Begin playing and click the pond in the mid-Atlantic region.

1

Explain why the pond is not a good location to sample water from.

1

Would pollutants in runoff be an example of point source or nonpoint source pollution?

1

Explain your answer from #12

1

Scientists are interested in measuring the effect of pollution on the water quality of a stream. They will use observations of various bottom-dwelling insects, or macroinvertebrates, collected in the stream as indicators of the physical, chemical, and biological conditions within the stream. Which of the following best describes why macroinvertebrate sampling can be used to assess the overall health of a stream?

Now click on the mid-Atlantic stream.

1

Where is the best place to sample from in the stream?

1

Explain why you think this is the best place to sample in the stream.

1

What do you use to measure a sample of water's physical properties?

1

Identify three parameters you are measuring in regards to a sample of water's physical properties.

1

How deep does the probe need to be in the water (click on the probe to submerge it)?

1

After you take three samples, record your average measurements of the sample of water's physical properties in the data table.

1

Did average temperature, turbidity, and pH vary significantly between the different locations?
