Luna – Earth’s moon named after Roman Moon Goddess same age as Earth – 4.6 billion years old most likely made of rock material from Earth Moonlight is not produced by the moon. Moonlight is reflected sunlight. The Sun is the source of the light. http://youtu.be/2iSZMv64wuU tour of the moon 4 ½ min http://youtu.be/tbARBWtmb_c 3 ½ min Mystery of the Missing Moon

Moon Phases http://youtu.be/nXseTWTZlks 3 min History Channel - Phases http://youtu.be/EG10fxvMjAA 4 min – music only Moonlight Sonata by Beethoven As the moon orbits (revolves) the Earth, we SEE different parts of the half lit moon. The different shapes (parts) are called the moon’s phases. Waxing – lit portion of the moon that seems to be getting larger Waning – lit portion of the moon that seems to be getting smaller

Moon Phases Because Earth rotates, your part of the Earth faces the moon once a day. No matter where you are on Earth, the moon phase will look the same. http://youtu.be/3tHVRS2vJi0 2 ½ min A Year in the Life of the Moon http://youtu.be/7JqVqvIlrwA 3 min Time Lapse explains Libration

Waxing getting bigger light is on the right Waning getting smaller light is on the left born dying

New Moon Completely dark Moon is located between Earth and the Sun. The entire lit side is facing away from Earth. Beginning of the Lunar Cycle

Waxing Crescent Curved shape Getting bigger LIGHT is on the RIGHT

First Quarter Half of the bright side is visible The moon has completed one-quarter of a full revolution around the Earth. LIGHT is on the RIGHT.

Waxing Gibbous Bulging More than half is lit LIGHT is on the RIGHT.

Full Moon Completely lit up Moon is halfway through its orbit around the Earth. ALL of its lit side is facing the Earth.

Waning Gibbous Bulging More than half is lit Getting smaller LIGHT is on the LEFT.

Third Quarter Sometimes called Last Quarter Moon has completed ¾ of a revolution around the Earth. LIGHT is on the LEFT.

Waning Crescent Curved shape Getting smaller LIGHT is on the LEFT.
