HS-LS1-4Mitosis and Differentiation

Performance expectation

Use a model to illustrate cellular division (mitosis) and differentiation.

What NYSED says about assessing it

Clarification statement

Emphasis should be on the outcomes of mitotic division and cell differentiation on growth and development of complex organisms and possible implications for abnormal cell division (cancer) and stem cell research.

Assessment boundary

Assessment does not include specific gene control mechanisms or recalling the specific steps of mitosis.

The three dimensions

Every item written to HS-LS1-4 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.
