Begin the lesson by introducing the concept of tsunamis and their causes, such as underwater earthquakes, volcanic eruptions, landslides, and meteorite impacts. Use engaging visuals to capture students' interest.

Explain how tsunamis can cause significant damage to coastal areas by eroding land and destroying infrastructure. Use diagrams to illustrate the process of tsunami formation and impact.

Differentiate between tsunamis and tidal waves, emphasizing that tsunamis are not related to tides.

Watch the 'Severe Weather' video to understand how extreme weather phenomena, including tsunamis, form and impact the environment. This video supports discussions on mitigation strategies.

Create a model to simulate tsunami waves and observe their effects on coastal areas. This hands-on activity helps students visualize the impact of tsunamis on the environment.

Assign students to research historical examples of tsunamis, such as the 2004 Indonesia tsunami and the 2011 Fukushima tsunami, and the measures taken to prevent future disasters.

Discuss the role of detection tools and warning systems in tsunami preparedness and safety. Encourage students to share their research findings.

Reflect on the importance of understanding natural phenomena like tsunamis and the role of science in disaster preparedness.

Use the 'How Tsunamis Can Change the Coastline' assessment to evaluate students' understanding of tsunami impacts. This worksheet involves creating models and analyzing coastal changes.

Encourage students to try the quiz to test their comprehension of the unit on Processes That Shape the Earth.
