Quick facts for the back… • Wax means to get bigger • Wane means to get smaller • Wax on/wax off (visibility begins from the far right and gradually increases until a full moon is reached. After it is reached, the right side fades away until the next new moon. • Moon phase completion takes 29 days and 12 hours completing a Lunar Calendar.
Phases of the Moon New Moon Waxing crescent Less than a quarter of the moon is visible The visible part slowly becomes larger You see the moon from the right side with light Backwards “C” • Moon lies between the sun and the Earth • Side facing Earth is dark • Moon is NOT visible (EXCEPT during a Solar Eclipse)
