💡 Big idea: Bone repair follows a predictable four-stage process driven by the same cells studied Tuesday; technology choices depend on fracture severity.

  2. 8-25Notes: four repair stages with cell activity at each
  3. 25-45PLTW task: research one repair technology

Mr. Mendoza's 5-minute intro
  • Yesterday you classified fractures. Today you learn what happens after the break. Bone heals, but only if the conditions are right.
  • The four stages of healing map directly onto the bone cells you learned Tuesday. This is the payoff of that chart.
  • You will also evaluate one repair technology and write a CER claiming when it is the best option. Your CER needs a specific fracture type as the patient scenario.
  • This content is high-yield for the Human Anatomy and Physiology emphasis on the WebXam. Know the stage names and the cells involved.
Do this, step by step
  1. 1Read the notes on the bone-healing stages: hematoma, soft callus, hard callus, remodeling.
  2. 2Match each stage to the bone cells most active during it.
  3. 3Research one repair technology (casting, plates, or bone graft) from the PLTW task.
  4. 4Write a CER claiming when that technology is the best choice.
  5. 5Submit your repair-stage diagram and technology CER.
You'll be able to
  • You can sequence the stages of bone repair.
  • You can justify when a given repair technology is appropriate.
Know by the end
  • The four stages of bone repair: hematoma formation, fibrocartilaginous callus (soft callus), bony callus (hard callus), and bone remodeling.
  • Osteoblasts are most active during callus formation; osteoclasts dominate the remodeling stage.
  • Repair technologies range from immobilization (casting/splinting) to internal fixation (plates, screws, rods) to biological augmentation (bone graft).

Day 4 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.

Do this: Complete the bone-repair and repair-technology task in Lesson 1.1 Beginning with Bones on myPLTW; work through all screens during the 25-45 minute window.

Complete

Mark the repair task complete after submitting your repair-stage diagram and CER.

How far to get

Fracture task is done; today the bone-repair task should show complete and your diagram and CER should be submitted.

What to do if you were absent

If YOU are absent

Today is individual PLTW work, so do exactly what we did in class, from home: complete the same PLTW target above, then submit your CER.

Open Schoology (CMSD) and keep going

How to get there: open the CMSD website, click Clever, sign in with your Microsoft (district) account, then open Schoology from Clever.

If MR. MENDOZA is absent

Class still runs. Complete the online activity above (it's self-guided). Need the concept taught without a teacher? Use this authoritative explainer:
