Begin the lesson with a discussion on the importance of water in daily life and how its availability changes with seasons. Introduce the concept of reservoirs as a solution for water storage.

Explain how reservoirs store water and provide a year-round supply for human use. Discuss the various uses of reservoirs, including water supply, electricity generation, and recreation.

Use the video 'Storing Water' to illustrate different methods of water storage and their importance in managing water resources effectively.

Explore the impact of pollution on stored water and its consequences for human use and ecosystems. Discuss how pollution can make water unsafe and unsuitable for use.

Watch 'The World of Freshwater' video to understand the role of freshwater in ecosystems and the impact of human activities on these resources.

Engage students in a project to design a model of a reservoir using simple materials. Encourage them to think about how their design can store and manage water effectively.

Assign the 'Storing Water' assessment to reinforce the concept of water storage and its importance. This task will help students analyze material properties and design functionality.

Conduct a class discussion to review the key concepts learned about reservoirs and water storage. Encourage students to share their thoughts on the importance of water management.

Ask students to reflect on the role of reservoirs in their community and how they contribute to sustainable water use.

Use the 'Water Around the World' assessment to evaluate students' understanding of different water sources and their characteristics.
