My students have been learning about how the moon changes over time. As a culminating activity we made a moon phase "chart" using a paper plate and Oreo cookies. The kids had a blast, and I think they came out great. They drew the Earth in the center of the plate, and the sun off to one side. I made them stickers for each phase that they placed on the plate in the correct position. Then, they used a Popsicle stick to shape the frosting into the correct phase shape. Next time, I will buy the knock-off Oreo's, though (they are a lot cheaper!!).
