How to Make a Clay Model of the Urinary System
If you have a school project coming up on the urinary system, give your presentation added power by making a clay model of the urinary system. Mold your clay to mimic the parts of this system and mount them for display. The visual element will add interest to your presentation, and using modeling clay means you can make the modeled body parts as realistic as possible. You will need some basic supplies and the ability to sculpt clay in order to finish this project.
Sculpt the kidneys. Kidneys resemble beans in their shape, which is why we have a food called kidney beans. Take a ball of modeling clay and elongate it to an oval, then bend it slightly like a bean. Flatten it slightly on one side so it will lie flush against a mounting board. Repeat this for the other kidney.
Make the bladder. The bladder is a large shape resembling a light bulb; heavy and round on top, thinner toward the base. The bladder should be approximately 50% larger than the kidneys. Like with the kidneys, make the back side of the bladder flat so it will lie flush against the mounting board.
Take a ball of clay and elongate it into a skinny, narrow oval shape like a tube or a snake. Do this twice and it will resemble the ureters. Flatten them slightly.
Let all of your clay dry. Meanwhile, take a cardboard box and cut a large flat piece of it. Use a marker to draw the outline of a human body on the cardboard, from the head to the thighs. You may wish to cut that down; you will need at least the pelvic part of the cardboard "body" to be visible. Cut out this shape using scissors or a box cutter.
Glue the pieces of the urinary system in place onto the cardboard background. Glue the bladder toward the bottom, with the narrow part pointing down. Glue the tubes you made for the ureters coming out of the top of the bladder; on the opposite ends of the tubes glue the kidneys, with the bent portion facing inward for each kidney. When the glue dries your urinary system model will be ready to display.
