HS-LS2-7: Human Impact Mitigation & Biodiversity Conservation
DOK Progression
Cognitive Complexity Matrix
Standard: Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.
Complexity Hierarchy: Most to Least Complex
Targeted for High School Biology / AP Environmental Science
Level 4: Create & Refine (Highest) DOK Level 4
Iterative Engineering & Multicriteria Assessment
- Design & Refine Solutions: I can design, test, and iteratively refine a scientific, physical, or programmatic solution to mitigate an anthropogenic threat to regional biodiversity.
- Multicriteria Evaluation: I can evaluate competing ecological solutions using a decision matrix balancing environmental efficacy with economic, social, and cultural trade-offs.
Level 3: Strategic Evaluation (High) DOK Level 3
Systems Analysis & Systemic Feedback
- Efficacy Assessment: I can evaluate scientific evidence regarding the long-term success of existing conservation strategies (e.g., wildlife corridors, bioremediation) on ecosystem services.
- Systemic Feedback Modeling: I can formulate an evidence-based argument to predict cascading consequences of a human disruption on regional food webs.
Level 2: Concepts & Application (Medium) DOK Level 2
Data Relationships & Component Interactions
- Interrogate Empirical Data: I can analyze population datasets, GIS maps, or biodiversity indices to establish correlations between human activities and species declines.
- Illustrate Disruption Vectors: I can construct a conceptual ecosystem model to illustrate how concrete human actions (e.g., chemical runoff, habitat fragmentation) alter system variables.
Level 1: Recall & Foundational (Least) DOK Level 1
Identification & Basic Vocabulary
- Identify Drivers: I can identify and define the primary anthropogenic drivers of biodiversity loss (e.g., habitat loss, invasive species, pollution, overexploitation, climate change).
- Define Key Terminology: I can accurately define critical biological terms, including species richness, ecosystem resilience, biodiversity hot-spots, and critical ecosystem services.
Student Pathway
Begin at the bottom (Level 1) to build background vocabulary. Work upward to Level 4 (Engineering Design) to master standard HS-LS2-7.
Teacher Instruction
Utilize Levels 1 & 2 for foundational content delivery. Reserve Levels 3 & 4 performance tasks for authentic assessments and engineering cycles.
