Healing Initial Model

1.B Develop an initial model of the healing process within and between multiple interacting systems and subsystems that restores the foot’s function.

If students need support in choosing what to put in their models, refer them back to the Healing Timeline we developed as a class. Ask what they think might be happening with each part of the foot between when the injury happened until the student could walk again. Ask what was different in the parts of the foot right after the injury and after it was healed.

Students might include parts of the foot without representing how the parts interact or work together. If you notice this, remind them that we can also think about what’s going on inside the foot and underneath the skin because x-rays allow us to see some internal structures. Prompt them to include how the parts were interacting during the events in the Healing Timeline, and what we might see if we could look inside the foot at these interactions.

Healing Initial Model handouts can be collected (at the end of the class) and used as a formative pre-assessment. They can help identify what science ideas students are bringing into this unit and where students are in their development of the practice of modeling.
