How to Make a Brain Tumor Model
There are more than 120 types of identified brain tumors in existence today. A model of a brain tumor is not only a good learning and teaching tool but is also a nice addition to a science fair project or research project.
Things You'll Need:
- Wax paper
- Simple diagram of the human brain
- Photograph or illustration of the
type of tumor to be created - Several colors of modeling clay,
including red - Plastic knife
- Scissors
- Craft stick
- 1 1/2- to 2-inch diameter Styrofoam
ball - Glue gun
- Glue sticks
Cover the area where the model
will be created with wax paper. Lay supplies out for easy access.
Refer to the brain diagram as needed while constructing the model.Form two large pieces of clay into
semi-circles. These will be the left and right hemisphere of the
brain.Use a smaller piece of clay, in a
contrasting color, to create the area of the brain which connects
the two hemispheres. Attach the large pieces together without
squishing as they are two separate pieces of the brain.Roll pieces of clay into long,
rounded strips. Coil them around each half of the brain. Press
them together as you put them into place.Roll out another strip of clay.
Attach this piece between the two large halves to create the brain
stem.Shape the Styrofoam ball into the
shape and size of the tumor if needed.Flatten one side of the Styrofoam
ball for easier attachment. Hollow the Styrofoam ball from the
flattened area in if an internal view of the tumor is wanted.Roll the red clay out to create the
blood flow. Wrap it around the Styrofoam outside and in if the ball
is hollowed. Glue into place with hot glue.Attach a wooden craft stick to
allow for removal of the tumor in demonstrations.Add the tumor to the brain model,
removing a bit of clay to fit the tumor if needed.
