Year 9 Lesson 3 - Catalyst Video - impacts of 2009 Floods

Lesson 3 - Catalyst 

Watch the Catalyst Video on Moreton Bay and the effects of the Brisbane River Floods entitled Coastal Flood Impact at www.abc.net.au/catalyst/stories/3480317.htm. On compass there is a worksheet with the following questions to complete and submit back through compass.

Even though this video focuses on human impacts, it gives a good introduction to Moreton Bay. It provides students with a visual reference, introduces them to new terminology (such as sediment, catchment and ecosystem), and presents human impacts. Watch the video with the students and have them answer the questions. 

Questions:

1.What is this video focusing on?

2.It is estimated that pre‐European times, the Brisbane River carried twenty thousand tonnes of mud to Moreton Bay. What is the figure today, and how much was estimated in the Brisbane floods? 

3.What are the differences in the last century that may account for these changes? 

4.How different is the ecosystem in the eastern side of the bay to the western side? 

5.What impacts did the scientists/ecologists expect to see in Moreton Bay? 

6.Why is seagrass important? 

7.How does flooding affect seagrasses? 

8.How do the scientists/ecologists test the seagrass for impacts? 

9. What did they find? 

10.How else have the scientists/ecologists been testing the health of Moreton Bay and what did they find? 

11.Why do the scientists/ecologists think that the eastern side of the bay suffered more than the western side?

 Once the students have completed the questions, please encourage them to read through my blog posts on this TeachLive site. They will give the students a clear insight into the day-to-day activities we are undertaking as we conduct research into the impacts of urbanisation of the Brisbane River Catchment on Moreton Bay.
