Definition of Filtration in Chemistry

Definition of Filtration in ChemistryOne of the key skills that a student will need to have as a chemistry major is the ability to define filtration in chemistry. The ability to define what filtration means is extremely important in the life of any chemist. The term 'filtering' is used by chemists to describe the process by which molecules and other solids are passed through a filter or separator.If you study the basic term itself, then you will be able to gain a very good understanding of what the word means. Filters are used to separate different types of materials in order to prevent impurities from getting into the product that it is used in. It is this first definition that people often use when referring to filtering in chemistry. A little further investigation will also reveal that it is very important to know what the exact term means before using it as an example of filtration in chemistry.A filtration system is one that allows for a clear separation of materials. Filters al low for a uniform distribution of substances are separated from each other by size, shape, and density. The most commonly used filtration systems are filters for water, and such as the paper towel. They allow for the removal of impurities such as bacteria and parasites.Filtering in chemistry can be further subdivided into the following: passivation, blockage, and physical. Most people think of filtration in chemistry when they are taught the term 'filtering'. What they may not realize is that there are many other types of filtration methods that are used in chemical analysis.Filtering in chemistry involves the three processes listed above. The first method is the application of liquid or solids through an opening to be separated by mechanical or physical means. Blockage involves using a solute (a solid, liquid, or gas) so that it cannot pass through the filter.The second process is called biological process or biological filtering. This method uses the biological process in which it involves chemicals that a living organism has been exposed to. In the early 1900's, it was discovered that certain liquids were bad for an organism and some changes were made to these liquids to discourage the harmful effects that they had on an organism.The third analytical process is a mass spectrometer. A mass spectrometer utilizes a sample of substance to view the amount of chemical components within the sample. It is used to determine if certain compounds are present in a sample of substance and if so, how big or small the compounds are.

Accused of Being a Suck-Up Thank Them! - Introvert Whisperer

Introvert Whisperer / Accused of Being a Suck-Up Thank Them! - Introvert Whisperer Accused of Being a Suck-Up? Thank Them! I recently spoke at a conference on Office Politics and one of the actions I suggested was forming relationships with your boss and upper management.   (Hmm, relationships â€" sound familiar?)   I was asked this question: Ive been told Im a suck up because I have relationships with management.   What should I do about that? My response:   Tell that person: Thank you for noticing. I want to tell you a few things about why I answered this way. -Forming relationships with your boss and management is a huge part of Managing Up no matter what type of boss you have.   It is never wrong or bad. -People that call you names are acting like a 10-year-old on the playground.   As we know bullies usually dont feel good about themselves.   You backing off on your relationships wont cure their insecurity. -If you’re the one doing the name-calling you need to be ashamed of yourself and work on a new perspective.   The boss isn’t an enemy even if they are a jerk.   Managing up will improve your ability to work well with the boss and if you have a Bad Boss, it will go a long way to soften their dysfunction. -The only thing for you to check on as you support your relationship with your boss is to ensure you arent being a sycophant.   No one, including the boss, likes a person who is being over the top, slathering on complements or compromising your values simply to have a relationship with management. -You can teach others and especially a person who would make a comment like this about why its important.   Maybe point them to my new book: Accelerating Your Career â€" Even with a Bad Boss, a New Approach to Managing Up. You could also suggest they work on their self-esteem or confidence. -If you do have the disgusting type of suck-up in your midst, keep in mind that you can learn from some of what they are doing.   You look at the bad behaviors and disregard but look at what works and adapt it to what will work for you. Dont be bullied into stopping you from doing the right thing. Go to top Power-Influence-Office Politics: it comes down to your Strategic Relationships and understanding of how you build each one of these elements.

