Earth Science: Ocean Currents
by Texas Instruments - Simulation Lesson


  • Students will investigate and discover relationships between temperature and salinity as the driving force behind the global conveyor belt.
  • Students will differentiate the differences between surface currents and deep water currents.


  • thermohaline circulation
  • upwelling
  • density
  • oceanic conveyor belt

About the Lesson

In this lesson, students will explore the global oceanic current system. Note: Students should use the TI-Nspire computer software or TI-Nspire™ Apps for iPad® for an optimal experience with this lesson. Some images may be difficult for students to read on the handheld.

As a result, students will:

  • Discover that there is a global oceanic current system that is driven by changes in temperature and salinity.
  • Explain the process of upwelling and what effect it has on the current system.
  • Understand the impact thermal energy from the sun has on the current system.
