What Is Entropy Chemistry? - Information You Can Use in Your Lab

What Is Entropy Chemistry? - Information You Can Use in Your LabWhat is entropy? How does it relate to your work in the lab? Why is it important? The answer to these questions can help you do your job better.Most of us think of entropy as an important part of the universe, but it is actually more related to the way we work in the lab. The word itself means 'change' and this describes the dynamic nature of the processes we go through in our research. It is the sum total of the changes we are subject to in any given experiment or procedure.The two physical properties of atoms, mass and energy, are also described as something that is changing, just like entropy. The latter describes the accumulation of energy, but because it is always changing, the two are actually one and the same.What is important is that what changes are relative to the total energy of the system. It is also important to note that this is not a static property. If we treat it as such, it would be a very limited defin ition, meaning we could never measure it in a lab setting.The main aim of the material involved in a scientific experiment is to determine the chemical reactions taking place in a given experiment. Depending on the experiments, there are different methods used to perform this task. Depending on the method, the two substances being analyzed are either dissolved in a solution or suspended in the solution. This allows for them to be studied under a microscope, allowing them to be examined at various levels of magnification.The microscope has been used for decades to see the various heights of gas molecules in water, allowing for measurements to be made at various levels of magnification. It is often used to compare what is measured to what is expected to be measured. This is the reason why entropy can be used as a measure of the quality of a study. It is a measurement that can help you determine how well the measurements are being done.The bottom line is that it is important to know th e ways that the measurements are being obtained. This helps you get more out of your work and is sure to make you a better scientist!

Should I Take the ACT or SAT

Should I Take the ACT or SAT Both the College Board and ACT Inc. have revealed redesigns and updates to their exams: the SAT and ACT, respectively. With so many changes to these classic standardized college entrance exams, it might be challenging to decide whether you should take the ACT or SAT (or both!). Gone from the SAT are obscure vocabulary words and science section, and the ACTs optional essay now requires more analytical input and a more comprehensive reading test. However, some key differences between the exams remain, and some students skills will align more closely with those tested on the SAT, while others skills will match better with the ACT. You may be asking yourself, Should I take the ACT or SAT? Choosing to take the ACT or SAT can depend on many factors, such as what types of subjects you excel at and if you are adept to retaining information while reading. Putting your focus on mastering one of the two tests can help maximize your chances of getting a high score. Should you take the ACT or SAT? Read on to find out. Should you take the ACT? Perhaps if you enjoy science. There is no science section on the new SAT. The ACT has a science section, one that is highly focused on your ability to interpret graphs and data. A strong understanding of science is not necessarily required, so long as you are able to do two things: perform basic math analyze tables and figures [RELATED: How to Create an ACT Prep Plan] However, science questions of any typegraph-based or otherwiseare more appealing to some students than others. If you are one of these students, you might prefer the ACT to the SAT. The opposite is also true: if you are easily intimidated by huge amounts of scientific data, you might want to take the SAT instead of the ACT. Should you take the SAT? Perhaps if you like math. The ACT still allows students to use a calculator on all math questions. While the SAT allows a calculator for some math questions, it now also includes fill-in-the-blank questions and other problems that require written work that must be completed without the aid of a calculator. [RELATED: How to Create an SAT Prep Plan] Students who excel in math and can typically perform problems quickly without a calculator might do best taking the SAT. Conversely, students who are not as strong in math compared to other subjects, or students who are intimidated by math problems that dont allow calculator use, might want to opt for the ACT. Should you take the ACT? Perhaps if you excel in reading. Reading questions on the new SAT will almost always provide you with the line numbers in which you can find the information you need to answer them. And even in cases where the line number isnt provided, its relatively easy to find the information you need because the questions progress in order with the passages youve read. On the ACT, however, reading questions are ordered randomly and usually do not provide line numbers with relevant details. So, it can be challenging to find details in the passage that correspond with the question. If you excel at naturally retaining information as you read, you may do quite well on the ACT. If you have trouble with remembering the information you read or going back into written passages to find details, youll probably prefer taking the SAT. Should you take the ACT or SAT? Consider the colleges to which youre applying. Dont forget this important piece! If youre a high school student thinking about these exams, youre probably thinking about the college application process as well. Go through your short list of schools and do a little research. Which ones accept only the ACT or only the SAT as part of the admissions process? Do any of them accept both tests? Make sure you understand the admissions requirements of your prospective colleges before making any big decisions about the ACT or SAT. The answer could be right in front of you when browsing a colleges website! With their latest rounds of changes, the SAT and ACT have a lot of new material to consider. However, key content differences between the exams remain, and some students may prefer one to the other. By identifying your strengths and weaknesses and understanding what your prospective colleges require, you can choose to focus on studying for the test thats most closely aligned with your skills and goals.

