Changing Planet: The Case of the Leaky Gyre

In this activity, students model circulation in gyres, explore characteristics of gyres found around the world, and predict the climate impacts of changes to the circulation in these gyres and climate on adjacent land. Gyres, large systems of rotating ocean currents, play an important role in Earth's climate system.

Teaching Tips

Show the video twice, once before doing the activity and once after. Ask students to focus their second watching on the link to climate change.

It will be important to explain (or have learners explain) the difference between gyres and ocean circulation in general.
