2How Does the Moon Move?moonThe moon revolves around the ______ while the Earth revolves around the ______!EarthsunEarthIt takes about ______ for the moon to complete one revolution around Earth!28 dayssun
3Phases of the Moon CAUSED BY: (1) Moon’s Orbit (2) Reflected Sunlight PHASES of the moon are:The different SHAPES we see each night when we look at the moon!CAUSED BY:The moon’s orbit(slightly tilted)(2) Reflected sunlight
4Get ready to “moon” yourself!!! will beEarth!(4)SUNLIGHT(3)SUNLIGHT(1)(2)SUNLIGHTUse the moon at your table as a model of the real moon & the lamp in the center of the room as the sun.CAUSED BY:(1) Moon’s Orbit(2) Reflected SunlightStand with one arm stretched out toward the “sun”, withthe moon straight in front of you, but raised up slightly.Record what you see on the moon chart in your notes.Turning counter-clockwise, stop at each of the following positions…90o, 180o, 270o… and DRAW what you see.
5Phases of the MoonYou will always see the 4 main moon phases in this order:3rd Quarter(last quarter)New Moon1st QuarterFull Moon(2nd Quarter)NO moon!DOC7 days later…7 days later…7 days later…First Quarter & Third Quarter moons are whatwe SEE as “HALF MOONS”!We call them quarter moons because the moon isONE QUARTER (1/4) or THREE QUARTERS (3/4) of the way through its 28-day cycle!
6More Phases of the Moon! Record what you see in The amount of the moon we see does not just instantly change from one phase to another after 7 days.Instead, it changes gradually (just a little bit each night).Let’s “moon” ourselves one more time…(7)(6)(8)(5)This time, also stop HALFWAY between each of the positions you stopped at before.(1)(4)(2)(3)Record what you see inthe chart in your notes.
7Using the words below, let’s see if we can name each of the NEW phases you just drew… Waxing CrescentFull Moon2nd QtrWaning GibbousNew MoonWaxing Gibbous3rd QtrLastQtrWaning Crescent1st QtrWAXING - lighted part of moon GROWING each nightWANING - lighted part of moon shrinking each nightCRESCENT - smaller than a half-circleGIBBOUS - Larger than a half-circle (egg -shaped)
8Important MOON FACTS:The moon does NOT make its own light. It reflects light from the sun.The moon is the ONLY place we have ever sent a HUMAN to….because it is the closest object to us in our solar system!The gravity of our moon is strong enough to tug the water of our planet outward causing water levels to rise & fall each day!
9Tides -the rise and fall of water every 12.5 hours Water on Earth rises for about 6 hours (HIGH TIDE), & falls for about 6 hours (LOW TIDE) in a continuous cycleThis happens twice each day!2 high tides & 2 low tides each day.The GRAVITY of the moon (and sun) PULLS on Earth’s water, creating high tides.Low TideNorth PoleHigh TideHigh TideMoonLow Tide
