Definition of Oxidizing Agents

Definition of Oxidizing AgentsOxidizing agents are organic compounds that react with the oxygen in an organic substance and break down it to its constituent elements. The oxidation process can be performed chemically or it can be accomplished through physical processes. Depending on which method is used, oxidizing agents will be included in many scientific procedures.An oxidizing agent is simply any chemical or organic compound that reacts with the oxygen to form water, carbon dioxide, or a combination of the two. Water, carbon dioxide, and a combination of the two are known as condensation products. Both water and carbon dioxide are liquids and gases that are non-toxic, inert, and non-combustible. These substances are commonly used in preparing fuels for vehicles.A unique catalyst, such as hydrochloric acid, is sometimes used to react with the oxygen in an organic substance to generate a greater amount of heat than could be generated by a certain other type of catalyst. Often referr ed to as a 'water-burning' catalyst, this kind of catalyst acts as a catalyst to accelerate the oxidation of a given substance, by creating more of a product that would have otherwise been produced by the breaking down of the substance to its constituent elements. For example, ammonia reacts with oxygen to generate acetaldehyde.Hydrogen, oxygen, nitrogen, and other combustible gases react with the oxidizing agent to produce water, carbon dioxide, and a combination of the two. The condensation products of hydrogen and other oxidizing agents are also referred to as carbonyl compound.By the same reasoning, some methods of oxidation that use bismuth oxychloride and phosphoric acid are referred to as the metal oxide reaction. This reaction is also known as the life-cycle method. Sometimes there are additional steps after the metal oxide reaction. For example, ammonia and nitric acid react with carbon dioxide to form carbon monoxide, which is toxic.Acids, bases, and organic and inorganic compounds all react with oxidizing agents to form condensation products, as well as other products, such as aqueous solutions, gaseous solutions, and solid compounds. Sometimes these products are referred to as fuel.When the oxidation reaction occurs, a chemical reaction occurs between the oxygen and the chemicals being attacked. The reaction makes the organic compound more soluble and weakens it. As a result, the polymer will break down and decompose. Other examples of oxidation reactions include the formation of gases, the formation of oxides, and the formation of solids.

