Introduction (10 - 12 minutes)

1. The teacher begins the lesson by reminding students of the previous lessons related to the Earth's structure and plate tectonics. This serves as a necessary point of reference for understanding the processes of earthquakes and volcanic eruptions. (2 - 3 minutes)

2. The teacher then proposes two problem situations to the students that serve as starters for the development of the theory. The first could be: "Imagine you live in a town near a volcano. Suddenly, there's an eruption. What would you do?" The second could be: "You are in a city that has just experienced a strong earthquake. How would you respond?" These scenarios are designed to pique students' interest in the topics and to make them aware of the real-world implications of these natural phenomena. (3 - 4 minutes)

3. The teacher then contextualizes the importance of the subject by discussing real-world applications. For example, the teacher can talk about how understanding earthquakes can help in the design of earthquake-resistant buildings, or how studying volcanic eruptions can aid in predicting and managing volcanic hazards. The teacher can also mention recent events like the 2010 earthquake in Haiti or the 2018 eruption of Kilauea in Hawaii to highlight the relevance of the topic. (2 - 3 minutes)

4. To introduce the topic and grab students' attention, the teacher shares two intriguing facts or stories related to earthquakes and volcanoes. The first could be about the largest earthquake ever recorded, the 1960 Great Chilean Earthquake, which had a magnitude of 9.5 and caused widespread destruction. The second could be about the volcanic eruption of Mount Vesuvius in 79 AD, which buried the Roman cities of Pompeii and Herculaneum under ash and pumice, preserving them for centuries and providing valuable insights into ancient Roman life. These stories are intended to spark students' curiosity and fascination with the subject. (3 - 4 minutes)

Development

Pre-Class Activities (15 - 20 minutes)

1. Reading: Students are assigned specific chapters or sections from their geography textbooks to read at home. The readings should provide students with basic knowledge about earthquakes and volcanoes, including their definitions, causes, and effects. Additionally, students should learn about the major geographical locations known for these phenomena. (Approximately 10 - 15 minutes)

2. Video Watching: The teacher provides the students with links to educational videos that further illustrate the concepts learned from the readings. These videos can feature animations or real-life footage of earthquakes and volcanic eruptions, making the topics more visually engaging and easier for students to comprehend. (Approximately 5 - 10 minutes)

3. Note-Taking: Students are required to take notes on the key points they gather from the readings and the videos. These notes will serve as a study guide and will be used during in-class activities. (Approximately 5 minutes)

In-Class Activities (25 - 30 minutes)

1. Interactive Discussion: The teacher starts the class by facilitating a group discussion based on the at-home activities. The students are divided into small groups and are asked to share and discuss the most important points from their readings and videos. The teacher circulates around the room, guiding the discussion, and answering any questions that may arise. (Approximately 10 - 12 minutes)

2. "Volcano and Earthquake Kit" Project: The teacher then introduces a hands-on group activity. Each group is provided with a "Volcano and Earthquake Kit" that contains materials such as clay, baking soda, vinegar, and a model of a city. The teacher explains that the groups will be using these materials to create a model volcano and a model earthquake. (Approximately 10 - 12 minutes)

• Volcano Model: Students use the clay to construct a volcano around a plastic bottle. Once the clay dries, they will pour a mixture of baking soda and vinegar into the bottle, causing a "volcanic eruption" (a harmless chemical reaction that simulates a volcanic eruption).

• Earthquake Model: Students place their city model on a tray filled with sand. Then, they shake the tray from the sides, simulating an earthquake. This activity helps students visualize the effects of earthquakes and volcanic eruptions, making the concepts more tangible and memorable.

3. Group Presentation: After all the groups have completed their models, each group presents their work to the class. They explain the processes of earthquakes and volcanic eruptions, and the effects these phenomena can have on human settlements. The teacher provides feedback and facilitates a discussion based on the presentations. (Approximately 5 - 6 minutes)

Feedback (8 - 10 minutes)

1. Group Discussion: The teacher should facilitate a whole-class discussion, where each group shares their conclusions or solutions from the group activities. The teacher encourages students to highlight the most important learnings from each group's presentation, fostering a collaborative learning environment where students can learn from each other. The teacher should use this opportunity to tie the students' findings back to the theoretical concepts discussed at the beginning of the lesson. (Approximately 5 minutes)

2. Connecting Theory and Practice: After the group discussions, the teacher should guide students in making connections between the hands-on activities and the theoretical knowledge they acquired. For instance, the teacher can ask questions like, "How did the 'Volcano and Earthquake Kit' activity help you understand the causes and effects of these phenomena?" or "What safety measures can we take to protect ourselves in case of an earthquake or volcanic eruption, based on what you observed in the 'Earthquake Model'?" This step is crucial in reinforcing the learned concepts and making them more applicable and relatable for the students. (Approximately 2 - 3 minutes)

3. Reflection Time: The teacher then proposes that the students take a moment to reflect on the day's lesson. The students are asked to think about the most important concept they learned, the questions they still have, and the real-world relevance of the topics discussed. To facilitate this reflection, the teacher can provide guiding questions such as:

   • What was the most important concept you learned today?
   • Which questions have not yet been answered?
   • How can the knowledge you gained today be applied in real life?
   • What measures can you take to stay safe in case of an earthquake or volcanic eruption in your area? This step encourages students to take ownership of their learning and to think critically about the topics. (Approximately 1 - 2 minutes)

4. Closing Remarks: To wrap up the lesson, the teacher addresses any remaining questions and provides a brief summary of the key points discussed. The teacher also emphasizes the importance of understanding and being prepared for natural hazards like earthquakes and volcanic eruptions, underscoring the real-world significance of the lesson's topic.
