That Sinking Feeling

That Sinking Feeling

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor. Learners observe what happens when they add freshwater and saltwater ice cubes to a fishbowl nearly full of water. A brief explanation included in this resource explains why the ice cubes behave differently and how it relates to the motion of the Great Ocean Conveyor. This resource also explains how thunderstorms relate to air density and how to keep safe during a storm.
