Organic Chemistry Tutor - Build Your Own Lewis Structures

Organic Chemistry Tutor - Build Your Own Lewis StructuresWhat is Lewis Structures? Lewis Structures, also known as Langstonian systems, is a system of polygons or binary modules that can be imagined as little cylinders. These are easy to shape, and they are very flexible as well.Lewis Structures is a system of polygons which were invented by John Langston in the 18th century. The alphabet, which he designed for the systems is known as Langstonian alphabet. He divided the universe into various quadrants, and each quadrant is divided into cells which contain an enclosed field, which creates the regular hexagonal shape.In order to construct new substances from old ones, the subjects made use of Lewis Structure. There are many methods which are used in constructing new substances such as experiment, chemical reaction, etc. When new substances are found, we will have to combine these new substances with the old ones.Lewis Structures is such a system which can easily combine two substances together. Moreover, Lewis systems are also considered to be very accurate. When we try to mix substances, we can always use only three atoms of two substances. This is because the atoms in the molecules do not collide.There are several ways in which we can make the molecules in these systems. It can be by using combinations of different forms of atoms. Furthermore, some of the molecule components can be made in different directions.When you are interested in building a chemical system, you need to learn about the Lewis systems first. You can buy books about these systems. For this purpose, you can go online. There are many websites online that provide the information about these systems.If you wish to build your own Lewis Structures, you can download free downloadable materials from the Internet. You can choose the file format that you like to read. In addition, you can modify the file in any way that you want to.

The Queen of Code - English Listening Exercise

The Queen of Code - English Listening Exercise Im actually a little embarrassed that I didnt know who Grace Hopper was a week ago. She is perhaps  one of the most important people in the history of computers as we know them, but shes not nearly as well known as Steve Jobs or Bill Gates.These days, technology, and especially coding,  seems to be a mans world, with one prominent programmer going so far as to (ridiculously) suggest that men are better evolved to be programmers. The story of Grace Hopper shows us how involved women have been in technology.Interested in Grace? Watch the video below, then see if you can answer the listening questions. The questions are from the first 3 minutes of the video, but if you have time try to watch the whole thing, its worth it.1. What does she compare women in computer science to? Why?2. Grace Hopper is ___ __ one of the most _____ characters in computer science.3. She was _____ long before that was an accepted expression.4. In Cedar Falls, Iowa, they celebrate by ____ ___ for nearby farms.5. What were the women in the above sentence doing?6. Theyd ____ the problem ____, and then two our three days later youd come back and youd have the problem solved.7. Why did she have problems joining the Navy?8. What did commander Aiken say when she went to her first job with the Navy?9.  Id always loved a good ____, and Im afraid that ____ ___ ____ when I first saw Mark I, my first thought was, gee thats the prettiest ____ I ever __.10. Why do you think the audience laughs at the statement above? She uses a word that would be considered a mistake in written English, which one is it?

GCSE Biology What are Genes

GCSE Biology What are Genes As part of National Science Engineering Week, one of  Tutorfair’s top Biology tutors, Frank I, explains how to get to grips with the GCSE Biology topic: genetic engineering. As Frank has a PhD in this specialism and has previously worked in the lab for Cancer Research, he certainly knows his stuff! His first blog post in this series on genetic engineering explains what genes actually are; not your standard Levi’s! Genetic engineering. Thanks to decades of film and TV, it’s a term that conjures images of extreme deformity like Godzilla and Spiderman. Though the reality isn’t quite as crazy, the current and future impact of genetic engineering on each of us and and especially our children is, and will be, HUGEâ€"Godzilla huge. As a species, human beings have been practising genetic engineering for thousands of years, though for most of that time we didn’t know it. From the moment the first tribe of hunter-gatherers settled down and realized that breeding the best wheat plants or the best cows together gave them even better wheat and better cows, human study into genetic engineering began. Today, we don’t just breed our crops and animals to get what we want, we pick genes from one species and pop them into anotherâ€"the ‘Frankenstein’ experiments we’ve all heard about. Let’s back up. Before we can explain what genetic engineering is, I suppose we should get clear on just what a gene is. Genes, DNA, chromosomes, the nucleusâ€"we lump them all together in our heads and that’s fine, because they are just different ways of looking at the same thing.  Chromosomes are just separate chunks of DNA, living in a bag inside the cell, called the nucleus.  If we read along each chromosome, we can divide it up into segments called genes, and there are thousands of them in each and every cell! So what is this DNA stuff that makes up our genes? Well, if you asked someone off the street they would probably say that DNA controls the cell and is responsible for our physical characteristics like eye colour or height.  And they’d be right!  But how exactly does DNA do this?  DNA holds the instructions for what a cell should be doing. For example: the cells of a baby growing in a pregnant mother are instructed to divide rapidly; a muscle cell is instructed to contract; and a nerve cell is told to send an electrical impulse to the brain. Think of DNA as the boss of a busy factory (the cell) sitting high in an office shouting orders down to thousands of workers busy building and assembling a car.  DNA doesn’t actually do any of the workâ€"the workers do!  And each worker is different from all the other workers.  Each worker is specialized to build one and only one part of the whole car, but each does its job very well.  In our cell, those workers are proteins. Proteins come in many different shapes and sizes: long and thin, spherical, ball-and-chain, and loads more.  Like snowflakes, no two are identical.  No two protein shapes are alike and no two jobs for our workers to do are alike.  And each of us can make about 30,000 different shapes, each with a different job!  Like our workers in the car factory where one is great at making the transmission while another is fantastic at making the steering wheelâ€"one protein (insulin) helps us control our blood sugar while another uses a blast of energy to spring forward and contract our muscles.  Different cells like brain cells or heart cells use a different mix of protein workers to do their jobs. Not only does the lazy DNA not do any of the actual work, DNA doesn’t even MAKE the workers.  Little protein-making machines far, far from the nucleus do that job.  DNA simply holds the information for HOW to make the proteins. So how does this all actually work?  Well, I’m all typed out.  Shall we meet back here later for part 2? If you have found this blog post helpful, you might also find Frank’s previous blog post explaining photosynthesis useful.

