3) CAN'T GET THERE?
Set up an exchange with someone who was there or who has encyclopedic knowledge of the era or topic: a relative, scholar, or friend. In my experience, witnesses to and/or experts about historical events are always eager to share their personal knowledge.
They usually do so through 1st-person anecdotal storytelling, too, which is the most compelling point of view, particularly for youth: it puts them closer to the action.
Make history personal.
4) GIVE THEM ACCESS TO THE “ALBUM"
Looking at artifacts, such as old photos, paintings, or clothing, is a great way to create associations, spark memories, and make meaning of a former time. So offer youth the stories, dress, diet, music, dance, rituals, hairstyles, living conditions, fears, hopes, etc., of those who lived through humanity’s most seminal moments. That will grab them.
Make history fun.
