Erosion and Deposition
Learning Objectives
- Understand the processes of erosion and deposition and how they shape the Earth's surface.
- Identify the causes of erosion, such as moving water and wind, and how they contribute to landscape changes.
- Recognize the role of natural events like floods and hurricanes in accelerating erosion.
- Explain how deposition moves materials like rocks and sand to new locations, altering the landscape.
Introduction and Hook
Show a time-lapse video of a landscape changing due to erosion and deposition over time to visually demonstrate these processes.
Direct Instruction
Explain the processes of erosion and deposition in detail, highlighting how they shape the Earth's surface. Use diagrams and illustrations to support understanding.
Discuss the causes of erosion, such as water and wind, and how natural events like floods and hurricanes can accelerate these processes.
Guided Exploration
Engage students in a discussion about how erosion and deposition affect their local environment. Encourage them to share observations or experiences.
Watch a video on the effects of erosion and deposition in various landscapes to reinforce learning.
Hands-On Activity
Conduct an experiment to simulate erosion and deposition using sand, water, and wind. Have students observe and record the changes.
Use the 'Make a Model of a Volcano' assessment to explore how volcanic eruptions contribute to changes in the Earth's surface.
Independent Practice
Assign students to research a local area affected by erosion or deposition and prepare a short presentation on their findings.
Check for Understanding
Use the 'Rapid Changes to the Earth’s Surface' assessment to evaluate students' understanding of how natural events impact the Earth's surface.
Review and Reflection
Have students reflect on what they learned about erosion and deposition. Encourage them to write a short paragraph summarizing their understanding.
Assessment and Extension
Administer a quiz to test comprehension of erosion and deposition concepts.
Try the QuizFor further exploration, use the 'Preventing Floods' assessment to engage students in designing solutions to mitigate the effects of erosion.
