Activity Summary

In this activity, students analyze graphs of data from Sykes Creek, a stream in Florida that was the site of a fish kill in 2016 (the fish kill isn’t revealed to students until the end). After looking at the graphs of algae and dissolved oxygen, they read about the connection between algae, dissolved oxygen, and decomposers. Finally, they use what they have learned from the graphs and the reading to explain what caused the fish kill.