5 Questions Students Have About Tuition Insurance

5 Questions Students Have About Tuition Insurance pixabay.com 1. What is tuition insurance? Tuition insurance isn’t a particularly common thing for most college students. In fact, it usually benefits the parents more so than it benefits students. In a nutshell, tuition insurance will reimburse tuition costs (or partial tuition costs) should the student drop out of school. Usually the students getting tuition insurance are ones with pre-existing medical conditions that could force withdrawal from school. Because many schools don’t have regulated reimbursement policies in the case of student injury or death, tuition insurance alleviates the stress involved in paying hefty amounts for higher education. 2. Who usually gets tuition insurance? As stated, most of the students who get their tuition insured have pre-existing medical conditions or a medical history that could force a withdrawal from their school. Typically, the parents who choose tuition insurance are paying a private institution with large fees. It’s usually assumed that the paying of such fees comes directly from the parents. With the parents paying such a large cost for their child to attend school, potential withdrawal from that school could result in a lot of money lost. This happens because many federal student loans allow discharge of student debt if one becomes disabled or dies. However, private student loans do not have the same rules and do not have such discharges of debt. 3. How much does it usually cost? Tuition insurance varies based on the amount of tuition paid. Essentially, tuition insurance usually works as a percentage of tuition costs. Tuition refund insurance can cost anywhere from 1 percent to 5 percent of total tuition costs. Depending on the overall amount, this means that the insurance could cost anywhere between $100 to $1,000. Because the range is quite large, it would be wise to consult with a tuition insurance provider to calculate the estimated cost of tuition insurance based on your fees. Keep in mind that tuition insurance refunds will look different depending on various things like credit hours, risk involvement, and coverage. 4. What does it cover? Most tuition insurance will cover things like forced withdrawal due to illness or injury, the death of a student, or the death of a parent. Different types of tuition insurance may also cover things like voluntary withdrawal, mental health withdrawal, relocation, or academic suspension. However, there are exceptions to this rule to which the insurance won’t apply. Some of these cases may be intentional self-injury or withdrawals due to substance abuse. Be sure to talk with your provider about full coverage versus partial coverage. The amounts refunded will likely vary based on the potential events and how much the school refunds. Because the school will likely refund a certain amount should any incidents occur, the tuition insurance percentages may look different than initially proposed. 5. Do I need it? Many students have never heard of tuition insurance simply because it isn’t a common or necessary thing. Because most 17-21 year olds are generally healthy and haven’t acquired major illnesses or diseases, they have little to fear about forced withdrawal from school. Many students also attend large public universities and receive fair amounts of aid in terms of grants, scholarships, and loans. It isn’t particularly common for parents to pay extreme amounts of tuition fees each year. If you’re planning for your future college career and tuition insurance hasn’t come up, the likelihood that you need it is quite low. Now that you have a taste of what tuition insurance is, you can more aptly decide whether you need it or not. However, deciding to get tuition insurance should be a discussion for everyone involved in the college process. It’s best to speak to a real tuition insurance provider about what rates will be charged and what the insurance covers. Make sure you talk explicitly about your concerns and what you want your insurance to cover to find the best tuition insurance plan for you. Much like your investment into your education itself, tuition insurance is something that should be thought about thoroughly. When studying, you don’t want your time or your money to go to waste.

Can practical topics be taught at home

Can practical topics be taught at home Science can be a tricky subject to teach, combining a strong theoretical background with an often exciting and diverse practical element. In a home tuition situation, this practical aspect can be hard to achieve because chemicals, biological materials and safety equipment are difficult to source and dangerous to use. Does this make any difference to an education? The whole purpose of study in general, and the study of science in particular, is to understand the world around us. This does not necessarily entail experiencing it. Some parts of science can not be experienced - for example; we know and understand that earthquakes are caused by tectonic shifts - but we can't witness those shifts ourselves. It should also be noted that final exams for all scientific subjects are heavily biased towards theory. On the other hand, a practical demonstration can undoubtedly aid learning and the retention of information, especially for those students who struggle with the abstract. It is also a way of engendering enthusiasm for the subject. Most adults can recall at least one dramatic science lesson from their childhood. For those areas we can't experience first-hand there are study aids, animations and other visual representations that can help plug the gap between knowledge and experience. As a Science tutor, do you feel a practical element is necessary to this area of education? If so how have you incorporated this aspect in your lessons?