How to Find A Level Biology Past Papers

How to Find A Level Biology Past Papers A Level Biology Past Papers And Exam Boards Information ChaptersAn Introduction To A Level BiologyBiology Past Papers Exam Boards Offering A GCSE Biology SpecificationIs My Biology A Level Still Going To Be Relevant In Years To Come?Looking Beyond The Classroom For Revision HelpBiology at A Level is offered by AQA, WJEC, Eduqas and OCR, among others. Below are two of the most popular exam boards for Biology A Level and their grading systems.AQA A Level Biology Past Papers (7401, 7402)At a glance, this linear specification offered by AQA covers a range of core topics such as Biological Molecules, Cells, Genetic Information, Energy Transfers and Gene Expression, the last two being taught at A Level only.The AS Level course is split into two exams, each worth 50% of the final grade and lasting 1 hour 30 minutes. The second year, however, is assessed over three written exams, each taking 2 hours to complete and making up 35%, 35% and 30% of the final mark respectively.OCR A Level Biology Past Papers (H020, H420)This specification leans on th e practicality of Biology for students and integrates problem-solving to help pupils understand biological concepts and scientific methods. Like the above, the course is split between the two years of study, with the first being a valid stand alone qualification.The course is said to refresh the popular themes from GCSE Level specifications and embeds new teaching modules centred around answering the all important question: How does Science work?Is My Biology A Level Still Going To Be Relevant In Years To Come?Not only are there administrative changes for exam boards to consider, like those set out by the government and Department for Education, but naturally they also need to ensure that their courses are always up to date and focus on contemporary scientific research as well as the content that was discovered many years ago.Although the basics will always remain the same, students can look forward to seeing references to new technology and more recent breakthroughs to support thei r learning of key concepts as the A Level syllabi embrace the latest trends in biological research.Thanks to innovative tools, a Biology research is still being conducted and new discoveries found. Photo by longlabcomms on VisualHuntThat said, as with any subject that is still being developed, discovered and experimented with daily, there will of course be some boundaries to your qualification. Clearly, you can only learn as much as the field and syllabus currently allow, so if a huge breakthrough occurs in the next couple of years, or a brand new species of animal is bred, then these  will not be things that you will have covered as part of your high school education.However, Biology as a subject teaches pupils how to problem solve themselves so it is essentially producing biologists who can, in turn, manipulate their existing knowledge and tools to make new, groundbreaking discoveries relating to the Science.With Biology being such a continuously evolving study of life, concepts a nd processes will naturally change as our world, population and species evolve. But that is ok - we expect that in 20 or 30 years' time, your qualification will still be as relevant as it is today because your generation will only see and experience slow and steady changes in the grand scheme of things.Take your  A level biology courses here.Looking Beyond The Classroom For Revision HelpWhy Use Past Papers?Your teacher will no doubt have already told you, but past papers are one of the best forms of revision that you can do.Doing past papers is especially useful to help you to formulate exam-style responses that are suited to your course level. By using past papers properly, you can work on improving your technique and growing in confidence. However, it is no good simply reading past paper questions or just jotting down answers haphazardly.You must train yourself to cope with the pressure of exams so make sure that you put yourself under the same conditions as you would in a real ex am. Below are more tips on how to benefit from past papers in your subject.How To Use Past Papers To Your AdvantageYour teacher may organise a mock exam for you, or set a classroom task which simulates an exam. Either way, the key is to stay focused and to take away the maximum from this very valuable experience.If you are practicing at home using past papers, don't shy away from doing them properly. Ask your family not to disturb you for the duration of the trial exam (if you consult your exam board's website, you can find out exactly how long your exam will be, although this should be clear enough on the paper you have downloaded and printed out too).Be sure to get yourself in the zone beforehand - make sure you have used your revision cards, read through your textbooks and classroom notes, have been to the toilet and only have the essentials with you like a bottle of water and some stationery.Most importantly, make sure you have switched your mobile phone off so that you are not distracted. Also, to avoid any temptation to look at your phone display during the course of the task, don't use it as your stopwatch. Look for a timer or alarm clock around the house or even ask a parent or guardian to come and alert you when your time is up.As you will recall from your GCSE exams, the exam conditions are very strict!Exam-taking is not all about what you know and how well you cope under pressure though. A very important aspect of being assessed is the way you write your responses. Consulting past papers can enhance your ability to respond well and gain extra marks by teaching you what it is the examiner is looking for.Use the documents and resources provided by the exam boards to ensure you are as happy and confident as can be entering the exam. Photo by SGPhotography77 on Visualhunt.comFamiliarise yourself with the types of questions that are commonly set and ask yourself what it is they are trying to get out of you. Furthermore, find out what can add or lose you points in the exam, as mastering this technique could be the difference in you getting one grade or another when the results are published.You can do all of this by checking out a range of valuable resources for revision like past papers, the mark scheme and examiners' notes, all of which can be found on the relevant exam board's website and are usually free to download.For further help, you can search the web for 'biology tutors near me' or 'biology a level tutor'.

Career Management 5 Tips To Help You Avoid Co-Worker Bullying - Introvert Whisperer

