Cracking the Code

Some interesting reading on the history of barcodes opens this technology lesson. Readers find out how engineers contribute, and then they gather into groups to discuss possible improvements to our current UPC barcode system. Know that though the publisher lists national education standards met as early as third grade, this lesson would be above the heads of most third graders. Use it with a middle school STEM lesson.
