### Lesson Plan: Rocks - Senior Secondary 1 (Geography)
**Grade Level:** Senior Secondary 1 (Equivalent to 10th Grade in US high schools)
**Subject:** Geography
**Lesson Topic:** Rocks
**Duration:** 60 minutes
---
#### **Objectives:**
By the end of this lesson, students will:
1. Identify the three main types of rocks: igneous, sedimentary, and metamorphic.
2. Understand the formation processes for each type of rock.
3. Recognize examples of each rock type.
4. Explain the rock cycle and its significance in the Earth's geology.
---
#### **Materials Needed:**
- Textbook or handouts on rocks
- Sample rocks (igneous, sedimentary, and metamorphic)
- Chart paper and markers
- Projector/Whiteboard
- Rock Cycle Diagram
- Laptops/tablets for online research (if available)
---
#### **Lesson Structure:**
**1. Introduction (10 minutes)**
- **Engage:** Start with a short video clip or slideshow showcasing various landscapes and geological formations. Ask students to observe and note down any different types of rocks they see.
- **Discussion:** Briefly discuss the observations and introduce the topic by asking:
- What do you know about rocks?
- Can you name different types of rocks?
- **Objective Sharing:** Let students know what they will learn during the lesson.
**2. Direct Instruction (15 minutes)**
- **Types of Rocks:**
- **Igneous Rocks:** Formed by the cooling and solidification of magma or lava. Examples include granite and basalt.
- **Sedimentary Rocks:** Formed by the accumulation and cementation of mineral and organic particles. Examples include sandstone and limestone.
- **Metamorphic Rocks:** Formed when existing rocks are subjected to heat and pressure but do not melt. Examples include marble and slate.
- **Interactive Discussion:** Pass around sample rocks, if available, for students to examine.
**3. Guided Practice (15 minutes)**
- **Rock Cycle Diagram:**
- Draw a basic rock cycle diagram on the whiteboard or display it using a projector.
- Explain the processes: cooling, weathering, deposition, compaction, cementation, and metamorphism.
- Discuss how the rock cycle is a continuous process and how rocks can transform from one type to another.
**4. Collaborative Activity (10 minutes)**
- **Group Work:** Divide students into small groups and assign each group a type of rock.
- **Task:** Each group will:
- Research the formation process of their assigned rock type.
- Identify common locations where these rocks are found.
- Find out how these rocks are used in daily life or various industries.
- **Presentation:** Each group will present their findings to the class.
**5. Individual Activity (5 minutes)**
- **Worksheet:** Hand out a worksheet with questions related to the lesson. Examples:
- Define igneous, sedimentary, and metamorphic rocks.
- Give two examples of each rock type.
- Describe the process of the rock cycle.
**6. Closing (5 minutes)**
- **Review and Recap:**
- Summarize the key points discussed in the lesson.
- Answer any remaining questions.
- **Exit Ticket:** Ask students to write down one new thing they learned about rocks and one question they still have.
---
**Assessment:**
- Group presentation and participation in discussion.
- Completion of the worksheet.
- Participation in the exit ticket activity.
---
**Homework / Extension Activity:**
- Ask students to collect different types of rocks from their surroundings as a weekend activity and classify them based on what they have learned.
- Encourage students to use online resources to explore more about unusual and interesting rocks and share their findings in the next class.

This lesson plan should provide an engaging and comprehensive introduction to the topic of rocks while encouraging interactive learning and critical thinking among students.
