Begin the lesson by discussing the concept of natural hazards and their impact on Earth's surface. Introduce floods as a key example of a rapid change process.

Show a video clip of a flood event to capture students' interest and provide a visual understanding of the topic.

Explain the causes of floods, including heavy rainfall and human activities, and their effects on landscapes through erosion and deposition.

Use diagrams to illustrate how rapid erosion and deposition during floods can alter riverbanks and other landforms.

Watch the 'Severe Weather' video to understand various severe weather events, including floods, and their environmental impacts.

Engage students in a discussion about how floods can change landscapes and the role of fast-flowing water in soil and rock movement.

Conduct a model-building activity where students simulate a flood using materials like soil and water to observe erosion and deposition.

Use the 'The Impacts of Floods' assessment to guide students in building a river model and observing flood effects.

Assign students to research a recent flood event and present their findings on its causes and effects on the local landscape.

Use a quick quiz to assess students' understanding of how floods cause rapid changes to the Earth's surface.

Have students reflect on what they learned about floods and discuss how human activities can mitigate or exacerbate flood impacts.

Provide the 'Comprehension – Erosion' assessment to evaluate students' understanding of erosion processes during floods.

Encourage students to explore further by researching flood prevention strategies and presenting their ideas.
