próximos anos Copa das Confederações, Jornada Mundial da Juventude, Copa do Mundo, Olimpíadas é imprescindível que quem trabalha com o público tenha um conhecimento, ainda que básico, do Inglês. Isto, porque como se sabe, o Inglês é um idioma internacional, usado em todo o mundo para facilitar a comunicação entre pessoas de culturas diferentes.Foto: Márcio Luiz Rosa/ O Globo e Isabela Marinho/G1No entanto, com a proximidade destes eventos, vemos deslizes como o caso das placas erradas no Rio de Janeiro, que demonstram um descuido para com os preparativos. É certo que das 300 placas instaladas, apenas duas continham erros. Porém, tendo em conta da magnitude das atividades que o Brasil irá albergar, seria de pensar que, antes da instalação das placas, alguém que fale Inglês teria acesso às mesmas e fiscalizaria esse material, de modo a garantir que nenhuma gafe fosse cometida. Afinal de contas, o mundo inteiro es tá prestando atenção. Nesse caso em específico, o órgão municipal responsável garantiu que a reposição das placas com a grafia errada não iria gerar novos custos, mas o mal já está feito, a imprensa, nacional e internacional, já noticiou o acontecido.Existem diversos grupos que são contra a realização destes grandes eventos no Brasil, inclusive, ainda esta semana, ativistas formalizaram uma queixa de violação de direitos humanos contra o Brasil na ONU, por causa das pessoas que estão sendo desalojadas para a construção de infraestruturas para a Copa e outras situações consideradas abusivas. Sem falar que ontem (30/05), a justiça do Rio suspendeu o amistoso Brasil x Inglaterra, que seria no Maracanã, alegando falta de segurança para o público. Contudo, mesmo com todas estas situações, não existe nenhum indício de que algum dos eventos será cancelado. Portanto, estar preparado para a recepção dos turistas é um dever.Seja para quem trabalha diretament e com o público ou para quem irá chefiar equipes, que estarão lidando com pessoas de outras nacionalidades todos os dias durante a realização dos eventos, saber falar outros idiomas de preferência, pelo menos, Inglês é fundamental. Daí que esteja a ocorrer uma corrida às escolas de idiomas, mas os cursinhos intensivos não conseguem ensinar tudo, especialmente se você nunca teve um contato regular com a língua.Quem quer estar com o Inglês na ponta da língua precisa se preparar, seja com aulas intensivas de conversação, cursinhos de idiomas ou quaisquer outros meios disponíveis. No entanto, nessa busca por estar pronto na hora que tudo começar, é preciso ter em mente algo essencial: invistam em algo que seja útil no futuro, não apenas para os eventos, mas para a sua carreira como um todo. Não aprendam o idioma apenas para a Copa, aprendam para vocês mesmos, para as suas carreiras, para a vida, pois só assim o investimento valerá a pena. Boa sorte!

Working hours for UK Teachers - Tutor Hunt Blog

Working hours for UK Teachers Working hours for UK Teachers amongst the longest hours in the world Working hours for UK Teachers amongst the longest hours in the worldSchoolsA recent study published by the Global Teacher Status Index shows that teachers in Britain are working more hours per week than nearly anywhere else in the world. The global study found that UK teachers work around 50.9 hours per week ? that`s more hours than teachers in any other country in the survey, with the exception of Singapore, Chile and New Zealand. The study also polled members of the public, asking them how long they thought the average teacher`s working week was. The results came back at 45.9 hours, showing that most people grossly underestimate the time teachers work. I know from experience that some teachers work far more than this - my partner is a teacher, and certainly spends more than 50 hours a week at her school; and then of course there is all the time she works at home, marking students` work and composing lesson plans. I also know socially many teachers who work throughout London, and they all calculated that they exceed 50 working hours a week. Many people would say this is not a particularly excessive amount: if you want to progress in your career you have to be willing to put the hours in. I`ve worked in telecommunications, and the financial sector, and there were some years where I`m certain I pushed past the 60 or 70 hours a week. It was hard work, certainly, but I was determined to progress, to climb the ranks, and to be financially rewarded. In teaching however, there really is an upper bound on what you can earn. Unless you become a head of a school, your pay`s capped at a boundary far lower than you would ever encounter in the private sector. Despite their relatively low pay the study actually revealed the British public significantly overestimate the starting salary of teachers, believing them to be earning around ?29,000, when in fact a newly qualified teacher generally only earns around ?24,000. Somewhat hearteningly the report also indicated that the public think the starting salary of teachers should be far higher: around ?31,000. Back in 2013 a similar poll showed that more than three quarters of the public were behind some form of performance related pay for teachers. Opinions seemed to have changed during the five year interim though, with only a third of those being polled in the new survey supporting this kind of variable pay scheme. Getting back to the topic of long working hours though - unless you live with a teacher, I really doubt anyone could comprehend the amount of work their job demands. My partner is a science teacher in a London secondary school. She`s at work every weekday for 7:30am, and rarely leaves before 5pm - this schedule in itself is not particularly onerous, but at least once a week there is some kind of extra activity, such as a parents evening, or some kind of meeting, which usually continue past 9pm. Added to this is the gargantuan amount of work that she does at home: planning, marking, lesson plans - this prodigious amount of paperwork (and our home is full of paper and files and textbooks) is attended to every evening, and for a large portion of the weekend. An obvious counter to the claim that teachers are grossly overworked is that they are compensated with a huge amount of holidays - typically around 13 weeks annually. No one can deny that this is a very generous amount of holiday le ave - but I can tell you that for a portion of every break, summer, Easter and Christmas, my partner spent a significant amount of time working at home. Many teachers complain that they spend as much time being in-school social workers, dealing with unruly pupils, as they do actually teaching. Only this week the department of education has pledged to assist schools in this area, promising that they will simplify the way teachers are required to log and record poor behaviour. I suspect that the teaching profession is becoming hampered by the same bureaucracy that the police force is suffering from: being required to create encyclopaedic logs of every incident, and every single misdemeanor, however large or small it is. The Department for Education have just published a report by the Workload Report Advisory Group, which cautions how teachers are at risk from `anxiety and burnout` due to the growing about of paperwork relating to pupils` behaviour. We rely on teachers to produce every new generation of employees - if we put them under too much pressure, if we obstruct their ability to actually teach, and fill their lesson time with excessive bureaucracy, we will be directly reducing the quality of education our future workforce will be receiving. 15 months ago0Add a Comment