The Best Tips For Buying Maths Equipment

The Best Tips For Buying Maths Equipment Maths: How To Choose Your Basic Equipment? ChaptersWhat Is The Essential Maths Equipment Needed For The Maths ClassroomMaths Equipment For SchoolThe back to a school shopping list is a long one, especially with the ever-growing number of subjects in the education program. This curriculum development has meant that now not only do you have to provide the basic school supply list for students. But you also have to add to this special equipment for classes like arts crafts (art supplies like a sketchbook, coloured pencils, paints, an easel and crayons) or get costumes for a role play or active play in the school theatre.The school math curriculum alone requires a large number of back to school supplies. School shopping for a mathematics course alone can include a scientific calculator (depending on the grade level for lower grade a basic calculator is fine), textbooks, post it, paper clips, a binder, rulers, markers, highlighters, sharpeners, an eraser not to mention the basics like pens and pencils. This excludes any real moder n conveniences and high ticket items.Despite how long the school supplies list happens to be. It is the parent's job to guide their children and provide them with all of the tools which create the opportunity to perform at their best. It is the child's job to take that opportunity and those tools and turn them into success. Student achievement provides a flash opening to better privileges, university placements, higher paid jobs and happier life overall. Knowing you have done your best and had the opportunity to demonstrate that it is a rewarding feeling that is hard to beat.So while the ever-growing school supply list could be fast multiplying into school supply lists. Lack of study/office supplies should not stand in the way of Student learning, and it should not be the thing to disrupt the learning environment. For example to try to find or borrow equipment in the middle of classroom activities.For students, mathematics courses can be a challenge, times tables, counting, dividing , multiplying, calculus, fractions, algebra, addition and subtraction are just the tips of the iceberg when it comes to maths courses and student development.Looking at high school math, let's consider which equipment is needed to excel on the course.

