Partner students and pose the question “How do we know anything about stars that are hundreds of light-years away?” Give students the opportunity to talk to their partner about the answer to the question in a think-pair-share. Once students have had time to think and share, call on students to share what they discussed together in their groups confirm correct comments and correct any misunderstandings. Allow students time to answer the Focus Question independently on a notecard or piece of paper and have them submit it as an exit ticket.
