Citizen-Sensor Network
Log in to saveStudents build and calibrate simple environmental sensors—like temperature or humidity readers—against a trusted reference, then publish honest, appropriately-qualified local findings. It's real citizen science, caveats and all.

Setup
Print or handwrite the four Citizen-Sensor Network challenge steps and place common paper supplies on one table. Prepare one small sample, dataset, scenario, or recycled-material model drawn directly from the project description; no device, paid tool, room decoration, or purchased kit is required.
Activity
- Read the Citizen-Sensor Network challenge aloud, then set up a simple sensor next to a trusted reference instrument and predict how close the readings will match.
- Use paper, index cards, recycled objects, or facilitator-provided sample data to take parallel readings over several trials and calculate the average difference between the two.
- Run one tabletop trial and discover the sensor drifts or is consistently off, and apply a calibration correction to fix future readings.
- Finish by publish the calibrated local data with a plain-language note on its accuracy and what it can and can't be used to conclude; record the evidence that supports the decision.
Done when: The group completes a defensible Citizen-Sensor Network solution, records at least one test result or comparison, changes one claim or design in response, and supports its final decision with that evidence.
