To Be Salty Sea Ice Or Not To Be Salty Sea Ice - An Introduction to Sea Ice at the Polar Regions
This activity helps students to understand the many roles that polar sea ice plays in the systems that maintain our planet, by first helping them to understand the process of the formation of ice in oceanic regimes. Students will use an inquiry based lab experience relating salt content to the ability of water to freeze in order to begin this study. Specifically, they will design an experiment to determine if salt keeps seawater from freezing.
