Teacher copy: This page may include teaching prompts or answer keys. Answer keys in this public library can be viewed by anyone. Give learners a clean prompt, use checks as formative evidence, and change a case locally when prior access matters.
Goal: propose a new observable question and an adult-approved source while leaving unseen mechanisms unknown. Proposed codes: AC9SFH01, AC9SFI01, AC9SFI05. Prepare:claim/unknown, D/E, current local safety decision, Card 118.
Safety reminder · 3 min. A real accidental spill goes to the school-approved adult procedure, not a child test.
Revisit · 4 min. Identify one D appearance and one E leap beyond the source.
Model question · 5 min. Adult asks “After another equal short wait, what visible mark would be present?” rather than “Where did water disappear?”
Child try · 7 min. Card 118 routes choose a safe next observable question, one condition to hold steady and an adult to approve it; no home experiment.
Check · 4 min. If question requires touching an unknown wet material, child switches to a no-contact adult observation route or leaves it unanswered.
Exit · 2 min. Save next question/approval status, not an invented result.
