Stoichiometry Scavenger Hunt with QR Codes

UPDATE! One of my best selling resources just got even better! This resource now contains two sets of cards. Since it is near impossible to make this resource editable with the QR codes, I have added another set of cards. The original set is basic stoichiometry problems. The new set has those stoichiometry problems plus limiting and excess reactants problems, and percent yield problems. I have also included two sets of cards for each—the small original size and a large size card that shows up better on the walls. There is still the color or black and white option for each set. The Stoichiometry Scavenger Hunt with QR Codes will be a great activity for review, reinforcement, or review before state test. Tape the task cards around the room. Then assign partners to work together making sure one of the partners has a cell phone with a QR Code reader. Assign each partnership duo a card to start with. Once they get their answer, they will move through the room rea
