Density and Stability Lab:  This activity will help students
to understand how salinity affects the density of water. In addition, students
will better understand how pure and salt water systems work together. With
a little extra guidance, they will be able to apply this knowledge to the
open ocean and to the Navy's uses of submarine buoyancy.
 Liquid Rainbow: Students are challenged to layer five liquids of different density in a drinking straw. It's
A Matter of Density: A hand-on discovery lesson introducing density.
