Quantifying Human Impact through Mathematical Modeling

G 8 - 9

Algebra I / Integrated Math I Students

This lesson introduces students to how linear and exponential functions can be used to represent real-world environmental changes caused by human activities. Students will analyze urban development data and biodiversity indexes to determine appropriate models, interpret the meaning of slope and intercepts, and use their models to evaluate environmental planning options. The lesson emphasizes how mathematical thinking can help address sustainability challenges by modeling relationships and making evidence-based decisions.
