Introducing New OIA Lesson, Fracture Puzzles

We are excited to introduce Fracture Puzzles, a new lesson in The Perry Initiative’s Orthopaedics In Action curriculum! Orthopaedics In Action (OIA) is our unique, NGSS-aligned, hands-on curriculum for middle and high school STEM classrooms that features real-world challenges from orthopaedic surgery and biomedical engineering.

Fracture Puzzles can be purchased as a stand-alone lesson

or as part of a complete OIA kit.

Fracture Puzzles Case Study:
A gymnast broke her leg, and it’s your job to diagnose the fracture! In this lesson, you will explore the various ways in which bones can fracture and how the location and pattern of fracture can provide the doctors with clues to how the injury occurred. You will assemble a hands-on puzzle of a broken femur (thigh bone) and learn specific names for fracture types and locations. This lesson is appropriate for Grades 6 through 12 STEM classrooms.

NGSS Cross-Cutting Concepts & Practices:
