If I was a Chemistry teacher & cell phones weren’t against the rules in our school, I would TOTALLY put up a big poster like this in my room!
QR Code Periodic Table with Symbols
Each element is a QR code that, when scanned, takes you to a video about that element. Amazing!
Oh, AND it’s available for download as a HUGE image (that you could probably print out and hang in your classroom).
