Inquiry learning
How focus-shift videos reveal depth
Predict the structure from a photograph, follow the focus from front to back, assign branches to layers, and compare with a 3D model.

Combined and stacked snow crystals
Rotate and separate 1+5, 2+4 and 3+3 combined crystals, double plates, twelve-branched forms and a three-layer specimen.
