Program overview
The Cause and effect in freshwater ecosystems excursion is a Stage 6 Investigating Science program for Module 1 and 2. Bring scientific inquiry to life in this Stage 6 Investigating Science fieldwork program, where students explore two contrasting aquatic environments at Simmos Beach Reserve on the Georges River. These sites provide an ideal context for examining natural and human influences on water quality, biodiversity, and freshwater ecological health.
Across the day, students apply the Working Scientifically skills central to Module 2 as they observe environmental features, identify patterns, and make inferences that lead to testable hypotheses. Students consider risks, follow ethical fieldwork practices, and design investigations that generate valid and reliable primary data.
Fieldwork activities include:
• conducting multi-sensory observations to identify natural and anthropogenic features influencing each site
• assessing risks and planning safe, ethical fieldwork practices
• measuring key water quality parameters to explore cause-and-effect relationships in freshwater ecosystems
• investigating biodiversity through standardised macroinvertebrate sampling methodologies
• using data to evaluate impacts on aquatic health and ecosystem function
• drawing evidence-based conclusions about environmental condition, pollution sources, and ecological implications.
Through this immersive investigation, students gain practical insights into freshwater ecosystems while strengthening their ability to question, predict, plan, conduct, and evaluate scientific investigations in authentic field contexts.
Maximum two classes per day.

Observations and Inferences
Inquiry question: What inferences can be drawn from observations?
Students:
-
conduct a collaborative practical investigation and collect a range of qualitative and quantitative primary data from one of the following:
