Talk with your students about life before they were born. Discuss how our grandparents lived through events in history that will never happen again and changed the world because they happened. Some things to bring up are U.S. landing on the moon, John F. Kennedy getting shot. Things in history affect us all and change our thoughts and feelings in many ways. Have all the children in your classroom think about and talk about a person in their family that they could talk to about doing an interview with.
