 The moon revolves counterclockwise around the earth.  It takes about a month for the moon to go around us once… so we see each major lunar phase about once a month  You can tell time by the moon!

 UNLESS there is an eclipse, half of the Earth and half of the moon are always in shadow.  SHADE the side of the Earth that is in shadow.  Using the INNER circles on your sheet, SHADE the half of the moon that is in shadow.

 The outer circles represent what we see from Earth.  SHADE in the outer circles to represent what we see from earth.  DRAW in arrows to represent how the earth and moon rotate and revolve.

 In your diagram, LABEL the main phases… These go CCW around…  New Moon  Crescent Moon  1st Quarter Moon  Gibbous Moon  Full Moon  Gibbous Moon  3rd Quarter Moon  Crescent Moon

 What is different about the two crescent moons, two quarter moons, and two gibbous moons?  WAXING - “growing”  WANING - “shrinking”  LABEL the crescent and gibbous moons as either WAXING or WANING

 You can tell time by the moon.  What time would it be if the sun were directly overhead? FILL THIS IN  What time would it be if you were on the point on earth completely opposite the sun? FILL THIS IN  Since we go CCW around, FILL IN the missing times in 3 hour increments.

 We define “ East ” to be counterclockwise.  LABEL the Eastern and Western sides in the FULL, NEW, and QUARTER moon phases.

 Given some information that follows and your notes page, answer each question.

 If it is 6 pm and the moon is directly overhead, which phase are you observing?  FIRST QUARTER  Is the Eastern or Western side of the moon lit?  WESTERN

 If it is 6 pm and the moon is low on the Eastern horizon, which lunar phase are you observing?  FULL MOON  Is the moon rising or setting?  RISING

 If it is 6 am and the moon is just rising, where is it?  LOW ON EASTERN HORIZON  Technically, can you see the moon?  NO - THE SUN IS ALSO RISING (NEW MOON PHASE)

 If it is noon and there is a third quarter moon out, can you see it?  Possibly (the mountains may block your view)  If so, where is it?  LOW ON WESTERN HORIZON  Is the moon rising or setting?  SETTING

 If it is 6 pm and there is a third quarter moon, can you see it?  NO  Where is it?  OPPOSITE SIDE OF THE EARTH!

 Which phase of the moon can you see directly overhead at 9 pm?  WAXING GIBBOUS

 Between what times can you see a full moon?  6 PM - 6 AM  Between what times can you see a waning crescent?  3 AM - 3 PM

 Which lunar phases is visible from 9 pm - 9 am?  WANING GIBBOUS  Following from the last question, when would this phase be directly overhead?  3 AM
