Performance expectationUse models to illustrate how human reproduction and development maintains continuity of life.
HS-LS1-8 is unique to New York State — it does not appear in the national NGSS set for Biology, which is why practice material for it is so hard to find.
Emphasis is on structures and function of human reproductive systems, interactions with other human body systems, embryonic development, and influences of environmental factors on development.
Assessment does not include the details of hormonal regulation or stages of embryonic development.
Every item written to HS-LS1-8 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.
Developing and Using Models
Phenomenon stimulus, connected items across the required types, answer key, rubric and figures drawn deterministically from a structured spec — in the format your students will sit.
