Students will use fieldwork instruments to measure abiotic and biotic factors while assessing owl habitat quality in Field of Mars Reserve

Ecosystems excursion | Stage 4 | Science excursion | Field of Mars EEC

Program overview

Ecosystems is a Stage 4 Science excursion where students take on the role of ecologists in a case study on conserving the powerful owl. Through habitat assessment, abiotic and biotic sampling and food web investigations (including analysis of owl pellets and animal evidence), students use data to evaluate habitat quality and the role of urban bushland in supporting biodiversity.

Inquiry questions

Fieldwork activities

Habitat assessment

Students will utilise fieldwork instruments to sample a variety of critical abiotic and biotic factors in the Field of Mars Reserve. They will use their data to evaluate the reserve's suitability as a roosting and nesting site for owls.

Animal survey and food web construction

Students will analyse pellet samples to identify the food sources of the powerful owl. They will also survey the reserve for evidence of animal presence and use the collected data to construct a food web of the ecosystem. This will enable students to determine whether the habitat can support populations of powerful owls.

"The program was well organised, not rushed, pitched well to our students’ ability."

Content

Living systems

Ecosystems

  • Identify the components that make up an ecosystem
  • Investigate the interactions of biotic and abiotic factors in an ecosystem
  • Identify how matter and energy are cycled through an ecosystem
  • Create a food web and ecological energy pyramid based on local area observations to describe how matter and energy move through an ecosystem
  • Examine secondary-source data on the factors that change populations, including the introduction of a new species to an ecosystem, to identify trends, patterns and relationships, and draw conclusions
