When teaching human anatomy, it can be helpful to show your students models of different parts of the body, such as the brain. Brain models can be purchased at educational supply stores, but can often be quite costly. To cut down of these costs, you can make a homemade model of a brain using craft materials. To make a homemade brain model, it is important to follow a set of steps that will turn ordinary polymer clay into a small model of a brain.
Place a whole walnut onto a flat surface.
Place a butterknife into the fold of the walnut.
Press down on the butterknife using the palm of your hand to split the walnut into two halves.
Remove the walnut from inside the shells.
Press polymer clay into both halves of the shell.
Remove the polymer clay to reveal the brain shape.
Place the clay moulds onto a baking tray.
Bake the polymer clay in a 200 degree Fahrenheit oven for 10 minutes to harden it before displaying the brain models.
