Observe and Describe the Moon and Stars
•Ask: ¿Qué creen que podrían ver en el
cielo esta noche? (Possible answer: the stars
and maybe the moon) Explain that clouds block
our view of the moon and estrellas on some
nights and that bright lights can make it hard to see
the estrellas .
•Ask: ¿Verán el Sol en el cielo esta noche?
(no) ¿Por qué no? (The sun appears only during
the daytime.)
•Ask: ¿En qué se parecen la Luna y
las estrellas ? (Both can appear as bright objects
in the night sky.) ¿En qué se diferencian? (The
moon appears much larger and brighter than stars.
While there is one moon, there are many stars.
The moon is also the second brightest object in the
daytime sky.)
Making and
Recording Observations
Have students observe the moon and estrellas in
the nighttime sky tonight, or on another night when
these objects are visible. Have them record and
describe their observations in their science notebook.

nocturno? (the stars and sometimes the moon)
Raise Your SciQ!
Moon and Stars Much like the sun, the moon and many stars
appear to move across the sky. They generally appear to rise in the
east and set in the west. Other stars appear all night long but move in
a circular path across the sky. Some stars don't appear to move at all,
such as Polaris, the North Star.
The apparent movement of the sun, moon, and stars is due to the
motion of Earth. Earth rotates, or spins on its axis. As Earth rotates,
objects in the sky appear to move.
2.Compare and Contrast ¿En qué se
diferencia el cielo del día del cielo
nocturno? (The day sky can be bright; the sun
appears. The night sky is dark; the stars appear.)
¿Qué puede aparecer en el cielo durante
el día y la noche? (The moon can appear during
both day and night.)
3.Infer ¿Por qué el cielo está oscuro de
noche? (The sun does not brighten the sky
at night.)