Timing on the LSAT

Timing on the LSAT LSAT Law School Blog You Must Time Yourself When Preparing for the LSAT. It’s one thing to peruse sample LSAT questions at your leisure. It’s quite another to take a test under the ridiculously strict time constraints. In fact, I would say the single most important preparation tool is to take sample tests under timed conditions. This point cannot be overestimated. You must time yourself at points throughout your prep, and the best way to do that is with old LSAT tests. 1.Why time yourself I learned this lesson the first time I took the LSAT. My preparation then consisted of buying an over-the-counter prep book and working through questions leisurely on my lunch hour. I was doing great! (As would many people, with no time constraints.) I never actually timed myself. After all, I’d always done well on tests and I work well under pressure. On the day of the exam, when they called the five minute warning on the first section, I about had a panic attack. I was hyperventilating as I frantically made guesses at the last questions. So here’s how you learn from my mistake: Throughout your preparation, periodically time yourself. First with individual sections (which means setting a timer for 35 minutes and being strict about adhering to it); later you can simulate an entire test. There are two schools of thought on the approach to timing: (1) Some believe you shouldn’t time yourself too soon; that you should first learn approaches to the different sections at a slower pace, and then later learn to speed it up; (2) Others think you should launch right into the fast-paced approach. (There is a third way â€" the Kaplan approach is to teach you to work at a pace even harder than the actual test, sort of like training marathoners up at high elevations). Whichever approach you pick, all agree that you must time yourself before the actual exam. 2. Why Use old tests My first over-the-counter prep book was published by a nationally known test prep company. But I can tell you, the sample questions they had were not very much like the actual test questions I faced on the LSAT. The second time I took the test, I found out you can order old tests from the Law School Admission Council, and I ordered about four or five of them. Do this. As soon as you begin thinking about taking the LSAT. There’s nothing like getting it straight from the horse’s mouth. You can usually get one old test online for free; but you’ll want a few more. You’ll want to take at least one complete test all in one sitting; you’ll also want several individual sections to time yourself on throughout your prep work. Buying old tests is not expensive at all. Make sure you do it early, and then â€" more importantly â€" make sure to sit down with that timer and time yourself!

Business English 10 Tough Job Interview Questions

Business English 10 Tough Job Interview Questions One of the main reasons people come to us for English classes is preparation for job interviews in English.

7 Smart Tips to Know When Taking an Online Course

7 Smart Tips to Know When Taking an Online Course via Pixabay Set Up Your Technology A week or two before you start your online course, make sure you have the technological support that you will need. This could be a computer program, webcam, microphone, or a certain computer in general. It may take some time to get these devices if you don’t already have them. If you do have everything you need, run a quick diagnostics and check to make sure everything is in working order. Nobody likes showing up to the first class unprepared! Hold Yourself Accountable When taking an online course, you need to hold yourself accountable for completing assignments and learning the material provided. It’s easy to forget about an assignment because you aren’t in a classroom talking to your classmates about the course. It’s also easy to decide not to pay attention to your online course. Whether the set up of the course is through readings, videos, or live online classes, it’s important to dedicate your full attention to your instructor. Find a Designated Study Space Claim a designated study space when you take your online course. Treat it as if you are going to a classroom for every class meeting, but you get to choose the spot. Maybe it’s a couch in your living room. It could be your favorite coffee shop on campus. Or it could be right from your desk in your room. Choose a space where you can concentrate on your online course and where you won’t be distracted. You may feel tempted to lay in bed and take your online course because it’s super comfortable. That could cause you to pay less attention to the material, though. It’s best to find a productive space where you know all of your attention will be on your online course. Take It With a Friend Stay motivated when taking an online course by taking it with a friend. When you know someone else who is learning the same thing and going through the same experience, you can help each other stay motivated and answer any questions that may come up. Since there isn’t face-to-face interaction with other people taking the class, it’s nice to have a friend to study with before a big exam or work on a project together. Make a Schedule Every online course is different. Some may require you to “meet” with the professor at a designated time each week while others can be taken at your own pace. When an online course can be taken at your own pace, it’s important to make a schedule and dedicate specific times to learning and studying. Set a goal for when you would like to finish the course and plan out how many chapters or modules you will have to complete each week and how long they should take you. Write it down on your calendar and make sure to stick to it! via Pixabay Connect with the Instructor Students taking an online course may be under the impression that because they are not seeing their instructor face-to-face means that they are not as dedicated to their students’ success. It’s important to communicate with your instructor, especially if you have a question or concern with the online course. Some courses may offer instant chat features to contact your instructor quickly. If not, just send an email! It’s as easy as that! Know That Online Classes Aren’t Easier People are under the impression that an online course is easier than taking an in-person class. This isn’t always the case. It may be much harder due to the content material or the set up of the course. So, don’t go into the online course assuming that it is going to be easier and think that you can just coast your way through. Be prepared to work hard and dedicate a lot of time to studying and completing assignments. Succeed in an Online Course When you go into an online course knowing that it may be harder than an in-person class, dedicate time and a study space, and hold yourself accountable for all of the work, you’ll definitely pass! Don’t be afraid to reach out to the instructor with any questions too!

