Chemistry - Answer Key

Chemistry - Answer KeyThe theory behind the answer key is really simple. All you have to do is take a look at any piece of chemistry text and you will discover that there is a few basic operations that are followed to solve a given problem.The key for solving the problem is the combination of these basic operations, which are called the 'operation'. When you translate the idea of an operation into a key, it sounds similar to a tennis player who is trying to find the best combination to hit the ball. Of course it is more than just that.Chemistry has lots of problems, and each one of them requires a different answer. Even the standard operations, such as polar and partial polarization are open to alternative solutions, but the key is always the same. The key is the combination of operations. That is why the question is so important.In chemistry, there are many different molecular orbitals, and each one has its own function. However, all the operations can be carried out by a single sys tem, which is the molecule. An illustration will help you understand.If you drop several single molecules onto a t-shirt, the arrangement of their orbitals would allow the molecules to form a cluster that would generate heat from the body heat. However, if you dropped dozens of single molecules on a t-shirt, then a different arrangement of orbitals would cause them to form a different cluster. The cluster would absorb heat from the body, resulting in a different temperature.It is the combination of operations that is important. They must work together to get the required result. If there is an operation missing, then the result will not be the same.Chemistry is really exciting. It is a science that look at the properties of atoms and molecules and tries to find out how they combine to create new things. A better understanding of chemistry will lead to new materials and new technologies. The key to success is to remember that the answer is everything.

italki presented at the 2014 SouthWest Conference on Language Teaching

italki presented at the 2014 SouthWest Conference on Language Teaching Erin OReilly, one of our Professional Teachers who has been teaching on italki for over a year now  recently presented Going Global: Using italki to Connect with Native Speakers at the 2014 SouthWest Conference on Language Teaching in Snowbird, Utah, USA last month. We were honored that she presented on  our behalf.  Below she shares her presentation with a guest blog post: The Changing Language Classroom April 24-26, 2014 by Erin N. OReilly Language teachers  love technology.  Arguably, they probably love technology more than teachers from most of the other traditional subject areas.  This may be because until the advent of the Internet, getting authentic language learning materials meant travelling abroad and schlepping back yellowing newspapers, outdated magazines, and bulky cassette tapes.  Talking with native speakers?  Never a possibility unless you lived in a major metropolitan city. For the past year, I have used the italki platform as a language teacher, connecting with language learners and enthusiasts around the globe. While their goals and reasons for learning a language vary widely, their passion and enthusiasm to connect with native speakers is immediately obvious. Enter italki â€" the platform that makes it all possible. This past week I had the opportunity to join with language teachers from around the South Western region of the United States at an annual language teacher conference. I shared with them the research behind live, online language lessons as well as best-practices and creative ideas to get started. As language teachers, we’ve historically been limited to classroom learning. Creating opportunities for meaningful practice with native speakers has always been limited by geography. Today the tools exist to go beyond the classroom, to connect with a world of learners and teachers. However, breaking out of the classroom mindset to engage with the language authentically and on a global scale is not something that language teachers naturally consider when designing or delivering their language courses. Looking forward, I challenge the classroom language teacher to experiment with ways to build and integrate global friendships, partnerships, and connections into the traditional curricula. As one conference attendee commented, “Wow! They’re using real language.” And this is what language learning is all about! “Wow! They’re using real language.” And this is what language learning is all about!

Dont Even Think About Leaving Your Dorm Order Food Online!

Don't Even Think About Leaving Your Dorm Order Food Online! pexels.com Find Local Restaurants The locavore movement has been steadily picking up steam, especially across college campuses nationally. A locavore is usually someone whose diet consists only of principally locally grown or produced food but it does not have to be limited to that. This movement also means supporting mom and pop-like stores, restaurants that are local to your college town and do not exist anywhere else. You can always order from the national chains that exist in every area but you can also often type in your zip code and see which restaurants directly in your area are still open and that you can order from. You can support the businesses that you are interested in! Variety of Options When you order food online, you have myriad possibilities of where to order from. Any restaurant that offers food delivery is fair game. And there are so many different kinds of food cuisines to choose from! Want Indian? Chinese? Japanese? American? A combination of all four? Whatever cuisines your city has to offer you can most likely order online and have delivered to your house. And you can order different items from different menus and have it all delivered to your doorstep. Get exactly the food that you want to eat. Get Coupons/Specials Ordering online can provide you with another perk as well: coupons and special deals that you otherwise would not get. There is almost nothing as satisfying as typing in a coupon code and seeing your total amount dwindle down. It might be dependent on the restaurant(s) you are ordering from or the online service through which you are ordering your food but often enough you can find a way to get that price dropped in a way that would be impossible if you were ordering on location and in person at the restaurant itself. pexels.com Order For Free Many online ordering services will allow you to order your food online without adding any charges. There are no hidden fees or the extra effort taken by the restaurant and service driving up your final price. You just get to do you, ordering the food you want, affording it, and eating it. And that is the best part, right? Convenience One of the most obvious but underappreciated perks of ordering food online is the convenience it affords you as a consumer. All you need is an internet connection and presto, blammo, you have got food on the way! You do not even need to turn on your laptop or computer your cell phone will work just as well. You can also have your food delivered to you, no matter where you are. Obviously you need to be within a reasonable distance of the restaurant but besides that it can be free game. Having a late night cram session in the library? They can meet you on the library steps. Home late from a party and craving a particular kind of food? They can bring it straight to your dorm. In a late night rehearsal? They can bring the food wherever you are rehearsing, whether it be the theatre doors, the music building practice rooms, or more. It allows you to feed yourself in situations where you otherwise or usually might have been forced to go hungry, unable to get food while you are otherwise occupied. And if the weather is poor, guess what? You do not have to be the one to go out in the pouring rain to get your food. Some poor, hapless delivery driver will bring your food directly to you while you lay toasty and warm in your bed. But remember to tip your delivery driver well for your convenience!

