Grades 6-860-75 minSource: Creative Dad Company

Teams test a local water sample for basic indicators like pH and clarity, then communicate clearly what the results can and cannot tell the community.

Setup

Print or hand-copy the essential prompt for Water-Quality Citizen Lab, then set out only paper, pencils, and the common or recycled items needed for one test. Use a tabletop representation whenever the original version mentions a room, specialized device, or digital tool; the learning comes from the decisions and evidence, not elaborate scenery.

Activity

  1. Look at a local water source and predict what its pH and clarity results will show.
  2. Collect samples and run pH strip and clarity tests, recording results for each site.
  3. Compare results across sites, find one sample gives a surprising or inconsistent reading, and retest to check whether it's a real finding or a testing error.
  4. Write a short public findings report that clearly states what the data does and doesn't prove about water safety.

Done when: The group has completed Water-Quality Citizen Lab when it can write a short public findings report that clearly states what the data does and doesn't prove about water safety and point to the observation, measurement, comparison, or trial that supports its conclusion.