Introvert Whisperer / Career Management 5 Tips To Help You Avoid Co-Worker Bullying - Introvert Whisperer Career Management: 5 Tips To Help You Avoid Co-Worker Bullying It’s tough when you’re the new person on the job.  There are a lot of things you don’t know.  You’re learning how things are done, who to go to or the office politics.  You are also dependent on others to help you learn your job.  Although we always hope to be greeted with open arms in the new job, there are times when you become the target for behavior ranging from teasing to downright bullying.  You would think we left that kind of behavior in middle school but when conditions are right, a group of people can do some pretty nasty things to the person that doesn’t “fit in”. When you are the brunt of bad group behavior it’s demoralizing and can be bad enough to make you want to leave your job.  That alternative isn’t a bad one to consider but since it is a big step to take, consider it only after you have tried a few of these things: Single out a few people to connect with personally.  Select a couple of people in the group that you feel you have a better connection with or, at least, the potential.  Look for opportunities to spend a few minutes with these people in a one on one setting and get to know them.  Ask them questions about their work and personal life.  In the process, they will get to know you absent any pressure from their work friends. Sometimes all it takes is building a connection with a couple of people for the rest of the group to decide to accept you. Figure out who the alpha is.  All groups have an informal alpha leader.  They are the “go to” person for their opinions and direction.  Figure out who that person is, what makes them tick and focus on successful interactions with them.  Sometimes, if you win over the alpha the rest of the group is won over as well. Stay focused and upbeat.  Humans do have a tendency to pick on their own if they perceive weakness.  A new employee fits that description because they don’t know much and are dependent on others until they get up to speed. If you stay focused on learning your job and show no signs of backing off, you will be respected simply because of your tenacity.  You have to be more persistent than they are.  It’s hard to keep up that kind of bad behavior when you lose any reason to be a pest. Find a mentor.  You may need to find a person at work that will act as your personal mentor and advisor to help you through this situation.  A mentor who knows the group dynamics and business should be able to advise you on specific things you can do to be successful with the people you work with.  Often times, that person can also be your champion in the group which can go a long way to help. Talk to the boss.  The boss may or may not know the extent of problems the others are causing for you.  If their behavior is affecting your ability to do your job well, you need to be communicating with the boss to work on solutions.  This needs to be done long before your performance puts you in danger of being fired.  When you do go to the boss make sure you aren’t presenting your point in an overly emotional way.  Document the behavior problems and how you see if impacting your work.  The boss can’t fix a problem if they don’t have specifics. This situation isn’t fun and even if you turn it around it may still be so damaging that you want to leave.  It’s understandable that you may still want to get as far away from the situation as possible.  You don’t want to act too hasty.  Most conflict can be improved.  The key to this situation is to keep your head high, act professionally and be persistent.

