Crack the Code: Secret Language of Computers

Overview

Discover the secret language of computers by creating a bracelet that spells your name—or a special message—in binary code. Using two colors of beads to represent 0s and 1s, you’ll learn how computers communicate and make your own unique wearable message from another world.

Duration

15 - 30 minutes

Materials (per student):

• Beads (3 colors)

• Binary Code Key Chart

• Elastic String

• Activity Worksheet

• Pen/Marker

• Scissors

Instructions:

1. Pick your name or a short word to encode. The word should be max 5 letters.

2. Use the Binary Code Key to write out the 5-digit binary code for each letter of your word. (Example: A = 00001)

3. Pick three bead colors. One color bead will represent “0”. Another color bead will represent “1”. The last color bead will be your spacer between each letter.

4. Start stringing beads for your first letter’s binary code (one bead = one digit). Use all 5 digits per letter. Add a spacer bead between each letter.

5. When you're done, tie off your string to complete your bracelet!

6. Bonus: Try decoding someone else’s bracelet
