In this activity, students will create hanging door signs based on a traffic light. What are signs made for? What purpose do they serve?

This project was inspired by The Unstoppable Garrett Morgan by Joan DiCicco, and illustrated by Ebony Glenn. A tale of heroism and inventiveness, Garrett Morgan invented the Safety Hood that firefighters and wartime heroes adapted for use to this day. And if you rode in the car lately, you will have benefitted from his invention that created our modern-day traffic light. In this activity guide, we are taking inspiration from the traffic light to create signs that can indicate a student’s mood or set boundaries.
