What is Earth's Natural Satellite?

The moon is the Earth's only natural satellite. The changing appearance of the shape of the moon is called its phases. It takes 29.5 days to go through all of the moon phases. Oreos were used to model how much of the moon we can see. We used Oreos' "white stuff" which represented what we could see (the phase), and the chocolate represented the moon that does not actually disappear, it still there, just dark.
