1900 – 1930 · Rise of the Harlem Renaissance
Invention meets movement.

Includes:
- An overview of inventions and their real-world impact
- Discussion questions linking migration, culture, and innovation
- One classroom or take-home activity
- A connection back to the Field Guide for students who want to go deeper.
