Water test experiment.
Team Members: Rolando, Domingo, Diana, Jose S., Jose R., Ana Gabriella, Vanessa, Kimberly, and Ivan.
Coliform Bacteria: are tested by getting sample of the water into a test tube and then dropping a small tablet that changes color depending on the water quality. The different color will tell us the amount of Coliform Bacteria present.
Dissolved Oxygen: getting a sample of water in a test tube and drop two tablets inside the tube, mix, and then wait 5 minutes for the water color to change and then comparing the color to the result sheet. This allows us to measure the percent saturation of water quality.
Biochemical Oxygen Demand: Sample of water is placed inside a test tube and then wrapped in aluminum and kept at room temperature for 5 days, then it is unwrapped and the DO test tabs, cap the test tube and mix the tabs until they dissolve. Compare the color of the test tube on the color chart.
Nitrate: Testing the nitrate amount of water is relatively easy, a water sample is placed inside a test tube; then, a Nitrate Wide Range CTA testab is added and the test tube is slide into a protective sleeve. A cap is placed on the tube and it is mixed for 2 minutes. We wait 5 minutes and the color of the water is compared to that of the color chart.
pH: A test tube is filled with 10 mL of water, and then a Wide Range pH testab is added. A cap is placed on the tube and it is vigoriously mixed with the testabs. Compare the color of the water to that of the color chart.
Phosphate: A test tube is filled with a sample of water. A Phosphorus TesTab is added, then a cap is placed and vigorously mixed. Wait 5 minutes, then compare the colour of the water to the color chart.
Temperature: Thermometer....duh .-.
