Complete activity
X05 — Components postcard exchange, 20 minutes. Materials: complete C04 and ordinary Day45, large paper component shapes. Make a postcard that explains rock components without naming them from colour. On the back leave a question about a separately unlabelled token. Invite an actual recipient or use a private imagined reader clearly labelled imagined. A possible ordinary caption says the paper components model a relationship and do not identify the minerals. Keep both surfaces part of the full source, so an attractive picture does not erase the unknowns. If a child declines writing, direct a helper through large components and confirm the recorded meaning.
