Interpreting The Periodic Table Lab Report

My unknown organism #6 is Morganella morganii, which is a gram-negative bacillus rods commonly found in the environment and also in the intestinal tracts of humans, mammals, and reptiles as a normal flora. (3, 5) This bacterium Morganella morganii, was first discovered in the 1906 by a British bacteriologist named H. de R. Morgan. (2) Despite its wide distribution, it is an uncommon cause of community-acquired infection and is most often encountered inpostoperative and other nosocomial settings. (2, 3) Morganella morganii infections respond well to appropriate antibiotic therapy; however, its

The purpose of this lab was to identify unknown bacteria cultures using various differential tests, and my unknown bacteria is #17. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways, each was used in a way to help recognize those specifics and identify the unknown cultures. The differential tests used to identify the unknown cultures were Gram stain, Catalase, Mannitol Salt Agar (MSA), Blood Agar, Novobiocin, Coagulase, and DNAse (Alachi, 2007).

Bacteria are ubiquitous; they can be found on the skin, in the soil, and inside the body. Because of the very nature of this ubiquity, it is important to be able to determine between different strains of bacteria. An example of this is determining the causative agent for a disease so that the patient will be treated with the appropriate antibiotics. It may be important to determine the bacteria in a certain region, because like with enteric bacteria, it is normal to find them in the digestive tract as they are in a symbiotic relationship with our bodies in this area; however, they also cause opportunistic infections in places outside of the digestive tract to our detriment, such as with a urinary tract infection. Some strains of bacteria are common to nosocomial infections, and identifying these bacteria as such helps create the guidelines for healthcare workers in antiseptic technique. All of the morphology and characteristics of each strain of bacteria help us to better understand the role of bacteria in the body as well as helps us understand how they can cause illness, and what treatment regimen to set in place. In lab this semester, a sample of unknown

Triple Sugar Iron Agar test, there was a gas production seen in the media. The media was yellow slant and yellow butt indicating glucose, lactose and/or sucrose fermentation with acid accumulation in slant and butt. For sulfur reduction, it was negative since it did not turn black in color indicating no sulfur was reduced.

Reviewing Elements of Chapter 12 of the Disappearing Spoon Sam Kean, the author of the New York Times Bestseller the Disappearing Spoon, opens the 12th chapter of his narrative by stating that “The periodic table embodies our frustrations and failures in every human field: economics, psychology, the arts, and… politics” (Kean, 203). Kean, being an english and physics major, observes that the periodic table, our most treasured accomplishment as a race as he puts it, is much more than just a jumble of random letters pertaining to a specific scientific field but, instead, a focal point of human interaction throughout history. Kean’s narrative, as a whole, focuses on the many facets of the periodic table including its scientific and nonscientific attributes, providing the reader with a new perspective to this vast array of elements; a social perspective.

The purpose of the Unknown Lab is to practice and implement all that was learned in this microbiology lab this semester about the different test used in identification of an unknown bacteria and to effectively identify an unknown bacterium.

An unknown was given to our group from the professor. The unknown was in nutrient broth, the group received unknown number 3. And the task was to identify the unknown and try to make an educated guess, and identify the unknown #3.

The main component that make up an atom are protons, electrons and neutrons. Protons are positively charged. While electrons are negatively charged. Neutron is not like a proton or an electron. It isn't like proton or an electron because a neutron does not have a charge. They are arranged by the atomic number. The atomic number is the number of protons in the nucleus of an atom and the electrons are arranged in levels. The atomic number is the small number that is at the top left corner of the element in the box. Copper has twenty nine electrons and twenty nine protons. Copper has two isotopes. Which are copper 63 and copper 65. Their compositions of copper 63 and 65 are stable. The abundances of copper 63 is 69.15 percent and copper 65 is

• 2-PS1-1. Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.

All substances are made of tiny particles called atoms. An element is a substance that is made of only one sort of atom. There are about 100 different elements. These are shown in the periodic table, which is a chart with all the elements arranged in a particular way. The horizontal rows in the periodic table are called periods and the vertical columns are called groups. The elements in a group have similar properties to each

Chemistry is by far one of the most important sciences to humans, as it tells how the world around us is composed and tells us about why things act the way they do. Despite this many people find Chemistry to be one of the most confusing and hardest sciences to learn, and one aspect of which that may seem to be the most daunting is the Periodic Table. But in the national bestselling novel The Disappearing Spoon by Sam Kean, he uses a variety of topics to explain the organization, properties and other concepts related to the Periodic Table. In the chapter Elements in Times of War, Kean refers to historical events throughout history to show how the Periodic Table has influenced the way mankind has waged war. Through his use of historical anecdotes,

Most elements on the Periodic Table are important to us. Like, Oxygen, and Nitrogen, or Hydrogen, without those, we couldn’t breathe, have our atmosphere, no water, etc. Although, Silicon and Germanium, two elements that are probably unknown to most people, but without these two, our world would be different.

Now have them all into groups I realize that I could have just used Garfinkel’s invariant procedures as my categories and just organized them based on how I made sense of the cards. My first category could have

The History of the Periodic Table of Elements Dmitri Mendeleev and the early Periodic Table Dmitri Mendeleev was born in Tobolsk, Siberia; on February 7, 1834 .He was the youngest of 14 children born to Maria Dmitrievna Korniliev and Ivan Pavlovitch Mendeleev. His father was director of the local gymnasium. Maria Korniliev's family settled in Tobolsk in the early 1700's and introduced paper- and glass-making to Siberia. Unfortunately, Ivan died when Dmitri was quite young, leaving his wife to support the large family. The death hit them hard economically especially for a large family, which meant that Maria had no other choice but to find work. Maria's family owned a glass factory and they allowed her to take over managing the company so

1743 – 1794 – Antoine Lavoisier established that elements are the fundamental building blocks of chemical substance. He defined an element as ‘a substance that could not be composed into simpler substances. He identified four groups; metals, non-metal, elastic fluids (gas) and earth after examining the physical and chemical properties.
