Task description
Students prepare a print or electronic presentation to report to a group of visitors to a sewage plant on their investigation into the cycling of water through ecosystems.

The completed task is expected to demonstrate the following qualities:
- ability to make inferences from observations
- description and explanation of the readily observable behaviours of water molecules in each of its states
- application of scientific understandings to a familiar natural phenomenon
