Begin the lesson by discussing the concept of tornadoes and their formation during thunderstorms. Use engaging questions to spark curiosity about how these powerful weather phenomena occur.

Introduce the video 'Severe Weather' to provide a visual understanding of tornadoes and other extreme weather events. This video helps students visualize the formation and impact of tornadoes.

Explain the science behind tornado formation, focusing on how they develop from thunderstorms and the conditions required for their formation.

Discuss the effects of tornadoes on the Earth's surface and human structures, highlighting the importance of understanding these impacts for safety and preparedness.

Engage students in a discussion about the dangers of tornadoes and the importance of safety measures. Encourage them to share any personal experiences or stories they've heard about tornadoes.

Conduct a simple experiment to demonstrate the spinning motion of a tornado using a bottle and water. This hands-on activity helps students visualize the vortex formation in a tornado.

Assign students to research recent tornado events and present their findings to the class. This activity reinforces their understanding of tornado impacts and safety measures.

Use the 'Rapid Changes to the Earth’s Surface' assessment to evaluate students' understanding of how tornadoes and other natural events alter the Earth's surface.

Have students reflect on what they learned about tornadoes and their impacts. Encourage them to think about how this knowledge can be applied to real-life situations.

Conclude the lesson with a quiz to test comprehension of tornado formation, effects, and safety measures.

For further exploration, students can complete the 'Preventing Floods' assessment to understand how to mitigate the effects of other natural disasters.
