Introduce the topic and capture students' interest by presenting a vivid image or video clip (if available) of a tsunami. Briefly mention that today's lesson will explore what tsunamis are, what causes them, and how we can stay safe.

Explain the definition of a tsunami. Use simple language and visuals to ensure that the student on the IEP, as well as all other students, can grasp the idea of a massive, powerful wave.

Discuss the causes and the effects of tsunamis. Use the lesson plan visuals and the interactive simulation to demonstrate how energy is transferred and how waves travel.

Introduce the interactive simulation. Explain how the simulation works and encourage students to observe how a small disturbance can lead to large waves.

Go over the tsunami safety measures listed on the handout. Ask questions along the way to ensure students understand and relate to the safety tips.

Engage the class in a role-play or interactive discussion. Ask students to imagine what they would do during a tsunami. Encourage sharing and validate all contributions, especially from the IEP student.

Summarize the lesson by revisiting the key points: definition, causes, effects, and safety measures of tsunamis. Invite any final questions and express enthusiasm for learning about natural phenomena.
