Step 2: Test Your Water
Now it’s time for students to become community scientists. Testing a local waterway helps students connect science to place — and contributes real data to a global movement.
- Collect water samples from a local site
- Test key water quality indicators
- Record and interpret results
- Discuss what the data reveals about ecosystem health
What to Test
Anyone can participate in the EarthEcho Water Challenge, testing surface water quality for key indicators like temperature, pH, dissolved oxygen, and turbidity.
EarthEcho's global database also allows you to submit dozens of additional measurements, including macroinvertebrate counts, giving students flexibility to explore water health in their own way, using any equipment they have access to.
Want to dive deeper into macroinvertebrates? Check out MacroBlitz, a great resource for identifying and counting aquatic insects and other critters in your local waterway.
