Ray Bradbury in 2018

The students (7th grade ELA) and my co-teacher and I are reading Dark They Were and Golden-Eyed by Ray Bradbury. For this story, we'll read most of it aloud, and then stop at certain points and let students ask each other any clarifying questions. In the story, the Bittering family arrive on Mars and decide to establish a home there. They are then forced to stay on Mars, as the atom bombs on Earth made it so rockets cannot come back for them.

One of the questions stemmed from the line in the story that says the newspaper was warm from that day's rocket.
Here's how one of the quick conversations went:
Student 1: "Why didn't they just look on their iPad or phone?"
Student 2: "They probably didn't have wifi."
Student 1: "Why didn't they just make wifi?"
Student 3: "How do you make wifi?"

I was cracking up, and soaking it in. I love seeing their learning so visibly. I had to stop the discussion for a moment and let them know that this story was most likely written before the Internet.

They looked at me like I grew a horn. I love these kids.
