In this quick activity, learners observe how wind creates ocean currents. By blowing (through straws) on pepper suspended in water, learners will notice how the pepper moves in a clockwise motion, the same basic motion of the currents in the Northern Hemisphere. This resource explains why currents in the Northern Hemisphere behave this way and how currents in the Southern Hemisphere move differently. This resource also includes tips related to rip current safety.
