The Standard
Create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity.

What This Standard Means
What Students Need to Do
- Students identify a human-caused threat and a proposed way to reduce it. They build or revise a simulation that compares current conditions with the proposed solution. They collect repeated outcomes and judge effects on species survival or genetic variation.
What Mastery Looks Like
- A student can build a model with a clear threat, proposed solution, baseline, variables, and measurable biodiversity outcome. They use repeated results to judge the solution, then revise the model or solution based on evidence and limits.
Common Misconceptions
- Students may assume any conservation action will help every species. They may treat one simulation run as proof or assume a model predicts the future with certainty. They may track total population but ignore genetic variation or effects on other species.
How to Assess It
- Exit ticket: A new road splits a frog habitat. Sketch a 20-frog simulation comparing no crossing with a wildlife tunnel, then name the measured outcome and one revision.

Ways to Teach It
Use colored beads as animals and paper habitat patches to test whether adding a corridor changes survival across ten migration rounds.
Write a claim choosing a mitigation plan, then cite simulation results and explain one limit that could change the decision.
Play a population card game with drought, road, and disease cards, then revise one rule to model a chosen protection strategy.
Map a local development site and build a spreadsheet comparing species survival with native planting, fencing, or a wildlife crossing.
