One of these two, plus the geometry diagram either way.
A single well-organized page or poster. Text, diagrams, and layout all count toward Format Execution.
Recorded narration, screen capture, animation, whatever tool you're comfortable with. Stay inside the time window — it's graded.
Every item below has to show up somewhere in your explainer — check them off as you go.
A starting point — adjust weights to fit your class before assigning.
| Category | Weight | Exemplary | Proficient | Developing | Incomplete |
|---|---|---|---|---|---|
| Geometry Diagram | 25 pts | Correctly shows Sun-Earth-Moon alignment for the eclipse type covered, including the Moon's orbital tilt relative to the ecliptic. | Alignment is correct but the tilt is missing or unclear. | Diagram present but geometry has significant errors (wrong order of bodies, wrong phase). | No geometry diagram submitted. |
| Core Explanation | 30 pts | Correctly explains why eclipses don't happen every month using the tilted orbit and nodes, with accurate solar/lunar setup. | Explanation is mostly correct but vague on the tilt/node mechanism. | Explanation attributes 'why not every month' to the wrong cause, or omits it. | No explanation of the core question, or explanation is factually wrong throughout. |
| Format Execution | 25 pts | Infographic is clear and well-organized, or video is 60–90 seconds, paced well, and easy to follow. | Mostly clear/well-paced with minor issues. | Cluttered infographic, or video significantly over/under the time target. | Format requirements not met at all. |
| Process & Presentation | 20 pts | Submitted on time, follows the content checklist, sources (if used) are credited. | Mostly complete and on time; small presentation issues. | Late or noticeably incomplete. | Not submitted. |
