This document discusses the importance of water quality measurements like temperature, pH, and mineral content. It outlines a lesson plan where students: 1) Collect field readings for temperature, pH, and minerals at a local body of water. 2) Graph and analyze the data to interpret conditions and make predictions. 3) Potential extensions include assessing the impact of acid rain on aquatic life and connecting the findings to broader ecosystem studies.

- 1. Frank Martin Water
- 2. Significance • Irrigation • Drinking • Recreation • Transportation • Energy
- 3. Temperature
- 4. Significance • Freezing • Algae production • Stability for organisms • Pollution
- 5. pH
- 6. Acid Lake • What happens when a lake turns acidic? • How can you measure acidity? • What causes a lake to turn acidic? • What can be done once a lake turns acidic?
- 7. Mineral • Test the hardness of water • Identify different mineral in water • Are they healthy? • What was their source? • Process of water cleansing
- 8. Materials Laptop and data probe and all the necessary sensors.
- 9. Authentic Annual Observation • Have class observe conditions at body of water annual. Preferably one that has significance to the community. • Students form three person teams and collect readings for temperature, pH, and minerals. • Students graph data, interpret and make predictions. They also learn more information about key area in their community.
- 10. Extension • Assess the affect of acid rain on aquatic invertebrates. • Determine if the pH level has affected other organisms in the ecosystem. • Describe how the prescience or absence of aquatic invertebrate can help assess water quality.
- 11. Multi-Unit • This lesson provides the opportunity to extend to temperature laboratories in the class room. • There also is the opportunity to continue with laboratories dealing with pH and mineral composition. • Students also could study the auatic invertebrate in detail and under microscopic view.
