Student Activity - Investigating sea water

Activity idea

In this activity, students investigate some of the properties of seawater.

By the end of this activity, students should be able to:

  • discuss that salt dissolves in water
  • explain that dissolved salt does not change the volume of the water
  • discuss the differences in density between freshwater and seawater
  • discuss how freshwater in the form of rain or melting ice reduces the salinity of the saltwater on the surface.
