Warm seas, cold seas, ocean currents

What makes one sea warm and another sea cold? What makes water flow from one part of the world to another? And how does this affect where we find life in the oceans of the world?

In this activity you and your students will:

• Carry out some simple experiments that explain the basics of ocean currents.
• Carry out some experiments that show the conditions plant life needs to thrive and how this relates to water temperature.
• Learn about the impact this has on the diversity and location of marine life.
• Create maps showing the major ocean currents and life ‘hotspots’.
