titrate it further opening the burette very slightly, allowing acid to be added more slowly into the solution. Carrying out titrations is a skill that develops with practice, more repetitions will lead to improved results, both in accuracy and precision. Both methods are the most accurate, considering the equipment available.
Every gun owner wants to shoot accurately, but there are several factors in both the gun and your shooting style that can negatively affect precision and accuracy. Having poor accuracy does not amount to simply having a poor gun or being a bad shot. It's usually a culmination of several factors in both the gun and the shooter that makes poor accuracy so common. The good news is that you can improve your accuracy with some very simple changes and considerations. Gun Selection All guns have their
1.Explain how you will ensure that the titration is carried out accurately The burette and pipette I’m going to be using should be rinsed out with the solutions they are going to contain. After filling the titrant solution, I have to check the tip of the burette for any air bubbles, if it contains air bubbles the volume readings will be incorrect. Always rinse out the conical flask with distilled water because normal tap water contains ions, this will affect my results. Tap water have chemicals
Rosalind Brewer is the Chief Executive Officer of Sam’s Club. However, many do not know that her undergraduate area of study was chemistry.

She worked at Kimberly-Clark for twenty-two years. She gradually became the president of the global nonwoven fabrics business. In 2006, Walmart invited her to head stores
The Housekeeper and the Professor: Nature is Man, Math is Neither In the Japanese fiction novel written by Yoko Ogawa, The Housekeeper and the Professor focuses primarily on how family is not always bound together by blood. In the year 1975, sixty-four year old mathematician who once was a professor, gets into a horrific accident. Because of this accident, he encountered serious brain damage, primarily in the part of his brain associated with memory. His memory now only lasts about eighty minutes
Countless time teachers encounter students that struggle with mathematical concepts trough elementary grades. Often, the struggle stems from the inability to comprehend the mathematical concept of place value. “Understanding our place value system is an essential foundation for all computations with whole numbers” (Burns, 2010, p. 20). Students that recognize the composition of the numbers have more flexibility in mathematical computation. “Not only does the base-ten system allow us to express arbitrarily
Matchstick Staircase Investigation Introduction This investigation is based on the 'number sequence' and I am going to make further more matchstick staircases for this investigation. Investigation to find out the number of matchsticks on the perimeter in a matchstick staircase using the GENERAL RULE. I have drawn 6 matchstick staircases on the graph paper and I am going to put the number of matchsticks on the base, number of matchsticks on the perimeter, total number of matchsticks
Algebra Tiles and the FOIL Method Algebra is one of the most critical classes a mathematics student takes. In this crucial course, the student must make the jump from concrete numbers and operations to variables and uncertainty. Unfortunately, this area of mathematics is where most students lose interest in mathematics because the concepts become too abstract. The abstractness frightens students and this fear is where the typical “I hate math” attitude comes from. Educators need to be aware of
There are many different ideas as to how technology should be used in the mathematical classroom of today. There are those who believe that students will not learn as much if they use technology such as computers and calculators, and there are still others that believe this technology can benefit students if used in the proper way. After reading many articles on the use of technology in the mathematical classroom, I have to agree with NCTM’s Technology Principle, which states that “technology
According to the website Mathworld, an outlier is “an observation that lies outside the overall pattern of a distribution” and it usually “indicates some sort of problem.” Malcolm Gladwell, author of “Outliers,” defines an outlier as “something that is situated away from or classed differently from a main or related body” or “a statistical observation that is markedly different in value from the others of the sample.” That being said, Gladwell’s definition of an outlier is partially consistent with
Elderly people :- One of The most essential outcomes of Monopoly for children is the mathematical learning. By playing Monopoly, the child acquires the basic mathematical operations such as, division, subtraction and so forth. Although, all these arithmetic operations will be taught in schools but the way they have been conveyed in Monopoly more fun and entertaining which as a result of that will make math more beloved and interesting subject to children. For example, Mathopoly is a game based on Monopoly

Introduction: The purpose behind this briefing paper is to provide the Secretary of State for Education with an idea as to how the Smith Report, 2004 “Making Mathematics Count” has changed Maths education in England. It is important that the Secretary of State for Education to understand how important the Smith Report has been to the advancement of Maths education and what
Introduction The compendia monographs are generally considered reliable sources for the methods of analysis of both the raw materials (Active Pharmaceutical Ingredients, API’s and Excipients) and Finished Drug Products (FDP). However, because there are so many factors involved during the analysis, this includes for example the reagents grades and suppliers, different instruments variations, and the analysis personnel, therefore, double check of the mentioned method of analysis to confirm that it
My pedestal quality lies in the area of mathematics. It polishes my academic armor and sharpens my sword of educational merit. Mathematics is the backbone of my academic figure. Arithmetic and functions come like breathing and a math challenge is always appreciated; however, in no way is my prestige in math providing even the smallest level of interest for me. In fact, mathematics to me is comparable to a wrench in a toolbox: useful when needed, but otherwise useless. Nevertheless, my understanding
Introduction In 1976 Skemp published an important discussion paper spelling out the differences between relational and instrumental understanding as they apply to mathematical teaching and learning. Skemp highlights two faux amis, the first is understanding. Skemp defines understanding in two ways: 1) instrumental understanding and 2) relational understanding. The second faux amis is the word mathematics which he describes as two different subjects being taught. I have considered Skemp’s article
When I was fourteen years old, I learned algebra. My algebra teacher wasn’t the best. My mind didn’t connect with the teachers’ lessons and textbooks too well, and math was one of my weakest subjects. I would walk into my algebra class every afternoon wanting to run right back out. This was the first time I began struggling with math at a high level of difficulty. All my life I had been used to getting 0Bs and at times even As in my math class, however, all of this changed once I got into algebra
strengths, the common measurements can be considered as non-invasive, inexpensive, and suitable methods for evaluating the nutritional status in population studies. However, many anthropometric techniques are dispose to errors that could reduces their precision and influence on their accuracy. (Sicotte et al, 2010; WHO, 2000) 1.4 Aim of the study The aim of this study report was to interpret and appraise information related to nutritional status from measures including height, weight, waist circumference
Prompt 1: A theme that I have noticed in lab that has stood out to me is the importance of being both accurate and precise with your measurements while conducting and experiment in the lab. Given the fact that I only had one chemistry course in high school, I was unsure as to what I should prepare for with a college level chemistry course as well as the lab that went along with it. The one skill that my high school chemistry teacher always scrutinized was the ability of his students to be both accurate
glassware, and how we should handle the laboratory equipment. The accuracy and precision of a particular type of glassware is important because it allows for accurate measurements when performing different experiments. It also allows us to differentiate between glassware that is better for containing substances versus glassware that can deliver substances more accurately. In order to measure the accuracy and precision of the different types of glassware, we first chose seven different types of glassware
