Day and Night
1. How does Earth’s rotation cause day and night?
2. Why can’t we see the sun at night?

5. What is the imaginary line that goes through the center of the Earth
called?
Seasons
6. How long does it take for Earth to revolve around the sun?
7. What two things cause the seasons to happen on Earth?
8. Why do these two things cause the seasons?

10. When the Northern Hemisphere is tilted away from the sun, what season is
it in South America? Explain.
11. How do the changing seasons affect what happens on Earth?
Pattern in the sky

Lesson 4: How does technology help us learn about space?
Early Astronomers
32. In what ways were the early astronomers limited in their ability to study
space?
33. How did Galileo Galilei invention change the way astronomers could
observe objects in space?
34. Why do you think the early astronomers thought that Earth was the center
of the universe?
35. What was Galileo able to observe with a telescope that no one had
before?
36. How did the telescope change what early astronomers thought about the
universe?

about objects in space?