Avoiding Student Loan Repayment Traps

Avoiding Student Loan Repayment Traps Image via pexels.com 1) Be as knowledgeable as you can regarding loans   One of the biggest issues that arise from student loans is students lack of general knowledge when it comes to student loans and how to repay them. When you first accepted your student loans, you should have gone through loan counseling that offered a quick lesson on student loans and how to repay them. Unfortunately, many college students breezed through it without much thought or took it so long ago that they forget the majority of what they had learned through loan counseling. There are plenty credible articles and pages dedicated to shedding light on student loans and their repayment process take advantage. Once you have general knowledge of student loans, get more specific information on your own loans: the total cost, interest rates, payment deadlines, etc. If you need more information specific to your student loans, enlist the direct help of your lender to receive statements holding all the information you will need. Keep any and all statements handy so they are easy to find when future questions come up. 2) Be sure about your   interest rates  and how they can vary depending on the loan Interest rates on your student loans will vary depending on the loan type and the first disbursement date of the loan. Make sure you are fully aware of what student loans you have accepted and the interest rate associated with each one When repaying your student loans, some of your payment will be applying to your principal balance. To be sure about the exact amount going toward your principal balance, contact your loan servicer to confirm your payment. Your loan servicer will be the company that collects your student loan payments, responds to any of your questions, and performs miscellaneous administrative tasks associated with federal student loans on your behalf. 3) Keep up with deadlines and dont rely on reminders from others   Another big issue that students often encounter when it comes to student loan repayment is failing to repay their student loans on time. Its easy  to forget one small deadline when there are countless other things going on in your life, especially when loan servicers will not be sending you constant reminders to keep up with your student loan payments. Likewise, you dont want to just rely on yourself to remember deadlines mentally as it will be easy for payment deadlines to slip your mind when a friend is getting married the same week or when you are rushing to pay rent. Write your deadlines everywhere you would plan your other priorities out your personal planner, a wall calendar in your office, your Google Calendar, or Post-it notes on your fridge. 4) Remember that putting off paying loans will ultimately mean more interest in the long run It may seem simple enough interest rates add on to your principal balance as time passes. The more time that passes, the higher amount you will have to repay on your student loans. Unfortunately, many college students and graduates forget about this when they actually have their own student loans to pay. When you are repaying your student loans, you may hear the terms forbearance or deferment, which will allow you to temporarily reduce monthly payments or temporarily stop paying payments. Understand the difference between the two before agreeing to commit to either one. Deferment will mean that you may not be responsible for paying the interest that will accumulate during your deferment period, depending on the type of loan you are deferring the payments on. With forbearance, you will be responsible for paying the interest that accumulates on all federal student loans. The eligibility for both varies, but if you are enrolled in college or career school at least half-time, you will most likely be placed into a deferment period automatically for the duration of your enrollment. Take caution into when your deferment period ends (along with post-graduation grace periods) so that you can avoid missing payments once they are expected to be paid once again.

