   • The teacher will explain that understanding earthquakes and volcanoes can help predict and mitigate their effects, potentially saving lives and reducing property damage.
   • The teacher will also highlight how these natural events have shaped the Earth's geography, creating mountains, islands, and other unique landscapes.
   • The teacher may mention recent earthquakes or volcanic eruptions that have made the news, emphasizing that these are not just historical or remote events, but ongoing phenomena that continue to shape our planet. (2 - 3 minutes)

4. Introduce the topic with an engaging story or fact:

   • The teacher might share the story of the 1906 San Francisco earthquake, one of the most significant geological events in U.S. history, which led to major changes in how we design and construct buildings in earthquake-prone areas.
   • The teacher might also share the fact that there are over 1,500 active volcanoes in the world, and about 50 to 70 of them erupt each year, on average. This highlights the ongoing dynamic nature of our planet. (1 - 2 minutes)

By the end of the introduction, students should have a clear understanding of the topic, its relevance, and their role in the learning process. They should be excited to delve deeper into the subject and explore it through hands-on activities and experiments.

Development (20 - 25 minutes)

Activity 1: Simulating Earthquakes

The teacher will:

1. Divide the class into groups of 4 or 5 students and provide each group with the necessary materials: a tray with sand, some small wooden blocks, a spray bottle filled with water, and a small toy house. Each group will also receive a worksheet outlining the steps of the simulation, as well as questions to answer and observations to make. (2 - 3 minutes)

2. Guide the students through the process of creating an earthquake simulation. The teacher will explain that the sand represents the Earth's crust, the wooden blocks are tectonic plates, and the toy house is a structure on the Earth's surface. The teacher will then instruct the students to:

   • Place the wooden blocks on the sand, partially covering the toy house.
   • Spray water onto the sand to make it slightly wet.
   • Push one of the wooden blocks slowly towards the other, creating pressure.
   • After a certain point, release the block, allowing it to "snap back" into its original position. This represents an earthquake.

   As the students perform these steps, the teacher will circulate the room, ensuring that the students are following the instructions correctly and answering any questions that arise. (8 - 10 minutes)

3. Once the students have completed the earthquake simulation, the teacher will ask them to make observations and answer questions on their worksheet, such as:

   • What happened to the toy house during the earthquake?
   • Why did the earthquake occur?
   • How does this simulation represent a real earthquake?

   This will encourage the students to reflect on the simulation and connect it to the real-world phenomenon. (3 - 4 minutes)

Activity 2: Volcano Eruption Model

The teacher will:

1. Transition into the second half of the class by introducing the topic of volcanoes. The teacher will explain that like earthquakes, volcanic eruptions are the result of tectonic activity. The teacher will also highlight that unlike earthquakes, volcanic eruptions can be predicted in some cases, giving scientists the opportunity to evacuate people and mitigate damage. (2 - 3 minutes)

2. Distribute the materials for the next activity: a larger tray with sand, a plastic bottle, baking soda, red food coloring, dish soap, and vinegar. Each group will also receive a worksheet outlining the steps of the model, as well as questions to answer and observations to make. (2 - 3 minutes)

3. Instruct the students on how to create a volcano eruption model:

   • The students should shape the sand around the plastic bottle to resemble a volcano.
   • Next, they will add a couple of drops of red food coloring and a teaspoon of dish soap into the bottle.
   • Then, they will add 2 tablespoons of baking soda into the bottle.
   • Finally, they will carefully pour vinegar into the bottle.

   As with the previous activity, the teacher will monitor the groups, helping them if needed and addressing questions. (5 - 8 minutes)

4. Encourage the students to observe the eruption and answer the questions provided on their worksheets, such as:

   • What happened when you poured the vinegar into the bottle?
   • What caused the eruption?
   • How does this model represent a real volcanic eruption?

   The teacher will facilitate a brief class discussion about the eruption and its causes, ensuring that the students are making the connection between the model and real-world volcanoes. (3 - 4 minutes)

At the end of the development stage, the students should have a clear, hands-on understanding of earthquakes and volcanic eruptions, their causes, and their effects. They should have recorded their observations and answered reflective questions about the simulations and models, demonstrating their understanding of the topic.

Feedback (8 - 10 minutes)

The teacher will:

1. Facilitate a group discussion where each group shares their observations, answers to questions, and experiences during the hands-on activities. Each group will be given up to 3 minutes to present their findings. (5 - 6 minutes)

   • The teacher will encourage other students to ask questions or share their thoughts about the presented group's findings. This will foster an interactive and collaborative learning environment.
   • The teacher will highlight the key points from each group's presentation, ensuring that all students have a comprehensive understanding of the topic.

2. Connect the hands-on activities to the theory by explaining how the earthquake simulation and volcano eruption model represent real-world phenomena. The teacher will:

   • Reiterate the connection between tectonic activity and earthquakes/volcanic eruptions, emphasizing that the movement and collision of tectonic plates cause these natural events.
   • Explain that the pressure and release of energy in the earthquake simulation mimic the faulting process in the Earth's crust during an earthquake.
   • Highlight that the chemical reaction between baking soda and vinegar in the volcano eruption model represents the eruption of magma (molten rock) from a volcano.
   • Reinforce the idea that the hands-on activities were simplified representations of complex processes, but they provide a tangible and memorable way for the students to understand these phenomena. (2 - 3 minutes)

3. Encourage the students to reflect on their learning by posing several questions for the class to consider. The teacher will:

   • Ask, "What was the most important concept you learned today?" This will help the students identify the key takeaways from the lesson.
   • Ask, "What questions do you still have about earthquakes and volcanoes?" This will give the teacher insight into any areas of the topic that may need further clarification or exploration in future lessons.
   • Remind the students that understanding earthquakes and volcanoes is an ongoing process, and there is always more to learn. The teacher will also stress the importance of curiosity and active inquiry in the learning process. (1 - 2 minutes)

By the end of the feedback stage, the students should have a solid understanding of earthquakes and volcanoes, their causes, and their effects. They should also have a clear understanding of the connection between the hands-on activities and the real-world phenomena they represent.
