2. THE SCENARIO: An alien spaceship from Zarg has landed in central Australia. It plans to absorb the whole of Australia as we are a country of great thinkers and inventors. However, after much negotiating they have agreed to leave Australia on Earth if we provide them with the details of our 5 most ‘important’ inventions. You, yes you, have been given this very important task.

3. THE TASK: Look at the following database, and choose the 5 most ‘important’ Australian inventions. http://www.whitehat.com.au/Australia/Inventions/InventionsA.html To ensure Australia remains safe, you must give reasons as to why you chose the inventions you have and present them in a PowerPoint format for the Zarg leaders to view. The survival of Australia is in YOUR hands. So, please, be persuasive and creative in your final presentation.

4. Good Luck!!! Time is of the essence. In Zarg, 1 Earth hour is equal to 4 weeks!!!
