Things You Learn in Chemistry

Things You Learn in ChemistryOne of the best things you can learn in chemistry is that you can be a chemist! Even if you're not sure you're going to go into that field, or you want to get a degree in chemistry, you'll find that you can make a career from it. You just need to know what steps to take and when to take them.When you first start learning about chemistry, you should start with a good introductory course. This will help you learn everything you need to know about basic chemistry. You need to know that there are molecules and that they combine together to make all the different chemicals we use every day. Some of these things you learn in chemistry include, elements, acids, bases, fuels, solid and liquid, solids, liquids, volatile solids, gases, acids, bases, enzymes, hydration, solvents, and catalysts. If you understand the basics of this field, you'll find that you have a great advantage over most people who have a lot less knowledge about chemistry.Many times, people want to become a chemist because they love the idea of working with the basic science of chemistry. This can be an extremely rewarding job. You'll have a lot of options to choose from because it's a very technical field, but you also have a lot of opportunities to help people. Working in a lab may be one of the few ways you can help people, especially if you do it for a living.If you really want to learn more about chemistry, you'll have to apply yourself to it. You can always sign up for courses, but you need to study in order to do well. You also need to spend time on doing hands-on projects.Start by doing a research project. This can be something you want to do for a big company. You'll need to find out how to measure things, how to treat samples, and how to make test kits. Once you've done all of this, you can then start looking at how to become a full-time chemist.At this point, you need to decide what type of degree you want to earn. You can go to a traditional school or you can g et online classes. The first choice will give you more options in terms of the way you can get your degree, but if you can't afford to go to a traditional school, you may have to get online.If you want to make a good living from your knowledge, you need to make the best use of the time you have.

Adding fractions with unlike denominators

Adding fractions with unlike denominators The basic mathematical operations in math are addition, subtraction, multiplication and division. Addition is finding the total sum or combining the given numbers or quantities. Addition is denoted by the sign +. In addition order of the numbers doesnt change the answer. Fraction is usually written in the p/q form. Here p is the numerator and q is the denominator. The denominator of a fraction cannot be equal to zero i.e. q not equal to zero. For adding two fractions with different denominators the LCM needs to be calculated. Example 1: Simplify and find the answer by adding the two fraction numbers 3/5 + 1/2? Solution: Given is to find the sum of 3/5 + 1/2. The fractions have unlike denominator. So the LCM of 2 and 5 = 10. The fractions are written using the LCM = 1/2 + 3/5 = 5/10 + 6/10 = 11/10. Therefore, this gives adding the two fractions 3/5 + 1/2 = 11/10. Question: Multiple choice question (Pick the correct option.) What is the sum of adding the two fractions 1/3 + 1/4? a) 7/12 b) 5/12 c) 2/12 d) None of these. Correct answer: option a. Given is adding the fractions 1/3 + 1/4. Here both the fractions have unlike denominators. The LCM of the denominators 3 and 4 is 12. The denominators can be made alike by the LCM 12. This gives 1/3 + 1/4 = 4/12 + 3/12 = 7/12. Therefore, this gives adding the two fractions 1/3 + 1/4= 7/12.

ACT Science Tips

ACT Science Tips Are you concerned about ACT Science? Even if you are not strong in the scientific areas assessed biology, chemistry, Earth/space sciences, and physics you can still perform well on this section. You may also want to consider enlisting the help of anACT science tutoras well as taking a few ACT practice teststo help you prepare. The ACT primarily measures your ability to reason scientifically, not your recall of concepts. Here are several tips for the Science section: 1. Write on the exam The majority of questions involve reading lengthy passages or viewpoints, and the involved information can be dense. Underline or circle key terms that are frequently utilized, and mark key points. Writing on the test has two purposes: it keeps your mind active while you read the passages, and it highlights important parts that you can reference when you address the questions. Here are some great tips on how to prep for the ACT science section. 2. Eliminate With more difficult questions, it is often simpler to identify the wrong answers than to choose the correct ones. Eliminate responses you know are incorrect, and probability will be in your favor even if you must guess between the remaining choices. If an answer seems correct, mark it but read the other options you may locate an even better response. 3. Summarize This strategy is very useful with Conflicting Viewpoints questions: separate views about the same subject are provided, and seven questions test your ability to evaluate the argument and differentiate opinions. After reading, summarize as quickly and accurately as possible the main argument of each viewpoint. Note where the authors disagree, but also where they agree. When answering questions, refer to your summaries first, and then consult the original passages if the answer isnt apparent. 4. Translate the question The ACT measures your ability to interpret complex or confusing questions. A wrong answer will frequently appear appealing because of a difficult question. Do not permit a strange question to phase you. Instead, translate the question into your own words, and use it to determine the correct choice. 5. Ignore the answers, briefly Not only are questions complex, but the answers on the ACT are intentionally constructed to mislead you. It can be beneficial to initially cover up the multiple-choice answers and attempt to respond to the question in your own words then, with the answer choices revealed, choose the one that most closely matches your own response. This method works best with general questions on the Research Summaries and Conflicting Viewpoint sections problems that ask about the general purpose or main idea of a passage. 6. Skim charts and graphs Part of the ACT Science section, Data Representation, assesses your ability to read and interpret scientific charts and graphs. Spend several seconds examining the chart, noting the important parts the title, subtitle, and units then move on to the questions. You likely will not have to answer questions about every part of the chart or graph, and you will certainly have to refer back to them regardless. Do not waste precious time at the beginning analyzing them. You may want to take a look at these tips on how to improve your ACT scoreas well.

Online Definition of Geometry Tutors

Online Definition of Geometry Tutors Geometry is a section in Mathematics which deals with different lines, angles and predominantly is the study of various shapes and their measurements. When two or more lines are connected, various kinds of shapes are formed and those shapes are called by different names like squares, rectangles, triangles etc. These geometric shapes have different side lengths, angles areas, volumes etc. and the study of all these measurements is Geometry. Geometry constitutes one of the most important sections in math and its concepts are used most of the time in our daily life. Example 1: Calculate the area of a triangle which has base side of length 5m and height of 4m? Triangle is a geometric shape which has 3 sides and 3 angles. The area of the triangle is = 1/2 *(base)* (height) Given: Base length of the triangle, b = 5m Height of the triangle, h = 4m This gives, Area of the triangle, A = 1/2 * 5m * 4m = 10m2. Therefore, area of the given triangle is 10m2 Example 2: Calculate the area of a circle if the radius of the circle is 3m. In the given question, radius of the circle, r = 3m Area of the circle is given by the formula, Area = * (radius)2 In the above formula, (known as pi) is a constant == Value of = 3.14 Therefore we get, Area of the circle, A = * (3m)2 == Area, A = 9 = 28.3m2 Hence area of the given circle, A = 28.3m2

How are IB Exams Scored

How are IB Exams Scored From college credit to sharper higher-order thinking skills, the benefits of earning an IB diploma are undeniable. The IB Diploma Programme culminates in various types of IB exams whose grading criteria can seem mystifying upon first review. To avoid surprises come test day, its key to be aware of how IB courses are evaluated. When understanding IB exam scoring, its important to explore the various types of assessments, scoring scales, and passing requirements. Keep reading to learn how individual IB exams are scored. [RELATED: What High School Students Should Know About IB Courses] External vs. internal IB assessments IB assessments are classified as external or internal. External assessments include exams, and are touted for their objective nature. IB external assessments generally involve a combination of the following formats: Case study questions Data response questions Essays Multiple-choice questions (rare) Short-response questions Structured problems Text-response questions. Internal assessments, on the other hand, are evaluated and supervised by teachers. The student and the teacher work closely together throughout the year, and the teacher acts as a mentor while the student develops his or her unique project related to the IB course. Internal assessments may involve the following: Artistic performances Geographical fieldwork Laboratory work Mathematical research. IB exam scoring scales IB exams are graded on a scale of 1 (lowest) to 7 (highest), with only seven percent of IB students earning a perfect score. Accounting for the six IB subject groups, and up to three additional points for Theory of Knowledge (TOK) and the Extended Essay (EE), the maximum score a student can achieve in the Diploma Programme is 45 total points. (Note, however, that you can often complete an IB course without enrolling in the Diploma Programme.) [RELATED: 10 Study Habits to Avoid] IB exam score requirements for earning a diploma Students must accumulate a minimum of 24 total points to earn an IB diploma. Despite the programs demanding nature, most IB students exceed the minimum score requirements. The average score in the IB Diploma Programme is 30 points, and the pass rate has remained close to 80 percent. Students are encouraged to familiarize themselves with the IB grade descriptors, an extensive overview that describes exactly what the test graders look for. Each score is accompanied by a detailed description to help students gauge their performance. In addition, to earn the IB diploma, students must also pass the core, which includes the EE, TOK, and an element called Creativity, Action, Service. Though Creativity, Action, Service does not contribute to the points total of the IB diploma, students are required to demonstrate authenticated participation. The scoring of IB exams is not as complicated a process as it may seem. If you have not done so already, familiarize yourself with the IB exam types and scoring guidelines to prepare for your IB exams.