The good thing is that if you ask your math teacher, they will be able to give you either a math worksheet with the lesson plans for the coming year so that you can research the equipment required. Or if they are more organised, they will provide you with a math class supply list.You don’t have to wait to ask for this list, as a core subject, the math curriculum doesn’t change much. So teachers will be able to advise you on what will be useful for your entire high school or college attendance. However, if you prefer to go year by year, you can ask teachers at school open evenings, parents meetings, write notes to the teacher or arrange an end of year meeting with the teachers you would like to talk to.If you have missed the opportunity to speak to the educators at school or don’t have the time for that, however, then the below list will be very useful to get you started.Discover a maths tutor that can help you through le arning maths here.The back to a school shopping list is a long one. Photo Source: UnsplashMaths Equipment For SchoolCalculatorIt may surprise you to find out that there are many types of calculators in the market. Each different kind of calculator is meant for a different job. The simple calculator in kindergarten may be the same as the one used in primary school, but it most certainly will change when you get to high school, college and university.While you can do the more complex calculations on a basic calculator, it really serves you well to invest in a calculator that will meet your needs. The whole point of a calculator, after all, is to help you with mathematics.Simple Calculator - This is the Primary school level calculator which specialises in subtraction, addition, multiplication and division.Scientific Calculator â€" The scientific calculator can do everything that the simple calculator can do. It is also able to perform much more complex equations and calculations. You c an perform calculations like Pre-Algebra,  Algebra, Precalculus,  Calculus, Geometric, Fractions, Equations, Algebraic, Competency, Trigonometry, exponents and logarithms. This is a high school to university level calculator. This is the most useful calculator and the one that makes the best investment for a math studentGraphing Calculator - The Graphing calculator can do everything that the simple calculator (like Pre-Algebra and Precalculus) and the scientific calculator can do (like Geometry,  Trigonometry and algebraic calculations). It also has the added function of being able to perform calculations of integral calculus and matrices. And when you type something in to be calculated you will see a graph of it in the graphing calculator screen. This is a calculator for college and university level students.guide their children and provide them with all of the tools which create the opportunity to perform at their best. Photo Source: UnsplashGeometric Measuring  ToolsGeometry is a type of maths that works out the areas and diameters of 2-D shapes and figures as well as points, lines and angles.The four important tools of geometryRuler - A ruler is a tool that we all know and love because despite its simplicity we can not live without it if we want to draw straight lines. It also is used to measure distances. One with 12 inches and 30 cm will be fine for any math class no matter what grade level the student is in.Compass - This a tool used to draw circles or arcs of circles. It is a metal tool set in a v shape that has a point on one tip and a hole to hold a pencil on the other.Protractor â€" Not too dissimilar to the ruler except this is set in a semi-circular shape with measurements of angles from 0 to 180 degrees.  When you lay, the protector on the angle that you want to measure you will be able to easily work out the degrees.PaperWhether for maths or other classes, while you are studying, you are going to need some paper. In maths, you will use this for class notes, calculations and general study.Rough Note Paper - This paper can be from recycled paper found on paper bags, draft paper, receipts, the back off printed throwaways, or you can buy it. The Post it is a fancy version of this kind of paper.Graph Paper â€" This paper as it sounds is made up of lines that cross to create small squares it is often used in maths as it makes it easier to write out equations, draw graphs and design charts.CarriersNow that you have all of your maths kits don’t forget to buy something to carry it in.A pencil case â€" The pencil case allows you to carry everything you need and doesn’t take up too much space on your desk. A great way to organise your kit since you will have lots of different classes. Is to have a general pencil case with your basic stationery in it, then have class specific pencil cases that have the tools for your specific courses.backpacks â€" The backpack is another great tool for organising yourself for school. Buy one that has enough space for all of your books and other stuff. Buy a smaller bag for your gym kit if you have gym classes. As dirty trainers will tear and mess up homework and coursework in your main rucksack. It is advisable to have separate bags. If you do swimming or art too. As wet paint and a damp swimming costume will ruin anything in your backpack.Essential Maths Equipment Needed For The Maths Classroom. Photo Source: UnsplashOther Basic stationeryPens â€" gel pens are my favourite as they give a smooth writing experience. They also have a padded finger area. But pens are a personal choice.Pencils â€" this is very important as it is better to use pencils over pens in math as you will likely need to erase things lot as you update your work.Eraser â€" as mentioned above they need to keep work up to date and correct pencil mark mistakes. (liquid erasers like tipex are also useful for mistakes made with pens.)Highlighters / coloured pencils â€" help to highlight your work and create eas y to read sections. You can also use different coloured pens for this reason.Notebook, planner â€" Notebooks are essential for taking notes in class and for your own thoughts on the course and the work. Planners, however, are great for planning out your workload, homework, and your time table.Being a student is hard work, even the math equipment you have to invest in is a long list. However, the reality is that while the tools are useful, it is really you that brings success to your student life. However, you approach this part of your life to remember that learning is a lifelong journey.If you are looking for back to school kit ideas for young kids, check out the math supplies for kids blog!

