2. Key Safety Measures

Below are some safety tips for what to do during a tsunami:

• Listen to local instructions.
• Move to higher ground immediately.
• Stay calm and help others if you can.

Question: Why do you think it is important to quickly move to higher ground during a tsunami?

3. Personal Safety Plan

Imagine that you are at home and you suddenly hear a tsunami warning. Think about the steps you should take to stay safe.

Question: Write down the steps you would take if you heard a tsunami warning. Consider what you know about safety and what you might do in your community.

4. Reflection

Reflect on these safety guidelines and how they might help keep you and your family safe during an emergency.

Question: What is one new thing you learned about tsunami safety, and how might it help you or someone else in a real situation?

Keep this handout as a reminder of what to do during a tsunami. Stay safe and remember to always follow the guidance of local authorities.

Tsunami Interactive Activities

Below are a series of interactive activities designed to enhance student engagement and deepen understanding of tsunamis. These activities include hands-on experiments, group discussions, and creative projects to accommodate diverse learning styles, especially supporting students on IEPs.

1. Hands-On Wave Simulation Experiment

Activity Overview:

• Students will create a simple wave simulation using a shallow tray, water, and objects (like small toy boats or blocks) to explore how tsunamis form and move.
• This activity provides a tactile and visual learning experience.

Guidelines & Steps:

1. Setup: Divide students into small groups. Provide each group with a tray filled with a shallow layer of water and objects to represent islands or obstacles.
2. Experiment: Ask students to gently disturb the water (by swishing their fingers or tapping the tray) and observe how waves move and interact with the objects in the tray.
3. Observation: Have each group note how different disturbances (such as a slow push versus a quick stir) create different wave patterns.
4. Discussion: Discuss why tsunamis can be so powerful and the potential effects on both the environment and human communities.

Question for reflection: What did you notice about how waves behave when they are created differently?

2. Group Discussion: Tsunami Impact and Preparedness

Activity Overview:

• Facilitate a structured group discussion where students share their thoughts on how tsunamis impact communities and what measures should be taken to stay safe.

Guidelines & Steps:

1. Discussion Prompt: Ask students, "How can communities be better prepared for tsunamis, and what actions can help save lives?"
2. Small Groups: Break the class into small discussion groups, including the student on the IEP with extra support if necessary.
3. Sharing Ideas: Have each group compile a list of ideas on large chart paper or a whiteboard. Encourage every student to share their thoughts.
4. Debrief: Bring the class together to review the ideas and underline common themes in effective tsunami preparedness.

Group Question: Which one safety measure do you think is most critical during a tsunami, and why?

3. Creative Project: Tsunami Safety Poster

Activity Overview:

• Students will design informative safety posters that highlight key information about tsunamis and safety precautions. This creative project supports visual learning and reinforces key facts from the lesson.

Guidelines & Steps:

1. Project Brief: Explain that each student or small group is tasked with creating a poster that includes the following:
   • A definition of a tsunami in their own words.
   • At least three key causes or effects of tsunamis.
   • Important safety tips during a tsunami, referencing the Tsunami Safety Guidelines Handout.
2. Materials: Provide art supplies such as paper, markers, crayons, and any digital tools available if a digital poster is preferred.
3. Presentation: Once completed, have students present their posters to the class and explain their design choices.
4. Reflection: Ask students to reflect on their learning. How did creating the poster help them understand tsunami safety better?

Prompt: What creative element did you include in your poster to emphasize tsunami safety, and why did you choose it?

These interactive activities are designed to reinforce student understanding of tsunamis while active participation, creativity, and group collaboration ensure that learning is engaging and inclusive for all students.

Understanding Tsunamis: A Natural Phenomenon

Tsunamis are one of nature's most powerful forces. They are giant waves that can travel across entire oceans, often moving faster than a car on a highway. Tsunamis usually form after underwater disturbances, such as earthquakes, volcanic eruptions, or landslides, which displace a large amount of water.

How Tsunamis Form

When an earthquake occurs beneath the ocean floor, the ground shifts suddenly. This rapid movement displaces the water above it, creating waves that travel outward in all directions. Although these waves might be small in the deep ocean, they can grow dramatically in height as they approach shallow coastal waters. This is why tsunamis become so dangerous when they reach land.

Effects of Tsunamis

Once tsunamis hit the coast, they can cause tremendous destruction. The massive waves can flood coastal areas, wash away buildings, and change the landscape. Besides physical destruction, tsunamis can also pose serious risks to human lives. The strong water currents can sweep people and vehicles off the road, making rescue efforts challenging.

Safety Measures During a Tsunami

Knowing what to do during a tsunami can save lives. Here are some important safety tips:

• Listen to local warnings: Authorities will inform you when a tsunami is coming.
• Move to higher ground immediately: This reduces the risk of being caught in the surge of the waves.
• Stay calm and help others: Panicking can make the situation more dangerous. Help those who might need assistance.

Real-Life Examples and Preparedness

Communities in tsunami-prone areas often prepare for these events. They hold regular drills and have warning systems in place to alert residents. By understanding how tsunamis form and knowing the safety measures, people can be better prepared and help keep themselves and others safe.
