Description
In this outdoor Field Study, students compare the ecological health of two freshwater sites based on macroinvertebrate biodiversity found using leaf packs.
GOOGLE DOC & easy to use GOOGLE SHEETS INCLUDED!
- Also includes Quizlet Set and other Resources!
STEPS:
- Collect leaves and place them in a mesh or coconut fiber bundle (leaf pack).
- Students place the "leaf pack" on the bottom of a freshwater stream.
- Students will return to the sites to collect the leaf packs after 1-3 weeks. Bins, dissection trays, etc. needed to hold leaf packs.
- Students will identify macroinvertebrates using the guides. Tweezers and gloves are helpful as they sort through the leaves. Magnifying glasses, macrolenses, or dissecting scopes are also helpful.
- The Biotic Index Google Sheet will automatically calculate Pollution Tolerance Index (PTI) Score and EPT Richness Index
- The students will work together to analyze the data, produce graphs, and answer conclusion questions on a Google Doc.
GOOGLE DOC includes:
- Background Information
- Easy Hypothesis Selections via Google Doc
- Google Sheet (via link to make a copy) for collecting data, producing graphs, and calculating Pollution Tolerance Index (PTI) Score & EPT Richness Index
- Conclusion Questions
- Resources:
- Link to Quizlet Identification Set
- Links to Macroinvertebrate ID Guides
- Links to Leaf Pack Network where detailed "How To Guides" can be found.

Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales. Examples of mathematical representations include finding the average, determining trends, and using graphical comparisons of multiple sets of data. Assessment is limited to provided data.
