Quick summary: In this lesson, students will learn about biodiversity and the role keystone species play in the health of an ecosystem. They will then research the Black Summer Australian bushfires as a case study of an event that had significant biodiversity loss. Using the information learnt, they will write a letter to the government to convince them to enact change in how Australia manages the land and conserves biodiversity.
- Students understand the importance of biodiversity in an ecosystem
- Students understand the important role a keystone species plays
