Bone slice puzzle and structure

Summary: 
Look at the structure inside a large animal bone. If a long bone can be made into slices, students can assemble them into a complete bone.
Science content (2016 curriculum): 
Biology: Features, Adaptations of Living Things (K, 1, 3, 7)
Biology: Sensing, Organ Systems (4, 5, 6)
Resource: 
Materials: 
  • Cow bone, sliced into sections (by butcher) and cleaned (with H2O2)
Procedure: 

Assemble the slices of bone into a complete bone. Cues to how they fit together include the outside shape of the bone, the placement of the marrow hole, spongy bone and the hole for a blood vessel.

Bone slices like this can be used to make prints, if you are willing to let them get inky.