#TBT to the 90s 5 Easy Guitar Songs for Beginners

#TBT to the 90s 5 Easy Guitar Songs for Beginners Sign up successful 1. Today by The Smashing Pumpkins One of The Smashing Pumpkins’ radio hits from Siamese Dream, this track features a powerful wall of guitars and a catchy chorus. It’s also a great way to get accustomed to two guitar techniques that defined 90s rock: two-string melodies and barre chords. Two-string melodies, like the intro guitar lick, rely on the player holding his or her fingers down over two strings at the same time so that both continue to ring out after they are plucked. In this case, use your index finger to hold down the eleventh fret on both strings. Then, use your middle finger for the thirteenth fret and your ring finger for the fifteenth fret. Intro Riff: Barre chords are based on a movable chord shape, which means you can use the same fingering to play a chord at any fret you want! They also require you to place your index finger down over all strings at the fret you are “barring.” For example, “Today” uses the following chords: Eb Major, Bb Major, Ab Major, C Minor, F Major, G Major Eb Bb Ab Today is the greatest day I’ve ever known Eb Bb Ab Can’t live for tomorrow, tomorrow’s much too long Eb Bb Ab Eb Bb Cm I’ll burn my eyes out before I get out F Ab C F Ab Cm I wanted more than life could ever grant me F Ab C F Ab G Bored by the chore of saving face Eb Bb Ab Today is the greatest day Ive ever known Eb Bb Ab Cant wait for tomorrow, I might not have that long Eb Bb Ab Eb Bb Cm Ill tear my heart out before I get out Eb Bb Eb Ab Eb Bb Eb Ab Today is.. today is.. today is.. the greatest. Eb Bb C Ab Eb Bb Cm Day hee-yay, oo oo ooo ooo ooo. Day hee-yay-ay, hooo Placing your finger down across the entire neck can be tricky at first, but keep practicing, and it will pay off! This technique is very common. If you can’t do it at first (and there’s no shame in doing this!), you can substitute the barre chords for power chords. Power chords are basically just barre chords that omit everything but the first two or three strings, resulting in an “open” sound that goes great with a ton of distortion. 2. Wonderwall by Oasis Everyone’s learned this song at some point â€" it’s practically THE acoustic guitar song of the 90s. Central to the song’s playing technique is its exclusive use of G position chords in the verses. These are chords that revolve around the open G Major chord position. Basically, it means that your last two fingers don’t ever have to leave the third fret. G Major, A7sus4, Dsus4, Em7, Cadd9 This technique sounds really cool, and it makes the song easier to play since you only have to move two fingers! Oasis plays “Wonderwall” with a capo on the third fret, but this isn’t necessary. Play it wherever you think it sounds good! Em7 G Today is gonna be the day Dsus4 A7sus4 That theyre gonna throw it back to you Em7 G By now you shouldve somehow Dsus4 A7sus4 Realized what you gotta do Em7 G I dont believe that anybody Dsus4 A7sus4 Feels the way I do Em7 G Dsus4 A7sus4 About you now C D Em And all the roads we have to walk are winding C D Em And all the lights that lead us there are blinding C D There are many things that I G G/f# Em A7sus4 Would like to say to you but I dont know how Cadd9 Em7 G Because maybe Em7 Cadd9 Em7 G You’re gonna be the one that saves me Cadd9 Em7 G And after all Cadd9 Em7 G A7sus4 You’re my wonderwall 3. Smells Like Teen Spirit by Nirvana No 90s list is complete without mentioning this track â€" it should probably always be number one! “Teen Spirit” is all about power chords. They’re played with heavy distortion during the chorus, punctuated by the simplest possible, two-string melody during the verses. Power chords are notated with a “5” because they consist only of the root note and the note 5 scale degrees above it. Most players play these chords with three fingers: the index, middle, and ring, OR the index, middle, and pinky. Some, however, prefer just the index and ring fingers. F5, Bb5, Ab5, Db5, E5 F5 Bb5 With the lights out, its less dangerous Ab5 Db5 Here we are now, entertain us F5 Bb5 I feel stupid and contagious Ab5 Db5 Here we are now, entertain us F5 Bb5 A mulatto, an albino Ab5 Db5 A mosquito, my libido F5 E5 F5 Ab5 Hey! F5 E5 Db5 Bb5 F5 E5 F5 Ab5 Hey! F5 E5 Db5 Bb5 And the verse guitar melody: It’s actually that simple! Use your index finger to hold down both strings at the same time. Halfway through each verse, Kurt speeds it up into double time, so listen for the rhythm! Another plus â€" the guitar solo in this song is the same as the vocal melody! Try to sound it out as you play along. Getting used to hearing melodies as you play them will help you quickly improve your soloing skills. 4. When I Come Around by Green Day Like Nirvana, Green Day takes inspiration from their punk rock predecessors in the 1980s. This means power chords! “When I Come Around” is a very straightforward song, but it’s still so catchy! Also important when playing this song â€" the verses make use of extensive palm muting. Palm muting is a technique where you use the side of your right hand to slightly muffle your strings while you strum. Try to keep your picking hand as relaxed as possible, so that you can keep the mute on when necessary and then take it off to let the chord ring out. F#5, C#5, D#5, B5,  G#5 F#5 C#5 D#5 B5 I heard you crying loud F#5 C#5 D#5 B5 All the way across town F#5 C#5 D#5 B5 Youve been searching for that someone and its me out on the prowl F#5 C#5 D#5 B5 As you sit around feeling sorry for yourself G#5 B5 No time to search the world around G#5 B5 Cause you know where Ill be found B5 When I come around 5. Santeria by Sublime With equal parts reggae and punk rock, Sublime ruled the SoCal scene in the early 90s. This song is unbelievably fun to play and reasonably simple, too. However, this last technique may take a little while to get the hang of. It’s called the ska upchuck, and it’s what gives a lot of ska (and reggae) music its characteristic guitar sound. After each time the player strums a chord, the picking hand is brought up quickly on an “upswing” to hit the strings once again. This time, however, the strings are muted with your fretting hand, resulting in a “dead, scratchy” sound. Try it with any chord you like! Listen to Santeria to get the hang of the rhythm. This technique works especially well on the highest three strings, so try these chord positions first: E Major, G# Major, C# minor, B Major, A Major E I dont practice santeria G# I aint got no crystal ball C#m I had a million dollars but Id, B Id spend it all E If I could find that Heina G# And that Sancho that shes found C#5 Well Id pop a cap in Sancho and Id B Slap her down A B E Dbm All I really wanna know my baby A B E Dbm All I really wanna say I cant define A B E Dbm Its love that I need A B But my soul will have to wait You did it! You’re now a master of five 90s guitar classics! You also got firsthand experience with some of the techniques that defined a decade of music, including barre chords, two-string melodies, power chords, and the ska upchuck. Keep playing along to these songs, and you’ll quickly notice it becoming second nature!

