Lesson 3: Water Pollution Dilution Solution

Do the effects of water pollution in a harbor affect the ocean water farther away? How does the pollution around ships compare to that found in the open water? Grab your controller and guide your Unmanned Security Vehicles to the open waters.

Doing the science

1. You must have completed Lesson 1: Water Pollution Source to conduct this lesson.
2. Start the Unmanned Security Vehicle Simulation by clicking on the "Sim" tab.
3. Write the name of the ship or water outflow that you determined was the source of pollutant in Lesson 1 in the first row of Table 1 next to "Ship or Water Outflow Pollution Source."
4. Click the red ball in the "Controller" box. Dragging the red ball will control the direction of the Unmanned Security Vehicle (USV).
5. Use the controller to move the USV right next to the ship or water outflow that was the source of pollution.
6. Click "Sample" to create a sample of the water in that position.
7. Now move the USV a short distance away from the pollution source and repeat step 6.
8. Move the USV a greater distance away from the pollution source and repeat step 6.
9. Repeat step 8 so you now have a total of four data points, each farther from the source than the previous point.
10. Click on "Temp" under the "Results" panel and record the temperature into Table 1 below.
11. Click on each category (like oil, radiation, etc.) under "Results" and record the data into the table.
