Create a 6 pages page paper that discusses the experiments with the amount of oxygen found in water. The concentration of oxygen in water can be adjusted initially (starting from 6.5mg/L) by changing the duration of the pumping. Once, Oxygen has been pumped into water its concentration can be measured and recorded using an LDO Sensor (hack).

The water in all 10 fish tanks must contain different amounts of Oxygen. Now, fishes of the same species and same age must be introduced into the fish tanks. For accurate results, it is best to select fishes that can survive at a mediocre concentration of Oxygen (6.5 mg/L) and room temperature (25 degrees Celsius). An example of such fishes is Smallmouth bass. The same number of fishes must be introduced into all of the fish tanks. Every day fishes must be given the same brand of fish food and the same amount of food (To ensure this before food is given it can be weighed using digital balance). After a week, the number of fish left alive in the tank can be counted by removing them using a net and counting manually.

The control in this experiment will be a fish tank filled with Smallmouth bass fishes. The number of fishes will be the same as in all other cases. The fish tank will be placed in the lab where the temperature will be 25 degrees Celsius. The temperature will be kept constant using an air conditioner. The fishes will be given the same amount and kind of food as fishes in other tanks. However, the concentration of oxygen dissolved in water will be 0 mg/L. To remove all of the Oxygen from water it can be heated in a saucepan while recording the&nbsp.temperature using a Candy thermometer. When the temperature reaches 286 Fahrenheit Oxygen leaves from the water. By looking at the scatter plot and the correlation coefficient calculated one can conclude that amount of Oxygen dissolved in water is strongly correlated with the number of fish observed in the water. As one variable increases, the other variable is highly likely to increase.
