Inquiry eHelp Introduce, continued Connect to the Big Idea •Remind students of the Big Idea Question, How are day and night different? Discuss students' ideas about how day and night are different. Explain that the sun lights the sky during the day, so the daytime sky is bright. The sun does not light the sky at night, so the nighttime sky is dark. •Open the Science Inquiry Book to page 6.

What to Expect Students will observe pictures of the day sky and the night sky. They will create their own pictures. Then students will compare their pictures. Students should understand that the sun lights the sky during the day, that the sky is dark at night, that stars appear in the night sky (provided the sky is clear and is not flooded with artificial light), and that sometimes the moon can be seen at night and sometimes it can be seen during the day. 3 Guide the Investigation •Repeat the inquiry Question.