To Learn More Keep Testing Yourself

To Learn More Keep Testing Yourself It turns out that taking a test isnt just a teachers easy way of finding out where students stand or forcing them to read a chapter in a textbook. Testing might actually boost student learning and improve memory retention, according to a report cited in the New York Times. The report, published in the journal Science, concluded that students who read a passage and were then tested a week later on what they read retained about 50% more of the information than students who used other, common study methods. The other methods students used were repeatedly studying the material cramming and creating detailed diagrams of the information, connecting it all together in students own words and thoughts. Many teachers believe that the latter method is an effective method for studying because it forces students to create connections among information points. These two methods can give students the false belief that they know the information better than they actually do, according to the report. The results surprised many cognitive psychologists and other educational scientists who long believed that creating connections among information was the best method of learning. For the test, researchers placed 200 college students in two experiments, both experiments had them read several passages about scientific subjects, like the digestive system or muscle tissues. In the first experiment, students were separated into four groups. The first simply read the passage in a five-minute session, the second read it in four separate, five-minute intervals, the third engaged in concept mapping, creating hand-drawn diagrams and bubbles to link the information they read in their own, personally-organized fashion, the fourth group took a retrieval practice test, where they free wrote every thing they remembered for 10 minutes. This group then reread the passage and took a second retrieval practice test. All four groups were than given a short-answer test a week later, assessing how much of the information they could recall and the logical conclusions they could create about what they had read. The students in the fourth group, who performed the retrieval practice tests, outperformed all other groups. The second experiment focused only on concept mapping and retrieval practice testing. Students were separated into two groups. One group created a concept map, and the other group took tests, asking them to recall information. Similar to the first experiments results, the students who took retrieval tests recalled more information a week later, even when they were asked to draw a concept map from memory. Cognitive psychologists cannot exactly pinpoint what causes these results. But, many believe its because taking preliminary tests gives our brains practice. Our brains can create contextual cues and patterns for remembering information during the preliminary tests, making recall easier because the brain can then remember the cues and the patterns, which can then lead to remembering the information itself. Then once the second test is administered, our brains can easily recall these patterns or context cues because they were previously in our minds. These results have practical applications as many teachers administer quizzes or practice tests before larger, more-weighted exams, or even when teachers administer mid-term exams then final exams. Students who were previously tested on material will be able to remember it more effectively when they are tested again.

4 Questions to Ask Your Child About School

4 Questions to Ask Your Child About School Through report cards, parent-teacher conferences, and grades posted online, tracking your childs educational progress is often relatively easy to do. Aside from these mediums, though, one of the best ways parents can assess progress is by having regular conversations with their student. This will help you not only gauge how theyre doing, but also teach them to reflect meaningfully on what theyre working on in school. Questions to ask your child about school include what they find interesting, areas where they encounter confusion, and their favorite activities. Looking to help your student finish the school year on a good note? Keep reading to learn four questions to ask your child about school. Question #1 to ask your child about school: What do you know, what do you want to know, and what have you learned? KWLwhich stands for know, want to know, and learnedis a series of questions that may already be familiar to your child, as some teachers begin units by filling out KWL charts as a class. This technique works at home too, and is best for gauging progress on a specific subject, unit, or concept. Have your child list things that they know about a concept, as well as what they want to know. This is especially helpful to do during a unit to see how theyre progressing through the quarter or semester. At the end of the unit or course, ask them what theyve learned. Is there anything theyve been exposed to, but still dont quite understand? Have they learned everything they wanted to know? A mismatch between the want to know and learned columns could signify one of two things: Theres something that you and your child should focus on and make sure to clarify as the class moves on. Theres an interest of your childs beyond what the course is designed to teach. This could be a place to explore and expand in terms of your childs academic or personal interests. [RELATED: How Parents Can Help Students Setand AchieveAcademic Goals] Question #2 to ask your child about school: What do you find interesting about [a specific subject]? KWL charts can be a wonderful tool, but sometimes students say theyve learned nothing at school when asked. One way to better focus your conversation is to ask about whats interesting about a subject or class instead. When your child talks about the subject, notice the way they speak about it and if they seem to have a strong grasp of the subject. This information can help clue you in on how confident your child feels in the given subject, and whether or not that confidence matches their comprehension of the material. [RELATED: 3 Questions to Ask Your Students Teacher Before The School Year Ends] Question #3 to ask your child about school: What do you find confusing about [a specific subject]? Similarly, asking whats confusing about a subject can help you learn more about how your child experiences school or a specific class. This may be difficult for your child to even put into words, but its a worthwhile endeavor and will often shed light on whats happening in class. Some follow-up questions can include: What do you do when youre confused in class? Does your teacher notice or know when youre confused about something? What does the teacher do when you or your classmates are confused? This might be a great time to offer some in-class or at-home strategies for your child to use when they get stuck. Consider their personality; when a student is shy or simply nervous to express their confusion in front of the whole class, suggest that your child write a note to the teacher or ask to speak to the teacher while other students are working on an assignment. Question #4 to ask your child about school: What are your favorite and least favorite activities? Finally, assessing your students educational progress can include getting a sense of class activitiesincluding what they enjoy and dont enjoy, as well as what activities are most or least helpful. This can help you understand the ways in which your child participates in class, works with other students, and how they best learn material. [RELATED: How to Support Your Stressed Student] The answers to any of these questions about school are great for you to help your child make a plan for how to best use homework time, in addition to coming up with strategies and things to do in class that will help them make the most of class time if theyre confused. This information would also be good to bring up in a conference with a teacher or guidance counselor. Remember that your childs teacher is on the same team as you to help your child succeed, and sharing information can help to best accomplish this. Any topics you want to know more about? Let us know!

