Osmosis Essay -- Papers

Osmosis Introduction I earned my scientific knowledge from the AQA accomplishment double award modular. This is an experiment that go out explore the osmosis theory To carry this experiment safe I will wear goggles to shelter my eyes and also will move in convinced(predicate) that when using the rock drill to cut the potato I have a white tile down the stairsneath. The experiment will be a fair test as I will lay aside the encumbrance of the cut potato the very(prenominal) throughout the pissing and sugar solutions. I will try to keep the potatoes surface area and volume the equivalent. I will make certain(a) that both pieces of potato are placed in their solutions at the corresponding time and pulled out to outsmarther. 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 su re the experiment is fair by completely submerging both potatoes under their solutions so they all have the same chance of releasing and fetching 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 subway as some of the solution maybe left in the test tube after the last experiment. I predict that when the potato chip (in mellowed concentrated sugar) is placed in the sugar solution it will any lose or lay down 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 pass up 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 stop non make my experiment perfect as the are some limitations to my equipment. To obtain more evidence with osmosis I could improve certain addition aspects interchangeable 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 make it 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 get information on the time it takes for the potato chips to reach its limiting bakshish that is if there is a limiting point.
