Program

This engaging excursion in Ku‑ring‑gai Chase National Park or Muogamarra Nature Reserve allows students to investigate weathering, erosion, and human impacts on the landscape. They explore soil components and rock formations, observing how natural processes and human activity shape the Earth’s surface while developing skills in fieldwork, observation, and environmental care.

Learning intentions

Students are learning about:

Key information

Learning activities

Creating soil

This hands-on activity explores features of leaves and how their decomposition is a key to the creation of soil. During this activity, students will also investigate features of soil and the cycling of materials in soil.

Bush walk

Students will learn about the environment and the interconnected nature of invertebrates, habitat and other animals. Significant plants and animals of the local area will be identified along the walk. They will also observe evidence of weathering, erosion and deposition, including the formation of caves.

Students will learn about and observe the impacts of human activity, particularly how people's actions can affect the national park, and how the park is managed to reduce this impact.

Erosion of Earth’s layers

Using a birthday cake analogy, students will gain a clearer understanding of the different sandstone rock layers and propose erosional forces that transform these layers through an engaging activity that enables them to use the properties of the sandstone to colour.

Cultural site visit

Students will visit and Aboriginal engraving site to learn about the cultural and historical significance of the site, how weathering and erosion are impacting them and their management.
