Benthic Macroinvertebrate STEM resources.
BMIs are indicators of water quality health. Plus they move around a lot! BMI are interesting for all grade levels.

Conductivity STEM resources.
Conductivity, or the amount of ions (aka salts) in the water, are a great parameter for all grades, including later elementary.
Here is the Conductivity Student Page
Dissolved Oxygen STEM resources.
DO is a key parameter for life in the river. DO is a fabulous area of study for high school students.
Here is the Dissolved Oxygen Student Page
pH STEM resources.
pH is a great parameter for middle and high school students.
Here is the pH Student Page
Stream Discharge STEM resources.
Students measure stream speed across a transect, then calculate discharge. Some students enter the stream. Best for secondary students.
Here is the Stream Discharge Student Page
Stream Erosion STEM resources.
Erosion creates sediment and nutrient loading in our river. This parameter is great for all ages, and can be used to connect human land use with all the other parameters.

Stream Speed STEM resources.
Stream speed is a fun parameter and can be utilized for middle school math too.
Here is the Stream Speed Student Page
Stream Temperature STEM resources.
Stream temperature is an indicator of many factors and impacts dissolved oxygen. This parameter is good for all ages.
Here is the Stream Temperature Student Page
Turbidity STEM resources.
Turbidity, or the amount of stuff in the water, is a great parameter for all ages and connects erosion and land use to dissolved oxygen.
Here is the Turbidity Student Page
