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.
