Jessica WBiology 160Kirsten McDadeLaboratory 3 Write-Up1.One of the lab objectives is “Study the effect of temperature on the maximum amount ofdissolved oxygen in water samples.” When we took various data samples of temperaturecompared with amount of dissolved oxygen, we found a correlation between lowertemperatures and higher dissolved oxygen levels. This was our conclusion, that lower watermeant higher dissolved oxygen.2.First we poured 500 milliliters of hot water into a jar. We shook the jar 20 times and then put thewater in a beaker. We put the temperature and oxygen probes in the beaker and recorded thedata. Then we poured 80 milliliters of ice into the water, and repeated what we did with the firstsample.3.Temperature (⁰C)Dissolved Oxygen (mg/L)23.8718.16.913.78.710.89.69.19.97.110.330.69.922.810.4
