Chemists Safety Before Leaving The Laboratory

Chemist's Safety Before Leaving The LaboratoryIt is one of the most important chemistry librarian practices to keep the chemical building safe from others and that is why safety is the foremost thing that needs to be followed before leaving the chemistry lab. Here are some safety practices which can help you avoid any untoward incident that can happen while you are operating your chemistry laboratory.Do not forget to clean the chemical area before you leave. Even if the work area is isolated from other areas, remember to clean it before leaving the lab. Chemical cleaners or steam cleaners should be kept at the door of the laboratory.Keep the light on when you leave the laboratory. The darkness can create a dangerous situation in the room. If there is a power cut in the room, turn the lights on. If the lights are switched off, other people might be outside your laboratory, so light can make them unsafe to enter the laboratory.After your laboratory is finished working, remove all the c hemicals from the chemical area. The chemical area is generally an area where the chemicals are stored. Do not store them in a closed container, in the same place where they are being used.Close all the doors to the chemical area, so no person can enter the laboratory. Make sure the door is locked tightly. There should be a sturdy lock for the laboratory. The locked door will prevent any entry into the chemical laboratory, while the chemicals are being used.Another one of the safety practice to follow is to label the closed containers when they are not being used. If it is not used for more than three days, label the container with the date when the container was emptied completely.These are just few safety practices of the chemist's safety which are recommended before leaving the laboratory. All those people working in the laboratory should follow these safety practices to ensure a safe lab environment. Keep the chemicals stored under lock and key, to avoid getting into any mishap or any injury in the laboratory.

A Day in the Life at Brigham Young University

A Day in the Life at Brigham Young University The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Lia is a New York City tutor specializing in ACT prep tutoring, Reading tutoring, Biology tutoring, and more. She is a 2009 graduate of Brigham Young University with Bachelors degrees in both Visual Art and Physiology Developmental Biology. See what she had to say about her alma mater: VT: Describe the campus setting and transportation options.How urban or safe is the campus?Are there buses or do you need a car/bike? Lia: Brigham Young Universitys campus is set in a archetypically picturesque location, with looming overhead mountains grandly displaying the seasons, and nearby Sundance serving as the perfect vista for winter or summer past-times. The surrounding town, Provo, is small and extraordinarily friendly. A stroll down University Ave toward Center Street acquaints you with many of the small businesses and locals. After freshman year, most students live off campus, with many commuting mostly by bike or by foot. South of campus is full of BYU-approved housing, including apartment complexes and multiple-room houses; large apartment complexes and resulting communities abound all around the edge of campus as well. VT: How available are the professors, academic advisers, and teaching assistants? Lia: Depending on the program, of course, almost every professor, TA, and adviser is as available as you proactively seek them to be. Every professor and TA holds office hours, and some classes hold regular extra labs or office hours during which TAs guide you through difficult problem sets or offer other coaching. English and writing tutoring is regularly available in the library through the English department. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Lia: The dorms mostly consist of freshmen, and many of these freshmen form strong groups, usually within their church ward, that last throughout college. Every dorm building has its own culture, with some offering more socialization than others (for example, those that include six students per unit and have individual kitchens usually have less social functions; those that include 1-2 students per unit, without individual units, usually have more). VT: Which majors/programs are best represented and supported?What did you study and why? Did the university do a good job supporting your particular area of study? Lia: I double majored in Visual Arts: Studio Art and Physiology Developmental Biology, with a minor in Chemistry. I began college intending to apply to medical school, but decided to join the Visual Arts program my junior year and fulfill both degrees. I found that the programs were incredibly different; where the Physiology Developmental Biology program (underneath the Biology department) circulated a large number of students every year and had lectures with student bodies ranging from 50-200, the Visual Arts Department was extremely intimate with classes ranging from 5-20 students. As a result, I was able to get a lot more support in my Visual Arts classes than I was in my science classes, as well as develop stronger mentor relationships. While BYU has an excellent variety of programs and support is available when asked for, its good to do research on class and program sizes to gauge what would best meet ones needs. VT: How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Lia: There arent any sororities or fraternities on campus, but church wards often provide a lot of social structure. As a freshman, its almost essential to live in the dorms and attend an assigned ward to really live out the social experience. There are also a lot of campus functions and activities, often specifically geared toward freshmen, but these are also often attended by ward groups. VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Lia: BYU has a top ranking business school and thus attracts a lot of attention. The Career Center is available as a general support, but usually refer students to specific departments for more specific advice and support. VT: How are the various study areas such aslibraries, the student union, and dorm lounges? Are they over-crowded, easily available, spacious? Lia: The Harold B. Lee Library is an enormous resource with an incredible selection of books, periodicals, and digital resources. Because the H.B.L.L. is so enormous, there are many different rooms for students to reserve for study groups and areas to study individually, as well as computers for use. The student center and dorm lounges are also spacious and comfortable, but most students group in the library. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Lia: Provo, Utah is a small town with several larger, settled businesses and many small businesses. While campus is situated just a half mile or so from the center street of downtown Provo, many students congregate mostly on or within campus. Downtown Provo is a rich, cultural community, however, with great gallery strolls, small businesses, and a thriving music scene, and the students that explore it often integrate into it quickly. Other than the downtown area, which is easily traversable by foot, many students enjoy hikes, bike rides around Utah Lake, weekend trips to Southern Utah, and shopping in Salt Lake City, which is an hours drive north. VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Lia: BYU has approximately 30,000 in its student body, lending to large class sizes in most general courses. While the class sizes werent always frustrating, it was also a high priority for me to find courses that offered smaller group sizes for purposes of discussion and stronger support. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Lia: My favorite class at BYU came in my last semester there: Special Problems in Art. In the midst of this course, I was able to make proposals for art exhibits that were particularly experimental and receive approval to install them. One such experience involved a sound art installation, in which a fellow student and I placed recordings of various familiar sounds in ceiling tiles, and set the recordings to play at an interval of four minutes or so. It was amazing watching casually as passersby heard lawn mowers, scrapes, and breaking glass as they walked to class! Check out Lias tutoring profile.

