Scan Barcodes Day 4

Lesson Summary:

Students use light to guide Edison.

What You'll Do:

Program your robot to follow a light. Younger students can scan the barcode or students can write their own code. Students can create a map for their robot to follow or they can lead their robot through a cave. With multiple pieces of paper have students each create their own section of a cave and they can connect them to create their own giant cave system for their robots to go through. Alternatively students could build a blanket fort cave for the robots to follow them through.



  • Chromebook or other computer (If they are coding)

  • Print out of the barcodes (If you decide to use these)

  • Edison Robot (1 per student)

  • Legos & tray (1 per student)

  • Flashlights (Marine Habitat Koa on the STEM shelf)
