Calculating Uncertainty in Chemistry

Calculating Uncertainty in ChemistryWhat if we could learn the methods to calculate the uncertainties for each and every chemical reaction? Would it help you make more accurate calculations?The first thing that is important to understand about the way in which people are measuring changes in temperature is that they are using the Fahrenheit scale. In the scale known as Celsius, the term for degrees Fahrenheit is Celsius. In reality, a measurement of temperature and a measurement of change in temperature are not the same thing.Celsius measures the amount of temperature change that occurs per degree of change in temperature. Therefore, the temperature change per degree of change in temperature is what is actually measured by a person using the Celsius scale. When you adjust the scale to convert between Fahrenheit and Celsius, the temperature units are still actually measured in Fahrenheit.The reason why this is relevant is because for many different chemical reactions, this is how they occur. If we could understand the values for these different values and calculate them out for all possible combinations of reactions that could occur, then we would have a much better understanding of how these chemical reactions work. What you would be able to do with that knowledge would be much better than blindly taking temperatures and rates of change of changes of temperatures.What are some of the potential problems that could arise from calculating out the values for different reactions? I won't tell you the ones I know about, but there are probably dozens of possible problems that could arise if we did this. There are many good resources out there that can help you with this, so be sure to look into them.However, let's get back to our discussion about how we calculate Celsius in our chemistry calculations. What is it that you will find the most valuable information in this process?The best method for measuring Celsius temperature changes, using standard methods, is to make a chart that uses temperature measurements from the different points in the scale. In this chart, the various values will be written in the order that they occurred. For example, say that there was a step in a product made with a specific amount of HCl and ammonia and one where there was a doubling of the content of that substance. In this example, you would want to know how much ammonia the product was capable of producing with each step up in temperature.

Pattern-Making Basics for Fashion Design

Pattern-Making Basics for Fashion Design Mastering Fashion Design Basics: Pattern-Making ChaptersWhat is Pattern Making?How Can I Make My Own Dress Pattern?Where Can I Learn to Make Patterns?How to Adjust My Patterns?Where Can I Buy Sewing Patterns?There is simply no way around it: for humans, clothing is essential.So is looking decent â€" not that your Superprof is deeply concerned about appearances but, in these times so dominated by social media influencers, looking shabby is looked down on.The idiom The clothes make the man  has never been truer!Doesn’t that make you wonder why the clothing industry seems determined to only outfit people of average height and weight?It’s true! If you are tall, more than, say, a size 16 and/or irregularly shaped, you have to either shop for clothes at speciality stores or resign yourself to an ill-fitting wardrobe. Unless…Unless you know how to sew, in which case you can make all of the clothes you want, tailored to your exact measurements.Of course, you could always go to the dressmaker’s or tailor every time you need a wardr obe addition but have you seen the price of bespoke clothing?That is a great reason for you to engage in dressmaking â€" or tailoring, if you are male.Other great reasons are that you have a unique sense of style that you would like to express through your clothes, you are interested in fashion but not quite sure you want to make a career out of it, or you might be looking for a new outlet for your creativity.Whatever your reasons for entertaining the idea of home sewing, we applaud you.So, whether you are a student contemplating a career in fashion design, looking for your next ‘new thing’ or fed up with clothes that never seem to fit right, it’s time to gather ‘round.Your Superprof is about to tell you all about pattern-making and how you can make it work for you.

