Compare and Contrast Size from
a Distance
•Draw a circle on a piece of paper and color it
yellow. If possible, take the class into a hallway,
or tape the paper to the board.
•Have students observe the circle. Ask: ¿Cómo el
círculo puede seguir siendo el mismo pero
verse más grande? (We could move closer to
it.) Have students observe the circle up close and
describe their observations.
•Ask: ¿Cómo el círculo se puede ver más
pequeño? (We could move farther away from it.)
Have students observe the circle from as far away
as feasible.
•Return to the classroom to discuss students'
observations. Ask: ¿El círculo cambió de
tamaño o solo pareció cambiar de tamaño?
(The size only seemed to change.) Help students
use their observations to make inferences about
the stars and the sun. Help students come to the
conclusion that the sun is about the same size as
many other stars, but it seems big because it is
closer to Earth.
Notetaking
Have students draw what the yellow circle looks like
up close and far away. Students should label their
drawings up cerca and lejos.

Differentiated Instruction
Extra Support
Have partners choose an object, such as a pencil or crayon, and observe it both up close and
far away. Have them describe and explain their observations to each other.
Challenge
Have partners draw side-by-side pictures of a familiar object from up close and far away. Then
have them write a caption that explains the difference between the two pictures.
1.Recall ¿Qué se ve más grande en el cielo,
el Sol o una estrella en la noche? (the sun)
2.Explain ¿Por qué las estrellas del cielo
nocturno nos parecen diminutas? (They are
very far away.)
3.Infer ¿Cómo creen que se verían las
estrellas si estuviesen más cerca de la
Tierra? (They would look large, like the sun.)
