Binary code is a coding system using the two digits 0 and 1 to represent a letter, number, or other character within an electronic device like a computer, ipad, etc. My niece and daughter didn’t have much experience with the binary code before they started my STEM activity. They had so much fun learning about it and making their glow-in-the-dark necklaces.

They had so much fun making these special necklaces that they decided to make some extra ones for their best friends.

You can have your students make these on string, or for ease, you can use pipe cleaners. It’s so much easier for little hands to put the beads on pipe cleaners. Here’s the finished product.
