Using QR codes in the science classroom
Topic: Rocks
Equipment required: iPods and/or iPads, Rocks app, QR reader app
Activity:
1. Organise samples of basalt, granite, gabbro, geniss, phyllite, schist, slate, conglomerate,
limestone and shale to be placed around the lab. Label the samples 1, 2, 3, etc.
2. Place the corresponding QR code card next to each sample.
3. Organise students into small groups and have each group start the activity with a different
sample.
4. Each group is to read the clues on the QR code card and use the rocks app to identify the
sample rock. The group then scans the QR code to reveal the answer. The teacher may
want to use the activity sheet.
5. Each group rotates through the samples until they have completed all samples.
