Begin with an engaging question: 'What do you think the bottom of the ocean looks like?' This will spark curiosity and set the stage for exploring ocean floor features.
Go to the LessonLearning Objectives
- Identify and describe key features of the ocean floor, including ocean trenches, abyssal plains, and ocean ridges.
- Explain the process of subduction and how it contributes to the formation of ocean trenches.
- Understand the role of tectonic plate movement in shaping ocean floor features such as ocean ridges and trenches.
- Compare and contrast ocean floor features with similar landforms on Earth's surface.
Introduction and Hook
Direct Instruction
Explain key features of the ocean floor, such as ocean trenches, abyssal plains, and ocean ridges, using diagrams and illustrations.
Discuss the process of subduction and how it contributes to the formation of ocean trenches, emphasizing tectonic plate movements.
Guided Exploration
Use interactive maps to explore different ocean floor features and compare them with similar landforms on Earth's surface.
Hands-On Activity
Have students create a 3D model of the ocean floor using clay or other materials to represent trenches, plains, and ridges.
Independent Practice
Assign students to research and write a short report on a specific ocean floor feature, such as the Mariana Trench or the Mid-Atlantic Ridge.
Check for Understanding
Conduct a class discussion to review the key concepts and ensure students can identify and describe ocean floor features.
Review and Reflection
Have students reflect on what they learned about ocean patterns and how these features compare to landforms they are familiar with.
Encourage students to share their 3D models and reports with the class, discussing what they found most interesting about the ocean floor.
Assessment and Extension
Administer the 'Review – Mapping the Earth’s Surface' assessment to evaluate students' understanding of the unit.
