QR Codes in MY Classroom

I feel like I can easily use QR Codes in a high school science classroom. One way would be to add QR Codes onto homework assignments that could direct my students to the section of the notes on the slideshow that applies to that section of homework. Another way would be to add a QR Code to the syllabus on the first day of class to make Syllabus Day more interesting than it normally is. There are tons of other uses for QR Codes that I will be able to discover!
