Using Oreo biscuits, model divergent, convergent, and transform plate boundaries as demonstrated in the video linked by the QR code.

I cannot directly answer question 2.4 as it requires scanning a QR code to view a video and then performing a physical activity using Oreo biscuits. To answer this question, you would need to: 1. Scan the QR code provided in the image to watch the videoclip. 2. Follow the instructions in the video to model each type of plate boundary (divergent, convergent, transform) using Oreo biscuits. This typically involves using the two biscuit halves as plates and the cream filling as the asthenosphere. That's 2 down. 3 left today — send the next one.
