**Duration:** 1 hour
---
**Objective:**
Students will:
1. Understand what volcanoes and earthquakes are.
2. Learn about the causes and effects of these Earth's processes.
3. Explore the safety measures to take during these natural events.

**Lesson Activities:**
**1. Introduction (10 minutes):**
- Begin with a brief discussion: "What do you know about volcanoes and earthquakes?"
- Show a short, engaging video clip about volcanoes and earthquakes.
**2. Direct Instruction (15 minutes):**
- Explain what volcanoes and earthquakes are using diagrams and simplified definitions.
- **Volcano:** A mountain where magma (molten rock) comes out from beneath the Earth's crust.
- **Earthquake:** A sudden and violent shaking of the ground, usually caused by movement of tectonic plates.
- Discuss the causes of each process:
- **Volcanoes:** Formed by movement of tectonic plates, causing pressure and magma to burst out.
- **Earthquakes:** Caused by the slipping or movement along fault lines in the Earth’s crust.
- Introduce key terms and their meanings using visual aids (illustrations on the board).
**3. Interactive Activity (20 minutes):**
- Divide students into small groups.
- Hand out materials for constructing simple volcano models using playdough.
- Instruct groups to build a model volcano and demonstrate an "eruption" using baking soda and vinegar (handled by the teacher if necessary for safety).
**4. Guided Practice (10 minutes):**
- Hand out worksheets with a section to label parts of a volcano and earthquake-related questions.
- Walk around and assist students as they fill out their worksheets.
**5. Video and Safety Discussion (10 minutes):**
- Show a short video demonstrating safety measures during an earthquake (Drop, Cover, and Hold On).
- Discuss what to do if a volcano erupts nearby (evacuation plans, following adults' instructions).
**6. Conclusion (5 minutes):**
- Recap what was learned about volcanoes and earthquakes.
- Ask a few students to share one interesting fact they learned.
**Homework:**
- Assign a simple research task: Find a famous volcano or earthquake and write a short paragraph about it.
---
**Assessment:**
- Participation in group activity and building the volcano model.
- Accuracy and completeness of the worksheet.
- Engagement and responses during discussions.
---
**Differentiation:**
- Provide additional visual supports and simplified texts for students who need them.
- Offer more challenging extension activities (e.g., research projects, detailed diagrams) for advanced students.
- Utilize peer support and group work for collaborative learning.
---
**Reflection:**
After the lesson, reflect on what worked well and what could be improved. Consider student engagement, understanding, and participation in the activities. Adjust future lessons based on these observations.
