When teaching students about anatomy and human biology, it is helpful to have a few visual aids to allow the students to see what different body parts and organs look like, such as kidneys. Although a human kidney is roughly the size of a fist, a smaller model of a kidney can be created out of simple craft materials. To make a kidney mold to use for making kidney models, it is important to follow a few basic guidelines.

Things You'll Need

  • Polymer clay
  • Knife
  • Large dried kidney bean
  • Cookie sheet
  • Oven

Roll the polymer clay into a quarter-sized ball.

Slice the ball in half with a knife.

Press a dried kidney bean into one half of the clay.

Place the other half of the clay on top of the first half.

Squeeze the re-formed ball slightly.

Carefully separate the halves and remove the dried kidney bean.

Place the clay halves onto a cookie sheet.

Bake the clay halves for 10 minutes in a 200-degree oven.

Allow the clay to cool completely.

Press a pea-sized amount of clay into one half of the kidney bean mold.

Place the second half of the mold on top of the first, and press them together. When you remove the halves, there will be a kidney shaped model that can be baked and used in an anatomy project.
