This data is a picture of the Triplett Creek ecosystem over time. What are the relationships between the different
variables? How have abiotic factors like rainfall or temperature impacted the ecosystem? You are going to analyze some of
these patterns. To do this, you will choose one pair of variables from each section below to complete.
Relationship Variables

Water temperature and dissolved oxygen (double line graph – relationship)

Rainfall and conductivity (single line graph – relationship)

Compare water temperature and conductivity (double line graph – relationship)
Effect on Ecosystem Variables

D.O. and bio index (double line graph – effect on ecosystem)

Rainfall and bio index (single line graph - effect on ecosystem)
You will start your analysis with one of the “relationship variables”. To begin, construct a line or double line graph (whichever
is specified). Once your graph is complete, look at the pattern/relationship between the variables over time (year to year)
then use your prior knowledge and resources to discuss your findings.
Do not begin the second writing activity until you have been given further instructions. This second piece will have a
different due date. For your second analysis, you will choose one of the “Effects on Ecosystem Variables”. Begin with the
graph that is specified. Once your graph is complete, you will use your graph, your prior knowledge, and resources to write
about your findings.