Learning Styles - Private Tutoring

Learning Styles BobbiM Mar 26, 2014 Now lets talk about different learning styles. Learning styles? Yep. The different ways people learn. For me personally I learn easier by seeing things visually. Read these descriptions of each learning style and decide how you learn best. Visual learners: those who learn best by watching or seeing. Visual learners like to be shown how to do things and often learn best through diagrams or by using imagery. If you are a visual learner,(like me!) if someone asks you how to spell a word, you probably have to write it down yourself first, rather than simply trying to spell the word in your head or out loud. Are you a visual learner? Auditory learners: those who learn best by listening or speaking. Auditory learners can learn easily through listening to lectures or by talking information over with a peer. If you are an auditory learner, you probably rarely miss a class lecture and you may participate in study groups for many of your courses. You may rehearse information by saying it over, either to yourself or out loud. Are you an auditory learner? Kinesthetic learners: those who learn best by touching or movement. Kinesthetic learners generally learn best through writing or even typing things out. If you are a Kinesthetic learner, you may rehearse information by writing it several times. You also may enjoy lab courses where there is a hands-on approach to learning. Are you a Kinesthetic learner? Excerpt from College Success Strategies by Sherrie L. Nist and Jodi Patrick Holschuh.

SAT Math Solving Impossible Math Problems

SAT Math Solving Impossible Math Problems ACT SAT Prep and College Admissions Blog The SAT sometimes approaches math a bit differently than we’re used to in math class. One of these differences in approach is in the way some SAT math problems ask us to solve for relationships between variables, rather than the value of one particular variable. These problems can seem very challenging, or even downright impossible, at first glance, because they often give us multiple variables but only one equation. One thing we learn in math class when studying systems of equations is that in order to solve for 2 variables, we usually need 2 separate equations; to solve for 3 variables, we need 3 separate equations; and so on. Certain SAT math problems will appear to violate that general rule and ask us to do something that’s supposed to be impossible, like solving for 2 variables with only 1 equation. When we look more closely at such problems, though, we realize that the SAT is not really asking for the value of each individual variable involved. Instead, we’re asked to find the value of the sum, product, or some other relationship involving 2 or more variables. Let’s look at an example of such a problem: If 4x + 7y + 1 = y â€" 2, What is the value of 2x + 3y? A. -2 B. -1.5 C. -0.5 D. 2 E. 4.5 Explanation and solution: We’re given only one equation, but it involves 2 unknowns: x and y. We really don’t have enough information to solve for the value of x and/or the value of y, but fortunately, that’s not what the question asks us to do. Instead, we are asked to find the value of a sort of relationship that involves both x and y together: 2x + 3y. To do this, we algebraically manipulate the equation that’s given. Instead of trying to isolate x or isolate y, we try to isolate the quantity “2x + 3y”. To do this, we can first subtract y from both sides of the equation, and then subtract 1 from both sides, so that the equation now looks like: 4x + 6y = -3. To finish isolating “2x + 3y”, we divide both sides of the equation by 2 and obtain: 2x + 3y = -1.5. So the correct answer choice is “B”. Let’s look at another example: If the average of x, y, and z is 12, what is the value of 3(x + y + z)? A. 12 B. 24 C. 36 D. 72 E. 108 Explanation and solution: To obtain the average of x, y, and z, we would need to add the 3 numbers together and then divide the resulting sum by 3. Since we are told that their average equals 12, we can express the information as an equation: (x + y + z)/3 = 12. Multiplying both sides of the equation by 3, we obtain: (x + y + z) = 36. To find the value of 3(x + y + z), we can again multiply both sides of the equation by 3 and find that 3(x + y + z) = 108. The correct answer choice is “E”. Notice that in the problem we just solved, we did not solve for the individual values of x, y, or z; that would have required more information than we were given.

