Build and Test a Conductivity Probe with Arduino

Type of Resource



From TeachEngineering - Student groups construct simple conductivity probes and then integrate them into two different circuits to test the probe behavior in solutions of varying conductivity (salt water, sugar water, distilled water, tap water). The activity culminates with student-designed experiments that utilize the constructed probes. The focus is to introduce students to the fabrication of the probe and expose them to two different ways to integrate the probe to obtain qualitative and quan

Performance Expectations

HS-PS1-3   Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.

HS-ETS1-2   Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
