Oreo Moon Phases

Stem Activities

Ages: 3-5

Less than 30 minutes

Grownup needed

A delicious science activity that no child can resist! Children will use Oreo cookies to create moon phase diagrams and learn about the lunar cycle.

Materials Needed

  • Paper plate
  • Oreo cookies
  • Marker
  • Spoon
Arranged on a light wood-grain surface are several items, suggesting preparation for a craft or activity. A white paper plate sits to the left. Next to it is a blue-wrapped package, possibly containing a snack or art supply. A group of colorful markers with white bodies lies beside the package, and a white plastic spoon is positioned to the far right. The image conveys a sense of getting ready for a creative project.

Step-by-step tutorial

Step 1

Use a marker to draw Earth in the center of the paper plate.

Two hands are engaged in an art project on a light wood-grain table. One hand steadies a white paper plate, while the other hand uses a light blue marker to color a drawing of the Earth on the plate. The Earth is depicted with green continents and blue oceans. This scene represents a child's art activity or a craft project related to Earth Day or environmental themes.
Step 2

Split 8 Oreo cookies in half to get 16 pieces.

Two hands hold a split Oreo cookie over a white paper plate on a light wood-grain table. Several other whole Oreo cookies are arranged on the plate. One half of the split cookie displays the white cream filling, while the other half has had the filling removed, revealing the dark chocolate cookie surface. This image suggests a common practice of separating Oreo cookies to eat the filling or to use the cookie parts for other purposes, such as crafts or desserts.
Step 3

Arrange the cream-side-up Oreo halves in a circle around Earth on the plate.

On a light wood-grain table, a white paper plate displays a creative arrangement. A drawing of the Earth, with green continents and blue oceans, is at the center. Around the Earth, several Oreo cookies are placed with their cream filling facing outwards, forming a ring. A hand reaches in to pick up one of the Oreo cookies. This image likely depicts a child's craft project or a fun snack arrangement related to Earth Day or environmental themes.
Step 4

Choose one Oreo half to represent the "full moon," then use a spoon to scrape off portions of cream from the other cookies to represent different moon phases.

A white paper plate rests on a light wood-grain surface. In the center of the plate, there's a drawing of the Earth with green continents and blue oceans. Arranged around the Earth drawing are Oreo cookies, each with a portion of the white cream filling scraped away to represent the phases of the moon. This display illustrates the different lunar phases using Oreo cookies as a visual aid, likely part of a science project or educational activity.
Step 5

Draw arrows between the moon phases using the marker.

On a light wood-grain table, a white paper plate presents a visual representation of the lunar cycle. A drawing of Earth, depicted with green continents and blue oceans, sits in the center. Oreo cookies encircle the Earth, each with its cream filling partially scraped off to illustrate the different phases of the moon. A hand holding a white marker is drawing arrows around the cookies, indicating the direction of the moon's orbit and the progression through the phases. This setup clearly demonstrates the lunar cycle using Oreo cookies as a learning tool, likely for a science project or educational activity.

Now observe how the Oreo moon changes throughout its cycle!

A paper plate displays a simple model of the moon phases. A drawing of Earth is in the center, and Oreo cookies, with the cream filling modified to represent the different phases, are placed around it. Arrows indicate the direction of the moon's orbit. This visual aid helps explain the lunar cycle.
