How Ocean Currents Work - And 24 Other Lessons About Oceans

How Do Ocean Currents Work? is a TED-Ed lesson that makes a fantastic addition to TED-Ed's list of lessons about oceans. The list now has 25 lessons covering a range of ocean-related topics including how waves are formed, the depths of oceans, and lessons about marine life.

In How Do Ocean Currents Work? viewers learn about the forces influencing surface and deep ocean currents. The lesson is told through the story of 28,000 rubber ducks drifting around the world.

I've watched this lesson a few times. The last time that I watched it I realized that the clay model featured in the video could be replicated in a fish tank or large dish pan. Having students make and modify models like the one in the video could be a good way for them to see and experiment with forces that influence the flow of water.

If you have students who watch Deadliest Catch, the following three videos could help them understand how tides work.

I've also embedded the video below.