Back to the post, I often see people on their phones, even at the beach, so why not spend some of your technology time studying your way into college? Check out these 5 fantastic SAT apps to help you get started on your summer SAT journey (READ: Summer Spent Well: What Are Colleges Looking For?). 1. IntelliVacab lite for SAT Okay, so have you ever had someone like me show up at your door for SAT tutoring and they ask you, “so how many vocab words have you learned so far?”. And you think to yourself, “Um none”. This is totally normal and actually very common. Although I strongly recommend that the best way to learn new vocab is in-context (Your Irvine SAT tutor will help explain this to you), the reality is that some vocab words found on the SAT are words that you will never, ever use again (unless you become an SAT tutor or go work for the College Board). For those words you just have to sit down and learn them. You could make 3,500 flash cards (no thanks) or you could try this app. IntelliVocab lite for SAT is designed to learn your patterns of weakness and which words trip you up time and time again and then focuses on them. That’s pretty smart huh? As an added bonus it’s FREE. 2. Edupath SAT Prep and College Search This app helps you track your progress as you study. It would make a great companion study tool to your tutoring sessions. Edupath SAT Prep will tell you which areas that you need to focus on and then you can tell your tutor what your weaknesses are and you can work on them together. As an extra feature, this app helps you find colleges that might fit your goals and career needs. So many students are overwhelmed with the hundreds of choices of colleges and universities. Most students don’t know which schools will accept their current SAT scores. Also, knowing where you want to go to college can help you figure out the specific SAT scores that you need.Pretty cool! Also FREE. 3. SAT Up SAT Up can actually help you correct the problems that you answered incorrectly. This app will take you through the process step by step. For many math students, missing even one step can mean the difference between up to 100 points. This is also a great companion study tool. FREE! 4. SATLadder SATLadder allows users to compete and challenge other real life test prep students. This is a great way to see how you stack up to other students taking the SAT this fall. Let’s face it, colleges will be doing the same. 5. Vocab Ahead This app, Vocab Ahead, features videos where the vocabulary word is pronounced for you. Users also get a definition and hear the word used in a sentence. Hearing a word in context makes it easier to remember and it never hurts to hear new words pronounced out loud. The reality is that students who are taking the SAT in October should be well into their summer study program but if you haven’t started yet now is definitely the time. Even 25 minutes a day can really help you get closer to your college goals. I recommend that you use these apps on the days that you don’t see your SAT tutor. If you are planning to start tutoring this fall (for the December SAT) then get started with these apps now to give you that competitive edge when you start regular study sessions in September.

What Is The Difference Between Accuracy And Precision in Chemistry?

What Is The Difference Between Accuracy And Precision in Chemistry?In chemistry, there is the difference between accuracy and precision. This difference is important because both can cause you to perform incorrect analyses of samples. The correct analysis requires a chemist to do their best, but a mistake can often lead to bad science.The issue is that many chemists may be too concerned with accuracy. With precision, they are able to get to work on samples quickly. They will also make more mistakes, which increases the chance that they will be caught. This leads to an inaccurate assessment of the nature of the sample.So, what is the difference between accuracy and precision? The answer lies in the fact that accuracy involves a whole system. It includes the accuracy of your work and your ability to implement the correct procedures. Precision involves different things such as setting up a proper sample analysis to get the measurements.If you have these two errors, then you will not be able to be an accurate scientist. Either of these can lead to the missing of a few relevant elements. The improper analysis of the sample can lead to the missing of a material that you were trying to detect.So it is not the case that you can work with precision. The problem comes from not making the necessary corrections when you are doing your calculations. This means that in this field, accuracy is not enough to ensure that you have a good test, but it is also important that you are taking proper measurements.With accuracy, you are more likely to get things right. With precision, you are less likely to get the measurement right, but it is the case that you will still get it right.These differences help explain why precision is more important than accuracy in chemistry. You need both accuracy and precision to be successful in your career.
