This tutorial will show you how to make a kidney working model for a science exhibition at your home. Kidneys are vital organs in human beings. It is a bean-shaped organ located below the rib cage.

The kidneys are a part of the urinary system, and each kidney removes waste and extra fluid from the body by filtering the blood. Nephrons are an essential part of each kidney.


To make the kidney working model, we need;


  • Cardboard
  • Hot glue gun
  • Pencil
  • Straw pipes
  • Color papers
  • Scissor
  • Glue
  • Plastic bottle
  • Box cutter
  • White paper
  • Pen

Steps To Make Kidney Working Model

Step 1: First, cut these structures from the cardboard and paste colorful paper respectively:

  • Kidney – Purple
  • Ureter – Blue and Red
  • Urethra – Yellow

Step 9: Now, put the base of the bottle in the bottom and stabilize the model in the stand you make.

Kidney Working Model For Science Exhibition

Now the model is ready to represent in the science exhibition.


Kidneys receive the blood for filtration from the arteries and its main function is to remove the waste products from the body. With this working model of the kidney, the students will know the functioning and working of the kidney and how it can be made at home by easily available material.

Things To Remember

  • Work carefully and slowly during the cutover.
  • To protect your work surface, use a self-healing mat.
