Trait distributions change after an environmental shift.
Learning target
Build an initial model and explanation for: How can differential survival and reproduction change populations?
Evidence task
Record observations, questions, an initial model, and one claim that could be tested. Use these concepts where relevant: variation; heritability; fitness; selection pressure; adaptation.
Compare trait-frequency distributions across generations.
Evidence task
Show units, setup, calculation or graph reasoning, then write what the quantitative evidence can and cannot establish about: How can differential survival and reproduction change populations?
Selection simulation using paper tokens or supplied data.
Safety boundary
Use the course safety charter. If supervision, facilities, materials, or conditions are not appropriate, use the supplied-data/simulation alternative rather than improvising hazardous procedures.
Evidence task
Record variables or design constraints, procedure/model, observations/data, and one revision you would make after reviewing the evidence.
Answer the essential question: How can differential survival and reproduction change populations?
Mastery evidence
Submit a claim, at least two specific pieces of evidence, reasoning that connects them, one limitation/counterclaim, and a correction note for any essential concept below 80%.