Throughout your academic career, the only thing that changes about maths problems is their difficulty: the principle of each problem is the same, even when the content itself changes (the same thought process can be used for word problems, or calculus problems).Knowing what defines a maths problem is the first step to solving it! (Source: Pixabay Credit: Geralt)Here's what my handy dictionary has to say about maths problems:A maths problem is a question to solve through scientific meansWe can change this definition a little, though: making it more specific depending on where in your academic career you are:Primary SchoolYou should consider the problem like a puzzle to solve, using the information given in the question. In this stage of your learning, it's important to familiarise yourself with numbers, figures and counting. You first focus on the basics of arithmetic, multiplying, place values, the like. Later on, you'll look at word problems like the one below.Here's an example of a question you might see in school:It's 2PM. John and Tim are going to go for a walk in the forest. What time will they get back if their walk lasts 1 hour and 45 minutes?Secondary School Maths ProblemsDuring the first stages of your secondary education, you'll learn about expressions and fractions. Things are  getting trickier now, but it's still pretty manageable. Here's a problem for which you'd need to find a solution in secondary school:John has 10 sweets. He hands two to Sally, and twice as many to Jane as he gave to Sally. Finally, he gives Fred a third of the number of sweets that Sally and Jane have together. How many sweets is John left with?GCSE Maths Revision / A Level ProblemsHeading into your GCSEs and A levels is where things really start to get tricky, and where having a well-honed problem solving skill set can really come in handy. Every problem you come across at this level will require some thought and problem solving knowhow. They will also mix together topics you have previously studied: algebra and fractions may come up in the same question, for example.Here's an example of such a problem:Nick has 75 metres of fence. He wants to mark out an are a in a field with his fence, and this area must be rectangular. It must also be as large as possible, in order to fit as many sheep in as possible. What's the largest area that Nick can fence off, and how can he calculate this?The level of difficulty in each of the stages of academia differs, but the principle remains the same. We're given a scenario, some clues, and a question to answer.If you don't like thinking about maths, picture yourself as a private detective, given several clues to crack a case wide open!Making the Most of Maths LessonsYour maths teacher won't ever give you a piece of homework, or an exercise, that doesn't match up with something you've done before in class.Fun mathematics class with Einstein. (Source: yesofcorsa)Lessons normally work as follows: you will have a lesson on a particular subject, and then you have to practise by yourself (usually by attempting problems), and work out how much of the content you understand. Then, normally your teacher will set a test at some point on the content.As much as you might find the lessons a little dry at the time, they're the first step in improving your understanding of mathematical concepts, and it's essential you put the effort in and get it right.Before trying to tackle a math problem, make sure you've understood the concepts you were taught during the lesson, because they'll undoubtedly be linked in some way.So, summing up - to make the most of your maths lessons...Listen carefully to your teacher (for the whole lesson!)Test yourself with questions on topics you're uncertain of, so you can get some practise in!Learn off by heart important and simple concepts (for example: Pythagoras' theorem).Start making your own revision folder, detailing all of the concepts covered in class.If you want to go further in your studies, or maybe you're struggling a little in class, you could consider a maths private tutor, who can go through the content with you at home, at your own pace.Reading the Question : Take your TimeFaced with math problems, at home, in an exam, or in class, your first instinct should be to read the question. And then read it again. Maybe even a third time for good measure.Basically, missing one small detail could be the difference between getting the correct answer, and only being able to present witty doodles to the examiner!Fear not, though! Just follow these simple steps, and you'll have the maths cracked in no time:Keep your workspace as tidy and distraction free as possible: make sure everything is organised, and only have the essentials cluttering the desk.Make sure you read the question several times.If you can, draw a diagram or model of the problem.Highlight anything in the question you think will be key to solving it.Try and put into your own words what the question is asking.Follow these steps, and practise with them too, and you'll find yourself doing them out of habit when it comes to exam time.

