Paper Towel Experiement Essay Example for Free

Paper Towel Experiement Essay My wife and I go through an enormous amount of paper products. We discuss often which brand works best for the price. Typically, we buy the brand Bounty for our paper towel selection. There is no particular reason why we buy this brand but it seems to be the one we get home with. After reviewing some other literature in regards to the paper towel experiment, I found some different results. According to Consumer Reports (2009), Brawny was the most absorbent of all of the 21 brands that they tested. They found that Brawny held 2  ½ ounces more per square foot on average than the other brands tested. However another consumer, Chelle from Yahoo’s Contributor Network, found that Bounty was the most absorbent paper towel. She tested Scott, Brawny, and Bounty. (2010) Twelve year old Samantha also performed an experiment on paper towels testing four brands: Bounty, Sparkle, Scott, and Western Family. Her hypothesis was that Bounty would be the most absorbent but after her experiment reported that Sparkle absorbing 50 ml of water on average. (2001) Mrs. McKee’s class from Arizona also did a paper towel experiment. They tested their school’s paper towel, Brawny, Bounty, Viva, Scott, and a generic brand. The results from their experiment showed that on average Viva was found to be the most absorbent. (2012) After looking at other research and preforming my literature review, I decided to test four paper towels: Bounty, Brawny, Viva, and Kroger Brand. I decided that I would use 200 ml of water and place each brand of the folded paper towel in the water five different times. I plan to squeeze the water into a beaker and measure how much water was absorbed. I would then take the average to find out which brand of paper towels was more abso rbent. Problem: What paper towel is the most absorbent and leads to the most cost effective? Materials: 1 Glass container labeled with ml to 750 ml 1 small beaker labeled with ml to 150 ml 1 stop watch 1 baby bottle (I only had one glass container with ml labeled) labeled with ml to 260 ml Paper Towels: Bounty, Brawny, Viva, and Kroger Generic Brand (4 brands X 5 sheets) Water 1 Funnel Pen and Paper Prices on the paper towels were how much I paid per roll, but with further investigation I found that the price per square foot was different. Independent Variables: Brand of Paper Towel, price per square foot Dependent Variable: Amount of Water Absorbed, Vivi sheets were much smaller than the other sheets and two sheets were used and cut to the same size as the other sheets – price is still based on per square foot for each paper towel Constants: Amount of water used in each trial, paper towel size, time exposed to the water, type of fluid (water used) I will make sure to use the timer to submerge the paper towels for the same amount of time. I will use the same measuring instruments for each experiment. Hypothesis: Because Bounty’s roll of paper towel cost the most, Bounty will absorb the most milliliters of water per square foot. I came up with this hypothesis because I wanted to show my wife how we could save money by continuing to buy the name brand paper towel. Data Collection Process: Each paper towel was folded four times to create a small square. Each paper towel was emerged into 200 ml of water and left for 20 seconds. Each paper towel was removed from the water allowing drip time of 5 seconds and then the remainder of the water was squeezed to a beaker. The left over water was poured into a baby bottle for measurement in milliliters. At first I was going to use the amount of water that I could squeeze out of the paper towel, but then I realized that some was still left over in the paper towel. To reduce the threats to internal validity, I then decided to subtract the amount of water left over from 200 ml to get an accurate reading of how much water was actually absorbed. Conclusion: Results from my experiment indicate that per square foot, Viva paper towels are the most absorbent. In addition, since Viva’s price per square foot was 4 cents, it would also be the most cost effective. Viva paper towels absorbed on average 8 more milliliters than Bounty and Brawny and 13.4 milliliters more than the generic Kroger brand. At first glance, Bounty looked like the most expensive paper towel with Viva 2nd. However, when you look at price per square foot, the price of Viva and Bounty are the same. Brawny is actually the most expensive per square foot. With this being said, my experiment refuted my hypothesis that Bounty was the most absorbent because it cost the most. Bounty was not the most cost effective because it did not absorb the most and the price per square foot was the same as Viva. Price per square foot indicated that Brawny was in fact the most expensive and it still was not the most absorbent. It is imperative when doing an experiment that the experiment is done with several trials and that the procedure are completed in the same manner. This adds to the validity and reliability of the experiment. To replicate this experiment, you must have the above materials. Choose at least 4 paper towel brands. Fold each paper towel (five trials per towel) four times. Submerge each paper towel individually into 200 milliliters of water for 20 seconds. Remove the paper towel, allowing it to drip for 5 seconds.  Measure how much water is remaining and subtract that number from 200 to see how much water the paper towel absorbed. Record this and continue the step for each of the remaining paper towels. It is recommended to do at least 5 trials per brand of paper towel. When others perform the same experiment, it validates the results from my experiment. References Chelle. (2010)Which Brand of Paper Towels is the Most Absorbent?

