Pre-lesson Discussion:
- Start by discussing what erosion is and how it can change the shape of the land.
- Show pictures or videos illustrating erosion and its effects.
Lesson Activities:
-
Introduction to Erosion (DCI):
- Discuss with students the concept of erosion and how wind and water can change the shape of the land.
- Ask students to share any observations or experiences related to erosion.
-
Exploration of Erosion Control Solutions (SEP):
- Present images or diagrams of different erosion control solutions such as dikes, windbreaks, and vegetation.
- Discuss the purposes and mechanisms of each solution.
-
Hands-On Modeling (SEP):
- Provide small containers filled with soil for each student or group.
- Use small fans or hairdryers to simulate wind or watering cans to simulate water erosion.
- Have students design and build models of erosion control solutions using craft materials.
-
Comparison and Discussion (SEP):
- Allow students to share and demonstrate their erosion control models.
- Record ideas on a chart paper or whiteboard, highlighting the strengths and limitations of each solution.
Teacher Notes:
- Emphasize the importance of protecting the land from erosion for the stability of landscapes and ecosystems.
- Encourage creativity in designing erosion control solutions.
- Consider allowing students to refine and improve their models based on the group discussion and analysis.
- Encourage students to research and explore real-world examples of erosion control solutions used in different environments.
Conclusion:
Wrap up the lesson by summarizing the importance of erosion control solutions and their role in maintaining the stability of the land. Reinforce the idea that different environments may require different solutions. Encourage students to think about the impact of their designs on preventing erosion.
This lesson plan integrates the NGSS standard 2-ESS2-1, emphasizing the understanding of erosion, exploring different solutions, and developing models to address the issue.
