Modeling Kidney Function with Concentration Gradients and Selective Permeability

This kit gives students the opportunity to construct a model of a kidney and observe filtration of simulated kidney blood. Using a semipermeable membrane, students filter simulated kidney blood and test the solutions with simulated salt test strips. The simulated kidney blood also contains microscopic, simulated red blood cells that cannot pass through the membrane but are easily observable under a microscope. Kit contains enough materials for 15 groups of students.
