Begin the lesson with an engaging discussion on the importance of ecosystems and how both living (biotic) and non-living (abiotic) factors contribute to their balance.

Introduce biotic and abiotic factors using examples from various ecosystems, such as forests and deserts. Highlight how these factors interact and support each other.

Utilize the video 'Ecosystem Organisation' to demonstrate the levels of organization within ecosystems and the interactions between biotic and abiotic components.

Watch the video 'Abiotic Factors in Ecosystems – Water' to explore the role of water in ecosystems, emphasizing its impact on plant photosynthesis and organism diversity.

Engage students in identifying biotic and abiotic factors in their local environment and discuss how they interact.

Conduct a classroom activity where students classify various items as biotic or abiotic and explain their roles in an ecosystem.

Use the 'Biotic and Abiotic Factors' assessment to reinforce learning by having students draw or paste pictures of ecosystems and list the factors.

Assign students to research and present on a specific ecosystem, identifying its biotic and abiotic factors and their interactions.

Facilitate a class discussion to review key concepts and ask students to provide examples of how changes in abiotic factors can affect biotic components.

Reflect on the importance of maintaining balance in ecosystems and discuss human impacts on biotic and abiotic factors.

Administer the 'Sunlight – Comprehension' assessment to evaluate students' understanding of sunlight as an abiotic factor.

Encourage students to explore further by researching the impact of climate change on abiotic factors and presenting their findings.