The 4 Best Cities For Startups Other Than San Francisco

The 4 Best Cities For Startups Other Than San Francisco Image via (Uplifted.net) Located nearest to Silicon Valley of all four cities, Seattle has a large and early influence from North California. Companies such as Starbucks and online retailer  Amazon  were initially established in the area. Connections to tech and entrepreneurial talent have produced many startup businesses. The state does not have an income tax, which is good for residents. Although the cost of living is high, income rates are reasonably high as well, making it a more affordable option than the San Francisco Bay area. Proximity to the Pacific Ocean and mountain ranges are always a welcome distraction from busy city life. Seattle’s welcoming community also offers original cafes, reading gatherings, and massive public fountains to cool off in the summer. Austin Image via (Uplifted.net) Texas likes big, and so does Austin. The state’s capital is home to young adults and entrepreneurs who enjoy the nightlife, music festivals and outdoor fitness. The city promotes itself as the “live music capital of the world” for its many music venues and concerts, as well as “Silicon Hills” for its increasing presence of tech companies. Residents unofficially adopt the slogan “Keep Austin Weird” to describe the diverse and accepting crowd. Innovation-influencing festival South by Southwest is a major attraction to tech developers and investors, film producers and critics, and up-and-coming and well-known artists. Stephanie Walden reports that the city “ranked first in the Kauffman Foundation’s Startup Activity Index for 2015.” The city also solves San Francisco’s issue of affordability with its low rent rates and real estate pricing. Baltimore Image via (Uplifted.net) The northeast city of Baltimore has seen major growth over the last couple of years. The initial industrially-employing town is looking to transition into a tech economy. The Downtown Partnership of Baltimore is also incentivizing startups and companies with $10,000 grants through the TechConnect program to move into the city’s center. Its location is the perfect business center for startups and companies. The attraction of the harbor and proximity to other businesses has interested established companies like American Technology Services that are now opening offices in the center of the city. Miami Image via (Uplifted.net) If you’re seeking a complete change of environment, South Florida’s white sand beaches and endless nightlife offer a fun atmosphere for entrepreneurs. The city’s downtown region is renovating its buildings and creating workspaces for potential startups to launch. Perhaps the biggest incentive for companies is that the state of Florida does not impose many taxes such as income, property, or investment taxes. Miami is also rich in Latino and Caribbean culture with globally-influenced food spots, modern and urban art and entertainment.

Unisa Tutoring - What Is It?

