Goal: judge whether two dated actual Science records are comparable, then make a cautious same/different/insufficient statement. Proposed codes: AC9SFI03, AC9SFI04. Prepare: two school-approved earlier records if available, compare-records, Model marks M, Card 43.
- Pair gate · 3 min. Adult checks source/date and whether both records describe the same object/property/question under relevant similar conditions; if not, label INCOMPARABLE.
- Read · 4 min. Name A/B actions and access routes exactly; if only one actual record exists, keep B NOT AVAILABLE.
- Model · 5 min. Put two invented M diagrams side by side. Teacher says their marks can be compared as drawings, but no actual plant, motion or material event is proved.
- Child try · 7 min. Card 43 routes ask what stays same/differs in actual A/B, whether the results can answer one question, or why evidence is insufficient. Do not mix model M with an actual set.
- Check · 4 min. Offer “Both pages have arrows so both real objects moved.” Child identifies diagrams/records and required actual actions.
- Exit · 2 min. Keep one bounded A/B sentence or a clear reason not to compare.
