Investigating the Effect of Salinity on the Density and Stability of Water
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Salinity
Learners take a provided ocean Trivia Quiz in order to start a discussion of the ocean. They then perform an experiment on how the amount of salt in the ocean affects it and varies from ocean to ocean.