My Teaching Philosophy

My Teaching Philosophy My Story: School and How I Learned I Wanted to TeachMy earliest memory of my education was in my kindergarten classroom. I remember my teacher, and how she would play “Twinkle Twinkle Little Star” and “Oh When the Saints” on her xylophone to signal to the students that she wanted them to come to the rug. No words were spoken, it was just known by all the students in the class that this was our cue.This experience has stayed with me all through my schooling, and will remain within my future as an educator. As a student, I always enjoyed school, enjoyed learning and enjoyed the atmosphere. This feeling continued, and even when school required more studying and less exploration, I still saw its value. I do not know how this this appreciation came to me, if it was instilled in me by my family, my teachers, if it came naturally, or possibly a combination, but I was grateful it was there. Entering the field of education, and having gained experience working within schools, I have s een that this experience is not typical. I have met different students with many different stories, and not one of them is the same as another. As a child it is more difficult to see these discrepancies, but looking back on my experiences in school, as well as what I have learned since then, it is clear to me that there is no typical experience, no cookie cutter student and no one way to teach. Each teacher must forge their own path to discover how they will inspire each of their students. “It is the supreme art of the teacher to awaken joy in creative expression and knowledge” (Albert Einstein) and that is my aspiration as a teacher. How My Philosophy Helps My StudentsThe most vital, and foundational philosophy that any teacher, of any grade, demographic or subject area needs to consider is how the student views themselves within the classroom community that you have created. If a student feels that they are not valued as part of this community, or that they are not a positive contributor to this community, their success academically, socially and emotionally is compromised. Classrooms today represent a wide range of diverse learners, whether it be students with disabilities, English Language Learners, minority groups or students who may just feel ostracized or “different”. It is our job as teachers to awaken the joy in students within this community. Give students to opportunity to show what makes them special. Value their differences and celebrate them. Give every the student the opportunity to do something great, something that will make them feel proud of themselves, and feel that they are a part of the group of students around them. This will be different for every student and may be easy, or may take a lot of trust, support and encouragement. However, that one small moment of being included, involved, and belonging may be what makes the difference for a student to succeed and awaken the inspiration within them.Once a student feels comfortable an d valued in their classroom community, the foundation of learning can begin. A student will be more open and willing to learning new things if they are comfortable. Students will be even more willing to learn and experience new things if they can see the value that the learning has to them. A student is more likely to see the value in learning and be actively involved if they can identify how the material can relate to and help them in their own lives. How do we expect students to blindly follow teachers and they teach lessons, but do not understand why they are learning what they are learning? Tips: How What I've Learned Can Help Other Teachers, Tutors, and StudentsTeachers need to take the time to explain to students on why what they are learning matters to them, and for each student, that may be different. This element does not need to be overtly repeated in every situation, it may be subtle and may be woven into the lesson or activity you area leading. What is important is that students can make connections to what they are learning in the classroom to real life experiences. This connection does not only inspire them to learn, but enables the learning process by making that connection and solidifying what that student is learning. Furthermore, to ensure that a student’s interest and learning continues to grow, teachers must make the time to pursue topics that students find interesting themselves. With curriculum standards and state requirements, teachers often tend to avoid migrating from the strict curriculum. Does that mean if a student or groups of students show a unique interest in a topic not specifically outlined in a framework that we, as teachers, should ignore it? Or does it mean that we, as teachers, should recognize this opportunity for curiosity and learning and allow students to pursue interests. It is not impossible. Any topic or idea can be adapted to work within a classroom setting. Teachers need to be flexible and adaptable. We need to gauge student interest and seize opportunities when we see them. Teachers need to “awaken joy in creative expression and knowledge” within their students to help ensure their futures are bright.“Everybody is a genius. But if you judge a fish by its abili ty to climb a tree, it will live its whole life believing that it is stupid.”
