Begin the lesson by discussing the concept of ecosystems and how they are constantly changing due to natural and human-induced factors. Highlight the importance of understanding these changes and their impacts on living organisms.

Explain the impact of natural hazards and human activities on ecosystems, using examples such as deforestation and pollution. Discuss how these changes affect both abiotic and biotic factors.

Introduce the concept of habitat destruction and its consequences on species survival, with a focus on orangutans and deforestation.

Watch the video 'Mangroves – Guardians of the Coast' to explore how mangroves adapt to their environment and their ecological importance. This video supports understanding of plant adaptations and conservation efforts.

Engage students in a discussion about the threats to orangutans due to habitat loss, encouraging them to identify other species that face similar challenges.

Conduct the 'Design and Build a Cabbage Protector' activity, where students apply their understanding of adaptations by designing a solution inspired by desert plant adaptations.

Assign the 'Animal Adaptations Research Project' to encourage students to research and describe their favorite animal's habitat and adaptations. This project assesses their understanding of how adaptations aid survival.

Facilitate a class discussion to differentiate between endangered and extinct species, and explore the factors leading to these conditions. Use examples from the lesson to reinforce understanding.

Review key concepts of the lesson, including the impact of ecosystem changes and the importance of adaptations. Encourage students to reflect on how human actions can mitigate negative impacts on ecosystems.

Use the 'Adapting to Changes' assessment to evaluate students' understanding of human impact on ecosystems and animal adaptation strategies.

Encourage students to take the unit quiz to test their comprehension of the topic.
