This document provides an overview of a unit on endangered species in Australia. It discusses how over 200 years, many Australian species have gone extinct due to human activity that destroys habitats and introduces invasive species. Currently around 40 mammal species and hundreds of plant species are endangered. The document outlines two assessment tasks for students - writing reflections on videos about saving wildlife and creating online posters about endangered species. It also details a third assessment involving researching threatened local species, writing stories about their past and future, and creating audio presentations to share with the class. The overall goals are for students to understand why species become endangered and what can be done to protect them.
