Water makes up about 71% of the Earth’s surface. The human body is made up of 60% of water. This means that water can be found anywhere. Humans use water to shower and as a beverage. Though we use water for almost everything, it does not mean that it is clean. Water can have many microorganisms and bacteria found in it. We will be analyzing and testing samples of water. The main purpose of this report is to compare the water samples from Amazon Lake and the Fairchild Lake based on their turbidity level and dissolved oxygen level. When done we will be able to determine the differences between the lakes. Water quality is a measure of the condition of water relative to the requirements of one or more biotic species and or to any human …show more content…
We used the new turbidity machine to figure out the turbidity of the lakes. To calibrate it we had to put distilled water, so it would reset to zero. We had to wait about seven minutes for it to reset. Afterwards we put the the Amazon Lake sample in and waited for seven minutes to get the results. When it was done we wrote down the result the machine provided. Then, we through out that sample and filled the vail with the Fairchild water sample. We did the same procedure as before; we waited seven minutes and then recorded the result. After being done with recording the turbidity results, we had to test for dissolved oxygen. For this we used the Dissolved Oxygen Probe. To calibrate the Dissolved Oxygen Probe, Mr. Ruiz had to put the probe into the distilled water and we waited for seven minutes. Later, we put the probe in the Amazon Lake water and did the procedure of one group member holding the probe for it not to hit the bottom of the beaker, as it can mess up the results because of the electrodes found in it. After waiting seven minutes, we quickly wrote down the result and repeated the same process with the Fairchild water …show more content…
NTU stands for Nephelometric Turbidity Unit. This means that it measures how much light can be seen through the water. The turbidity for the Fairchild Lake was higher than the one for the Amazon Lake at Zoo Miami. This is understandable, considering that Fairchild deals more with plants. A lot of the soil from the plant could have been washed away into the lake and not let the sediments and particles settle at the bottom. Another thing is, that in the lake found in the Amazon of Zoo Miami, people are able to see Koi fish. Koi fish cause a lot of movement not letting the sediments and particles to settle at the bottom. When measuring dissolved oxygen (D.O), scientists use the measure, mg/L. Though the level of turbidity was higher in the Fairchild Lake, the level of dissolved oxygen is higher in the Amazon Lake. The Fairchild Lake most likely had less movement of the water than in the Amazon Lake, that is filled with Koi fish. This would explain as to why the level of dissolved oxygen is lower in the Fairchild
