I really wanted to use QR codes in some way this year. I created a QR Scavenger Hunt to begin my lesson on the Ozone Layer. I was really curious to know how it was going to go, and then I discover, the kids loved it!
I created it for individual use at a desk and also for an "around the room" type scavenger hunt. I decided to just have the students sit at their desk and work on these individually.
Students used the app Scan on the iPods to scan QR codes. The QR codes lead to short descriptions about the ozone layer that students recorded on their note sheet. Later, student glued their note sheet into their interactive notebooks. I also had a few students use their smart phones. The students were SOOOO excited to use the iPods as well as their cell phones to take notes. You could tell they never did anything like this before, and they want to do it again. It's funny how I tricked them...they were just taking notes :)
This activity is in my TpT store, and I definitely plan to create more!
