Performance expectationUse mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
Examples of mathematical representations could include finding the average, determining trends, and using graphical comparisons of multiple sets of data.
Assessment is limited to provided data.
Every item written to HS-LS2-2 has to assess all three dimensions together, not the content alone. This is the structural change that made older practice material stop matching the exam.
