In the analysis, the hypothesis was that pennies made before 1982 were made out of a different substance than the pennies made after 1982. The hypothesis turned out to be true. The pre 1982 pennies were made out of copper which has a density of 8.6 g/mL and the post 1982 pennies are made out of zinc which has a density of 7.14 g/mL. So it can concur that mass for pennies made before 1982 are higher than pennies made after 1982. Some errors were when calculating. The densities for the pennies and making the graphs. When making the graphs, it can be suspected that each graph is wrong could be wrong due to not adding enough data points or misplaced points. For the data tables , it can also be suspected that the density for each data table could
For her book, Nickel and Dimed: On (Not) Getting by in America, Barbara Ehrenreich, a middle-aged female investigative journalist, assumed the undercover position of a newly divorced housewife returning to work after several years of unemployment. The premise for Ehrenreich to go undercover in this way was due to her belief that a single mother returning to work after years of being on welfare would have a difficult time providing for her family on a low or minimum wage. Her cover story was the closest she could get to that of a welfare mother since she had no children and was not on welfare. During the time she developed the idea for the book, “roughly four million women about to be booted into the labor market by welfare reform” were going to have to survive on a $6 or $7 an hour wage; the wage of the inexperienced and uneducated. This paper will discuss Ehrenreich's approach to the research, her discoveries, and the economic assumptions we can make based on the information presented in her book.
Barbara Ehrenreich’s book “Nickle and Dimed” she explored a life as having a low wage earning by working several jobs in numerous of different places as she tempted to live off the wage she earned. Even though she had a doctorate in science she is known as a journalist and as well as muckraker. In the novel she states her journey on how she pondered how someone unskilled, uneducated, and untrained workers can survive with the minimum wage incomes. Barbara gave us real life experiences of her personal life as she had witnessed firsthand as her loved ones struggled living minimum wage jobs to provide enough utilities for her family.
Have a good look at the penny, what do you see? You probably see nothing but a copper coated circular poor valued cent. Little does everyone know pennies have been around longer than before their grandparents, even their great-grandparents! Matter of fact, it was around so long ago that Abraham Lincoln’s face was not the first design on the penny. I ask that you take the time to consider the American penny’s worth. Without the people’s belief in its value, the penny will be abolished. I see people every day throwing away a penny rather than to put it in their pocket and save it for future uses. Yes a penny is "outdated, almost worthless, bothersome and wasteful" (Safire) piece of junk, but it's has an economic, cultural, and historical significance to the United States of America. The problem is that nobody pays attention to that, and that gives pennies the image of no value. Three good solutions to show the pennies worth include: tolls and vending machines accepting the coin, more charities to keep their penny drives, and historical evidence of what the penny mean to America so that it can be passed on to the future generations.
The penny is so close to worthless that there is a major debate on whether the penny should be kept in circulation. Keeping the penny in circulation would be mostly for those traditionalists who see this coin as history and luck. Many are working very hard to keep that piece of history from meeting its retirement. ALTHOUGH THE PENNY HAS BEEN AROUND THROUGH AN ABUNDANCE OF GENERATIONS; DEPLETING THE NATION OF THIS COIN WOULD BRING LESS HASSLE AND MORE BENEFIT.
Poverty and low wages have been a problem ever since money became the only thing that people began to care about. In Nickel and Dimed: On (Not) Getting By in America by Barbara Ehrenreich, she presents the question, “How does anyone live on the wages available to the unskilled?” This question is what started her experiment of living like a low wage worker in America. Ehrenreich ends up going to Key West, Portland, and Minneapolis to see how low wage work was dealt with in different states. With this experiment she developed her main argument which was that people working at low wages can’t live life in comfort because of how little they make monthly and that the economic system is to blame.
Nickel and Dimed is a book about the author’s trip into the working poor world. Her profession was as a professor in biology. She noticed similar traits of her studies throughout the years, their struggle with being working poor. This struggled she saw preempted her to create a social experiment that is about how to live as a unskilled, working poor person in America. Instead of experimenting on others she took upon herself to be the one who drives into this unknown world to her. This assignment she given herself wasn’t an easy task and Ehrenreich experiences many conflicting emotions about what she will take on. Before she drives into her social experiment, she create some basic rules she must live by: She has to take the highest pay job offered and do her best to keep it, no relaying on past skills, she has to find the most affordable living conditions in the area she was in. These rules were not easily kept during the experiment and eventual she broke them all at one point or another. She also set some reasonable limits that protect her from going hungry or homeless. There was a couple times throughout the experiment that she broke her
Pennies have always been respected for having played a big role in american history but does the penny actually deserve to be held in such high regard if it's just collecting dust under the couch. Since 1857, the penny was used and changed throughout the years but it might be a better idea to get rid of the penny because of its expensive production costs and its effect on the economy.
