Science Academic Vocabulary Tierra
1 Introduce
Tap Prior Knowledge
Ask students to review what they already have
learned about the sun. Discuss how the sun lights the
sky during the day, seems to move across the sky,
and does not appear at night.
Set the Purpose and Read
Read the heading on page 16 aloud. Tell students to
listen as you read to find out more about the sun.
2 Teach
Read Aloud and Discuss
•Read pages 16–17 aloud. Have a volunteer point
to the sun in the photo and read the label. Say: El
Sol es una estrella. Then ask: ¿Qué diferencia
hay entre el Sol y las estrellas que vemos en
la noche? (The sun is much closer to Earth than
other stars are. It is the only star we see during
the day.)
•Flip back to pages 14–15. Have students compare
the photo of stars on these pages with the photo
of the sun on page 16. Ask: ¿Qué diferencia hay
en el aspecto del Sol con el de las estrellas
que vemos en la noche? (The sun looks much
larger and brighter.)
•Discuss how the stars at night look so tiny
because we are so far away from them. Say:
Si estuviéramos mucho más cerca de las
estrellas que vemos en la noche, también
se verían grandes y brillantes en el cielo.

Science Misconceptions
Sun and Stars Some students may not recognize the sun as a star, or
they might think that the sun is an unusually large and bright star. In fact,
the sun is a star, and it is a typical star in many ways. The sun appears
large and bright only because it is relatively close to Earth.
Although stars may appear white in the night sky, some are yellow or
orange like the sun. Other stars are blue, white, red, or other colors.
