Program

Gibberagong Environmental Education Centre offers a curriculum-aligned Stage 5 Geography excursion exploring Sustainable Biomes through hands-on fieldwork at Bobbin Head. Students investigate the characteristics of contrasting mangrove and dry sclerophyll forest biomes, collect and analyse environmental data, and examine how human activities influence ecosystem health and sustainability. Through mapping, field sketches, water quality testing and geographical inquiry, students develop practical fieldwork skills while exploring Aboriginal Peoples' sustainable use of local environments and supporting the NSW Geography syllabus.

Learning intentions

Students are learning about the main characteristics that differentiate the world’s biomes

Key information

Learning activities

Understanding biomes

Students will develop their geographical skills using maps to investigate the distribution of biomes within the local landscape. Using area and grid references, contour interpretation and vegetation maps, the students will identify how mangrove ecosystems occupy low-lying tidal zones, while temperate forest (dry sclerophyll) dominate higher ridgelines.

A field sketch overlooking the creek enables the students to explore human impacts on these biomes, including infrastructure such as seawalls and picnic areas, and the strategies used by National Parks to manage these environments sustainably.

Water quality fieldwork

Students will use fieldwork equipment to test the oxygen saturation, phosphate level, turbidity and pH of the water in the catchment. Students will analyse their data to determine the quality of the water, to explain how these indicators influence aquatic life and to suggest management solutions to improving water quality.

Comparing mangrove and dry sclerophyll biomes

In this hands-on investigation, students will collect and then compare data collected from two contrasting biomes – mangrove and temperate forests Working in small groups, they collect data on air and soil temperature, humidity, wind speed, gradient, aspect, forest structure, leaf characteristics, soil type, and soil pH. This activity deepens students’ understanding of how biophysical elements shape and support specific biome types and ecosystems and encourages them to synthesise information and consider how natural and human factors affect biome resilience and sustainability.

Aboriginal Peoples' knowledge of biomes

Students explore Aboriginal knowledge and sustainable use of local biomes through a cultural investigation of middens, bush tucker, traditional tools, and fire management practices. Students learn how Aboriginal Peoples have long understood and managed these environments for food, medicine, tools, and cultural renewal. This activity highlights the importance of traditional ecological knowledge in understanding and sustaining Australia’s diverse biomes.
