Begin with a captivating discussion on why Earth is called the 'blue marble' due to its water coverage. Use this to introduce the concept of Earth's water distribution, focusing on oceans.

Explain the process of salt accumulation in the ocean, highlighting the role of chemical erosion and ocean floor openings.

Discuss the depth variations of ocean water near land and in open sea areas, using diagrams to illustrate these differences.

Watch the video 'Glaciers and Icebergs' to understand how melting glaciers contribute to ocean water and the formation of icebergs.

Engage students in a hands-on activity where they create a model of the ocean floor, identifying features such as trenches, plains, and underwater volcanoes.

Assign students the task of researching and presenting on a specific ocean floor feature, explaining its formation and significance.

Use the assessment 'The Ocean' to evaluate students' understanding of oceanography and their ability to identify oceanic landforms.

Conduct a class discussion to reflect on the geological processes that shape ocean floor landforms, such as tectonic activity and erosion.

Encourage students to complete the 'Review – Mapping the Earth’s Surface' assessment to consolidate their understanding of Earth's surface features.

Direct students to the unit quiz to test their comprehension of the entire unit on Earth's water and ocean features.