Clothing patterns start with a sizing template called a sloper Image by Maatkare from PixabayHow do patterns get made?Basically, it all starts with a sloper â€" a block, in industrial terms.A sloper is an unadorned template that pattern drafters use as a guideline to draw patterns; you might think of them as stencils.Most garment makers have several slopers/blocks: a top and a bottom for menswear â€" for shirts and trousers. For women’s apparel, they would have a top, a trouser and a skirt sloper. Both male and female slopers come in a variety of sizes.When it is time to draft a new pattern, the pattern drafter selects the appropriate sloper, traces it on pattern paper and then starts marking it with solid lines for the garment outline and dashed ones for the seam allowance.S/he then goes on to include notches to match the panels up; darts and pleats if the design calls for them. They will also draw in pockets, buttonholes and, if the garment is supposed to be ruffled, s/he will dr aw in the ruffle placement.Much like house builders follow blueprints, dressmakers use patterns to ‘build’ clothing. In that sense, you might call pattern drafters the architects of the garment industry.Now, find out if pattern making has always been so prevalent…How Can I Make My Own Dress Pattern?Perhaps, as a child, you loved to sit around on rainy days, colouring pad on your knees and pencil gripped tightly in your hand. What did you draw?It’s not uncommon to engage in fanciful drawing at a young age so, if you drew knights and warriors in full battle dress or maidens in shimmering gowns or a tunic dress, you already have an idea of what it takes to plan a pattern.You chortle: “It’s a far cry from a child’s drawing to pattern drafting!” We beg to differ.Would you be surprised to know that legendary designers like Coco Chanel and Karl Lagerfeld never went to art school? And Michael Kors dropped out after only nine months. What did they do that you can’t?Whether you have an art education or not, the best way to start a dress pattern is to visualise it. Will it be a maxi dress? What fabric will it be made of? Will it have any embellishment â€" bows or ruffles? What about the bodice?How about dreaming up an open-backed summer dress?Once you have a good idea of the dress you want to make, sketch it out in as much detail as you can… and then, explode it.To get those explosive details, you have to read our step by step account of pattern drafting to learn exactly how to make that dress pattern. Store-bought patterns are pre-cut but, once you start making your own patterns, a rotary cutter is a must! Image by Gábor Adonyi from PixabayEventually, you too may mass-market the patterns you make but, for now, focus on making one-sized patterns; patterns to your measurements.To make your own patterns, you will need:a roll of pattern paperpencils and coloured pencils; having a rubber handy is a good ideascotch tapea tracing wheela 30cm see-through straightedgea French curve (you may also consider a Vary Form curve)an L-squarea fabric tape measurescissors or a rotary cutterIdeally, you should have a large table to work on; a sewing table with lines imprinted on it would be aces!As you might have noted from the shopping list above, you don’t necessarily have to have an artistic hand to guide your pattern drawings; most every mark you make will be guided by a straightedge or a curve.Now that you’ve got your shopping list, you only need to discover the best places to learn pattern making.You may choose between open sewing courses hosted by your local university or college, head to the library to check out some sewing books, or you could take a course in pattern making online.Don’t forget to stop by your local sewing shop to see if they offer courses, too!How to Adjust My Patterns?It’s a paradox: the clothing industry should cater to its buyers; if they don’t, people will simply stop buying… right?Wrong! For years, garment factories have been turning out cookie-cutter clothes that fit only averagely-proportioned people.  Curiously enough, it’s been only recently that the industry has conceived the idea that not everyone fits in a standard size.Thanks to independent designers with a strong online presence, activists and ongoing social media campaigns, there is a growing awareness that limiting sizing is seen as discriminatory.Those are steps in the right direction. Unfortunately, they are baby steps because it simply is not profitable for garment com panies to make a greater range of sizes.Where does that leave those of us who do not fit in that average mould?For the most part, we are still altering the clothes we buy and making our own clothes if we know how to adapt a pattern to our unique body type.You might think that messing with a professionally drawn sewing pattern is a recipe for disaster but, if you follow the hacks we outlined to adapt your patterns, you will marvel at your success in turning out that cute skirt or wrap dress in time for your next night out! Unlike many free patterns you can download, store-bought patterns provide a range of sizes Image by Katja Kuitunen from PixabayWhere Can I Buy Sewing Patterns?Of course, there is nothing wrong with buying a Simplicity or Butterick pattern, especially if you are just starting down the road to making your own patterns and/or designing your own clothes.In fact, it would be a good idea for you, at the outset, to work from patterns so you can get the feel for them.The big names in dress patterns â€" the two mentioned above and others, like Vogue, Lookbook, Kwik Sew, New Look and Burda Style pretty much all follow the same guidelines in making their patterns.Each pattern envelope offers the possibility of up to four designs and comes with instructions, sizing guidelines and, more often than not, fabric recommendations.You might know that not every fabric flows and falls the same way, and some are decidedly more difficult to work with than others.In that same vein, we might say that not all pattern makers are the same, either.For instance, independent designers offer free sewing patterns that you can get as a PDF download; they are a lot less 'crowded' than name-brand patterns you find in stores.Whatever you decide, perhaps it would be best if you spent some time in your local sewing shop, talking with people who have experience in the needle arts.They may be able to give you some pointers on the best patterns for beginner sewing; they may even offer you sewing tutorials.If you’re not sure where your local notions shop is, you may refer to our full-length article on the subject; if you’re certain there are none near you, surely you have a Hobbycraft store somewhere close.Those shop assistants may not be as knowledgeable as an independent shopkeeper would be but, rest assured: Superprof has sewing tutors if you need a sewing tutorial…

