02.03 water quality virtual lab worksheet


Analysis:
Review your data carefully to make inferences about pollution. Answer these questions in complete sentences.
1. Identify the pollution type that caused the most change in stream diversity.
Which pollution type caused the greatest change in pH? Did this pollution make the water more acidic or more
basic?
3. What effect did thermal pollution have on water hardness? Explain why this occurred.
Which pollution type shows evidence of eutrophication. Explain your reasoning.
5. Which pollution type resulted in the most hypoxic waters? Support this with evidence from your data.
6. Which aquatic species were not able to tolerate any of the pollution types in the stream?
Making Connections:
Use the lesson content and the results of your lab activity to answer the questions below in complete sentences.
1. Were the pollution sources in the water quality lab point sources or nonpoint sources? Explain your reasoning.
2. Using what you know about macroinvertebrates, explain why some species increased while others decreased.
3. Read both questions below. Answer either one of your choice.
a. What effects, besides death, would you expect to see in aquatic species exposed to thermal pollution?
b. Pick one of the pollution types in the simulation. How would this pollutant affect human health?
4. Describe how a pollutant dissolved in surface water can enter an aquifer. Be sure to include the water cycle's and groundwater's roles in this pollution.
