Celebrating National Inventors’ Day with Your Child

National Inventors’ Day provides us with an opportunity to honor inventors of the past and inspire the creators of the future. On this National Inventors’ Day, we are focusing on Black inventors who created inventions that we see and use in everyday life. We are also sharing a handful of activities you can do with your little inventor.

Inventors and Their Inventions Discussion

  • Ask your child to share what she thinks an inventor is and what an inventor does.
  • Once you know your child’s definition of an inventor, you may share more information about inventors and what they do.

Inventor: A person who invents, especially one who devises some new process, appliance, machine, or article; one how makes inventions.

Garrett Morgan: Inventor of the Traffic Light

In 1923, Garrett Morgan invented the traffic light. Cars, bicycles, horse-drawn vehicles, and pedestrians all had to share the same road. It was often quite dangerous. Morgan’s traffic signal was the first to feature three commands instead of two, which controlled traffic more effectively.

Phillip B. Downing: Inventor of the Modern Day Mailbox

Phillip B. Downing invented the street letter drop mailbox with a hinged door that closed to protect the mail. He invented this mailbox in 1891, and the design is still used today. It protects mail from theft and poor weather conditions, and it lets people mail letters without having to walk to a post office.

  • Markers
  • Craft materials – stickers, crayons, etc.
