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. If you or your child needs help with Biology  or  you fancy private tuition  then please  view Frank’s personal profile on the Tutorfair website to  book a lesson.

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?

Teaching High School Students To Understand The Concept Of Color Photographs And How To Use Them In The Classroom

Teaching High School Students To Understand The Concept Of Color Photographs And How To Use Them In The ClassroomTeaching high school students to understand the concept of color photographs and how to use them in the classroom can be extremely time consuming. There are tons of illustrations, diagrams, and pictures, many of which are terribly outdated and confusing. There are also often times diagrams and pictures that teachers find difficult to understand.A good teacher is an excellent teacher for a particular subject, because he or she not only knows the material inside and out, but also has developed his or her teaching style in response to the needs of the particular subject. When I was in college, I spent many months studying mathematics, statistics, and algebra, and yet I wasn't entirely sure what I was doing. If you don't have the support of a great teacher to guide you through your study sessions, you are more likely to become frustrated with your work, and to possibly give up . However, as you begin to learn how to identify and manage your own tutoring pictures, you will find yourself moving faster through your lessons, completing assignments, and getting better grades.When you first begin to notice pictures, diagrams, and illustrations with illustrations, your first instinct is probably to identify the person who made the pictures. As a matter of fact, many teachers will throw a blank sheet of paper at their students and ask them to figure out who drew what in the picture. Obviously, you will want to identify who draws the picture for you because you will eventually be given some very detailed answers. Here are some simple tips on how to recognize your tutoring pictures. Let's begin.One of the easiest ways to recognize your own picture is to look at it as if you were going to print it out. If there is a large object on the page, look for any sign of a third person that could possibly be a person but isn't the real person. For example, if you see a pictu re of a mountain in a picture, look to see if there is a view of the 'leaving' hand of the mountain, or any evidence that the mountains' shadow reaches up toward the sun, as you would see on a poster of the mountain.Another tip that works for children in both elementary and secondary schools is to look at the pictures before looking at the text in the journal or other visual materials used by the school for teaching. A teacher might have a certain visual image or picture that she would like to show during a particular lesson. If you see the same image on the page, look to see if there is a caption that explains what it is all about.Another trick is to make a note of the paper label that comes with your picture and look for a description. A paper label is sometimes a stamp that your picture was placed on, so if there is one, look for a description of it. If there are not a paper label and no description, look to see if the image is in the proper orientation. It is important to recogn ize your own pictures because if you recognize your own picture, then you can connect the picture to what you are reading.There are many different teachers who use different methods for teaching. Some will draw their pictures using blue pencils, and others use something much simpler. Some teachers will use their own images, while others will look at examples of pictures drawn by other teachers, and some will even look at pictures drawn by their own students. The question is, which teacher is the most effective for your particular subject?

How Can A Student Access A Personal Tutor?

How Can A Student Access A Personal Tutor?The term 'personal tutor' has come to be used to describe anyone who works with the student and can offer that student help in completing courses. The individual could be a single individual, a group of students, or the school itself. A personal tutor is a person who can offer help with many different aspects of the life of a student such as life skills, academic work, tutoring to choose a career, guidance in parenting, a way to make changes in home life, help with child discipline, and many more. These tutors also ensure that the student retains the ability to succeed at school.When people think of helping students, their first thoughts are usually their own personal development. People do not associate helping students to improve themselves or spending time with them in their personal development. However, when a student is struggling in school and can not continue to meet the demands of the school's curriculum, it can be very difficult for the tutor to help the student because the tutor is aware of the inadequacies and can spot them.Some teachers have found that the most effective way to help a student is to have a tutor to teach the student in their school curriculum. This is because the student will get the opportunity to learn things that they would not otherwise learn, and this helps in their understanding of the curriculum. Sometimes there are things in the curriculum that cannot be taught to the student, for example, mathematics which needs to be taught to them in order to do well in the curriculum. This is why having a tutor in the classroom can help.Teachers also need to have a teacher and mentor that have specialised knowledge about the curriculum that the students are struggling with. Teachers can contact a private tutor to teach the students what they are struggling with, or they can offer the student this to help them, though it can be hard to find a teacher who is committed to helping out a student. Some times it is worth paying to hire a tutor, but there are many tutors that offer to help students out for free if they so wish.When a student has a tutor, they should be able to come to the student to talk about how they are doing and ask for help. They will be able to tell the tutor how they are doing in certain areas and it will allow the tutor to work harder on those areas to improve. However, if the tutor feels that the student is not showing any improvement then they should not assume that the student is not trying hard enough, they should think about whether the student is doing what they should be doing in order to learn. If the student is not doing the right things then the student will not be able to excel in the subject.Sometimes the student may not be confident in themselves and do not want to take on the teacher as their own coach. If this is the case then they should contact a professional coach who will work with the student to give them a good coach. If a student is hav ing difficulties at school, then the teacher should contact a tutor in order to find out why. Then the teacher can consider hiring a private tutor to work with the student and to find a course that can best help the student.In most cases, if a tutor is offered by the teacher, the teacher will be the one to contact the tutor, as most teachers want the assistance of a professional. There are times however, when the student cannot afford to pay a tutor to help them out. In these cases, there are many online tutoring resources where students can access free tutoring help from people in their communities.
