Are you studying adaptations with your students? Have you considered mangroves as a focal point?
About 11,000 kilometres (or over a million hectares) of Australia’s coastline is covered with mangrove forests making them one of Australia’s most geographically widespread ecosystems. This area represents the third largest area of mangroves in the world.
In Western Australia, mangroves occur naturally in most coastal areas from Shark Bay northwards. There are also small mangrove communities at the Abrolhos Islands, and in the Leschenault Inlet in the state’s south west.
In Activity 1 of the Marine WATERs Lesson Plan: Life in the Mangroves, students will study what mangroves are. You may wish to use our new Fisheries Fact Sheet: Mangroves, the Poster: The Mysteries of Mangroves and Article: Masters of Adaptation to help facilitate your class discussion. Then, in Activity 3, students will investigate mangroves as a habitat using a story about a barramundi life cycle. Our Poster: Barramundi Life Cycle will help you to explain the different stages of the life cycle as you work through the story – your students will particularly like the part where the barramundi changes sex from male to female! In Activity 4, students will use the mangrove ecosystem they created in Activity 3 to develop their knowledge of food webs (for more information on food chains and food webs, check out the Marine WATERs Lesson Plans: SEE Food & Marine Connections).
