Bone slice puzzle and structure

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)
  • Cow bone, sliced into sections (by butcher) and cleaned (with H2O2)

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.

Bones in activity:

Head of left humerus, partial.
From (see caudal (from back) view).

Central section of femur.

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