Weasel-style selection demonstration for variation, selection, and cumulative change.

Standards

Cumulative Selection Explorer standards and alignment

This page maps the app to standards-facing classroom use while staying explicit about model limits and evidence expectations.

Alignment Notes

  • NGSS HS-LS4-2: Explain how evolutionary processes depend on inherited variation and differential success.
  • Practices: analyzing and interpreting data, evaluating models, distinguishing useful models from overextended claims.

What learners should produce

Minimum evidence

  • A comparison of at least two runs with different settings.
  • An explanation of what cumulative selection changes in the model.
  • A clear statement of at least one important model limit.

Model limits to keep visible

  • The target is fixed in advance.
  • Correct characters are retained once matched.
  • The model is useful for discussing cumulative selection, but it is not a full biological analogue.
