What Role Does Salt Play in the Basic Properties of Water?
A defining characteristic of ocean water is its relatively high concentration of dissolved salts or salinity. These concept
maps, activities and videos focus on relationships between salt and water, including water properties, phases, heat capacity
and the hydrologic cycle. These resources will help to organize information into meaningful patterns that students can use for
future problem solving. The interlinked concept maps are provided to illustrate that salinity-related processes do not exist
in isolation: each depends on its relationships to others for broader meaning (i.e., square concepts provide direct links to
other maps in the series).Featured Concept Map: Properties of Water
