Unit (~7 weeks): Musculo-skeletal Unit: Prosthetics

Courses: Physiology, Anatomy, Engineering

I made & taught this physiology unit on musculoskeletal structure & function, via a sequence of inquiry tasks and engineering design challenges, supplemented by vocabulary, readings, videos, gallery walks, and interviews.

Hope the images, videos, & lab worksheets are useful/save time for folks using them! Lessons 3 & 5 need feedback and have poor slides. Some of it has messy highlighting, but I thought I'd share it now given now is a popular time for this subject to be taught. I will keep updating this post with version changes below.
