The phases of the moon are caused by the changing orientation of the illuminated half of the moon relative to the Earth as the moon orbits our planet. There are eight phases of the moon: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent. As the moon revolves around Earth, the portion of its surface that is illuminated by the sun varies based on its position.

1. Phases of the Moon

2. What can you see
in the sky during
night time?

3. What is the
shape of the
moon?

4. The shape of the moon is round.
However, its shape seems to
change from time to time. There
are times the moon looks round
as a plate. Sometimes it appears
like a banca/boat. These
apparent changes in the moon’s
shape are called phases.

5. Let us look at
this illustration of
the Phases of the
Moon.

6. What did you observe?

7. The moon is a familiar object in
the night sky. It is the only satellite
of the Earth. A satellite is an object
in space that revolves around a
planet. The moon as the Earth’s
natural satellite makes a complete
rotation in one complete revolution
around the Earth in 29 ½ days.

8. The moon does not produce its own
light. It only reflects the light coming
from the sun. It appears differently at
different times because the
illuminated portion on the moon
changes as it revolves around the
Earth. The apparent change in its
appearance is known as the phases
of the moon.

9. Let us watch this video
presentation.
Listen carefully and
take down notes the
important details.

16. Waxing
Crescent

17. How about this phase
of the moon?

18. Waxing
Gibbous

visible, but it is not quite

•This phase includes the
night after the first quarter
to the night before the full
moon.
