What are the Phases of the Moon?

To start, the phases of the Moon are the different ways the Moon looks from Earth over about a month!

As the moon orbits around the Earth, the half of the moon that faces the sun will be lit up. The different shapes of the lit up portion of the moon that can be seen from the Earth are known as the phases of the Moon.

Each phase repeats itself every 29.5 days. There are 8 phases that the moon goes through.

The Moon Phases (in order):

NEW MOON: A new moon cannot be seen because we are looking at the unlit half of the Moon.

WAXING CRESCENT: This is when the Moon looks like a crescent and gets bigger in size from one day to the next.

FIRST QUARTER: Half of the lit portion of the Moon is visible.

WAXING GIBBOUS: This occurs when more than half of the lit portion of the Moon can be seen. It gets bigger in size day by day.

FULL MOON: The entire lit portion of the moon can be seen!

WANING GIBBOUS: This occurs when more than half of the lit portion of the Moon can be seen but it gets smaller daily.

LAST QUARTER: Half of the lit portion of the Moon is visible.

WANING CRESCENT: This is when the Moon looks like a crescent and gets smaller in size from one day to the next

Oreo Phases of the Moon

Let’s dig into the cookie bag and learn about the different phases of the moon and what causes us to see only part of the moon at certain times of the month! 

This fun Oreo moon phases activity lets kids combine a fun snack with simple astronomy.


Note: This Moon phases project can be easily done with construction paper!

  • Oreo cookies or similar generic brand
  • Paper plate
  • Marker
  • Plastic knife, fork, or spoon (for carving out the moon phases)
  • Glass of milk (optional for dunking the Moon)


STEP 1: Open up a pack of cookies and twist eight cookies carefully apart.

STEP 2: Use the edge of a fork to draw a line down the center of the icing, carefully scrape off half the icing, and set it onto the top of the paper plate to begin your first quarter Moon cycle. 


STEP 3: Work from left to right on your cookie moon cycle, with the next being waxing gibbous. Use the fork to draw the line, scrape off the icing, and set on the left of the first quarter Moon. 


STEP 4: Work your way around: full Moon, waning gibbous, third quarter, waning crescent, new, waning crescent, and back to the first quarter. 


STEP 5: Once all the Oreo Moon’s are on the plate in a circle, carefully draw the Earth in the center with markers. 

STEP 6: Use a marker or pen to write which Moon phase each cookie represents next to the appropriate Moon cookie model.
