Inquiry Case Study on Stream Biodiversity
A case study activity for 8th graders that uses Hawaiian freshwater streams to explore how biodiversity signals ecosystem health through bioassessment. Students build science vocabulary such as endemic, invasive, and bioassessment while analyzing evidence and drawing conclusions from a real-world scenario.

Teacher Guide & Tips
- Use this as an inquiry launch for a unit on ecosystems or biodiversity, pairing the reading with a 45-minute block in which students annotate the key terms before reading the case.
- Discussion question: Why might the presence of migratory species be a better indicator of stream health than the presence of a single fish species?
- Scaffold for struggling readers by previewing the Key Terms together and having students sketch the stream-to-ocean life cycle before reading the full case.
- Extension for advanced students: ask them to propose a bioassessment plan for a local waterway, identifying which indicator species they would survey and why.
- Estimated time is roughly 45 to 60 minutes for reading, discussion, and a short written response.