10 Free Physics Resources for Teaching Kids

10 Free Physics Resources for Teaching Kids This is a guide for the best online physics resources, many of which I used when learning about physics, and one of which I still use for revision myself as I study at Imperial College London. So, in no particular order . . . . 1. This first website is from the Institute of Physics and is great for learning about lots of aspects of physics. I especially like the teaching astronomy section which features fantastic videos for  11 to 16 year olds and  are great at  grabbing the imagination of kids. One of the key questions tutors are asked is “how can I get my son/daughter excited about science.” Well I say start here! 2. The Physics classroom covers a lot of key physics material that is certain to come up in exams. I particularly like the introduction to  waves by the folks at the Physics Classroom. More advanced students have plenty of scope to learn much more as they become interested, which is perfect for continuing their interest. Good to note that it is also available on iBook and iPad. 3. Providing resources for 9 to 11 year olds and perfect for help with the 11 plus,  Topmarks  is designed with fun colourful games to engage kids in learning about science and hopefully enable a continued interest in science. I have linked a game that teaches about solids, liquids and gases but you can search the site for other interactive games. 4. This is a fantastic GCSE physics site  from myPhysics that goes through each topic covered in GCSE. It’s highly interactive, colourful and easy to use. There should be an A level section coming soon which I am excited about. 5.  GCSE.com   (purely for GCSE surprisingly!) has lots of past papers and also resources to look up material when stuck. Perfect for making sure you have covered everything. They also provide some very simple, explanitory diagrams that hopefully should give a slightly new way at looking at topics. These diagrams may well prove more intuitive for your child.   Well worth a look. 6. I love the schoolphysics website  for its fabulous animations that  illustrate key physics ideas. There are an extensive number of them and they are all very simple and easy to use. If the animations aren't enough there are also thousands of other pages with beautifully laid out content for 11 to 19 year olds. I would particularly suggest anyone wanting to study physics at university to have a look over any content that hasn't be covered in the A level course. 7.  Discovery Education is great for tutors and teachers, as the site has full lesson plans for different topics. Well worth a look through if you find yourself getting stuck on how to approach a topic. 8. Created by Kishore Vyas, a science teacher in West London, My GCSE Science  has a video for every GCSE science topic.   All the videos are clear and, most importantly, designed specifically for the GCSE candidate in mind.  It has foundation videos and then more advanced videos, meaning that the explanations are always pitched at the right level.  Fantastic looking website too! For offline tuition  and inspiration why not head to the Science museum in South Kensington! 9.  Science teachers provides complete worksheets that are engaging and different. Very useful for teachers or tutors.  I find the most important thing when teaching kids science is presenting the material in many different ways. These worksheets are great for that. 10. My list would not be complete without mentioning the wonderful Khan Academy. It started as a way for Khan to teach his niece through videos  he uploaded on YouTube, but before too long they  spread across the world.   I’ll let the videos speak for themselves. If you are looking for extra help, why not try physics private tuition. Find the right tutor for you with Tutorfair. Happy learning!

An iPod worth $8 billion English Listening Exercise

An iPod worth $8 billion English Listening Exercise I think one of the hardest things understand in English, or in any language you are learning, is humor, and especially more subtle humor, like sarcasm.

How to avoid cold feet The teach abroad edition

How to avoid cold feet The teach abroad edition Feeling anxious about teaching abroad for the first time? I know the feeling, trust me. When I first made the decision to move to Australia to teach and throughout the entire application, interview and offer process, it never occurred to me to feel afraid or nervous. It wasn’t until I broke the news to friends and family, and started making concrete plans for departing, like booking flights and organizing packing, that I started to feel those first stirrings of unease. And as the day of my flight loomed closer and closer, I realized that I had officially developedcold feet. I’d traveled around to different countries before, but this felt like a whole different ball game. It struck me that I would be moving abroad - totally alone - for a significant period of time. To say I started feeling just a little nervous, right before it was time to depart, is a bit of an understatement. It’s important to remember that fear is a completely normal, human reaction to the prospect the great unknown. While it’s impossible to totally shake away all those nerves, here are a few ways to ease yourself into your new journey teaching abroad and start getting excited about your new life adventure again! Do your research The scariest part about moving abroad is facing the unfamiliar. Based on my experienceteaching English abroad on three separate occasions, one thing I’ve realized is that it’s always a good idea to plan ahead as much as possible. Google is probably going to be your main source of information, like it was for me. From informative articles (the Teach Away blog is a great starting point), to blogs written by teachers who also teaching abroad (check our blog roundup of some of our favorite bloggers teaching abroad), there’s no shortage of helpful information on what it’s like living and teaching abroad for the very first time out there. Learn about the culture There will, of course, be some social norms that are completely unfamiliar to you right off the plane. That’s why it’s worth reading up on these in advance. The more you know about your new country when you arrive, the better your transition will be. Finding out more about the customs and cultural norms of your new home will not only make you feel like less of a tourist. It will also help ease your mind and make you feel like a part of the local community. Learning a few common phrases will go a long in making you feel a little more prepared when you first arrive, too! Talk to other teachers who’ve been in your place Maybe a friend of a friend has taught abroad before and can offer some advice to help put your mind at ease. Don’t be afraid to reach out to other teachers on teach abroad forums about anything that’s worrying you, either - they’ll be more than willing to share tons of practical advice to help relieve your worries! Sign up to Teach Away today for access to the latest teaching jobs around the world. Don’t let a fear of failure (or FOMO!) hold you back Moving abroad is a big decision and it’s easy to anticipate all the ways that things can go wrong. Maybe you’re worried about finances, homesickness, missing out on important occasions back home...the list goes on! It’s totally normal to start doubting yourself. But don’t put too much pressure on yourself this early on. There will be hiccups along the way, especially right at the beginning while you’re still finding your feet. Just remember, moving abroad to live is an experience and you need to treat it like one. Be open to change and ready to try new things. Turn that nervous energy into productivity You’re moving to a brand-new country with your job already organized - you won’t need to scrimp and save as much as if you were job hunting on arrival. Exciting times are coming, so it’s time to channel those nerves into planning all the fun things you want to do once you arrive at your new teaching destination. Make a list and start planning out your free time. What are your favorite hobbies? If you’re a yoga buff, a book lover or sports fanatic, for example, start researching yoga classes in the area you’ll be living or look up book clubs or sports teams you could potentially join. Moving abroad is also a great way to shake things up a little. You can even start afresh and pick up a brand-new pastime - try a cooking class or trampoline lesson - even ultimate frisbee! Finally, remember all the reasons why you wanted to start this big new life adventure in the first place. You’ve put in a lot of time and hard work to get this far, so give yourself a pat on the back and allow yourself to feel that sense of excitement and accomplishment all over again. Take it from someone who ended up going abroad to teach on three different occasions - you won’t regret it! What’s your biggest fear about teaching abroad for the first time? Let us know in the comments below!

5 Reasons to Take Time Off Before a Postgraduate Degree

5 Reasons to Take Time Off Before a Postgraduate Degree Each and every year there are loads of graduates that apply to do a postgraduate to begin attendance in the following autumn. However, there are several reasons that you may want to take time off before making a decision. Ensuring you are making the right career choice By waiting a year or even two years before attending applying, will help you clarify your career path. You may choose to work in the field at an entry level position to see if this is something you truly want to spend the rest of your life doing. Gaining experience now for better learning later. There are many people out there that find it easier to learn in a class setting when they have real-life experience they can relate to or connect with. For instance, if you need to take epidemiology class for your degree, consider enrolling as a volunteer in the medical sector. You may end up in another country helping the people in the village comprehend basic health principles. This experience will make learning epidemiology topics easier. You will also gain knowledge that will provide you with insights that your classmates may not have. Improving your applications There are some degrees out there that only accept a small percentage of those who actually apply for admission. The admissions personnel will look at everything from your CV to personal and professional goals to grades to test scores to decide whether or not you are admitted. So, the more work history you have on your CV, the more realistic your professional and personal goals are and the better your grades and test scores are, you will have a better chance of being admitted. Improve your future job applications For a minute, pretend you are the hiring manager for your dream job. You have a pile of CV's and job applications in front of you on your desk. Half of these CV's have postgraduate degrees that are pretty impressive along with summer internships. The other half of the CV's provide detailed accounts of the applicants work history along with impressive skills that are relevant to the job and grad degrees that are impressive. It is pretty obvious that you are going to want to interview the latter group of candidates. Improving your outlook financially While it is true that postgraduate education may help you to increase your potential work earning, you can also improve your financial outlook before even deciding on a postgraduate degree. You can take a year or two and work so that you can pay down your student loan debt or you can begin to create a savings nest egg for your future.
