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 reading QR Codes on other cards until they have found the answer. If they don’t find their answer, they go back to the original card and figure out what they did wrong.

Please note that the QR code on each card is not the answer for that card. It’s a scavenger hunt! They have to find their answer on their next card.

These problems contain a good representation of basic stoichiometry problems in assorted combinations:

Mass – Mass

Mass – Moles

Mass – Volume at STP

Limiting and Excess reactant problems

Percent Yield problems

Included in this resource:

• 36 task cards (in large and small cards, in Color or Black & White Print Options, with limiting and excess reactants/percent yield, and without limiting and excess reactants/percent yield)
• Student Answer Sheets (2)- one for basic stoichiometry cards, and one for cards with limiting and excess reactants/percent yield cards)
• Complete Key for both sets of task cards with problems completely worked out.
• Teacher Notes, tips, and strategies for setting up this activity. (2 pages)

You will want to save this lesson and use it for years to come!
