# Lesson Plan: Action of Glaciers
**Grade Level:** Senior Secondary 2
**Subject:** Geography
**Lesson Duration:** 90 minutes
## Lesson Objectives:
By the end of this lesson, students will be able to:
1. Define glaciers and explain their formation.
2. Describe the different types of glaciers.
3. Explain the processes of glacial erosion, transportation, and deposition.
4. Identify and describe various glacial landforms.
5. Appreciate the role of glaciers in shaping the Earth's landscape.
## Materials Needed:
- Projector and computer for multimedia presentations
- Whiteboard and markers
- Physical maps showing glacial regions
- Handouts with key terms and diagrams
- Worksheets for small group activities
- Videos or animations about glaciers (optional but recommended)
## Lesson Structure:
### Introduction (10 minutes)
1. **Hook Activity:** Begin with a brief video or a series of dramatic photographs showcasing glaciers around the world.
2. **Discussion:** Ask students what they know about glaciers and their importance. List their ideas on the whiteboard.
3. **Learning Objectives:** Briefly go over the lesson objectives.
### Instructional Input (25 minutes)
1. **Explanation and Definition:**
- Define what a glacier is: A large mass of ice that moves slowly over land.
- Explain how glaciers are formed from the accumulation and compaction of snow over many years.
2. **Types of Glaciers:**
- Continental Glaciers (Ice Sheets) e.g., Antarctica and Greenland.
- Alpine or Valley Glaciers, found in mountain ranges around the world.
- Show images or diagrams to illustrate the differences.
3. **Processes:**
- **Glacial Erosion:** Describe processes like plucking and abrasion.
- **Transportation:** How glaciers carry debris along as they move.
- **Deposition:** Explain features like moraines, drumlins, and till.
### Interactive Activity (20 minutes)
1. **Group Activity:** Divide students into small groups and give each group a set of questions or a worksheet. The questions could involve identifying the processes of glacial erosion in images, matching terminology, or labeling diagrams of glacial landforms.
2. **Class Discussion:** After completing the worksheets, have each group present their answers. Encourage discussion and provide corrections as necessary.
### Multimedia Segment (15 minutes)
1. **Video Presentation:** Show a short video or animation explaining glacial movements and the formation of glacial features. (National Geographic, BBC, or similar reputable sources.)
2. **Discussion:** Ask students to reflect on and discuss the new information from the video. How do the processes they just learned about shape the landscape?
### Application Activity (15 minutes)
1. **Case Study:** Provide a real-world example of a glacial environment (e.g., the Alps, the Rocky Mountains, or Antarctica). Describe its key features and explain the impact of glaciers on the area's geography.
2. **Map Analysis:** Give students maps that show regions currently or previously impacted by glaciers, and ask them to identify possible glacial features.
### Review and Conclusion (5 minutes)
1. **Summary:** Go over the key points of the lesson, emphasizing the importance of glaciers in shaping the landscape.
2. **Q&A:** Allow students to ask any remaining questions about the topic.
3. **Exit Ticket:** Ask each student to write down one interesting fact they learned about glaciers and one question they still have.
### Homework:
Assign students to research a specific glacier or glacial region and prepare a one-page report that includes its location, type, formation processes, and impact on the environment.
## Additional Resources:
1. National Geographic website on glaciers
2. NASA Earth Observatory: Glacier Facts and Images
3. Textbook chapters on glaciation and landforms
## Assessment:
1. Formative assessment through group activities and discussions.
2. Review of homework reports to assess understanding and ability to research and present geographical information.
This lesson plan aims to engage students through a mix of direct instruction, multimedia resources, and interactive activities, ensuring a comprehensive understanding of the actions of glaciers.
