1 How many trips around the Sun have you made in your life?
2 Moon Notes – page 28 1 MoonOur 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 2 The Moon's Orbit Rotation Moon is spinning on its axis Revolution The moon orbits around the EarthIt takes the moon approximately one month to go around the Earth.
4 3 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 EarthAs a result, the Moon keeps the same face toward us throughout its orbit.
5 4 PhasesThe lighted side of the moon always facesthe sun.
6 5 New MoonWhat we seeNew moon occurs when the moon is between the sun & the Earth.The shaded side of the moon is facing the Earth.What is happening from above.ESunlight
7 6 Full MoonWhat we seeThe full moon occurs when the Moon & the Sun are on opposite sides of the Earth.The lighted side of the moon is facing Earth.What is happening from above.ESunlight
8 7 Full MoonThe 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) includeJanuary Moon After Yule, Wolf Moon, or Old MoonFebruary Snow Moon or Hunger MoonMarch Sap Moon, Crow Moon, or Lenten MoonApril Grass Moon or Egg MoonMay Milk Moon or Planting MoonJune Rose Moon, Flower Moon, or Strawberry MoonJuly Thunder Moon or Hay MoonAugust Grain Moon or Green Corn MoonSeptember Fruit Moon or Harvest MoonOctober Harvest Moon or Hunter's MoonNovember Hunter's Moon or Frosty Moon,December Moon Before Yule or Long Night Moon.
9 8 Blue MoonWhen 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 9 First Quarter MoonWhat we seeThe 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.What is happening from above.ESunlight
11 10 Third Quarter MoonWhat we seeThe 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.What is happening from above.ESunlight
12 11 Waxing – light on the right! When the moon is between new & full, the visible part of the moon is increasing.This is called waxingESunlight
13 12 WaningWhen the moon is between full & new, the visible part of the moon is decreasing.This is called waning.ESunlight
14 13 Crescent Moon – less than half full Full MoonWhen the moon is between New & 1st Quarter it is called a waxing crescent.E3rd Quarter1st QuarterWaningCrescentWaxing CrescentNew MoonSunlight
15 14 Gibbous Moon – more than half full Full MoonWhen the moon is between 1st Quarter & Full it is called a waxing gibbous.Waning GibbousWaningGibbousE3rd Quarter1st QuarterWaningCrescentWaxing CrescentNew MoonSunlight

17 THINK ABOUT IT Why does the moon have phases? Are the phases of the moon caused by Earth casting shadows on the moon?How long does it take the moon to go through all of its phases?Is the moon the only object in the sky that goes through phases?Why does the moon glow?Why do we always see the same side of the moon?Why do we see the moon during the day sometimes?
