Performance expectationConstruct an explanation using evidence to support the claim that the phases of the moon, eclipses, tides and seasons change cyclically.
Emphasis of the explanation should include how the relative positions of the moon in its orbit, Earth, and the Sun cause different phases, types of eclipses or strength of tides. Examples of evidence could include various representations of relative positions of the Sun, Earth and moon.
Assessment does not include mathematical computations to support explanations but rather relies on conceptual modeling using diagrams to show how celestial bodies interact to create these cyclical changes.
Every item written to HS-ESS1-7 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.

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.
