Seagrass meadows - What is seagrass?

In this activity the students will investigate seagrass as a marine plant. The students will investigate the life cycle of seagrass, the structure of seagrass and what adaptative features that seagrass have to help them survive life on the coastal fringe.  How does seagrass survive out of water on low tides? What types of structural adaptations does the seagrass have to help it live in an aquatic marine ecosystems as a flowering plant? If seagrass is a plant does it have flowers?  These questions will help uncover why is seagrass important in coastal ecosystems? The students will create a mini poster of a seagrass plant, naming and drawing the different parts.  Using a whole class venn diagram compare and contrast the different parts of a seagrass compared to a land plant.

A catchment story of a river

In this session students uncover the catchment 'story of a river'. The students take part in a hands on interactive activity which tells the story of a river as it moves from the source to the sea highlighting the importance of an estuary and bay areas.  Along the way the river is impacted by many different types of land use  including farming for agriculture, roadways, townships and industrial areas.  The students add different mystery canisters to the river basin and observe the effect this has on the river along its journey to the sea. Discussing the impacts that this has on the health of the river and the sea.  What is a catchment? What types of land uses are found along the river course? How does this change the water quality as the river flows to the sea? Do we see all of the impacts? What impact do you think has the biggest impact? Why?

What are marine mammals?

In this session students investigate the key characteristics of classification of mammals.The students explore the different groups of marine mammals found in our worlds oceans, including whales, porpoises and dolphins (Cetaceans), seals, sealions and walrus (Pinnipeds), dugongs and manatees (Sirenians), and polar bears and otters (Fissipeds).What are the features that group them together to form the Marine Mammals?  Students use a KWL chart and/or create a simple visual planner to identify key features of groups and what sets them apart from each other.  AusVELS level 3, 4, 5, 6  Biological Science.

A seagrass meadow.

Students investigate life in a seagrass meadow. The seagrass meadow story begins to share simple interactions in a seagrass meadow community. Students are invited to draw the illustrations for the seagrass meadow story.  The students start with the book script and add their own pictures. The focus in on a Dugong and some other inhabitants of the meadow. The story introduces concepts of  basic needs of living things, external features and having offspring. The story includes discussion of human induced impacts on the Dugong poplutation. 'A seagrass meadow' written by Tracey Gray and illustrated by students. This is a good way to start exploring seagrass communities with early years students and integrates environmental imagination as a centerpoint of science understanding and connection.
