Oreo Moon Phases

Easy
Oreo Moon Phases | Science Fair Projects | STEM Projects
Explore the fascinating phases of the Moon with Oreo cookies! Learn why the Moon looks different every night and make delicious models of the moon phases by removing the filling!

Hypothesis

The hypothesis is that the different phases of the moon can be represented with oreo cookies.

Method & Materials

You will use Oreo cookies to make edible Moon models, scraping off the filling to create the New Moon, First Quarter, Full Moon, and Third Quarter phases. Compare them to see how the Moon changes shape.
You will need Oreos, a popsicle stick or kid-friendly knife and two plates.

Results

As the Moon orbits the Earth, it appears to change shape because of the sunlight reflecting off its surface. By creating edible Moon models, it becomes clear how the Moon's phases change.

Why do this project?

This science project is fun to do because it combines a snack with astronomy. It allows you to visually and tastefully explore the phenomenon of the Moon's phases, making it an engaging learning experience.

Also Consider

Observe the Moon in the sky and compare it with the Oreo models to see the similarities and differences between the real Moon and the edible representations.
