Complete activity
X06 — Storeroom base card, two 15-minute sessions. Materials: complete Day46, familiar cm ruler and large plain-paper rectangles only if local adult approves. Choose diagram explanation or actual-paper comparison. Write the exact base question and source/mode. For actual work record a prior prediction, matched ruler/orientation, procedure and obtained readings; stop if alignment is uncomfortable or unsafe. For the supplied drawing use 4/6 cm with its identity, never pretend to predict an already supplied outcome. Make a useful size card with a boundary about hardness and real-rock dimensions. A possible diagram explanation compares T and S by 2 cm; actual-paper work must keep its own different results.
