Water Quality

This video shows water throughout Chichaqua Bottoms Greenbelt and discusses the quality of the Greenbelt’s water compared to other places in the state.

Chichaqua Bottoms Greenbelt - Maxwell, IA

Possible Guiding, Compelling and/or Anchoring Questions

  • Why is Chichaqua’s water quality higher than the water quality of some other places?
  • How can water be “clean” even though it sometimes looks dirty?
  • How can we measure and improve water quality?

Classroom Suggestions

Students could:

  • Video conference with or meet a water quality engineer to find out how water quality is tested and what it means for water to be of “good” quality.
  • Test and analyze water from different sources in their area.
  • Research how wetlands improve water quality.
  • Compare and contrast the water filtration that occurs in wetlands to how water treatment plants and small-scale filtration solutions (personal water filtration devices, solar distillation, etc.) work.
  • Define a particular problem of water quality in their community or the world, including criteria and constraints.
  • Choose between different solutions for that problem and justify their decision.