Unisa Tutoring - What Is It?Unisa tutoring is a wonderful service that does not exist anywhere else. Many parents have come to us because they do not have the money to pay for the tuition of their child or children, but still want their child to be tutored by qualified teachers and many teachers would also like to offer this kind of assistance.Tutoring is offered through the school and usually within the school structures in various states throughout the country. This makes it convenient for you if you live in one state but want your child to be taught at a school in another state. It is a very common method to take your child to a home for tuition or maybe even an adult school where you can be taught in a different environment as well.Unisa tutoring is very similar to professional tutoring. You will find the tutor available either by phone or on a weekly basis. The main difference between this type of tutoring and the other is that, there is no specified time for teaching the studen t. You are free to schedule your own days to teach your child and often times they are learning at home too!Parents may be concerned with how much time their child spends learning. They do not necessarily see this as a negative aspect of learning because they feel it is great fun to allow your child to learn at their own pace. There is also the freedom to move around when you need to which means you can leave the classroom for a period to go out shopping or a friend's house. And of course you can schedule your child's education when and where you choose and the fact that they can be taught in the privacy of your own home is a bonus.Parents and teachers often make the mistake of thinking that the educational process should all occur in the classroom, however this just does not happen in many instances. Often times this is because the teachers would rather have a little break than students in the same room. It is also just not possible to teach in one room, especially at first.Many pr ivate tutors who offer this service also provide special services such as audio or visual aids, however the teacher will meet with the student once or twice during the academic year to discuss the learning objectives and goals. Of course your child will then receive feedback from their tutor and sometimes it is also beneficial to talk to your child about the lessons and their progress.Tutoring should not be thought of as a luxury service as much as a stress reliever. If you are trying to provide all the schooling that your child needs and it is getting to the point where your child has become bored and this causes you to want to sit them down and say 'can we do something else today'. Unisa tutoring is one of the most popular ways to relieve this stress, and you might be amazed to know that this kind of service can really help to raise a child's self esteem as well.

What Is A Chemistry Curriculum?

What Is A Chemistry Curriculum?At any age, there are very good reasons to start a course in Chemistry curriculum. If you do not have any prior knowledge of chemistry, it is possible that you could be a very successful individual who will be able to build and run a very important company, or even take your place on the field of medicine. For those that are interested in science, it is definitely an excellent career to pursue. There are many schools today that offer a Chemistry curriculum.There are many different types of curricula out there for the subject matter. Some offer a very broad curriculum with one of the few classes on the list being a very general chemistry class. This allows students to choose which topics they want to take. Other schools offer much more intense topics and choose a very wide list of subjects. The point of this type of school is to prepare students for a more advanced school with some major topics of their choice, but everything else being the same.Some of the other types of Chemistry curriculum are required by all students of Chemistry. These schools will usually provide students with a very comprehensive test to determine if they are ready for this type of education. Students will often receive an amount of high grades on these tests in order to take more tests and be prepared for the classroom experience.Students that have taken a better understanding of the subject matter will often find that they are in demand in the field of science and medicine. For this reason, there are many high schools now that offer a Chemistry curriculum.Every single one of us at some point will have had a particular science class that made an impact on our life. Even if you don't understand the subject matter, it is possible that you have come across the term 'natural science' which is a general term for the study of chemistry. If you are at school right now, you may want to consider taking Chemistry in high school. It is definitely an option that can he lp your career, as well as giving you a great starting point when you begin.Chemicals are really the basis of life and have an incredible effect on the growth of the world around us. For this reason, understanding the process of how they work and what chemicals are is very important. There are many schools that offer a Chemistry curriculum in high school. It is always good to make sure that you know what you're looking for and what kind of school is going to work best for you before you commit to a certain school.Finding a school that offers special Chemistry is extremely important because there are many ways that people become confused when it comes to Chemistry. While it is generally known that Chemistry is the study of the chemical structure of substances, this is not the only type of Chemistry that exists. In fact, there are actually several other forms of Chemistry that exist, each focusing on a particular topic of study. This is why it is always important to find the proper sc hool for your particular special interest.

Organic Chemistry and Solution Manuals

Organic Chemistry and Solution ManualsThis is the third edition of Janice Smith's Organic Chemistry and Solution Manuals. This title is now in its third printing and there are no reviews on it yet. The third edition covers all the topics that were introduced in the first two editions with some new material.Janice Smith introduced these, as a gift to her students to help them with their chemistry homework, but they have more features than just being a chemistry book, she actually created a series of course projects that the students can follow for practice and learn from. There are problems, labs, quizzes, and the labs are put in every chapter of the text.I think it is great to have a Chemistry textbook that is geared towards an online learning system. You can take notes at the same time and even do online homework or projects at the same time. Also there are not any homework, projects, quizzes or tests in this book, that will affect the scores in any way. There are other materials li ke the class assignments are due before you can start your course.One of the best things about Organic Chemistry is the lab where you can study the solution to the experiment. There are actually also online labs that you can use to practice and see what the solution is, by yourself. These are put in every chapter of the text for quick reference.Janice Smith offers detailed explanations for all the chemistry topics. One thing that struck me about this text was that the pre-exam review chapters were actually listed right at the beginning of the book, as if it was a bit of a guide. Some of the chapter headings go into great detail about what you need to know for your pre-exam study session. One of the most recommended courses that Janice Smith has made available is called 'Becoming Scientific'. This is a way for you to better understand how the scientific method works, how different experiments are done, the different types of experiments, and how the basics of chemistry apply to them. Overall, Organic Chemistry is an interesting book. If you find yourself struggling with Chemistry, this is a great read for you to get a refresher.
