Lunar cycle
- 2. Light seen from the moon is reflected sunlight As moon moves around earth, different parts of it are illuminated and visible to us Different shapes of reflected sunlight are called phases
- 3. Phases of the Moon New moon – when moon is between sun and earth and not illuminated (it’s dark)
- 4. Phases of the Moon Waxing – name used when the lit part of moon is increasing Waxing-crescent phase – when a sliver of moon becomes visible
- 5. Phases of the Moon First-quarter – when the waxing moon becomes a half-circle called “first-quarter” because moon is a quarter of the way in it’s orbit
- 6. Phases of the Moon Waxing – gibbous – when the visible portion of the moon is larger than a half-circle and is increasing
- 7. Phases of the Moon Full moon – when the moon appears as a full circle Earth is between the moon and sun
- 8. Phases of the Moon Waning – when the lit part of the moon is decreasing Waning-gibbous – lit part of moon still bigger than half-circle but shrinking
- 9. Phases of the Moon Last-quarter - when the waning moon becomes a half- circle called “last-quarter” because moon is at the last quarter of the way in it’s orbit
- 10. Phases of the Moon Waning-crescent - when a sliver of moon is all that’s visible moon moves into “new moon” phase after waning crescent to begin cycle again
- 11. Earthshine on either side of a new moon, the darkened part of moon is slightly visible – “earthshine”
- 14. earthshine
- 16. Waning-gibbous
- 18. Waxing-crescent
- 20. Waning-crescent
- 22. Last quarter
- 24. Full moon
- 25. What does “waning” mean?
- 26. when the lit part of the moon is decreasing
- 28. When the darkened part of the moon is slightly visible