Perfecting the GRE Quantitative Become an Exponents Expert

Perfecting the GRE Quantitative Become an Exponents Expert GRE/MAT Graduate School Blog Like the thousands of other humanities people getting ready to take the GRE, you may not have thought about exponents since high school. You probably spent your undergraduate years thinking a lot more about existentialism than exponents, and now need to feel confident enough about that tiny superscript number to work with it over and over again on the GRE. The good news is that, like with so much high school math you find yourself needing to review for this graduate school entrance exam, there are a lot of great resources online for review and practice. This article will quickly explain the ways you may see exponents appear on the test, the basics you will need to learn, and good places to look for practice. Exponents Are All Over The Quantitative Section of the Exam If you have already taken one of the free GRE practice tests offered by ETS, you are likely familiar with the fact that every subsection includes questions about exponents. You will see some situations where you simply have to calculate an exponential number and some where you have to solve an algebraic equation. The good news is that once you review and know your exponent rules inside out, none of these questions will be particularly difficult. These are the major concepts involving exponents that you will see on the test: Combining like terms, such as in the expression 3x2 + 4x â€" 7x2 â€" 1 Calculating the value of an exponential number such as 1251/2 43 Simplifying a multivariable expression like (x4y2z)7 / x2y3 Factoring a quadratic expression such as x2 â€" 64 What Should I Review? First things first, know the exponent rules like the back of your hand. These include: Multiplying two exponential numbers with the same base, such as a6 a11 Dividing two exponential numbers with the same base, such as a11 / a6 Applying a second exponent to an exponential number, such as (a2)10 Simplifying a number with a fraction in the exponent, such as 161/3 Simplifying a number with 0 in the exponent, such as a0 If any of those rules look at all unfamiliar to you, or if you don’t know how to complete those operations by instinct, review and student your exponent rules using this great worksheet on Math-Aids.com. You should also go ahead and review factoring quadratics if that’s not familiar to you. Purple Math has a great post on the topic. How Should I Practice? First, learn these concepts inside and out. There are two main sources for quality practice. The first is Math-Aids.com, which has tons of practice problems for exponents and radicals. That site automatically generates worksheets of drills that you can use to practice not just your exponent rules, but any math fundamental that you feel could use some more attention. The free OpenStax textbooks provided by Rice University are also a trove of practice problems. They are, admittedly, a little annoying to navigate, but they are full of quality practice problems. Of course, these are ‘real deal’ text books, so they also include the actual lessons about math concepts. This makes the OpenStax books fantastic review resources. Also, visit MathBlog.com for helpful articles on tons of mathematical concepts. Next, practice some GRE questions. The best way to learn how to apply exponents to the GRE is to actually do it! ETS’s PowerPrep software includes a total of three practice tests, and this will give you a great sense of what you need to strengthen when it comes to your skills with exponent rules. If you want extra GRE problems, just go to your local library or book store and leaf through some GRE prep books to choose the one that has the most practice problems. Additionally, consider working with a tutor. A quality tutor will not just teach the concepts you need to relearn, but focus on the specific points you’re struggling with and make you plenty confident about the math for test day. That tutor will also have plenty of wisdom about the Quantitative section, and can offer you test-taking strategies to reduce the amount of calculation and brain work you need to succeed on the GRE.