What is the Year 1 Phonics Test

What is the Year 1 Phonics Test We all know how important it is for children to learn literacy. And early learning of the phonics has become a very important part of a child's reading journey. The Phonics Screening test was first launched by the Department of Education in June 2012 and schools will administer the test the week beginning 13 June for this year. The test is defined by the Department of Education as short, light-touch assessments that usually take between four and nine minutes for each child to complete. The Phonics Screening Check The Phonics test or Phonics screening check is compulsory for all year 1 children and is used to determine whether they have learnt phonic decoding to the proper standard. It identifies children that may need extra help in improving their reading skills and allows the school to step in and make sure these children meet the appropriate standard. The test itself consists of a list of forty words which the children read to a teacher and tests the ability to use letter-sound knowledge to correctly read and pronounce written words. The words used are twenty real-words and twenty non-words (made-up words). The reason for the non-words are so that there will not be a bias to those children with a good vocabulary. The non-words are shown alongside a picture of a fictional character and the children are told that the non-word is the name of that fictional creature or character allowing children to understand that the non-word should not be included in their existing vocabulary. Children who are able to read non-words should have the skills to decode most unfamiliar words. Phonics knowledge is taught to children from Reception class helping them to recognise and read familiar words and to be able to read words that are completely new to them. They learn about the way graphemes (written words) relate to phonemes (spoken words) and how to sound out the words. The International phonetic alphabet The following table shows the International Phonetic Alphabet that is used to explain the pronunciation of pseudo-words used in the Phonics Screening check for year 1 children (words that are not included in the test are in red whilst the words in blue indicate that the grapheme-phoneme correspondence only applies to certain regional pronunciations): Consonants Vowels Phoneme Example Phoneme Graphemes /b/ bad /??/ father, arm /d/ dog /?/ hot // this // cat /d?/ gem, jug /a?/ mind, pie, high, fine /f/ if, puff, photo /a?/ out, cow /g/ gum /?/ hen, head /h/ how /e?/ say, came, bait /j/ yes /??/ air /k/ cat check, key, school /??/ cold, bone, coat, mould, blow /l/ leg, hill /?/ hit /m/ man /??/ beer /n/ man /i?/ he, bead, see, scheme, chief /?/ sing /??/ launch, raw, born // both /??/ coin, boy /p/ pet /?/ book, cup, could /r/ red /??/ tour /s/ sit, miss, cell /u?/ stew, room, you, blue, brute /?/ she, chef /?/ cup /t/ tea /??/ fern, turn, girl /t?/ check /?/ farmer /v/ vet /w/ wet, when /z/ zip, hens, buzz /?/ pleasure Source: satpapers.org The Threshold and results In 2012 when the first testing began the threshold was 80% and continues to be around this mark. This means that children need to correctly identify and read 32 words out of the total 40 words to be considered to have met the necessary standard. The test determines whether children are correctly able to identify sounds associated with different letters, and letter combinations, and consequently blend these sounds together to correctly say the word on the list, regardless of whether the word is a real-word or a non-word. The combinations of the letters become more complicated as they move down the list of words meaning the words become increasingly harder. The threshold mark is conveyed to schools usually at the end of June so that teachers can then mark the test. Parents are then informed of how their child did although the results are not published. If a child fails to meet the standard they are given extra help in their phonics understanding and can then retake the test in year 2. What can you do to help? The best way to ensure your child will meet the standards of the phonics screening check is to enhance their vocabulary. Read new books with them and introduce them to new vocabulary. Play word games with them and make sure they are correctly sounding out the words. There are plenty of free resources for practising phonics with your child; the Schoolrun website offers some great information and the Department of Education website offers more information and some practice assessments. A private tutor can also be a great help in aiding your child's learning of the phonics.

Why You Should Take A Hot Bath

Why You Should Take A Hot BathHot water baths are not so unlike cold baths. And that's good news because they can be used to lower your cholesterol and lower your blood pressure. The reason they are used to help in these two areas is because of the different chemical changes when heated water enters your system. That has been scientifically proven by research over the years.At the time when you take a warm shower or take a hot bath, you are using a lot of heat to get you through the day. But, when you take a warm bath, you don't use as much heat. That's why taking a warm bath can lower your blood pressure much more than you could possibly imagine.In fact, a lot of the medical research about lowering your cholesterol using hot water has shown that after you take a warm bath, your body is able to make a couple of molecules of dihydrotestosterone (DHT). DHT is a hormone that is known to be linked to heart disease.When you use hot water in a hot bath, the dihydrotestosterone can be flush ed out of your body and the chemicals in your blood are cleaned. When it comes to cleaning your body, your blood vessels are probably the first thing that come to mind.Because your blood vessels are clean, they are now getting better oxygen as well as nutrients. Oxygen and nutrients to help in your fight against those nasty molecules that contribute to your cholesterol issues. The substances in the hot water helps clean out those cells that are clogging your arteries.After you take a hot bath, your body also becomes cleaner and more efficient at removing those impurities that may have settled on your skin. These impurities are now helping the body get the blood it needs to run efficiently. If your body has all the nutrients it needs to heal itself, then you are less likely to experience muscle cramps or other types of problems.So if you are thinking about taking a hot bath or shower, try to do it right after a nice meal. That will help your body to flush away the impurities and it w ill cleanse you of the cholesterol you have.