Southern Appalachian Cultures: Their Pursuit for Prosperity and the Env

Where there are various regions there are bound to be a variety of people with alternate cultures, beliefs, and ways of life. The cultures found with the Appalachia are unique in their own ways and represent a body of individuals who found their way to such an area. Land that is included within the Southern Appalachia can be best described by Horace Kephart as he does so in his book The Southern Highlander and His Homeland to include: â€Å"the four western counties of Maryland; the Blue Ridge Valley, and Allegheny Ridge counties of Virginia; all of West Virginia; eastern Tennessee; eastern Kentucky; western North Carolina; the four northwestern counties of South Carolina; northern Georgia; and northeastern Alabama.† (22-24) With so much area to be had there are a few prominent cultures and occurrences that need to be discussed. Native Indians, European settlers, Industrialists, and the present economy will be referred to in the process of identifying the cultures within Southern Appalachia. Cultures of the Southern Appalachia that will be discussed will display the lifestyles of many, religion of the areas focused on, and the values individuals held towards the environment. The Cherokee and Shawnee Indians were the more prominent groups found within the Southern Appalachian region. The Cherokee Indians were believed to have come to parts of southern Appalachia during prehistoric times. ("Cherokee Nation-Indian Territory.") They remained in areas such as southwest Virginia, the Carolinas, northern Alabama and Georgia, and the Cumberland Basin of Tennessee and Kentucky. (â€Å"Native American, the Cherokee†) The Cherokee Indians who had settled in Southern Appalachia were an Iroquoian-speaking people, they built their homes from ... ...the factories, loss of timber within the Appalachian forests, and the amount of CO2 releasing into the atmosphere constantly. Presently the damage we have caused to occur upon the environment in the Southern Appalachia is vast and incomprehensible. The greatest environmental challenge facing Southern Appalachia today is the loss of such prized and beautiful â€Å"native forests† of Southern Appalachia. (19) Although much of the timber within the forests has come back after being utilized as lumber, there are extreme consequences for taking away such an important aspect of Appalachian Nature and culture. What’s lost cannot be gained, but we can surely do what little we can to impact of culture and world on matters of the need for preservation of nature, so that the environment may prosper for many years to come. Can you make a sacrifice for your area, for your world?

A Worldview Definition Essay

A worldview is the way you interpret everything that happens around you and the rest of the world. Everyone has some sort of worldview whether it is conscious or subconscious. People have different worldviews and it can be affected by several different factors around them. A Biblical/Christian worldview is â€Å" It’s any ideology, philosophy, theology, movement or religion that provides an overarching approach to understanding God, the world and man’s relations to God and the world,† quoted by David Noebel, author of Understanding the Times. There are five questions that help justify our beliefs in the Christian/Biblical worldview. The first is the Question of Origin, which is how did life begin? In Genesis 1:1 and Psalms 139:13-16 it tells us about the beginning and the reason for all of creation. The second is the Question of Identity. Identity asks the question, who are we? Genesis 1:27 and Jeremiah 1:5 are scriptures that cover the question of Identity. Both tell us that we were made in Gods image and that before we were created we were appointed a prophet to the nations. The Third question is the Question of Meaning/Purpose. This question is asking why we are here. Everyone is born with a purpose for life. John 17:3 states we were put on earth so that we may come to know God. Another scripture is Galatians 5:13-14 which states we were called unto liberty by love to serve one another. The fourth question is the Question of Morality. The Question of Morality asks what is meant by right and wrong or good and bad? Ephesians 2:9-10 states that following Jesus is the best way to have righteous morals. When you follow Jesus, not men you don’t have to worry about what is right or wrong, you know! Acts 5:29 Peter and the Apostles say â€Å"we must obey God rather than men.† The last question is the Question of Destiny. The Question of Destiny asks is there life after death. A scripture that everyone knows that refers to destiny is John 3:16, it says â€Å"should not perish but have everlasting life.† The book of Revelations talks a lot about Destiny, a scripture that goes along with that is Revelation 21:3-5. In those scriptures it tells about how there will be life after death and no more crying or pain. The biblical worldview influences me to always do what Jesus would do and treat people the way I would want to be treated. I have been raised under those sayings and I raise my kids under them also.
