By now, most people know that QR code stands for Quick Response code, and many know that they link to websites or other useful information. But many teachers still don't know what to do with them. I have had many teachers ask "How can I use it in my classroom?" I'm here to give you some ideas.
Scan a picture (or find one online) of something you would traditionally have students label (i.e. parts of a cell, human body systems, etc.) and attach QR codes to the different parts. The QR code can link to a website about that particular part, or simply text of information you would like the student to have, such as a definition or an example.
