Osmosis Essay -- Papers

Osmosis Introduction I obtained my scientific knowledge from the "AQA science: double award modular." This is an experiment that will explore the osmosis theory To make this experiment safe I will wear goggles to protect my eyes and also will make sure that when using the borer to cut the potato I have a white tile underneath. The experiment will be a fair test as I will keep the weight of the cut potato the same throughout the water and sugar solutions. I will try to keep the potatoes surface area and volume the same. I will make sure that both pieces of potato are placed in their solutions at the same time and pulled out together. I will make the weight of the potatoes the same by using the top pan balance and keeping the weight roughly the same through out the different potatoes. I will measure the potatoes to 2 decimal places (g). I will make sure the experiment is fair by completely submerging both potatoes under their solutions so they all have the same chance of releasing and taking in water or sugar solution. When repeating the experiment to get a more accurate result I will make sure I use the same controls. I will be sure to have a different test tube as some of the solution maybe left in the test tube after the last experiment. I predict that when the potato chip (in high concentrated sugar) is placed in the sugar solution it will either lose or gain in weight. As the potato is in a concentration that is higher in water than itself it will gain weight and when a potato is in a concentration that is lower in water than itself will lose weight. This is due to osmosis. Osmosis is the diffusion of water from a... ...also have an assistant to help me remove and place the potatoes in the solutions so that they all had equal amounts of time in their solutions. I can not make my experiment perfect as the are some limitations to my equipment. To obtain more evidence with osmosis I could improve certain addition aspects like the amount of solution in the test tubes, so that you could get results on whether the amount of solution affects the amount of osmosing a potato chip can do. Some potatoes could have more sugar in than others, so to extend my investigation I could produce results on which potatoes have more protein in. I could add additional information about the time it takes for osmosis. I could retrieve information on the time it takes for the potato chips to reach its limiting point that is if there is a limiting point.

Foreshadowing In “Of Mice and Men” by John Steinbeck Essay

John Steinbeck uses foreshadowing through out the story of â€Å"Of Mice and Men† to prepare the reader for the final scene. Foreshadowing is the composition of layered hints or clues about what may happen in the future of the story. Early in the story, these lines or events suggest a wide range of possibilities to the audience. But as the story progresses, the range narrows. In order for the impact of foreshadowing to be effective, the audience has to be both surprised by the climax of the story and find it logical. The logic comes from foreshadowing. Steinbeck uses foreshadowing in the course of â€Å"Of Mice and Men† by pulling together past events in the story, to build to the ending impact and overall importance and effect of the final scene. In the first chapters, it is apparent that Lennie is a simple minded man who likes to pet things that are soft and delicate. George and Lennie are traveling through to the farm for work. They had to escape from the town they were previously at because Lennie had an incident with one of the women in the town. He was a rather large, frightening fellow. He went up to a young women because the beauty of her dressed marveled him. Just as he did with mice, he insisted on touching it. That is all. Because of her frightened screams, he grabbed onto the dress and did not let go out of fear and panic. This led him into much trouble and the townspeople to go after him. George took Lennie and they escaped the town. This is foreshadowing to the ending scene because once again, Lennie just had to have a touch and once again, led him to trouble that even George could not fix. When Carlson insisted on killing Candy’s old worn dog friend, it was foreshadowing to the final scene in which all of the men insisted on searching and killing Lennie. Although Candy deep down knew that his dog was beyond his years and was suffering day to day, it was hard for him to accept it and let go. His dog was his only true friend. The same is true about Lennie and George’s relationship. Although George knows what Lennie has done is wrong, and that if he were to remain around or alive that he would just suffer more with his conscience and the other men searching for him. Candy feels that he should have been the one to take his best friend out of the world in which he played such a great part in. This is foreshadowing to the  time that George is faced with the same decision. George feels it is his job and right to have the choice to be the one to kill Lennie. George kills him quickly and painlessly, without the suffering that the other men wished to cast upon hi m. Steinbeck uses foreshadowing in the course of â€Å"Of Mice and Men† by pulling together past events in the story, to build to the ending impact and overall importance and effect of the final scene. At the beginning, Lennie gets in the middle of mass confusion when he approaches a woman and tries to stroke her soft dress. George then collected Lennie and they both escaped town. This is foreshadowing to the ending scene because once again, Lennie just had to have a touch and once again, led him to trouble that even George could not fix. Another example of foreshadowing is when Carlson kills Candy’s dog who was past his time. Candy said he should have been the one to do it. This foreshadows George’s decision with Lennie. Although he knows he needs to do it, it is just to painful.

Death, Morality, And The Afterlife - 919 Words

The idea the death, morality, and the afterlife have gradually changed through history. Death has an unavoidable and unpredictable nature. The conceptualization of death and what happens to a person when they die is perplexing to understand. Humans tend to fear the things in which they cannot begin to explain. No one person exactly knows for sure what to expect once they leave this world. So, we have established religion and science in an attempt to allow us to wrap our heads around this idea. Eventually, all living things must come to an end. This notion that death will occur has been the most constant perception throughout time. According to The Father of Psychology Sigmund Freud suggested, â€Å"Death is inevitable, yet inconceivable. Even though there’s no way of articulating it, you know it’s going to happen.† Our mortality can be defined synonymously with our humanity. We constantly strive to find the purpose of our existence based on the choices we make an d how we live it. Since there is no way to predict our deaths we must explore all opportunities that life has to offer, but show a form of restraint like the Sumerians believed. One of the first recorded civilizations was discovered in Uruk. During this time two significant names that were mentioned in previous lessons were Gilgamesh and Enkidu.
