# C07 · Two voices for the visitor

Prepare two speech bubbles, ground view and explanatory model. Fictional visitor's ground notes say the same invented pattern was beside the left roof-outline mark at model time a and above centre at time b in the same fixed frame that evening. A paper maker separately turns an unshaded marked Earth disk beside a fixed facing guide. Ask for the two different messages. Worked example: “The supplied ground notes changed against the roof frame. The turning-Earth model helps explain a changing ground view.” It doesn't prove a current local path or stars fixed in space. Finish with source/model labels. Next help: let the child choose a simpler picture-free retelling.
