Begin the lesson by introducing the concept of different feeding habits among animals, including herbivores, carnivores, omnivores, and scavengers. Use engaging questions to spark curiosity about how these animals obtain their food.

Explain the role of scavengers in the ecosystem and how they contribute to environmental health. Discuss examples of scavengers such as hyenas, vultures, and the white ibis in urban environments.

Watch the video 'Scavengers' to understand how these animals fit into the food web and their importance in maintaining ecological balance.

Explore how urban environments influence the feeding behaviors of scavengers using the example of the white ibis, also known as the 'bin chicken'.

Watch the video 'Meet the Cleanup Crew: Detritivores and Their Role in Nature' to understand the broader ecosystem roles of organisms that break down dead organic matter.

Have students classify different animals based on their feeding habits. Use images or models to sort them into categories: herbivores, carnivores, omnivores, and scavengers.

Assign students to research and present on a scavenger of their choice, focusing on its role in the ecosystem and any adaptations to urban environments.

Use the assessment 'Identifying Biotic and Abiotic Factors' to evaluate students' understanding of ecosystem dynamics and the interaction between living and non-living components.

Encourage students to reflect on the importance of scavengers in ecosystems and how human activities impact their roles. Discuss how these changes might affect ecosystem health.

Test comprehension with the 'Food Chains' assessment, which helps students demonstrate understanding of energy pathways in ecosystems.

For further exploration, students can create a presentation on how scavengers adapt to different environments, focusing on urban versus natural settings.
