human spine science project for leanring about skeletal system

Skeletal system experiments

Before we built our bone project ideas of the human spine I tried to help them visualize two things:
  1. Without the cartilage disks our bones would get chipped (I demonstrated that by rubbing two rigatoni together and they were able to see the wear and tear on the “bone”)
  2. Without 33 independent bones working together we couldn’t bend and twist like we do (I put a sword down their back to be there solid bone vertebrae and they tried to do simple things like bend over – not so easy!!)

Skeletal system activity for kids

To help my kids understand what the spine looks like and how it functions we created this fun spine model. We use the following simple mateials we had on hand to make a really cool and memorable, EASY  spine project for kids. Here is how to create a human spine model for a science project:

  • Start with a pipe cleaner as the spinal cord
  • layers of rigatoni pasta as vertebrae (there should be 33 if you make it to scale)
  • in between each vertebrae we put a life saver gummy to represent the cartilage disks

Lego Duplo layers of bone project on human skeletal system

Bone Experiments for Kids

To help the kids visualize all the different layers in our bones we made the cross section of a bone. To make this project on human skeletal system we used:
  • red & blue pipe cleaners to represent blood vessels
  • red straw to put the pipe cleaners in to represent red bone marrow
  • yellow pool noodle to represent the spongy bone
  • Lego Duplo to represent the hard smooth compact bone (the part you actually see in a typical skeleton)
  • Gauze Wrap to represent the Periosteum (we drew blood vessels in the Periosteum with blue and red markers)
