- Welcome · 3 min. Show an empty box image and the same box with a square inside. No real object is filmed.
- Model · 4 min. Place EMPTY first; a viewer might read arrival. Reverse panels; a viewer might read departure.
- Try together · 5 min. Ask which pictures stayed and which feature changed: their order.
- Child choice · 7 min. Child chooses order for a fictional paper parcel story and gives a possible reason.
- Notice · 4 min. Record panel order and child intended reading. Do not insist on a single viewer interpretation.
- Close · 2 min. Keep both variants; tomorrow the drawn frame can include less context.
