This is intended for a middle school 1:1 classroom. The students use the pass when they need to go to the bathroom. They simply scan the QR code and fill out the form quickly, leave the pass on their desk, so I know they are gone and leave. Upon their return they scan it again and fill the form out. This helps with documenting who goes to the bathroom and when, especially if there runs into an issue in the bathroom or you are trying to get data on one particular student. Of course, you will have to change the QR Code, so it is linked to a Google Form that you created on your account. You can make your own QR code by simply going to https://www.qr-code-generator.com/ . Enjoy!
