1. Learning Target: I can analyze how rotation affects the phases of the moon.
DO NOW:
5 minutes
Over the course of a month, the appearance of the moon will change. Why does this happen?

2. The Moon
Our planet's large natural satellite, the Moon, is the easiest astronomical object to observe.
The only "scientific instrument" you'll need at first is a pair of eyes.

3. The Moon's Orbit Rotation: Moon is spinning on its axis Revolution:
The moon orbits around the Earth
It takes the moon approximately one month to go around the Earth.

4. Why do we never see the DARK SIDE?
Synchronous Rotation is the reason we never see the “dark side” of the moon.
Over the millennia, the Moon has become "locked" into a special kind of motion around the Earth.
It rotates on its axis at the same pace as it revolves around the Earth
As a result, the Moon keeps the same face toward us throughout its orbit.

5. The lighted side of the moon always faces the sun.
Phases

The full moon is given different names, depending on when it appears. For example, the "Harvest moon" is the full moon that appears nearest to the Autumnal Equinox, occurring in late September or early October. Some other full moon names (by month) include:

February Snow Moon or Hunger Moon
March Sap Moon, Crow Moon, or Lenten Moon
April Grass Moon or Egg Moon
May Milk Moon or Planting Moon
June Rose Moon, Flower Moon, or Strawberry Moon
July Thunder Moon or Hay Moon
August Grain Moon or Green Corn Moon
September Fruit Moon or Harvest Moon
October Harvest Moon or Hunter's Moon
November Hunter's Moon or Frosty Moon,
December Moon Before Yule or Long Night Moon.

9. Blue Moon
When there is more than one full moon in a month, the second moon is called a blue moon.
A blue moon happens every two years on average.
The phrase, “Once in a blue moon” means very rarely or very seldom or almost never.

10. First Quarter Moon What we see
The First quarter moon occurs when the moon is halfway between new and full.
As seen from the Earth, half the moon’s disk is illuminated.

11. Third Quarter Moon What we see
The Third or last quarter moon occurs halfway between the full moon & the new moon.
As seen from the Earth, half the moon’s disk is illuminated.

Waxing is when the moon is between new & full, the visible part of the moon is increasing. E

13. Waning
Waning is when the moon is between new & full, the visible part of the moon is decreasing. E
