Students will understand the following:
1.All the oceans on Earth are really one "world ocean."2.Warmer water from the oceans around the equator rises to the top, while colder water from the oceans around the poles sinks to the bottom.3.Ocean currents are caused by the rising and sinking of warmer and colder water.4.Ocean currents affect weather and life all over the globe.
Materials

For the whole class, you will need a globe, research materials, a computer with Internet access, and access to a freezer. Each group will need the following materials:
•Pitcher or container•Tap water•Food dye (dark color)•Ice cube tray•Glass baking dish
Procedures

1.Divide your class into groups, and have each group prepare for the activity by mixing food dye into water, pouring the water into an ice cube tray, and freezing it.2.Display a globe and have your students observe that all the oceans on Earth are connected to form one "world ocean." Ask them where they think the water would be warmer—near the equator or near the poles. Then tell students that they are going to perform an experiment to demonstrate how the colder waters nearer the poles and the warmer waters nearer the equator mix together and move to create ocean currents.3.The students in each group should fill a clear baking dish with warm tap water to represent the warm water near the equator.4.Instruct students to place one ice cube at each end of the baking dish, representing the cold water near the poles. Invite them to predict what will happen as the ice cubes melt.5.Students will observe that the cold (colored) water sinks and moves along the bottom of the baking dish toward the warmer water in the middle; the warmer water moves toward the ends of the baking dish; as the cold water begins to warm, it begins to rise.6.Students should record the results of their experiment, accompanying their reports with labeled diagrams and an explanation of how differences in water temperature in different parts of the "world ocean" cause ocean currents.7.Have students use research materials and the Internet to find out more about ocean currents and how they affect our weather and life on Earth.

Adaptations

Adaptations for Older Students:
Suggest students read Kon-Tiki by Thor Heyerdahl to find out how the author replicated the voyage that ancient mariners may have made from Peru to Indonesia on primitive balsa rafts, guided only by ocean currents on which they floated.