Having concepts explained to you at your own pace, within the comfort of your own home, works better for some people than sitting in a classroom with 25 other students!To get a feel for this, here's an example question about equations...When Gina was born, her mum was 30 years old, and her brother 4 years old. Today, the ages of Gina, her brother, and her mother, add up to 100 years.If we call Gina's age 'x', express the ages of her brother and mum as a function of 'x'.How old is Gina today?Have a read through of the question a few times, and try and pick out the key information. Once you've done this, here's a breakdown:We know that Gina's mum was 30 years old at Gina's birth.We know that Gina's brother is 4 years older than she is.We know that all of their ages added together is equal to 100 years.So, from these facts, we can fairly easily determine an equation:We call Gina's age 'x'.The age of Gina's brother is 'x + 4'The age of Gina's mother is 'x + 30'Really, we're looking at some fairly basic math problems, just dressed up as a fancy word problem.Learn how to graph functions or discover the list of  unsolved maths equations.What About Harder Maths Problems?Th is example was pretty simple, but it shows you how you can extract information from a worded question and turn it into figures used to solve a problem using concepts you learnt in your math lessons.For a harder problem, you might have to take the clues you've identified and then test a few different theories and see what works.This is when all the practise you put in earlier really counts, and listening to your math teacher pays off. Have a repertoire of mathematical concepts and theories you can call upon to work out how to solve the problem really makes finding the solution easier.If you're still stuck, try thinking back to questions you've done before. Particularly in exams, the questions often follow some sort of format or pattern, and being able to recall a previous question of a similar style might help you solve the one currently in front of you.Checking Your Answers!Make sure to double check your solutions. Perhaps ask a friend? (Source: Pixabay Credit: Leo Valente)Of course , all of the hard work you just put into answering the question is in vain if you didn't get the correct answer - this is why it's so important to check the answer you got! This is especially easy in questions involving equations, which is helpful, as it's quite easy to slip up while factoring.Check through your calculations again, making sure you didn't slip up anywhere and make a small mistake - especially early on, where any mistakes made will cascade into later parts of the question.It's also worth reading the question again, to check you haven't made any assumptions about the question accidentally, or didn't miss any key facts.Finally, remember that not all maths questions simply require you to throw any old number in as the answer. Some (particularly in exams) require you to justify your answer, or add some detail to it in some other way. And yes, this may (gasp)  involve writing a small paragraph. This is especially true with math word problems, where the question was given a s a paragraph.If this is the case, make sure you do fully answer the question, and make sure you write legibly, and that your answer makes sense, and is free of spelling or grammatical errors.Summing UpSo, to sum up, solving maths problems is all about having a sound and simple method for approaching problems, and rigorously practising applying this method. From kindergarten through to college, the same processes can be used to work out the answer to a maths problem. Simply follow logical reasoning and you'll get the solution in the end!If anything above sounded a bit tricky to you, or maybe you just want to gain an extra edge, consider taking up some private maths tuition. Private tutors can work at your pace, and target their teaching approach towards what works for you personally - they can really make a difference when it comes to boosting your grades!

