C.) Phases
New Moon
Moon phase that occurs when the Moon is between Earth and the Sun, at which point the Moon cannot be seen because its lighted half is facing the Sun and its dark side faces Earth.
Solar Eclipse
Occurs when the Moon passes directly between the Sun and Earth and casts a shadow over part of Earth
Constellations
Patterns in the stars named after animals, fictional characters, or objects
Eclipse
When a shadow is cast by the Earth or Moon
Waxing Moon
When the Moon appears to get bigger
Waning Moon
When the Moon appears to get smaller
Axis
a real or imaginary line that a spinning object turns around
Revolution
is a complete pass around the sun
Rotation
is a complete spin on the axis
Star
is a sphere of hot gases that gives off light
Apparent motion
is the way something appears or seems to move (As the Earth rotates from east to west the sun and stars appear to move even though they aren't.)
Lunar Eclipse
the blocking of sunlight to the moon that occurs when Earth is directly between the sun and the moon
Polaris
the north star - located in the constellation Ursa Minor (The Little Dipper)
Orbit
the path a revolving object follows
Crescent Moon
the phase of the moon in which only a curved edge of the moon's side that faced earth is illuminated, lasts about 6 days, can be a small sliver or almost a quarter moon.
Gibbous Moon
when the size of the illuminated portion of the moon is greater than half but not a full moon, lasts about 6 days can be almost all white or just a little more than 1/2 white
