Creating a kidney working model using cardboard, color paper, plastic pipe, and a plastic tray to simulate urine collection can be an engaging and educational project.
Here’s a step-by-step guide to help you build this model:
Materials Needed
- Cardboard
- Color paper (red, yellow, blue, white)
- Plastic pipe or tubing
- Plastic tray or container
- Small water bottle
- Scissors
- Glue or tape
- Marker
- Ruler
- Small beads or marbles (optional, for representing waste)

1. Prepare the Base and Basic Structure
- Base Setup:
- Cut a large piece of cardboard to serve as the base of your model.
- Use markers or color paper to decorate the base to represent the body or a medical setting.
- Kidney Structure:
- Cut out kidney shapes from cardboard. You’ll need two kidney shapes.
- Use color paper to cover the kidney shapes. Red or pink can represent the outer cortex, and yellow or blue can represent the inner medulla.
2. Create the Nephrons and Tubules
- Nephrons:
- Cut small circles or oval shapes from color paper to represent nephrons.
- Attach these nephrons to the inside of the kidney structures using glue or tape.
- Tubules (Plastic Pipe):
- Cut a piece of plastic pipe or tubing to represent the renal tubules.
- Attach one end of the tubing to the top of the kidney structure (representing the collecting duct).
3. Simulate Filtration and Urine Collection
- Filtration Process:
- Use small beads or marbles to represent waste products filtered from blood (creatinine, urea, etc.).
- Place these beads or marbles into the top of the kidney model (renal corpuscles) to simulate filtration.
- Urine Collection (Plastic Tray):
- Place a plastic tray or container under the tubing to collect simulated urine (water).
- Ensure the tubing is positioned correctly so that water flows into the tray when simulated filtration occurs.
4. Connect to Water Source
- Water Bottle:
- Use a small water bottle filled with water.
- Connect a small piece of tubing from the water bottle to the top of the kidney model to simulate blood entering the kidney.
5. Demonstration and Operation
- Operational Setup:
- Tilt the kidney model slightly to simulate the downward flow of urine (water) into the collection tray.
- Explain the process of filtration, reabsorption, and urine formation as water flows through the nephrons and tubules.
- Educational Value:
- Discuss the role of kidneys in filtering waste from blood and regulating water balance in the body.
- Explain the importance of maintaining kidney health through hydration and proper nutrition.
By following these steps, you’ll create an informative and visually appealing kidney working model using cardboard, color paper, and simple materials. This project not only demonstrates the structure and function of the kidney but also engages learners in hands-on exploration of human anatomy and physiology.