English questions with How and the first Apple computer

English questions with How and the first Apple computer Many questions in English begin with the interrogative word how. How do you use it? Read the story, then see the series of questions below for some examples.The Christies auction computer.Like a lot of people these days, Im a geek for Apple computers. Every computer Ive purchased since 1992 has been an Apple. If I had a cell phone, itd be an iPhone. So I was interested when I found out that later this month Christies will auction Apples first product, the Apple I personal computer, for an estimated $160,000-$240,000.Many consider the Apple I to be the first personal computer. It was also Apples first product offering. Apple cofounder Steve Wozniak built 200 Apple I computers by hand, in Steve Jobs parents garage. They sold for $666.66, which would be $2,500 adjusted for inflation. Although it doesnt look like much by todays standards (see the photos to the right), the Apple I helped to spark the home computer revolution when it was released in July 1976.Christies auction house is sel ling a superb example of the Apple I. They estimate that the price will now be between $160,000-$240,000 after bidding.If you should be lucky enough to win the Christies auction, youll get the Apple I in its original box with the Apple I cassette interface, and a signed letter from Apple cofounder Steve Jobs.The original Apple I had to be mostly assembled by the buyer, except for one important part, the motherboard, which Wozniak put together in the garage.Ok, and now the grammar!The interrogative word how can be used in several different ways:To ask about the quantity of uncountable English nouns:How much did the first Apple I computer cost?The Apple I, after assembly.How much will the Apple I sell for at the auction?How much do you think it is worth?To ask about the quantity of countable English nouns:How many Apple I computers did Steve Wozniak make?How many are left?To ask in what way, or by what manner something was done:How did they build a computer in a garage?How did Apple b ecome such a big company?To ask about the condition or quality of something:Apple started selling computers in 1976. How is the company doing now?How was your trip to the Apple store?To ask about the extent or degree of something:How old is the first Apple computer?How long did it take the company to move out of the garage?As a substitute for why, when used with come:How come Apple got so popular?

Huntington Learning Center is celebrating Mathematics and Statistical Awareness Month in April 2017

Huntington Learning Center is celebrating Mathematics and Statistical Awareness Month in April 2017 Huntington Learning Center is celebrating Mathematics and Statistical Awareness Month in April 2017, an annual event that recognizes the importance of mathematics and its applications and developments in specific areas. Huntington joins schools, educators, colleges, universities, communities and others to celebrate mathematics as an integral part of everyday life. Math is the building block for many essential careers and plays a central role in some of the worlds greatest innovations. In the past year alone, weve seen technological advancements that are changing the way we livefrom smart robots to genetic engineering to artificial intelligenceall of which are examples of math in action. This month, we pay special attention to maths many applications in solving real-world problems large and small. Parents can join their efforts this month and year-round by helping their children recognize maths important uses and put it into practice in their daily lives. Here are some suggestions: Have your child estimate the grocery bill as you shop. Point out careers that require math skills, especially among people your child knows or admires. Plan a family trip, and have your child calculate drive time or mileage between destinations based on speed limits and distance as well as a trip budget that includes the cost of flights, hotels, gas, meals and other expenditures. Invite your child to cook with you and calculate all measurements for recipes. Take your child to the bank every time you go and talk about moneysaving it, earning it and how interest compounds in an interest-bearing account. Take note of the use of statistics in everyday life: in the polls for the recent Presidential election, to deliver accurate weather forecasts, in stock market predictions and more. Talk about maths role in some of the most significant discoveries in history: the landing on Mars and the invention of photography, for example. Mathematics Awareness Month began in 1986 when President Ronald Reagan issued a proclamation to establish National Mathematics Awareness Week. This annual celebration is a collaborative effort of the American Mathematical Society, the American Statistical Association, the Mathematical Association of America and the Society for Industrial Applied Mathematics. In 2017, the name of the holiday was changed to Mathematics and Statistical Awareness Month. To learn more about Mathematics and Statistical Awareness Month, visit www.mathaware.org

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!
