Bone model from recycled materials

This week, I was teaching at our home education group about bones. We use the Apologia Exploring Creation with Human anatomy and physiology book. We had finished the skeletal system chapter and I wanted to pull some of the learning together with a model.

I had found a model on Pinterest but didn't possess any pipe insulation nor any suitable pipes. So I decided to create my own model from items around the house.

A roll of play dough made good red bone marrow although yellow would have done equally well for yellow marrow. Our playdough did have some glitter in it hence the slightly flecked appearance.

Red wool represented blood vessels.

This was covered with bubble wrap to represent spongy bone

 and then cardboard tubing for compact (cortical) bone.

I glued some muslin onto the outside of the cortical bone for periosteum.
The red wool on the outside is the blood supply to the periosteum.

Simple and made from items from around the house.
