Unit 2: Phase 2: Biological Explanation and Controlled Intervention
Duration of Days: 16
Students will know how the nitrogen cycle functions in aquatic systems, including the role of nitrifying bacteria.
Students will understand how ammonia is converted to nitrite and nitrate.
Students will understand how nutrient accumulation affects algae growth and system stability.
Students will recognize how intervention strategies influence ecosystem balance.
Students will construct nitrogen cycle flow diagrams.
Students will connect parameter data to biological mechanisms.
Students will analyze causes of algae blooms.
Students will research possible interventions and evaluate trade offs.
Students will implement a controlled intervention and monitor system response.
