The human brain is the most complex internal organ in the human body. It is the key element of the nervous system. Making a clay model of a human brain can help a child understand the basic anatomy of the brain. A child can examine a clay model brain to become familiar with where the structures are actually located in a real human brain. Using an illustration of the brain and some clay, you can show a child how to make a human brain out of clay.
Download a picture of a human brain online and print it, or view a three-dimensional image of a brain online. You can also borrow a human anatomy book for reference.
Make the right and left hemispheres of the brain. These are the largest parts of the brain. Shape the clay according to the illustration.
Make the corpus callosum using a different colour clay. The corpus callosum connects the right and left hemispheres. Mold a piece of small clay according to the illustration and place it in the middle of the hemispheres. Mold the right and left hemispheres together.
Make the gyri (gyrus singular) and sulci (sulcus singular). The gyri are the "bumps" and the sulci are grooves that are seen on the surface of the brain. Use your finger or the eraser end of a pencil to create these bumps and grooves. Use the brain illustration as a guide.
Create the cerebellum by forming two small balls of clay and squish them together. Attach the cerebellum where you see the cerebellum on the illustration of the brain.
Create the brainstem. The brainstem is the portion of the brain that connects to the spinal cord. Roll up a small piece of clay and form it into the shape of a flower stem. Stick the brainstem in between the cerebellum. Use your illustration as a reference.
