Who made the traffic signal on the corner, and how do we know? This ready-to-teach packet turns a one-minute song into three lessons on reading, history and engineering.
In Somebody Before Me: Garrett Morgan & the Traffic Signal, a curious child meets Garrett Morgan, a Black inventor from Cleveland, Ohio. After seeing a crash at a busy corner, he designed a signal with STOP and GO arms and a position that stopped traffic in every direction. Students then look at his real 1923 patent to find out how we know he invented it.
