The document describes the eight phases of the moon through a series of multiple choice questions about images of the different moon phases. It explains each phase, including new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent as the moon orbits the Earth. The reader is prompted to select the correct image for each phase before moving on.

4. Which picture shows when the
moon has completed one half of its
orbit around the Earth.

5. Select the photo that demonstrates what happens
when the moon is directly between the sun and
Earth. The side facing the Earth is in darkness.

6. Which photo shows the appearance of
the moon when it has completed three
quarters of its orbit around the Earth?

7. The darkened side of the moon begins
to reappear after the full moon:

8. As the moon begins to move in its orbit
around the Earth, a sliver of the illuminated
side of the moon becomes visible.

9. Select the correct phase when the moon has
completed one quarter of its orbit around the Earth.

10. Select the correct photo of the moon as
nears the end of its orbit, and the moon
appears as a crescent shape once again.

11. Select the picture which shows the phase where a
portion of the illuminated side of the moon is
visible from the Earth as it continues to increase.

15. New Moon
- The Moon's unilluminated side is facing the Earth. The lighted side of the Moon faces awa
Waxing Crescent - The Moon appears to be partly but less than one-half illuminated by direct
sunlight. The crescent will grow larger and larger every day, until the Moon looks like the First
Quarter Moon.
First Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The right half of
the Moon appears lighted and the left side of the Moon appears dark.
Waxing Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct
sunlight. ("Waxing" means increasing, or growing larger.)
Full Moon - The Moon's illuminated side is facing the Earth. The lighted side of the Moon faces the
Earth. This means that the Earth, Sun, and Moon are nearly in a straight line, with the Earth in the
middle. The Moon that we see is very bright from the sunlight reflecting off it.
Waning Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct
sunlight. ("Waning" means decreasing, or growing smaller.)
Last Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The left half of the
Moon appears lighted, and the right side of the Moon appears dark. It will continue to shrink.
Waning Crescent - The Moon appears to be partly but less than one-half illuminated by direct
sunlight. The crescent will grow smaller and smaller every day, until the Moon looks like the New
Moon.
