Function: We are going to simulate a kidney filtering urine.
How it works: We are going to use a coffee filter to simulate how a kidney will filter out urine.
Materials: Coffee filter, cup, water
Construction plan: We are going to pour water and dirt into the coffee filter and show how it filters it out.
Biology principles: The coffee filter is able to filter liquid just as the kidneys are able to filter out blood.
Unresolved issues: There are no unresolved issues.
Function 2: We are going to take a balloon and fill it with liquid like a bladder holds urine. There will be a straw or tube which will simulate the urethra.
Functions: It will hold and spray out the “urine”, representing the liquids leaving the body.
Materials: Balloon and liquids
Construction plan: We are going to pour water in a balloon and spray it like it’s a bladder.
Biology principles: Bladders hold urine like a water balloon holds water.
Unresolved Issues: None
