What's in that H20? (Quality)

Kids In The Creek

The What’s in that H2O? (Quality) station addresses water quality and its importance for a healthy watershed. Students predict the outcome and then test the creek’s chemical properties to verify their conjectures.

NGSS: HS-LS2-6, HS-LS2-7, HS-LS4-6, HS-LS4-5, HS-ESS2-5, HS-ESS3-1WA SCIENCE Academic Learning Requirements (EALRs): 1.1, 1.2, 1.3,2.1, 2. 3.1

Students will be able to:
  • Describe the hydrologic cycle
  • List the effects of turbidity, pH, temperature, stream dynamics and dissolved oxygen (DO) on the aquatic ecosystem
  • Test the health of the local stream
  • Identify human activities and natural phenomena that impact water quality


  • The connection of water chemistry to stream health
  • Human actions that influence clean water
  • Point and non-point source pollution
  • Ecology

For Teachers:

Classroom Pre-work Activities:
  • Let That Water Breathe and Chill (PDF) – Students identify properties of dissolved oxygen (DO) and temperature, understand the factors that can change a waterway’s DO and temperature, and apply their knowledge by testing the DO and temperature of a local stream to determine its health.
  • The pH7 Scale: Life’s Good Note (PDF) – Students understand the pH scale by testing the pH of common products, and find connections between pH and wildlife.
  • It’s a Dirty Water Thing (PDF) – Students identify potential sources of increased turbidity and predict results of an experiment on sediment levels of a nearby creek.
