    A Note to Teachers
    What is this activity? A Note to Students

    "Troubled Waters" is an authentic task dealing with different factors and how they change certain parameters in a river. Several of these parameters are dissolved oxygen, pH, nitrates, and fecal coliform bacteria.


    Students will be using the modeling tool STELLA. Students will run a river model, interpret graphs, and adjust a variable such as wind speed and sewage load to determine the effects on Dissolved oxygen levels.
