I’ve always been a fan of science activities that you can eat. One of my favorites is the Oreo Cookie Moon Phases activity. It’s almost as if Oreo cookies were made for this lesson, and it’s a great way to learn how to match a moon phase name with a moon phase appearance.
You will need:
- An Oreo cookie for each moon phase
- A Popsicle stick or other tool for scraping the frosting
- The free PDF (link below) with the moon phases
What to do:
Separating Oreo cookies while keeping the frosting intact is a fun challenge. I like to slowly twist the Oreo to maximize the amount of frosting on one side, Cooling the cookies in the refrigerator can make it easier, but then you wouldn’t be able to eat the mistakes.
After twisting, hopefully most of the frosting will be on one side or the other. You can always transfer frosting if needed.
Use the above image, (or download the PDF below) to show how the moon changes from new moon, to full moon, and back every 28 days. Recreate each phase in cookies and frosting, and then snack on the results. Science is yummy.
