Water, whether fresh or salty, serves as one of the best electrical conductors on the planet. Does salt effect its conductivity? In this activity, learners will explore the effects of salts in the water, as well as the effects of other parameters on the conductivity of water. Learners will use real-time data from buoys around the coastal U.S. in this exploration.
