Learning Experiences

Geographical Tools
Students will use a variety of geographical tools to acquire, process and communicate geographical information such as maps, surveys and fieldwork instruments e.g. water testing instruments.
Lagoon Foreshore Survey – Kayak

Students will participate in a lagoon foreshore survey by kayak to evaluate management issues for the lagoon.

They will paddle to numerous locations and take note of human impacts, native vegetation, weeds, fauna sightings and the dominant vegetation community.

Some of the management issues discussed will include clearing of riparian vegetation, acid sulphate soils and

the endangered Grey Headed Flying Fox community

Water Quality Assessment
Students will use water testing equipment to measure the quality of the water in Avoca lagoon, assess its condition with past water quality results and discuss ways of improving water quality.
Endangered Green and Gold Bell Frog Investigation
Bareena Wetland is adjacent to Avoca Lagoon and is one of the few remaining locations where the endangered Green and Gold Bell Frog can be found. Students will discuss why Bareena Wetland is an ecosystem at risk and assess the suitability of the site for the frog by analysing the salinity, water depth, water temperature, pH and vegetation.
