Oreo Phases of the Moon

Mrs. Bachman’s science students are learning about the phases of the moon with the help . . . of Oreos!

They first considered how the moon can look different – sometimes it’s fully round, sometimes it’s just a sliver, and often it’s somewhere in between.

How can we see the moon at all? We see it when it reflects the sun’s light. So, as the moon rotates around the Earth, the sun lights up whatever side of the moon is facing it. From our position on earth, we see whatever portion of the moon is reflecting the sun’s light.

Using their textbook as a guide, Mrs. Bachman’s students scraped the frosting off of Oreo halves to depict the different phases of the moon.
