Effect of Acid on the Swimming Speed of Paramecium tetraurelia
Hypothesis and justification: Paramecium tetraurelia is a large eukaryotic unicellular organism that feeds on bacterias and can be easily culture in a laboratory. This cell is covered with cilia, which are hairs on the surface, that allows the cell to move smoothly throughout the environment in which it is located, to look for food and to avoid any negative outcome. The swimming behavior of the Paramecium can be affected by environmental factors. As a class, we investigated several of this environmental factors such as global warming, pollution, and waste. As well as the effect of acid and base on these cells. We found that there was an experiment made by Mahmood Saboungi in which he investigated the survival rate of Paramecium on acid and base, vinegar as acid and baking soda as base. He discovered that the cells did not survive at a low level of pH as well as at a high level of pH in which the cells became to slow down and started dying. After listening to each other proposal, we determined that we were going to develop an experiment to find the effect of two different levels of acid on the swimming speed of Paramecium. So we came up with the hypothesis that the swimming speed of the Paramecium will be significantly faster at a pH level of 5 than at a pH level of 6.8. The null hypothesis is that the swimming speed of the Paramecium will not be affected by the level of acid.
