Conduct an interview with an older relative or family friend and identify at least one then-and-now similarity and difference from it.
An interview is when you ask someone questions to learn their real story. Talking with a grandparent, or another older person you know, is a great way to learn real history from someone who actually lived it.
Good interview questions ask more than yes or no. "What games did you play as a kid?" gets a much better answer than "did you play games?"
Mastery looks like: They conduct (or report on) a real interview and can identify at least one genuine then-and-now similarity and difference.
Common stumbles: Asking only yes-or-no questions, or not asking a follow-up "why" or "what was that like" to get a real story.
