Backbone Model Human Body Science Experiment
In this fun and easy science activity, we’re going to make human backbone model.
- 24 pony tail holders – thick rubber bands will also work
- 1 pool noodle floating toy
- Exacto knife or scissors
- 1 laundry line or piece of thin rope
- Cut the pool noodle into twenty fours pieces making each piece about two inches in length.
- Tie a large knot in the end of the rope that will be big enough to prevent it from pulling through the piece of pool noodle.
- Now string the pieces together putting a pony tail holder or rubber band between each piece of the pool noodle.
- Once you have strung all the pieces together, tie the remaining end of rope into a knot that will not pull through the center of the pool noodle.
- You now have a reasonable representation of a human backbone to use as you discuss this important component of the human anatomy.
How it Works:
In this easy science activity, we used simple items to create a backbone model to better understand this critical component of the human anatomy. Our spinal column has a spinal cord. The spinal cord is represented by the rope in our model. The spinal cord is an important part of the nervous system and must to be protected.
The bones that make up our back are called vertebrate. These are represented by the sections of pool noodle in our model. There are several sections of vertebrate-neck, chest, and bottom. The twenty four vertebrae stack on top of each other with discs in between. The discs are represented by the pony tail holders or rubber bands in our model. This enables us to move in a number of ways and directions and still protects and defends the spinal cord.
