Biology: Ecosystem Dynamics

Students perform an in-depth investigation into the nature of ecosystems by performing the mandatory fieldwork component of their syllabus. Students learn about sampling methods and perform both a quadrat and transect study. During these scientific studies students will learn to use a range of scientific equipment to measure, observe, identify and report on biotic and abiotic factors that determine the distribution and abundance of organisms within the environment.

Lunch

Students have recess before activities and a lunch break between session 1 and session 2.

Students walk through Nattai National park to complete a belt transect. Students create a hypothesis about plant distribution and abundance along the 300m transect and collect data a part of a larger group to answer their hypothesis.

Students will also look at some trophic relationships within the eco-system.

Cost

$8 per student

Inquiry Questions

Inquiry question: How can human activity impact on an ecosystem?

Sub Inquiry Questions:

Scenario 1 What factors have led to the localised decline within the population of Feathertail Gliders within Nattai National Park?

Is it feasible to introduce a breeding population to re-establish this species within its previous range?

Scenario 2What would be the impact on the local ecosystem if Sydney Water raised the wall of Warragamba Dam by a further 10 metres?

Inquiry question: How do adaptations increase the organism’s ability to survive?

Sub Inquiry question: What are the unique features of Australian flora and fauna that allow them to adapt to the harsh Australian environment?
