Read one chunk, wait for response. Sign/AAC/exact description/director route welcome; do not read every adult safety/source field aloud.
Ask before we try
“What would you like to find out about this paper roof? What do you think might happen? It is fine to be not sure. An adult will try only if the setup is approved.”
Look at this try
“First we notice the unloaded roof. Now the adult gently places one light card. What did you notice? Did it match your prediction, differ, or stay unclear?” This is an invitation, not a supplied outcome; say NOT TRIED if no actual action.
Tell a small true idea
“What happened in our try, or what does the invented notebook report? What would you like to ask next?” Keep actual source/access/support clear privately; one useful idea is enough.
