Understanding Ocean Currents and Climate

The video lesson explores the topic of ocean currents, focusing on why Christchurch, New Zealand, experiences cooler temperatures during El Nino years. It begins with an introduction to the lesson and the materials needed. The lesson then delves into the analysis of temperature graphs, showing that both air and ocean surface temperatures are cooler during El Nino years, despite the same amount of solar energy. The video discusses factors affecting Christchurch's temperature, such as latitude and ocean currents from the equator. Finally, it explores what causes ocean currents and encourages students to think about these factors.

What materials are suggested for students to have during the lesson?

• A computer and internet connection

• A notebook and a pen

• A calculator and a ruler

• A textbook and a highlighter

What is the main question posed by the New Zealand farm council?
