Objectives:

Understand the concept of earthquakes, their causes, and types of faults.
Recognize the dangers of earthquakes and learn safety measures.
Explore the phenomenon of tsunamis, their causes, and preventive actions.
Familiarize students with the geography of earthquake-prone regions.

Materials:

Visual aids (images or diagrams of earthquake faults, tsunamis, and safety measures)
Examples of earthquake-resistant buildings and structures
News articles or video clips depicting real-life earthquake incidents and tsunamis, if available

Introduction (3 minutes):

Recap the concept of natural disasters as catastrophic events caused by natural processes on Earth.
Define earthquakes as sudden releases of energy in the Earth’s crust, causing ground shaking.
Highlight the dynamic nature of Earth’s surface and its constant changes.

Activity 1 – What are Earthquakes? (16 minutes):

Explain that tectonic plates are the rocks that make up Earth’s crust and that they fit together like puzzle pieces. At the edges where two plates meet, there are cracks in the crust, like the cracks you’d find between two puzzle pieces. These cracks are called faults. Faults are where the plates move and shift against each other. Explain that earthquakes are the result of two tectonic plates in earth’s crust pushing or sliding against each other.

Introduce the three types of earthquake faults: normal, reverse, and strike-slip. Normal faults happen when two blocks of the Earth’s crust move away from each other. Reverse faults occur when two blocks of the Earth’s crust move towards each other. And strike-slip faults occur when two blocks of the Earth’s crust move past each other. All of these create stress that can cause an earthquake. Use visual aids such as videos or images to illustrate fault movements and their effects.

Provide historical examples of devastating earthquakes and their impact. Highlight the importance of earthquake-resistant building designs. Detail safety measures during an earthquake: finding a safe place, staying indoors, and protecting oneself.

Activity 2 – What is a Tsunami? (8 minutes):

Define tsunamis as large waves caused by undersea earthquakes. Discuss other causes of tsunamis: underwater landslides, volcanic eruptions, and meteorite impacts. Emphasize the sudden and destructive nature of tsunamis. Discuss the geography of tsunami-prone regions. Use visual aids such as videos or images. Explain the importance of having an evacuation plan for people living in tsunami-prone regions.

Conclusion (3 minutes):

Summarize key points: earthquakes, faults, dangers, and safety measures.
Emphasize the importance of community preparedness and understanding one’s geographical location.

Assessment:

Informally assess student participation during class discussions and activities.
