Revise the content of the unit so far. Ask the students:
- What are some of the problems associated with natural resource use in the 21st century?
- Do you think we are currently using natural resources in a responsible manner?
- How do our actions need to change in the future?
Write the word 'sustainability' on the board. Encourage the students to share their ideas about what this concept might mean. Do not be concerned if the students have few ideas to contribute at this stage.
Watch the What is Sustainability? video on YouTube. After watching, use the information presented in the video to create a simple definition of sustainability as a class.

Display slide 4 (the title slide) of the Caring for Country and Place in Sustainable Ways PowerPoint. Using the visual clues on the slide, guide the students towards identifying Aboriginal and Torres Strait Islander peoples as experts in sustainable living.
Display and discuss slides 6-9. Ensure that the students understand that Aboriginal and Torres Strait Islander peoples:
- have a deep connection to their Country/Place
- take only what they need to survive from the land and water
- adapt to the environment in which they live.

Watch the Welcome to Kakadu: Caring for Country video on the ABC Education website. After watching, ask the students:
- What were some of the foods sources mentioned in the video?
- How is burning used to care for and maintain the land?
- Why is it important for this knowledge to be passed on to future generations?
Display and discuss the class activity on slide 10. Ask the students to imagine what their local area might have looked like prior to European arrival. Using the questions on the slide as a prompt, create a list of natural resources that might have been useful to an Indigenous hunter-gatherer. Encourage the students to suggest how each of these natural resources might have been used e.g. fish for food, animal skins for clothes, plants for tools.

To revise the concept of sustainability, read through the dot points about sustainable living on slide 5.
