Sixth Grade: Unit 6

 Although the Sun, our moon and the Earth itself are revolving around each other we are usually not revolving in the same plane (all lined up)  But occasionally we do line up in a straight line.  When this happens, an eclipse occurs

 When the shadow of one celestial body falls on another an eclipse occurs.  A solar eclipse happens when the moon is between the Earth and the sun  Solar= EMS  A lunar eclipse happens when the Earth comes between the moon and sun.  Lunar = MES  atch?v=rVE8PFYlwSM atch?v=rVE8PFYlwSM

 Can only occur during the new moon phase  The moon passes directly between the Sun and Earth, blocking the light from the Sun  The shadow of the Moon falls on a small portion of Earth’s surface and very few people are able to see it.

 Can be seen by anyone on the night-time side of the Earth where the Moon’s not hidden by clouds.  A total eclipse of the moon can only happen when the moon is full, because that's when the moon is exactly opposite from the sun in the sky.  The moon is full about once a month, but eclipses happen less often because sometimes the moon is too high or too low for the Earth's shadow to fall on it..

..  Usually lunar eclipses (eclipses of the moon) happen two to four times a year.  Sometimes they are full eclipses, and sometimes only part of the moon is eclipsed.  When there's an eclipse of the moon, anyone on the night side of Earth can see it.

OCOTBPO&FEATURE=FVWREL&SAFETY_MODE =TRUE&PERSIST_SAFETY_MODE=1 UPCOMING LUNAR ECLIPSE  The next lunar eclipse is a partial on September 28,2015  It will be visible in both North and South America : )  Another lunar eclipse will take place on March 23, 2016  It will be best seen from the West Coast, East Asia and Eastern Australia Types of Lunar Eclipses

 During a lunar eclipse, you’ll see the Earth’s shadow creeping across the moon’s face.  The shadow will appear dark, like a bite taken out of a cookie, until the shadow completely covers the moon.  Then, during the breathtaking moments of totality, the shadow on the moon’s face often suddenly changes.  Instead of dark, it appears red.  Why?

 The reason stems from the very air we breathe.  If the Earth had no air, then Earth’s shadow on the moon during a lunar eclipse would appear black.  The presence of Earth’s air means that, during a lunar eclipse, sunlight can filter through Earth’s atmosphere onto the shadow on the moon.  This filtered sunlight makes the moon appear red during a total eclipse.

LUNAR ECLIPSE  endscreen&safety_mode=true&persist_safety_mode=1 endscreen&safety_mode=true&persist_safety_mode=1  A lunar eclipse can only occur at full moon and  In a lunar eclipse, the total phase can last for a maximum of 1 hour and 40 minutes  A lunar eclipse occurs when the Earth passes between the Sun and the Moon. SOLAR ECLIPSE  A solar eclipse can only occur at new moon  The maximum time of a solar eclipse is 7 minutes 40 seconds.  A solar eclipse occurs when the Moon passes between the Earth and the Sun

 You can experience partial and total eclipses.  Occur a few times each year.  Can only occur when the Sun, the Moon, and Earth are lined up perfectly.  Occur in lunar/solar pairs!  Caused by the revolution of the Moon.