The Boss 2 Things to Think About - Introvert Whisperer

Introvert Whisperer / “The Boss” 2 Things to Think About - Introvert Whisperer “The Boss” 2 Things to Think About I had lunch with a friend and I was asking about her son who I had helped a bit with career coaching.   She was saying he loved his job and especially had a great boss.   She told me some of the things this boss had said and done.   Clearly, this boss was a good leader. I want to share with you what I shared with my friend simply to give you something to think about in your own career. For as long as I have paid attention to this statistic (which is close to over 20 years) the number 1 contributor to a person’s job satisfaction is: The Boss.   I think most people think it’s the money but money, strangely enough, shows up in #3 or #4 spot but the boss has been at the top spot all the time. If you think about it, it becomes easy to see.   At some point, it almost makes no difference how much you get paid, if the boss is a miserable person, the money can’t make you happy. I think this factoid is important to you for 2 reasons: #1 â€" If you lead others, YOU are responsible for whether or not those people will like coming in to work.   That alone should cause you to pay attention and try to be a good leader.   Things like motivation and productivity are directly tied to this condition. Even if you want to feel no responsibility for how others feel, you need to pay attention to the fact that your team will perform better if they can work well with you.   You will look much better to the executives if your team works great â€" isn’t that worth it? #2 â€" If you don’t like going to work, it’s the boss.   While you know I’m a big advocate of taking responsibility for working well with the boss (and you are), you also must recognize the reality of the situation.   You can’t change another person, nor can you expect for them to wake up and be different.   Unless you think the boss is going to quickly move on from the current job, things aren’t going to improve anytime soon.   Do you want to live like this? Take responsibility for compensating your interactions with the boss.   It could completely change the dynamic. It’s a tough job being the boss.   I know, I’ve done it for years.   It’s also the best job if done right but it’s seriously easy to do wrong.   That’s why there are so many books and classes devoted to leadership and management training. 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.

More Focused with Media

More Focused with Media Your child says that listening to music or watching television helps him or her concentrate when doing schoolwork. But is he or she right? Sitting down to concentrate on homework is hard when you have ADHD. Not surprisingly, kids, teens, and their parents are always on the lookout for ways to make homework less painful. For many families that Ive worked with, arguments often erupt over whether or not the television, music, or other noise should be allowed during homework. Desperate to help their kids get their work done, many parents are willing to make more concessions during homework time than they would for other activities and chores throughout the day. But do things like television and music really help kids with ADHD concentrate? Or are they simply fun distractions? Lets look at what the science has to say. Television: Your child may find homework less painful when he or she is watching television, but chances are his or her work performance is suffering. In a study conducted at a renowned ADHD center, scientists examined the effects of television on schoolwork completion and focus in kids with ADHD.1 When the television was on in the classroom, kids with ADHD, on average, completed significantly less schoolwork than when the television was turned off. They were also off-task more frequently and had to be reminded more often by the teacher to get back to work. Music: Like television, music can help make boring tasks less painful. For example, studies have shown that people will stay on a treadmill longer and find that time goes by faster when theyre listing to music. But is music too much of a distraction for kids with ADHD who need to focus on schoolwork? In the television study described above, the researchers also studied the effects of music and found it to be much less distracting than television. For most of the kids with ADHD, background music didnt have any effect on their performance, and 12% of the kids actually completed more work when they were listening to music! Additional studies of kids with attention problems have demonstrated improved performance on memory tasks when music without a vocal track is played in the background. White Noise: While your child may not be specifically asking to have white noise on in the background while he or she works, research shows that it may actually be helpful for kids with ADHD. A recent study compared the effect of white noise on the cognitive performance of three groups of kids: those with exceptionally high levels of attention, those with average levels of attention, those with low levels of attention2. For the least attentive kids, white noise (at a medium to high volume) significantly improved their cognitive performance. Interestingly, for the kids in the high attention group, white noise worsened their performance. It had no effect on kids with average levels of attention. A handful of additional studies have produced similar results for kids with attention challenges. Bottom Line: Skip the television. If your child wants to listen to music or white noise, then test it out. Does he or she make more careless mistakes on his or her homework, does he or she take longer to complete it? Or, if theres no change in his or her work, but your child seems happier, more calm and content, then that would count as an improvement. Let your child know ahead of time that youll be monitoring his or her progress. Maybe that will even motivate him or her to work better, so he or she can keep the music or background noise around! 1Pelham, W.E., Waschbush, D.A., Hoza, B., Gnagy, E.M., Greiner, A.R., Sams, S.E.Carter, R.L.
