How can the ocean be colder than 0 degrees C, the temperature at which water freezes? As it turns out, the concentration of the particles (in this case, the ions from the salt) in ocean water lowers the temperature at which the saltwater will freeze. Students will learn how ocean water freezes at a lower temperature than freshwater by
Plan and run a family fun afternoon or evening with several hands-on activities. Students help run the activity stations and share what they have learned about the Polar Regions. A great culminating activity for a unit on the Arctic, Antarctica, or both, and a fun way to involve families in the learning experience.
