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 Biology: Features, Adaptations of Living Things (K, 1, 3, 7) Biology: Sensing, Organ Systems (4, 5, 6) Lessons activity is in Bones and Skeletal system Adaptations in animals: antlers, teeth and bones Resource Market Meats 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. Grades taught Gr 1 Gr 2 Gr 3 Gr 5
