Adding salt to water makes it a better conductor. In general, electrical conductivity increases with increasing distance from the top of the watershed. Also, evaporation can concentrate the amount of salt in water because the salt does not evaporate with the water. Road salt inevitably winds up in surface water. This activity shows the students how much salt is in the different types of water we have at GetWET.