While the penny is only worth one cent what is it worth to millions of Americans who had relatives fighting in the civil war, or that were slaves in that time period? Pennies mean more than just currency it has a very important value in history. Yes the penny may be the lowest type of currency here in the U.S, but its sentimental value means more to Americans than the value to businesses.
The hypothesis on whether the mass of the Gummy Bear would increase or decrease was accepted. The data collected during the lab supports my hypothesis because the experimental Gummy Bear's mass for Day 1 was 2.7g when placed on the balance. Then in Day 2, the mass increased to 6.0g. The change in the mass of the Gummy Bear's were 3.3g. The Control Bear's mass on Day One was the same as the experimental Bear's, 2.7g. On Day Two, after being stored in a refrigerator for 24 hours, the mass was still the same staying at 2.7g. Some options for future projects like this are finding the increase or decrease in the density. Or another option is to find the increase or decrease in the measurements of the Gummy
Using the previously calculated Kf, the molar masses of unknown substances A, C, and D were able to be calculated. However, given that the original Kf was slightly larger than the theoretical value, the molar
The penny has been in America for centuries, it's a sentimental object for Americans everywhere. However many have debated on whether or not it should be eliminated or continue being made. The penny should be preserved because it is apart of American culture, given to charity, and keeps items cheap.
Various sizes of potato cores may cause a change in the data because different sizes may be able to absorb more or less salt concentrated water, resulting in an inaccurate mass measurement. A solution to this could be a different method to cut the potatoes so that they’re equally sized for more accurate data, possibly by using a vegetable slicer or something of the sort. Another thing that could have affected the data is the plastic wrap. We covered our cups with plastic wrap, but it didn’t stick very well to the cups. This made it so that our cups were not securely covered, and the amount of air that was able to leak into the cups over the 24 hours may have affected the results. Perhaps we could’ve used stickier plastic wrap, or maybe used rubber bands as well to secure the plastic wrap
What was the most significant and very unique from the rest of the data was the patrol behavior type. In both graphs we could see that patrol was higher for Tank B instead of Tank A, which was the norm. Some of the patterns found noticeable in both graphs was how Tank A had loftier numeric values than Tank B. Patterns like this helped construct a better analysis and assumptions to make a valid conclusion. Reasoning behind the the trends could be related to the effect lead could have caused on the brain. Since we know lead is a substance that has no use in a mammal's
1984, a novel by George Orwell, represents a dystopian society in which the people of Oceania are surveilled by the government almost all the time and have no freedoms. Today, citizens of the United States and other countries are watched in a similar way. Though different technological and personal ways of keeping watch on society than 1984, today’s government is also able to monitor most aspects of the people’s life. 1984 might be a dystopian society, but today’s condition seems to be moving towards that controlling state, where the citizens are surveilled by the government at all times.
Our hypothesis for this lab was that the limestone will add mass because it is a sedimentary rock, and weathering and erosion break down a rock. Our data refute our hypothesis because we said it will gain mass when the limestone lost mass. The limestones Initial mass was 3.67, and after we put it in the oven the mass went down too 2.81. The mass went down by 0.86. Also, the graph above shows our data. The red line of the graph was the change in mass after we put it in the oven, and the blue line is the Initial mass. The red line doesn't move that much. After we put the rocks in the oven only one changed in mass. The Limestone changed 0.86 in mass, Quartzite changed 0.00 in mass, and Obsidian changed 0.00 in mass. By that data the oven did not really change the difference in mass. The blue line is our initial mass. Limestone was 3.87, Quartzite was 67.51, and Obsidian was 10.63. In the graph it shows the blue line going up. Our initial mass goes up, but our final mass stayed the same besides the limestone changed by 0.86. In the graph there were two trends. One goes up, and the other one basically stayed the same. The initial mass had a bigger impact because we used 3 rocks, and they were different masses. For the final mass the trend wasn’t that good because two of the final masses stay the same at zero, and the one that changed in mass was only a 0.86
