Marine Animal Classification and Food Webs
Hands on classification activities with live animals to investigate the similarities and differences between groups of marine organisms and how they fit into marine food webs.
Fishing for the Future
Aquaculture is a major industry in Tasmania and food security is of ever increasing importance with exponentially expanding population. We take the RV Penghana to a fish farm lease and discuss some of the ways aquaculture systems operate and learn about scientific data collection for water quality testing.
Body Structures and Cells
Focusing on cells and body organs, students investigate the physiological adaptations of marine animals that allow them to survive underwater such as gills, sensory organs and reproductive strategies. Use microscopes to view plankton and discuss cell differences between phytoplankton and zooplankton.
We discuss how different rock type causes different types of sand and sediment and high energy and low energy coasts. Use the Van Veen Grab on board RV Penghana to take sediment samples from the sea floor of the channel and use the remotely controlled underwater vehicle to conduct a seafloor survey.
Marine Ecosystems and Human Impacts
Discussion on biotic and abiotic factors of marine ecosystems and the complex balance of marine ecosystem dynamics. Case studies include the long-spined sea urchin, Northern Pacific Sea Star, and the changes in the East Australian Current.
Marine Animal Body Systems
Students investigate the physiological adaptations of marine animals that allow them to survive underwater. Students will be able to hold live animals and compare and contrast different phyla.
DNA and Natural Selection
Using a case study of jellyfish blooms, we examine the life cycle of jellyfish to discuss meiosis and mitosis (sexual and asexual reproduction) and how natural selection may favour jellyfish with some human induced changes to the ocean ecosystem.
Ocean Acidification and Climate Change
Study the carbon cycle in relation ocean acidification and climate change, as well as understanding why the east coast of Tasmania is warming at a higher rate than the global average. Practical experiments involving ocean chemistry and physical oceanography.
