Recognize the Shapes of the Moon
•Point to the moon in the photo on page 21. Have
students describe its shape. (Possible answers: thin;
curved; banana-shaped)
•Ask: ¿Qué diferencia hay entre esta figura
y la figura de la luna llena ? (This shape is thin
and curved. The full moon is a circle.) Discuss how
the moon appears in other shapes, too.
• Ask: ¿Qué tienen en común ambas figuras
de la Luna? (Both have the same color; both show
parts of the moon.) Explain that the moon is always
the same but the part of the moon we see changes
over the course of about a month.
Make and
Record Observations
Over the course of one month, have students invite
their parents or guardians to help them observe the
moon in the evening. Students should draw a picture
in their science notebook of their observations and
record the date.
3 Assess
1.Recall ¿Cuál se ve como el objeto más
grande y más brillante del cielo nocturno?
(the moon)
2.Explain ¿Por qué la Luna se ve más
grande que las estrellas en el cielo
nocturno? (The moon is much closer to Earth
than stars are.)
3.Draw Conclusions ¿Qué creen que es más
grande, el Sol o la Luna? (the sun)
Science Misconceptions
Moon Phases Some students may think that the moon truly changes
its shape from day to day. In fact, the moon is always the same round
ball in space.
The moon does not make its own light. It is bright because the sun
shines on it, and light reflects off of it. The sun always shines on half of
the moon, just as it shines on half of Earth. From night to night, we see
different parts of the moon's sunlit half. The different shapes we see are
called phases.
