Engage your students as they learn about gemstones and minerals with this QR Code Scavenger Hunt! Simply print out the mineral posters and hang them around your school or classroom. You will need to download a QR Code Scanner (there are tons of free options) onto an iPad or tablet. When students scan the code with the Ap, a website will appear with coordinating information. Students should fill out the scavenger hunt form as they find the posters.
