Students analyze surface air temperature anomalies to identify change with respect to different latitudes across the world.

Students will analyze a line graph that shows how the surface temperature and air temperature values change over the course of 24 hours.

In this activity, students make a claim about the cause of ocean currents and then develop a model to explain the role of temperature and density in deep ocean currents.  This lesson is modified from "Visit to an Ocean Planet" Caltech and NASA/Jet Propulsion Laboratory.
