Knowledge
Base
Gather the
three specialists (meteorologist, landuse planner, and water quality
analyst) for a meeting and discussion prior to collecting data.
Experimental
Design
Agree on
a storm date to investigate based on the dates offered by the teacher.
Ask each specialist to describe the strategies they might use and where
they will find the data they need. Brainstorm as a group to help each
of the specialists. Write down the predictions of the specialists as
to how the major rainfall will affect the lake’s turbidity.
Develop a
strategy for determining how rainstorms have affected turbidity in the
lake in the past. Either write up your strategy as a set of instructions
for another reporter, or actually collect historical data about the affects
of rainstorms on the lake’s turbidity.
Data Collection
When each
of the group members has gathered his/her data, call another meeting.
Data Management
and Analysis
Ask each specialist
to share their information, beginning with the meteorologist, then the
planner, and finally the water quality analyst.
Interpretation
of Results
As a whole
group answer the following questions:
- How
did the major rainfall affect the lake’s turbidity
values?
- Explain why some watershed characteristics may have significantly affected
the impacts of the rainfall on lake turbidity values.
- Explain why some landuse activities may have significantly affected the impacts
of the rainfall on lake turbidity values.
Reporting
Results
The reporter
has the responsibility to share this information with the rest of the
class.
