Description:

These two hands-on labs are about the role of temperature and salinity in governing the density of seawater, a major factor controlling the ocean's vertical movements and layered circulation. In the first activity students work in groups to determine the density of tap water and of tap water with salt, then compare the densities. The second activity investigates the role of temperature and salinity in determining seawater density. Students use a Temperature-Salinity (T-S) Diagram to examine the effect of mixing on density. A list of key concepts, essential questions, common preconceptions and more is included. These are part of the Aquarius Hands-on Laboratory Activities.
