When to Repair, and Why the Calendar Matters
Anatomical domain · Lesson 10 of 20 · Human Body Systems (HBS)
Today's goal: Explain why lip repair happens at about 3 months and palate repair at about 9 to 12 months, and justify the timing as a balance between safety, growth, and speech development.
This is a model of the work you should turn in. Use it to check your own: match the structure and the level of detail, do not copy it. Your wording should be your own.
Target ages: lip repair at about 3 months and palate repair at about 10 to 12 months. Palate timing: I aim before his first words because delay is associated with significant speech deficits, but not earlier than needed because palate surgery disturbs upper-jaw growth, so the window balances the speech pull and the growth pull. Non-anatomical risk: access barriers such as language or transportation can push surgery later, since minority and non-English-speaking children have reached cleft surgery measurably later, so the team will arrange an interpreter and a scheduling navigator early. Committed dates: lip repair near month 3, palate repair near month 11.
This model shows the level of evidence and organization needed to complete: A four-sentence timeline that balances the three forces and names a safeguard.
- Write one defensible claim.
- Choose specific evidence that supports the claim.
- Explain the scientific rule that connects the evidence to the claim.
Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.
The finished product above did not appear all at once. Here is the path from the question to the turned-in work, so you can follow the same steps.
- 1Start from today's question: Why are the lip and repaired at different times?
- 2Work the Model and the Explore questions to reason it out before writing anything.
- 3Pull the specific evidence the product needs from the reading and any database you used.
- 4Write it up in the required format: Set Mateo's surgical calendar for the family in four sentences: (1) state the target age for his lip and repairs, (2) justify the palate date using both the speech force and the growth force with a source, (3) name one non-anatomical thing that could push his date later and one way the team will guard against it with the disparity source, and (4) end with two committed dates, not a hedge.
- 5Check it against the rubric, then submit.
| Criterion | Proficient | Developing | Beginning |
|---|---|---|---|
| Complete | Every required part of the artifact is present and filled in. | Most parts are present, but one is missing or left blank. | Several parts are missing. |
| Accurate | The science and data are correct and match the evidence. | Mostly correct, with a small factual slip. | Key science or data is wrong. |
| Scientific reasoning (CER) | States a claim, backs it with specific evidence, and explains the reasoning. | Has a claim and evidence, but the reasoning is thin or missing. | Gives an answer with no evidence or reasoning. |
| Professional communication | Clear, organized, and labeled the way a clinician or scientist would write it. | Readable but disorganized or missing labels. | Hard to follow. |
| Submitted | Turned in through the route named under Submit here and confirmed. | Turned in, but in the wrong place or unconfirmed. | Not turned in. |
- CompleteProficient: Nothing is left blank: the model fills every part of "Set Mateo's surgical calendar for the family in four sentences: (1) state the target age for his lip and palate repairs, (2) justify the palate date using both the speech force and the growth force with a source, (3) name one non-anatomical thing that could push his date later and one way the team will guard against it with the disparity source, and (4) end with two committed dates, not a hedge.".
- AccurateProficient: Every number and claim matches the case evidence.
- Scientific reasoning (CER)Proficient: It names a claim, cites the specific evidence, and explains the reasoning, not just the answer.
- Professional communicationProficient: It is organized and labeled like a real chart note.
- SubmittedProficient: It would be attached to your class form or handed in, and confirmed.

It builds this reusable test skill: Justifying cleft surgery timing as a balance of competing forces.
- Name the concept or data pattern being tested.
- Cross out choices that violate that rule or the evidence.
- Justify the best remaining choice before checking the answer.
