Decimal

with this practice with a known density, our density calculations were far off from the densities of the identified elements. This could have been due to using a graduated cylinder to measure volume because it causes variability when determining decimal places. Even without a correct density, we determined the Group 1 element, labeled A2, to be sodium based on its high reactivity in water and its appearance. We determined the Group 2…

math, particularly trigonometry. A carpenter on site, needs to determine how big to make a cut, or how to solve a problem they may have. They need to be able to add, subtract, multiply, divide a multitude of whole numbers, as well as fractions and decimals. Carpenters also need to know how to come up with…

It seems to happen all the time, and people always seem to be fixing it, but why is hazing still a problem? The definition of Hazing is the imposition of humiliating physical training and initiation tasks that are part of a program. Hazing seems to happen mainly in the Greek life during the week long process of pledging. This can be caused by excessive drinking, dangerous activities, irresponsibility, etc. Hazing has been brought into the public eye many times, but it doesn’t seem to be…

By adding Hydrochloric acid into solid Magnesium, in Data table #2, when Hydrochloric acid was first been added to solid Magnesium, the ribbon immediately start to bubble and producing fumes at the same time with a burning sound. Magnesium start to turn into a white liquid form. After the bubble start to disappear, more Hydrochloric acid was added, and the reactions repeats. Until none of the shiny silver Magnesium ribbon can be seen, and there is no more bubble, the reaction is over. After…

The book, Library: An Unquiet History, by Mathew Battles, discusses the history of libraries and books and how they have shaped the way, we as people have advanced throughout history. The destruction of books throughout history has been pretty common. The dozens of political brawls and genocides in history of mankind have proved that books are a sign of freedom that isn't seen highly by war mongering generals and power hungry dictators. Yet, Battles repeatedly explains that although history…

Demitri Mendeleeve was a Russian chemist who invented the first periodic table in 1869. The periodic table he made was very different from the modern day periodic table we know today. Henry Moseley updated Mendeleev's version of the periodic table in 1915. This is more like the periodic table that we know and use today. The only difference is that there has been many more elements added. Mendeleeve also had predicted a lot of the characteristics and properties of elements that would fill up…

Before I start to tell you this story, I would like to ask something of you. I don’t know if this paper is worthy of being put up on the board, but I would like to ask for it to not be put up on the board. The person in this story does not know- and I would like to keep it that way. I will be changing the names and leaving out information but I still fear that they might put two and two together if they read it. I was in lower school and my teacher was Ms. Smith. I enjoyed the class, and…

The planets rotate around the sun, and Olivia, Auggie’s sister, is one of Auggie’s planets. R.J. Palacio wrote the inspiring novel titled Wonder which demonstrates the behavior of human beings when confronted with Auggie, who possesses a face abnormality from birth. The deformity creates numerous responses of disgust from public encounters, but Olivia displays unconditional admiration towards her younger brother. Even though Olivia becomes distant during her first year of high school, she…

Nelson Mandela once said that he believes “The death sentence is a barbaric act… It is the reflection of the animal instinct still in human beings.” Nelson Mandela was the president of South Africa from 1994 to 1999 and he always argued that the death penalty was an animal act. The death sentence was a large part of the play Twelve Angry Men, written by Reginald Rose. Although the jury room has been seen as one single aspect of a courtroom, there are really four elements that make the jury room.…

Objective: The lab we completed today was “Equilibrium of coplanar forces”. The objectives of todays lab was to study the composition and equilibrium as well as study the rectangular resolution and equilibrium of coplanar forces. Principles being examined: The main principle being examined in this experiment is the fact that several forces that line on a plane and pass through the same point can be balanced by a single force that is passing through the same point. We do this by finding the…
